Regulating Blimp-1 in TH2 cells
The transcription factor Blimp-1 has been reported to limit autoimmunity in T cells. Now, Poholek et al. explore the mechanisms regulating Blimp-1 expression in T helper 2 (TH2) cells. They found that the cytokine interleukin-10 (IL-10) induced Blimp-1 expression in TH2 cells through STAT3. Signal transducer and activator of transcription 3 (STAT3) and Blimp-1 then acted together to boost IL-10 expression in a positive regulatory loop. The induced Blimp-1 then limited cell expansion by inhibiting STAT5 induction of cell cycle and antiapoptotic genes. Thus, by activating Blimp-1, IL-10 may prevent cell expansion, thus restraining autoimmunity.
