V 3+CD4+ T Selective Expansion of TCR V 3+CD4+ T Cells in Collagen-induced Arthritis in DBA/1 Mice Jae Seon Lee, Mi La Cho, Jung Eun Lee, So Youn Min, Chong Hyeon Yoon, Wan Uk Kim, Jun Ki Min, Sung Hwan Park and Ho Youn Kim Rheumatism Research Center, Catholic Institutes of Medical Science, The Catholic University of Korea, Seoul, Korea ABSTRACT Background: Collagen-induced arthritis (CIA) in mice is animal model of autoimmune disease known as rheumatic arthritis in human. We investigated -specific CD4+ T cell receptor usage in CIA mice. Methods: In CIA model, draining lymph node (dln) CD4+ T cells and splenocytes at 3 rd, 5 th, 8 th week, we investigated -specific T cell proliferation, production of IL-17, IFN-, TNF-, IL-4 and IL-1. And we also performed anti- IgG Ab measurements in serum level, TCRV usage and T cell clonality with RT-PCR-SSCP analysis. Also, we performed proliferative response against when -specific T cell subset is deleted. Results: CIA mice showed more increase in the serum level of anti- IgG than normal mice after induction of arthritis. And the level of anti- IgG2a in CIA mice was increased after 3 rd week after primary immunization, while anti- IgG1 was decreased. Draining LN CD4+T cells have proliferated against stimulation at 3 rd week after 1 st immunization. CD4+T cells derived from dln of CIA mice produced proinflammatory cytokine IFN-, IL-17 etc. Draining LN CD4 T cells of CIA presented higher proportion of CD4+V 3+subsets compared to those of normal mice at 3 rd week after 1 st immunization, and they were increased in proportion by stimulation. Draining LN CD4+ T cells without TCRV 3+/V 8.1/8.2+/V 1b+cells were not responsive against stimulation. But, -reactive response of TCRV 3-/V 8.1/8.2-/V 1b- T cells was recovered when V 3+ T cells were added in culture. Conclusion: Our results indicate that CD4 +V 3+ T cells cells are selectively expanded in dln of CIA mice, and their recovery upon re-stimulation in vitro, as well as the production Th1-type cytokines, may play pivotal role in CIA pathogenesis.
