Definitions
- the present invention relates to a transgenic animal model system basecl on the development of transgenic mice bearing components of the human immune system, including large numbers of innate lymphocytes such as mature human natural killer (NK) cells, ⁇ T cells, and NK-T cells as well as adaptive CD4 and CD8 T lymphocytes.
- the invention further relates to the utilization of said model system to screen for, or identify, compounds that modulate (increase or decrease) the number and/or activity or maturation of natural killer (NK) cells or other innate lymphocytes.
- Such compounds may be used in immunotherapies for treatment of pathogenic diseases, cancer, autoimmune, infectious and inflamatory diseases, immunideficiency and for treatment of transplant patients.
- the invention further relates to the use of the animal model system of the invention, wherein the immune system of the animal has been stimulated by IL-15, to generate antibodies, including monoclonal antibodies, against any antigen of interest.
- the present invention is based on the discovery that innate cells in general and NK cell differentiation and expression of killer-like inhibitory receptors (KIRs) in particular as well as adaptive CD4 and CD 8 T cells in humans are all regulated by IL-15 mediated signal transduction that operates in a species-specific fashion where human IL- 15 -responsive cells require human IL-15/IL- 15R ⁇ complexes.
- KIRs killer-like inhibitory receptors
- Natural Killer cells participate in host protection by eliminating cells with altered expression of self-MHC-I which can result from viral infection or transformation (1). While a role for viral and stress-induced ligands in NK cells activation is appreciated, the best described regulatory mechanism of NK cell activity is the expression of inhibitory receptors for self MHC-I ligands by mature NK cells with high cytotoxic potential. In man, killer-like inhibitory receptors (KIRs) recognizing classical MHC-I molecules HLA-A, -B or -C are expressed on the predominate peripheral NK cell (CD56 lo CD16 + ) subset which possess abundant intracellular perforin and granzymes and display spontaneous cytotoxicity (2, 3).
- KIRs killer-like inhibitory receptors
- NK cells expressing at least one KIR recognizing self MHC-I have a lower threshold of activation and appear more functional than NK cells expressing no KIRs or those only expressing KERs recognizing non-self MHC-I ligands (8, 9).
- This phenomenon termed “licensing” or “disarming” has been well characterized in mice (10) and suggests a role for KIR-self MHC-I interactions during human NK cell development.
- KIR + NK cells are present in these patients indicating that normal MHC-I expression itself is not required for KIR expression.
- KBR transporter associated with antigen processing
- NK cell development requires IL-lSR ⁇ expressing cells to chaperon IL- 15 to the surface where it is bioactive and significantly more potent in inducing activation and proliferation of IL- 15 -responsive cells. This concept is called IL-15/IL- 15R ⁇ "trans-presentation" (14, 15).
- Both WO2007/001677 and WO2007/046006 disclose that combinations of IL-15 and IL-lSR ⁇ , or complexes of fragments thereof, are capable of modulating an immune response in a host.
- IL-15 appears to have a minimal effect on NK cell homeostasis in vivo (16, 17).
- NK cells are dramatically reduced in patients carrying mutations in the common gamma chain ( ⁇ c ) cytokine receptor (used in IL-15/-7/-4/-9/-2 and -21 signal transduction), Jak3 or the shared IL-2/15R ⁇ , while they are present in IL-7R ⁇ -deficient patients suggesting that IL-15 may regulate human NK cell development (18, 19).
- ⁇ c common gamma chain
- Jak3 the shared IL-2/15R ⁇
- H ⁇ S human immune system
- a recently developed HIS-mouse model is the engraftment of newborn Balb/c Rag2 ⁇ /" ⁇ c "/” mice with human hematopoietic stem cells (HSC) from fetal liver, cord blood or adult bone marrow (20, 21).
- HSC human hematopoietic stem cells
- Balb/c Rag2 "/" ⁇ c "/” HIS mice represent a practical HIS model with high human chimerism, most lymphocyte lineages generated, adaptive immune responses occasionally evoked and unlike earlier models do not develop thymomas (20-23).
- T cell homeostasis involves the generation of new T cells in the thymus, the survival and proliferation of T cells in the periphery and the differentiation from na ⁇ ve to effector or memory [51].
- TCR T cell receptor
- pMHC self-peptide + MHC
- cytokines cytokines
- IL- 15 is a peculiar cytokine because it requires expression of the IL- 15R ⁇ chain by the same cell in order to be functional.
- IL- 15 such as monocytes, dendritic cells and stromal cells must also express the IL-15R ⁇ in order to trans-present IL- 15 to IL- 15 responsive cells (expressing the IL-2R ⁇ / ⁇ c complex), and both IL- 15 and IL-15R ⁇ are up-regulated on myeloid cells following inflammation, thereby increasing IL- 15 bioavalability [63-65].
