Receptor activator of nuclear aspect B ligand, a member of tumor necrosis aspect a, is produced by osteoblasts and stimulates its receptor RANK on osteoclast progenitors to differentiate them to osteoclasts. WP9QY peptide designed to mimics TNF receptors contact site to TNF a was known to abrogate osteoclastogenesis in vitro by blocking RANKL RANK signaling. WP9QY ameliorated collagen induced arthritis and osteoporosis in mouse models. Here we report that the peptide surprisingly exhibited bone anabolic effect in vitro and in vivo. WP9QY was administered subcutaneously to mice three times per day for 5 days at a dose of 10 mg/kg in normal mice, followed by peripheral quantitative computed tomography and histomorphometrical analyses.
Interaction between cell kinds and phenotypes hts screening should be confirmed like a future program.

P19 Balb/c FasKO mice create allergic blepharitis connected with hyper production of IgE Ayumi Fukuoka1, Shizue Yumikura Futatsugi2, Suzuka Takahashi1,three, Hirotaka Kazama1, Kenji Nakanishi2, Shin Yonehara1 one Immunology kinase inhibitor and Health care Zoology, Hyogo College of Medicine, Japan, 3Institute of Genome Reserch, The University of Tokushima, Japan Arthritis Investigation & Therapy 2012, 14 19 Fas is a member of the TNF receptor family and crucial for induction of apoptosis. MRL lpr/lpr mice, which carry a mutation of Fas, spontaneously produce systemic autoimmune disease including arthropathy, indicating that Fas plays an important role in elimination of self reactive immunocytes by apoptosis. In addition to autoimmune diseases, we found a novel phenotype of FasKO mice exclusively in Balb/c genetic background that is allergic blepharitis. Allergic blepharitis is revealed in Balb/c FasKO mice from 15 week old and about 85% of the mice suffered from allergic blepharitis at 35 week old.

Serum concentrations of both IgG1 and IgE Abs were about 100 times higher in 20 week old FasKO mice than in Cholangiocarcinoma WT mice, however, there was no significant difference amongst WT and FasKO mice within the ability of B cells to produce IgG1 and IgE Abs inside the presence of IL 4 and anti CD40 Ab inducing co stimulatory signals. Additionally, the production of IL 4 by T cells was same. enhanced IgG1 and IgE Abs production from B cells in Balb/c FasKO mice. To identify the cells enhancing IgG1 and IgE Abs manufacturing, we cultured B cells in vitro from the presence of IL 4 and anti CD40 Ab together with various varieties of cells from Balb/c FasKO mice. In the result, we found FasKO non T non B cells upregulated the production of both IgG1 and IgE from B cells.

Moreover, the number of these cells was specifically increased in Balb/c FasKO PI3K-PDK1 mice. All the results indicate that these cells enhance production of IgG1 and IgE from B cells in the presence of IL 4 and anti CD40 Ab, and excessive accumulation of these cells may cause allergy via hyper production of IgE.
