Fetal fibroblasts and spleen cells were collected from the prepared ASK1 knockout mice, and the amounts of production of IL-1, IL-6 and MIP-1 ⁇ induced by LPS (lipopolysaccharide) stimulation were measured. As a result, fetal fibroblasts and spleen cells of ASK1 knockout mice were significantly different from those of wild type (normal) mouse fetal fibroblasts and spleen cells. The production of spikes was suppressed. From these facts, it was revealed that reducing the activity of ASK1 can actually suppress the production of the cytokine ⁇ chemokine. Therefore, the above experimental results indicate that ASK1 inhibitors are extremely useful for prevention and treatment of various immune diseases.
- the present inventors have found that in an in vivo test using a sepsis model, the survival rate of ASK1 knockout mice is significantly improved as compared with wild-type mice, and that the ASK1 knockout mice Observed that there was little increase in blood TNF concentration. From these facts, it was found that reducing the activity of ASK1 can remarkably improve the pathology of various immune diseases such as sepsis.

- the target function was amplified and detected by the following method. First, an adenovirus vector (Ad-ASK1- ⁇ ) incorporating this active ASK1 was prepared, and the active human ASK1 was overexpressed in cultured normal human skin keratinocytes by the adenovirus method.
- the recombinant virus is infected with 3 x 10 6 eel 1 s / we 11 normal human cultured skin keratinocytes at an efficiency of about 5 and the cells and culture supernatant 5 mL was collected.
- the increase in mRNA expression levels of various cytokins and chemokines was quantified using the RNase protection assay, and the protein concentration released into the culture supernatant as the actual protein expression level was determined by ELISA. It was quantified using.
- untreated cells and cells expressing) 3-galactosidase instead of active ASK1 were compared.
- GAPDH a gene whose mRNA level did not change with stimulation, was used as a negative control.
- Fig. 1 For the mRNA expression levels of various cytokines and chemokines, and for the protein expression levels in Fig. 2 (IL-18), Fig. 3 (MIP-la), and Fig. 3 respectively. This is shown in Fig. 4 ( ⁇ ⁇ ⁇ _1; 3) and Fig. 5 ( ⁇ ⁇ ⁇ —3a).
- ASK1 activation of ASK1 causes cytokines such as IL-1 and IL-1 / 3, as well as IL-8, ⁇ ⁇ ⁇ _1 (3 ⁇ 4, ⁇ ⁇ ⁇ — 1/3, MI ⁇ -3 This indicates that the expression of mRNA or various proteins of chemokines such as a is induced.
- chromosomal DNA fragments including the first exon of ASK1 were cloned from the chromosome (genomic) DNA library of 129ZS VJ mice (Strategene). Using one of the clones, 10 kb upstream and 2 kb downstream of the first exon were used as the homologous recombination region, and the first exon and the adjacent intron region were converted to GFP (greenflourescence protein) and neomycin for positive selection. A targeting vector replaced with a resistance gene was constructed. As a targeting vector, pBluescript SK (Strategene) containing DT-A (diphtheria toxin ⁇ chain) for negative selection was used.
- GFP greenflourescence protein
- the evening vector was introduced into J1 ES cells (embryon icst emce11) by the electoporation method. After selecting neomycin-resistant ES cell colonies, homologous recombination cells were further confirmed by Southern blotting. Heterozygous mutant ES cells were introduced into C57BL / 6J blastocysts by microinjection. Backcrossing of the born chimeric mice to C57BLZ6J mice resulted in F1 (first generation) heterozygous mice. After confirming whether or not the gene mutation was introduced into germ cells by Southern blotting, ASK1 knockout mice, which are homozygotes of ASK1, were established from the crossing of these F1 heterozygous mice. . Test example 3
- Inflammatory cytokine IL-1 ⁇ stimulated by LPS using fetal fibroblasts (mouse embryon icfibrob 1 asts; ME F s) and spleen cells (sp 1 e no cytes) from ASK 1 knockout mice Then, it was examined whether ASK1 is involved in the induction of the expression of IL-16 and the chemokine MI ⁇ -1 ⁇ .
- fetal fibroblasts MEFs
- 10 g / mL LPS was added to cells seeded at a concentration of 1 ⁇ 10 5 ce 11 s / we 11
- the temporal change in the secretion amount of IL-16 protein into the culture supernatant at 12, 24 hours was measured.
- ILs were added to cells seeded at a concentration of 1 ⁇ 10 5 ce 11 s Zwe 11 by adding 10 Z gZmL of LPS to about 0.5 mL of medium.
- 1) Induce the expression of 3, IL-6 and MIP-1 ⁇ , and 1-1,3, IL-6 and MIP in the culture supernatant at 6, 12, and 24 hours after LPS stimulation. -The amount of secreted protein was measured.
- the expression levels of each of the cytokines and chemokines were determined using the ELISA method, as in Test Example 1.
- Figures 6 and 7 show the results for fetal fibroblasts (MEFs), and Figures 8, 9 and 10 show the results for spleen cells (sple no cytes).
- MEFs fetal fibroblasts
- Figures 8, 9 and 10 show the results for spleen cells (sple no cytes).
- spleen cells derived from ASK1 knockout mice splenenocytes
- IL-13 Fig. 8
- IL-6 Fig. 9
- MIP-1 ⁇ Fig. 10
- the survival rates of the ASK1 knockout mouse and the wild-type mouse in the sepsis model were compared. Sepsis was induced by injecting LPS into mice intraperitoneally at a dose of 18.7 mg Zkg body weight. In sepsis, a sharp rise in cytokines has been observed, which has been shown to cause subsequent shock death. Therefore, the TNF- ⁇ concentration in the blood 2 hours after the induction was measured, and thereafter the survival rate of the individual was observed over time. In addition, 10 knockout mice and 10 wild-type mice were used.
- FIG. 11 shows the change over time in the survival rate of the individual
- FIG. 12 shows the TNF- ⁇ concentration in the blood 2 hours after the induction in the ASK1 knockout mouse and the wild type mouse, respectively.
- FIG. 12 shows the survival rate in the ASK1 knockout mice.
- the present invention relates to the prevention or treatment of an immune disease using an ASK1 inhibitor as an active ingredient.
- various immune diseases such as rheumatoid arthritis, type I diabetes, systemic lupus erythematosus, psoriasis, inflammatory bowel disease, multiple sclerosis, thrombocytopenia, siedalen syndrome, bronchial asthma, atopic dermatitis, and sepsis Of the present invention can be provided.