- mice lacking these proteins have reduced numbers of memory CD8 T cells (most notably the CD122 hl subset), NK T cells and ⁇ / ⁇ T cells in the periphery [66 f 67].
- memory phenotype CD8 T cells fail to proliferate and survive when adoptively transferred into IL- 15 deficient mice demonstrating a direct role for IL- 15 in their homeostasis [60, 68].
- H ⁇ S human immune system
- the mouse thymus is seeded with human T cell progenitors that are able to be positively selected and differentiate into mature CD4 and CD8 T cells capable of migrating to secondary lymphoid organs indicating that a level of cross-reactivity between murine-derived IL-7 and pMHC exist [69-71],
- the number of peripheral T cells observed in Balb/c Rag2 "A ⁇ c "A HIS mice is limiting and despite exhibiting an abnormally high turnover rate, T cells fail to accumulate with time suggesting T cell survival and homeostasis is not optimal [69-73].
- HIS Balb/c Rag2 "y" ⁇ c "A mice engrafted with fetal liver HSCs a new in vivo role for human IL- 15 trans-presentation in human T cell development and homeostasis has been identified.
- Human IL- 15 trans-presentation in HIS mice increases na ⁇ ve CD4 and CD8 T cells, accelerates thymopoiesis providing increased peripheral T cells after hematopoeitic stem cell transplantation and results in higher immunoglobulin production against specific antigens after immunization.
- This discovery provides a HIS model system for use in identification or generation of novel drags or antibodies for use in immunotherapies designed to treat a variety of different diseases and disorders.
- the present invention relates to a transgenic animal model system based on the devlopment of mice bearing components of the human immune system, including innate lymphocytes such as mature human natural killer (NK) cells, ⁇ T cells, and NK-T cells as well as adaptive CD4 and CD8 T lymphocytes.
- innate lymphocytes such as mature human natural killer (NK) cells, ⁇ T cells, and NK-T cells as well as adaptive CD4 and CD8 T lymphocytes.
- the invention relates to immunodeficient mice which are genetically deprived of T, B lymphocytes and NK cells and which have been engrafted with human hematopoeitic stem cells.
- the transgenic mice may further be transgenic for expression of human HLA class I and/or HLA class II molecules.
- mice In such transgenic mice, the maturation of innate lymphocytes in general and NK cells in particular, as well as adaptive CD4 and CD8 T lymphocytes, is induced through administration of IL- 15 /IL-15R ⁇ agonists, thereby providing humanized mice having large numbers of innate human lymphocytes in general and human NK cells in particular and adaptive CD4 and CD 8 T lymphocytes.
- Such mice provide a humanized immune system model to study activity of innate human lymphocytes in general and human NK cells in particular and adaptive CD4 and CD8 T lymphocytes in vivo.
- the transgenic animal model system of the invention provides a system for identification of novel drugs for use in immunotherapies designed to treat a variety of different diseases and disorders including but not limited to infectious disorders, cancers, autoimmune and inflammatory diseases, immunodeficiency and for treatment of transplant patients.
- the animal model system of the invention provides a means for assaying the efficacy, toxicity, or side effects of newly developed immunotherapies including, for example, that of vaccines.
- the animal model system of the invention may also be used to determine the mechanism of action of such immunotherapies.
- the transgenic animal model system of the invention also provides a system for generating new therapeutics.
- IL-15 stimulated HIS mice of the invention may be used to generate, for example, new monoclonal antibodies against any antigen of interest following immunization.
- the present invention is based on the discovery that IL- 15/IL- 15R ⁇ trans- presentation promotes NK cell maturation, innate lymphocyte development as well as CD4 and CD8 T cell homeostasis. Accordingly, the transgenic animals of the invention may be used for screening for compounds that modulate the activity, or level of expression, of IL- 15 and/or IL- 15 Ra, thereby regulating the maturation of NK cells, CD4 T cells and CD8 T cells. Such compounds may be used in immunotherapies for treatment of pathogenic diseases, cancer, autoimmune, infectious and inflamatory diseases and for treatment of transplant patients. In a preferred embodiment of the invention, complexes of IL-15/IL-15R ⁇ that act as agonist on IL-15-responsive human cells are used. The composition can be administered as a therapeutic to treat an existing condition or as a prophylactic in advance of developing a condition.
- FIG. 1 NK cells develop and populate to various lymphoid tissue in HIS-mice.
- A 8 weeks following CD34 + CD38 ⁇ HSC engraftment, various organs from HIS -mice were analyzed for human NK cell reconstitution by flow cytometry (human CD45; hCD45). FACS plots are representative. Values represent mean percentage ⁇ s.e.m of 8 mice.
- B Cellularity of the indicated organs was enumerated and the number of hCD45 + cells determined based of flow cytometry data. Numbers of cells in bone marrow (BM) are per femur and blood are per ml. Values represent mean ⁇ s.e.m. of 8 mice.
