Impaired TGF-beta responses in peripheral T cells of G alpha i2-/- mice.

Abstract excerpt

Null mutation of heterotrimeric G protein alpha2 inhibitory subunit (Galphai2) induces Th1-skewed hyperimmune responses in the colon, leading to chronic colitis and the development of colonic adenocarcinoma. However, the underlying molecular mechanisms and cellular basis, in particular, for the role of Galphai2 in regulating immune responses, are poorly understood. We show here that peripheral T cells from...
