SHIP modulates immune receptor responses by regulating membrane association of Btk.

abstract：:The molecular basis of T cell anergy is not completely understood. We show that in antigen-primed anergic murine CD4(+) T cells the linker for activation of T cells (LAT) is hypophosphorylated upon CD3/CD28 restimulation. Signaling events downstream of LAT (PLCgamma1 phosphorylation and p85 [PI3-K] association) were i...

abstract：:Eradication of a given pathogen is dependent on the selective differentiation of T helper (Th) cells into Th1 or Th2 types. We show here that T cells from mice lacking the transcription factor IRF-1 fail to mount Th1 responses and instead exclusively undergo Th2 differentiation in vitro. Compromised Th1 differentiatio...