- Human NK cells were analyzed in the thymus (C) and (D) spleen or bone marrow by flow cytometry using antibodies against the indicated human antigens. Events shown were pre-gated on hCD45 + . FACS plots are representative of 8 HIS-mice, with a total of 3 different donor HSCs represented.

- mice C57BL/6 mice were purchased from Harlan (France).
- mice were backcrossed onto the Balb/c background and Rag2 " " ⁇ c " " mice on a Nude background were maintained in isolators with autoclaved food and water.
- Mice with a human immune system (HIS) were generated as previously described (20, 21). Briefly, newborn (3 - 5 day old) Rag2 '/" ⁇ c "/” mice received sub-lethal (3.3 Gy) total body irradiation from a Cs source, and were injected intra-hepatic (i.h.) with IxIO 5 sorted CD34+CD38- or 5xlO 5 CD34+ human fetal liver cells. All manipulations of HIS mice were performed under laminar flow.
- HIS-mice were injected intra-peritoneally with lOOul of either human IL- 15 (2.5 ⁇ g), human IL- 15Ra-Fc (7.5 ⁇ g) + human IL-15 (2.5 ⁇ g) both from R&D Systems (Minneapolis, MN), 2.5 ⁇ g RLI(29) or PBS alone commencing at a minimum of 6 weeks after reconstitution.
- lOO ⁇ l of 10mg/ml of BrdU from BrdU flow kit (BD Bioscience, CA) was injected IP daily 2 days prior to sacrificing mice.
- NK cell transfer assays 3 x 10 4 CD56 hi CD16TOR ' or 2 x 10 5 CD56 ?0 CD16 + KIRs NK cells were sorted from human CD45 + CD3 " fetal splenocytes (15 weeks gestation) and transferred i.h into 1 week old sub-lethally irradiated Balb/c Rag2 "/" ⁇ c ⁇ / ⁇ mice. A cocktail of KIR antibodies recognizing KJR-2DL2/3/1/-2DS1/2/4/-3DL1/S1 was used. Recipients were then treated i.p with PBS or 2.5 ⁇ g of RLI on day 0 and day 4 post- transfer.
- IL-15 in vivo neutralization was performed by i.p administration of 50 ⁇ g of goat anti-human IL-15 or 25 ⁇ g of goat anti -mouse IL-15 both from R&D Systems (Minneapolis, MN) every second day for 7 days.
- Intracellular staining was performed after fixation and permeabilization of the cellular suspensions using BD Perm/Wash and BD Cytofix/Cytoperm reagents from BD Bioscience (San Jose, CA) according to manufacturer instruction.
- BrdU detection cells were incubated for 1 h at 37 0 C with 30 ⁇ g DNAse from BrdU flow kits (BD Bioscience, CA). All washings and reagent dilutions were done with PBS containing fetal calf serum (FCS). All acquisitions were performed using LSRII, Canto 1 or Canto 2 cylometers, cell sorting was performed using FACS ARIA, all machines were interfaced to the FACS-Diva software (BD Bioscience).
- NK cells were purified from donor blood buffy coat prepared by density gradient centrifugation over Ficoll-Hypaque (Nycomed Pharma, Roskilde, Denmark) using anti-CD56 magnetic beads (Miltenyi Biotech, Auburn, CA). C57BL/6 splenic NK cells were purified by anti-DX5 magnetic beads (Miltenyi Biotech, Auburn, CA).
- Purified cells were loaded with 5 ⁇ M CFSE (Molecular Probes) and cultured at 2 x 10 5 cells/ml in RPMI with 10% FCS and lOng/ml rhIL-15 (rhIL-15; R&D Systems, Minneapolis, MN) or 30ng/ml rmIL-15 (Peprotech) for 3 or 5 days.
- 1 x 104 CD56+ NK cells purified from human peripheral blood were labeled with CFSE and cultured for 72 hours in combinations of human or murine IL-15 which had been pre-incubated with human or murine IL-15Ra-Fc for 1 hour at 4°C.
- IL- 15 and IL- 15Ra-Fc were 5ng/ml and 20ng/ml respectively.
- In vitro re-stimulation of HIS-derived NK cells was performed using CD56 + NK cells purified by magnetic beads (Miltenyi Biotech, Auburn, CA) from a cell suspension of spleen and bone marrow from 7 HIS-mice pooled together.
- NK cells were cultured at 2.5x10 5 cells/ml in RPMI supplemented with 10% FCS, rhIL-15 (5 ng/ml) and either rhIL-12 (5 ng/ml) + rhIL-18 (20 ng/ml, R & D Systems) or 2.5xlO 6 K562 cells/ml (ATCC) for 18 hours with brefeldin A (Sigma) added for the last 4 hours of culture.
