title: Antithymocyte globulin combined with cyclosporine A down-regulates T helper 1 cells by modulating T cell immune response cDNA 7 in aplastic anemia.
abstract: Antithymocyte globulin (ATG) combined with cyclosporine A (CsA) has been widely used as a standard regimen in the treatment of aplastic anemia (AA), especially in severe aplastic anemia (SAA). Abnormally activated T cells might be the immune pathogenesis of AA. T cell immune response cDNA 7 (TIRC7) has been demonstrated its essential role in T cell activation; however, little is known about the role of TIRC7 in AA. In this study, we documented that TIRC7 levels in CsA group were higher than that in ATG + CsA (AC) group only in the follow-up phase (P < 0.05; P < 0.05); nevertheless, TIRC7 levels in SAA group were elevated than non severe aplastic anemia group not only in the treatment phase (P < 0.05; P < 0.05) but also in the follow-up phase (P < 0.05; P < 0.01). The trend of changes of T helper (Th) 1, Th17 and Th22 levels before and after treatment was similar to the changes of TIRC7 levels in either AC group or CsA group. Thus, TIRC7 might be involved in the pathogenesis of AA and AC might down-regulate Th1 cells by modulating the expression of TIRC7 in AA.
