In AIH, Gal9(pos) T-regs were fewer and contained less FOXP3(pos), IL-10(pos), and transforming growth factor β(pos) and more IFNγ(pos) and IL-17(pos) cells than HS. siRNA treatment of Gal-9(pos) T-regs drastically reduced T-reg ability to suppress CD4(pos) CD25(neg) and Tim-3(pos) cell proliferation in AIH and HS.
We hypothesized that, anti-CD200 inhibited the phosphorylation of SHIP1, the expression of T-bet, GATA3 and FoxP3 mRNA and CD4<sup>+</sup> T differentiation to protect the liver from autoimmune hepatitis.