- Retroviral Bcl-xL expression Human fetal liver cells were prepared and modified by retroviral transduction as follows. The Sorted CD34 + CD38 " fetal liver cells were cultured overnight in IMDM (Invitrogen) supplemented with Yssel's medium, 5% normal human serum, 20ng/mL human stem cell factor, 20ng/mL human thrombopoietin and 20ng/mL human interleukin-7 (PeproTech, Rocky Hill, NJ).
- NK cell specific antibody anti-NK ⁇ 46
- human NK cells were identified in all lymphoid organs of HIS-mice although at low frequencies, typically between 0.3% to 1.5% human lymphocytes (Fig. 1 A). Both CD56hiCD16- and CD561oCD16+ NK cells subsets are present, with the majority of NK cells having the latter phenotype (Fig. 1 C). Some CDIo + cells expressed CD56 at levels indistinguishable from non- NK cells.
- CD5 ⁇ l0 cells are NK cells as they express NKp46, NKG2D, CD94 and like their counterparts in man, express KIRs whereas CD56 hl CD16 " cells are rarely KIRs + (Fig. 1 C).
- NKp46 + cells present a phenotype consistent with peripheral NK cells in man including expression of CD 122 (IL-2RJJ), NKG2A, CD 161, but not CD3 (Fig. 1 D).
- IL-2RJJ CD 122
- NKG2A CD 161, but not CD3
- Fig. 1 D In vivo generated human NK express high levels of intracellular granzyme-B and IFN- ⁇ when stimulated with IL- 12 and IL- 18 ex vivo, and de- granulate when co-cultured with K562 human leukemia cells as determined by expression of CD 107a (Fig. 1 E).
- IL-15 is a pleiotropic cytokine essential for murine NK cell development.
- HIS-mice represent a hybrid human-murine system where cytokines receptors compatibilities between species may not exist.
- human IL-15 ML- 15
- ML- 15 induces survival and proliferation of murine NK cells (24)
- IL-15 induces survival and proliferation of murine NK cells (24)
- NK cells cultured in vitro with hIL-15 proliferated extensively (predominately the CD56 bl CD16 " subset) which was in contrast to those cultured in murine IL-15 (mIL-15) which itself sufficiently induced proliferation of murine NK cells (Fig. 1 F and Fig. 7).
- mIL-15 murine IL-15
- Fig. 1 F and Fig. 7 murine IL-15
- mIL-15 failed to induce human NK cell proliferation, although some cells survived when mIL-15 was combined with hIL-15R ⁇ -Fc (Fig. 1 G).
- hIL ⁇ 15R ⁇ was clearly superior in inducing NK cell proliferation compared to mIL-15R ⁇ when combined with hIL-15 (Fig. 1 G).
- activated human but not murine myeloid cells were able to induce human NK cell proliferation in vitro (Fig. 7), which is consistent with previous studies(26).
- IL- 15 While IL- 15 is known to heighten NK cell cytotoxicity and induce proliferation, it also protects cells from apoptosis (the latter possible at lower concentrations) by suppressing pro-apoptotic Bim and elevating Bcl-2 family members such as Bcl-xL and McH (32-35).
- Bcl-2 family members such as Bcl-xL and McH (32-35).
- a clear in vivo effect of RLI and IL- 15+IL-l 5Ra-Fc was the up-regulation of Bcl-xL in NK cells (Fig. 2 B and E). It was next asked if enhanced survival could improve NK cell reconstitution in the limiting ML- 15 environment of HIS-mice.
- HSCs were infected with a bicistronic retrovirus encoding the pro-survival protein Bcl-xL and GFP (to detect infected cells) in vitro prior to engrafting newborn Balb/c Rag2 "/" ⁇ c "/” mice.
- Ectopic expression of Bcl-xL in human HSCs resulted in a significant increase in thymocyte and splenocyte cellularity eight weeks after engraftment, with Bcl-xL transduced cells (GFP+) representing a greater proportion of hCD45 + cells compared to control transduced cells in all organs (Fig. 3 A 5 B and C).
- NKp46 + cells were significantly increased in thymus and spleen of Bcl-xL HIS-mice compared to control HIS-mice, however this appeared to be primarily a result of increased cellularity in these organs as the percentage of NK cells largely unchanged (Fig. 3 D and E).
- a greater proportion of NK cells were GFP+ in Bcl-xL infected mice compared to controls, no accumulation of Bcl-xL expressing NK cells was observed amongst the most mature subset (CD56 lo CD16 + ).
- IL- 15 itself is known to enhance NK cell cytotoxicity via up-regulating effector molecules such as IFN- ⁇ , perform and granzymes at the level of transcription and/or translation and by increased surface expression of LFA-I and IL-12RB1 (37-39). Strikingly, amongst the enhanced CD16 + population following IL- 15 trans-presentation treatment, the percentage of NK cells expressing KJRs was also significantly elevated resulting in a large increase in the KIR + NK cell pool, an effect again more prominent with RLI (Fig. 4 A). The fraction of KIR + NK cells following exogenous IL- 15 trans- presentation was typically highest in the thymus and elevated compared to normal frequencies in human blood (typically 50-60%).
