Definitions
- NK cells and lymphokine-activated killer (LAK) cells have been implicated in immunosurveillance against tumor cells and allograft rejection (T. Barlozzari, C.W. Reynolds, and R.B. Herberman, J. Immunol., 131. 1024, 1983; A.A. Rayner, E.A. Grimm, M.T. Lotze, E.W. Chu, and S.A. Rosenberg, Cancer. 55, 1327, 1985).
- NK Natural killer
- LAK lymphokine-activated killer
- Monocytes have also been removed by their adherence to nylon-wool columns or by centrifugal elutriation in order to generate LAK cells at high cell density. However, these procedures for monocyte removal are tedious and complicated. Some LAK cell precursors may also adhere to the nylon-wool columns. Therefore, we have employed PME, at a concentration of about 1 to 5 M, as a single step for monocyte depletion. We were able to generate LAK from PME-treated cells.
- the amino acid analogs can be used to protect against loss of NK activity not only in PBMC but also in peripheral blood lymphocytes (PBL) derived therefrom, e.g., by treatment of PBMC with nylon wool or centrifugal elutriation to deplete monocytes.
- PBL peripheral blood lymphocytes
- our invention is a method of generating LAK cell activity in peripheral blood ononuclear cells (PBMC) or peripheral blood lymphocytes (PBL) derived therefrom while retaining natural killer (NK) cell activity which comprises:
- this invention is a method of depleting monocytes from peripheral blood mononuclear cells (PBMC) while retaining natural killer (NK) cell activity in the cells which comprises treating the PBMC with (a) a lower alkyl ester of an amino acid or dipeptide or an amide of an amino acid as defined above, or a pharmaceutically acceptable salt of said ester or amide, and (b) a member of the group consisting of benzamidine and phenyalaninol.
- PBMC peripheral blood mononuclear cells
- NK natural killer
- the invention is a method of inhibiting monocyte depletion and loss of NK activity upon treating PBMC with a lower alkyl ester of an amino acid or dipeptide or an amide of an amino acid as defined above, or a pharmaceutically acceptable salt of said ester or amide, which comprises simultaneously treating the cells with leucinol.
- PBMC for use in the invention can be obtained by Ficoll-Hypaque density gradient separation as described in the above applications or without Ficoll-Hypaque separation, as disclosed in 4,808,151, issued February 28,1989, the disclosure of which is also incorporated herein.
- the PBMC are washed, optionally treated by conventional techniques to deplete monocytes, as described in the incorporated applications, and suspended in suitable medium at a concentration in the range of about lxlO 6 to 2xl0 7 cells per mL.
- the dipeptides are disclosed in Lipsky and Thiele U.S. patent 4,752,602, the disclosure of which is also incorporated herein.
- Pharmaceutically acceptable salts of the esters and amides can also be used; preferred salts are the hydrogen chloride and hydrogen bromide salts.
- the suspension of PBMC or PBL is then cultured for an incubation period of about 2 to 7 days at 35 to 39°C, preferably 37°C, in presence of about 4-7% CO2. Culturing is carried out at a cell concentration in the range of about lxlO 6 to 2x10?, preferably 5xl0 6 to lxlO 7 cells per L, in medium containing IL-2 in concentration of about 150 to 1500 pM, preferably 1000-2000 pM.
- Culturing can be performed in conventional containers, such as T-flasks, but is preferably performed in closed, gas permeable sterile bags such as Du Pont's SteriCellTM cell culture bags. Culturing under these conditions generates LAK cells, a population of cells which are able to lyse tumor cells which are resistant to lysis by NK cells.
- LAK cells prepared by this invention are used in adoptive immunotherapy in the manner described in the incorporated applications 87107755.8 and U.S. application 07/038361.
- a 4 hour 51 lCr release assay was used to measure cytotoxicity of LAK cells for tumor cells.
- Tumor cells at a concentration of about 2xl0 6 to lOxlO 6 were incubated with 50 Ci of Na2 51 C > in 0.4 mL of Tris-phosphate buffered saline for 1 hour at 37°C.
- the cells are washed 4 times with RPMI 1640 containing 5% or 10% fetal calf serum (FCS) and resuspended to 10 5 cells/mL in cRPMI-20% FCS or RPMI 10% FCS.
- FCS fetal calf serum
- the effector cells (LAK cells) are suspended to various concentrations and 0.1 L is added to wells in round bottom microliter plates.
- the 51 Cr labelled target cells (0.1 mL) are added to all wells and the plates are centrifuged at 200 xg for 5 minutes. After 4 hours of incubation at 37°C, the plates are centrifuged again and 0.1 mL of resulting supernatant is removed from each well and counted in a gamma counter. Percent cytotoxicity is calculated from the following formula:
- % cytotoxicity experimental cp - spontaneous com x 100 total cpm - spontaneous cpm Each variable is tested in triplicate and the resulting data is expressed as % cytotoxicity or lysis. This cytotoxicity test is further described in "Selected Methods in Cellular Immunology", Mishell and Shiigi, eds., 124-137, W. H. Freeman and Co., San Francisco (1980).
- Example 1 We have studied the effect of PheOH and benzamidine on monocyte depletion, NK activity, and LAK activation by IL-2 of PBMC treated with PME.
- PBMC were treated with 5 mM PME in the presence or absence of PheOH and benzamidine.
- the PME-treated PBMC were analyzed for the % of monocytes by Giemsa staining and NK activity against K562 target cells, and were then cultured at lxl0 7 /mL with media containing rIL-2 for 3-4 days. LAK cell activity was then measured against 51 Cr-labeled Raji target cells.
- Example 2 PBMC were treated with 5 mM PME or 5 mM LME in the presence or absence of 5 mM LeuOH or PheOH.
- PME or LME was able to deplete monocytes. LeuOH was able to prevent the monocyte depletion by PME or LME.
- PheOH did not prevent the monocyte depletion by PME or LME.
- PME had little effect on the large granular lymphocytes (LGL) as measured by fluorescence activated cell sort (FACS) analysis, but inhibited NK activity against K562.
- LME depleted LGL and NK activity are shown in Table 2.
- LeuOH prevented the inhibitory actions of LME on LGL and NK activity. PheOH could prevent the inhibitory effects on NK activity by PME, but only partially prevented the inhibitory effects on NK activity by LME. LeuOH and PheOH had little adverse effect on enhanced LAK activation by PME. Moreover, LeuOH and PheOH reversed the inhibitory effect of LME on LAK activation.
- NK cells were assessed by FACS using Leul9 antibody against NK cells.
- NK activity was determined on Day 0 at an E:T ratio of 50:1 using K562 targets. Numbers are % lysis.
- LAK activity was assessed at a E:T ratio of 20:1 against Raji target cells, after cells were incubated at lxl0 7 cells/mL with 10 U/mL rIL-2 for 3 days. Numbers are % lysis.
