immune system
abnormal CD4-positive T cell differentiation ( J:132905 )
• IL-17 producing CD4+ T cells differentiated in vitro and induced with IL-6 and TGF-beta with the anti-TCR antibody results in stronger induction of IFN-gamma producing cells and a marked reduction of IL-17 producing cells in contrast to similarly treated wild-type cells
• CD4+ T cells preferentially differentiate into Th1 cells and not Th17 unlike wild-type cells
abnormal CD4-positive, alpha-beta T cell physiology ( J:132905 )
• CD4+ T cells are resistant to the suppressive effects of TGF-beta on IGN-gamma production unlike wild-type cells
decreased susceptibility to experimental autoimmune encephalomyelitis ( J:132905 )
• mice are less susceptible to experimental autoimmune encephalomyelitis (EAE) and produce less IL-17 following EAE compared to wild-type mice