- NK cell subsets had a similar level of incorporated BrdU during treatment (Fig, 5 A). While one cannot distinguish between CD16 + NK cells that have incorporated BrdU and BrdU+ cells that have up-regulated CD 16, it is most likely that the latter accounts for most of the BMU + CDIo + NK cells as CD56 l0 CD16 + NK cells are refractory to IL- 15 stimulation in vitro (40, 41), especially when compared to CD56 hl CD16 ⁇ NK cells (Fig.
- Binding of IL- 15 to NK cells ultimately activates signaling pathways stemming from STATS phosphorylation such as activation of NP- ⁇ B, induction of cyclin D, down-regulation of pro-apoptotic proteins and up-regulation of Bcl-2 family members, cytolytic granules and the transcription factors Ets-1 and T-bet (34, 37, 42, 43). While it is clear how these signaling events promote cell division, survival and effector functions it is not known how these pathways regulate acquisition of KIRs.
- IL- 15 functions as a membrane bound cytokine that can only be present at the cell surface and support NK cell development when bound to IL-lSR ⁇ on the same cell (14, 15).
- the clear effect of ML-lSR ⁇ to enhance hIL-15 activity in vivo suggests this is also likely in man.
- the findings using a novel HIS- mouse approach demonstrate that hIL-15 trans-presentation is necessary to promote human NK cell development and differentiation in vivo.
- the failure to observe accumulation of CDIo + KIR + NK cells in HIS-mice with HSCs ectopically expressing Bcl-xL suggests that NK cell survival is alone not sufficient to promote differentiation and a source of human IL-15 is essential for this process.
- trans-presented IL- 15 induces KIR expression on CD56 l0 CDl ⁇ + NK cells in vivo and suggests that KTRs are expressed after CD 16 and that acquisition of KTRs represents a further step in NK cell differentiation.
- expression of human self-MHC-I on a fraction of the haematopoietic cells in HIS-mice appears sufficient in generating phenotypically mature KIR + NK cells.
- IL-15R agonists particular RLI in augmenting human NK cell development in HIS-mice will enable us to more readily dissect the role of IL- 15 dependent lymphocytes (NK cell, memory CD8 T cell, NK T cell and ⁇ / ⁇ T cell) responses to human pathogens and disease in vivo.
- IL- 15 dependent lymphocytes NK cell, memory CD8 T cell, NK T cell and ⁇ / ⁇ T cell
- Given obvious crosstalk between innate and adaptive immune cells having robust reconstitution of IL-15 -dependent cells in vivo improves the accuracy and application of HIS-mice for studying human immune responses.
- mice were maintained in isolators with autoclaved food and water. Mice with a human immune system (HIS) were generated as previously described [69-71]. Briefly, newborn (3 - 5 day old) Rag2 ⁇ /" ⁇ c ⁇ / ⁇ mice received sub-lethal (3.3 Gy) total body irradiation from a Cs source, and were injected intra-hepatic (i.h.) with 5xlO 4 sorted CD34 + CD38 ' human fetal liver cells. All manipulations of HIS mice were performed under laminar flow. Mouse experiments were approved by an institutional committee at the Institut Pasteur and validated by the French Ministry of Agriculture.
- HIS human immune system
- HIS mice were injected intra-peritoneally with lOO ⁇ l of 2.5 ⁇ g RLI or PBS alone commencing at a either 5-6 weeks after reconstitution or 8 weeks after reconstitution.
- lOO ⁇ l of lOmg/ml of BrdU from BrdU flow kit was injected IP daily 2 days prior to analysis.
- HIS mice were immunized by intramuscular route (biceps femoris) using a 29G needle, three times on weeks 12, 14 and 16 with 100 ⁇ l of the HBV vaccine (Engerix-B, Glaxo SmithKline). These amounts correspond to 1/10 of the normal human dose.
- Negative controls received the same volume of PBS buffer.
- Intracellular staining was performed after fixation and permeabilization of the cellular suspensions using BD Perm/Wash and BD Cytofix/Cytoperm reagents from BD Bioscience (San Jose, CA) according to manufacturer instruction.
- BrdU detection cells were incubated for 1 h at 37°C with 30 ⁇ g DNAse from BrdU flow kits (BD Bioscience, CA).

- CD34 Progenitor Cell Isolation Kit Miltenyi Biotech, Auburn, CA
- Single-cell suspension and isolation of mononuclear cells by density gradient centrifugation over Ficoll-Hypaque (Nycomed Pharma, Roskilde, Denmark).
- Cell suspensions were prepared in RPMI medium with 2% fetal calf serum.
- Single cell suspensions of murine organs were prepared as previously described [99].
- Thymocyte populations from HIS mice treated with PBS or RLI were electronically sorted using FACSARIA (BD Bioscience) and were cultured at 1 x 10 4 cells/ml in RPMI with 10% FCS or either lOng/ml rhIL-15 (rhIL-15; R&D Systems, Minneapolis, MN) or 10ng/ml rhIL-7 (Peprotech) for 30 hours. Viable cells were determined by PI exclusion using flow cytometry.
- TCR V ⁇ immunoscope was performed as previously described [100], Briefly, cDNA was prepared and real-time PCR performed by combining primers for the different V ⁇ chains (V ⁇ l-24, V ⁇ 2-9 and V ⁇ l-8). Fluorescent products were separated on ABI-Prism 3730 DNA analyzer to determine CDR3 lengths. Analysis of five individual HIS-mice from each group containing greater than 30% human chimerism in the spleen was performed. [098] Luminex® cytokine detection. Sera from HIS mice were prepared from total blood at time of sacrifice by centrifugation at 13,000 rpm for 10 minutes at 4 degrees. Cytokine human 25-plex panal Luminex ® assays were performed according to manufactures instructions (Invitrogen).
- ELISA The plasma harvested from HIS mice was screened by ELISA for the presence of antigen-specific and total antibodies. For this purpose, 96-well plates were coated either with Engerix B (glaxoSmithKline BV, Zeist) (1Ox diluted in PBS) or lO ⁇ g/ml goat anti-human IgM or 10 ⁇ g/ml goat anti-human IgG (Jackson ImmunoResearch Laboratories) in PBS for lhr at 37°C or o/n at 4 0 C. After coating, the plates were washed in PBS with 0.5% Tween-20.
- a PBS solution containing 4% of milk was used as a blocking agent, before serial dilution of HIS mouse plasma or cell culture supernatants.
- ELISA was revealed with horseradish peroxidase-labeled goat anti-human IgM and IgG antibodies (Jackson ImmunoResearch Laboratories) followed by TMB substrate/stop solution (Biosource, Carlsbad, CA, USA).
- HIS mice 8 weeks after HSC engraftment, HIS mice were injected intra-peritoneally weekly for 4 weeks with 2.5 ⁇ g of a potent human IL-15R agonist known as RLI consisting of human IL- 15 covalently linked to an extended human IL-15R ⁇ 'sushi' domain [66, 74, 75] and therefore capable of mimicking IL- 15 trans-presentation (Fig. 8A).

- Fig 9C KIR antibodies recognizing KIR2DL2/3/1, KIR2DS1/2/4 and KIR3DL1/S1
- Fig 9C A significant increase was observed in the percentage and total number of KIR + T cells, which included an expansion of T cells expressing either one or both of the KIR2DL2/3 and KIR3DL1 receptors.
- Other NK- associated cell surface markers such as CD 16 and CDl 61, but not CD 56 were also induced or up-regulated on T cells from all organs analyzed from IL-15 treated mice (Fig 9C).
- HIS mice receiving trans-presented human IL-IS show increased proliferation of peripheral human CD4 and CD8 T cells.
- the ratio of CD8 + to CD4 + T cells following IL- 15 treatment was only mildly increased in the spleen and unchanged in other lymphoid organs of recipient mice (Fig 9B).
- the clear augmentation in T cell numbers but no diminution in the relative size of the naive T cell pool compared to control mice indicates that IL-15 trans-presentation in vivo targets the expansion of both na ⁇ ve and activated T cells.
- humanized mice treated with RLI were injected IP with lO ⁇ g of BrdU 24 and 12 hours before being sacrificed and T cell populations analysed for BrdU incorporation.
- CD8 + and CD4 ⁇ na ⁇ ve (CD45RA + ) and activated (CD45RA " ) T cell proliferation in the spleen and mesenteric lymph node were significantly increased following IL- 15 trans- presentation in vivo (Fig 10A, B).
- CD8 + T cells, in particularly those with a na' ⁇ ve phenotype showed the greatest fold increase in proliferation in both the spleen and the mesenteric lymph node after IL- 15 treatment followed by na ⁇ ve CD4 + T cells, activated CD8 + T cells and lastly activated CD4 + T cells (Fig 10 A, B).
- IL-15 The efficiency of IL-15 treatment and relative responsiveness of T cell populations can be compared to that of NK cells who are highly dependent on IL-15 (Fig 10 A, B).
- Other ⁇ c cytokines such as IL-2 and IL-7 could also influence the observed increase in human T cells by inducing proliferation and enhancing survival.
- the serum concentration of these and other cytokines that are produced by IL- 15 responsive lymphocytes such as NK cells was not analysed.
- the serum concentration of IL-2 and IL-7 were unchanged in mice treated with trans-presented IL- 15 and were only slightly above the level of detection using Luminex bead array assays (Fig 10 C), with the IL-2 result being confirmed by intracellular staining of T cells from these mice showing no difference between treatment groups.
- Thymocyte turnover was analysed in the same manner as previously mentioned by injecting mice with lO ⁇ g of BrdU 24 and 12 hours before being sacrificed.
- thymic NK cell turnover is doubled following IL- 15 treatment in vivo
- SP4 and SP 8 T cell turnover is unchanged, which is in sharp contrast to what was observe in the periphery (Fig 11 B).
- the increase in DN and DP thymocytes likely arises from the significant increase (*P ⁇ 0.05) in proliferation of these two thymocyte populations in IL- 15 treated mice (Fig 11 B). While both the number and turnover of iSP4 thymocytes were always increased in. IL- 15 treated mice, this increase was not statistically significant.
- ⁇ SP4 thymocytes presented the highest rate of proliferation with around 75% of these cells dividing within 24 hours, thus if IL- 15 is capable of enhancing the division of this population it is less likely to be observed given the high baseline turnover.
- IL- 15 trans-presented IL-15 is functional on human DN and DP thymocytes, other parameters were next examined such as cell survival.
- IL-15 offered very little survival advantage to purified DN thymocytes compared to media or IL-7, whereas both SP4 and SP8 thymocyte populations displayed a clear increased survival when cultured in IL- 15 for 30 hours (Fig 11 D).
- DP thymocytes however only displayed improved survival when cultured in IL-7, but not IL- 15 (Fig 11 D).
- Fig 11 E an improved ex vivo survival of thymocyte populations sorted from IL- 15 treated humanized mice compared to those sorted from control mice was not observed (Fig 11 E) indicating that increased proliferation as opposed to improved survival is the major contributing factor for the increased number of immature thymocytes following this treatment regime.
- TCR T cell receptor repertoire
- the peripheral T cell pool generated in our model of humanized mice appears extremely diverse especially considering the limited number of peripheral T cells that are generated in this model. Indeed, T cells bearing TCRs from all V ⁇ family members with numerous CDR3 lengths used amongst each family member were detected (Fig 12 A, B). This is a valuable piece of data considering that the model of humanized mice is becoming more popular for the study of T cell immune responses and indicates at least that an extensive TCR repertoire exists and could react against a large number of peptide antigens. A similar diversity was observed in the CDR3 length amongst all V ⁇ chains used except for the occasional over-representation of clones within the V ⁇ l 1 and V ⁇ 7. This was not consistent observed in all mice following IL- 15 treatment and was far less evident amongst thymic T cells from the same mice (Fig 12 A, B).
- ⁇ / ⁇ T cell population was increased in frequency and number (P ⁇ 0.05; Fig 13 B), however this was inline with the general augmentation in total T cells and was much less impressive than the increase we previously reported for NK cells using a identical treatment regime [71] and indicates in the HIS model, ⁇ / ⁇ T cells are not more responsive to IL- 15 than ⁇ / ⁇ T cells.
- CDR3 immunoscope analysis of ⁇ and ⁇ variable chain genes was next used to identify all ⁇ and ⁇ usage in HIS mice (since monoclonal antibodies against each unique ⁇ and ⁇ are not commercially available). These type of analyses on spleen- derived human T cells were used as they are more numerous than those derived from LN in the HIS model. Consistent with the flow cytometry data, most human ⁇ / ⁇ T cells found in the periphery of HIS mice use V ⁇ 2 and this is similar to human PBMCs and unaffected by IL-15 treatment (Fig 13 C).
- Trans-presented human IL-15 accelerates T cell development in HIS mice. Since trans-presented IL- 15 was extremely efficient in increasing total human T cell numbers in HIS mice and displayed a clear effect in the thymus, it was next determined whether IL- 15 immunotherapy could promote early thymopoeisis, before mature T cells are generated, thus accelerating mature T cell production.
- thymus and spleen from HIS mice were analysed at various ages and it was found that between 5 - 6 weeks after HSC engraftment represented the ideal window to commence the IL- 15 immunotherapy as the thymus was seeded with immature thymocytes including DPs, DNs and iSP4s and almost no mature T cells, the latter also being the case for the spleen (Fig 14 A).
- HIS mice were then treated with a more intense IL- 15 treatment regime that entailed 2.5 ⁇ g of IL-15R agonist, IL-15+IL-15R ⁇ (RLI) every three days (day 0, 3, 6 and 9) and HIS mice were then sacrificed and analyzed on day 12.
- Thymus, spleen and BM from IL- 15 immunotherapy HIS mice and PBS controls were then analyzed for human chimerism (hCD45 + ) and mature T cell development (hCD45 + CD3 + ).
- IL- 15 trans-presentation resulted in significant increase in human T cells in all organs analysed, promoting both SP4 and SP 8 development in the thymus resulting in a significantly increased pool of na ⁇ ve mature T cells (hCD45 + CD45RA + CD3 + ; Fig 14 B).
- HIS mice models have been continually improved and are now at a stage where immune responses can be elicited by the engrafted human lymphoid system (reviewed in [77]). Indeed both antibody and cellular immune responses against vaccines such as tetanus toxoid and viruses such as Epstein Barr virus have been detected in various HIS models [78-80].
- IL- 15 can skew activated T cells towards a ThI phenotype as determined by an increased IFN- ⁇ /IL-4 protein ratio. Tehre was a failure to detect any difference in serum or intracellular IFN- ⁇ levels in CD4 + and CD 8* T cells of IL- 15 treated mice compared to controls. Furthermore, intracellular granzyme-B levels in CD4 + and CDS + T cells were also unchanged.
- IL- 15 induces anNK-like phenotype (with CD56 expression) on thymocytes or preferentially expands the existing CD56 + T cell pool [82-84]. It was shown that CD56 " T cells from PBMC do not proliferate to IL-15, whereas CD8 ⁇ and V ⁇ 24 + V ⁇ l I + robustly proliferated to IL-15 in vitro [82]. We failed to detect CD56 expression on T cells in HIS mice following treatment with trans-presented human IL- 15 treatment. In addition, ⁇ / ⁇ T cells were only increased to a similar level as ⁇ / ⁇ T cells, which is in contrast to data suggesting that human ⁇ / ⁇ T cells are more responsive on IL- 15 in vitro.
- IL-2 is a likely candidate as it is produced by antigen activated T cells and promotes T cell division. There was a failure to detect any difference in the serum level of IL-2 between treated and control mice, nor in the intracellular concentration of IL-2 in T cells from both groups of mice. While human IL-15 is functional on mouse hematopoeitic cells, HIS mice lack their endogenous ⁇ c receptor, thus all of the observed effects involve IL- 15 receptor triggering on human cells.
- trans-presented IL-15 to promote human thymopoeisis offers a unique new therapeutic approach to augment human T cell numbers during immunotherapy to cancer or to reduce the period of immunodeficiency following radiotherapy/chemotherapy and HSC transplant by promoting NK and T lymphopoeisis. It has been previously shown that trans-presented IL- 15 (RLI) is effective in an NK cell-dependent murine metastatic melanoma and colorectal cancer model [86], while others have reported similar effects with CD8 + T cell-dependent systems [87, 88].
- IL-15 has been shown to induce antigen independent expansion of na ⁇ ve, virus specific and tumor specific cytotoxic CD8 + T cells in vitro [74, 89-92] and rescue tolerant CD8 + T cells for use in adoptive immunotherapy of established tumors [93].
- IL-15 has been shown to be more potent than IL-2 in inhibiting apoptosis of memory CD4 + T cells in vitro as well as of na ⁇ ve phenotype CD4 + T cells from HIV infected individuals in both examples by up-regulating Bcl-2 [94-96].
- IL-15 has also been shown to enhance number, function and survival of HTV- specific CD8 + T cells [97,98] indicating that trans-presented IL-15 treatment could improve the clinical condition of diverse disease states by not only boosting T cell numbers but by augmenting antigen specific T cell responses.
- the findings using human immune system mice demonstrates that human IL-15 trans-presentation is effective in promoting human T cell development and homeostasis in vivo and in the absence of any obvious toxicity.
- IL- 15 boosted HIS mice provide an improved humanized mouse model for evaluating pre-clinical immunotherapies and for deriving and screening novel immunomodulatory drugs.

Abstract
La présente invention concerne un système de modèle d'animal transgénique, fondé sur le développement de souris transgéniques portant des composants du système immunitaire humain, comprenant un grand nombre de lymphocytes innés tels que des cellules tueuses naturelles (NK) humaines matures, des cellules T γδ et des cellules NK-T, ainsi que des lymphocytes T CD4 et CD8 adaptatifs. L'invention concerne de plus l'utilisation dudit système de modèle pour évaluer, ou pour identifier, des composés qui modulent (inhibent ou activent) l'activité ou la maturation de lymphocytes humains innés, tels que des cellules tueuses naturelles (NK) humaines matures, des cellules T γδ, et des cellules NK-T, ainsi que de lymphocytes T CD4 et CD8 adaptatifs. Ces composés peuvent être utilisés dans des immunothérapies pour le traitement de maladies pathogènes, du cancer, de maladies auto-immunes, infectieuses et inflammatoires, de l'immunodéficience, et pour le traitement de patients ayant subi une greffe. La présente invention est fondée sur la découverte du fait que la différenciation et l'expression de cellules tueuses naturelles de récepteurs d'inhibiteur du type tueur (KIR), ainsi que l'homéostasie et le développement de cellules T CD4 et CD8 humaines adaptatives, sont régulés par la transduction de signal à médiation par IL-15.
