Activation of STAT6 by STING Is Critical for Antiviral Innate Immunity


ABSTRACT: Analysis of the transcriptional response of HEK293 or HEK293-STAT6 stable cell lines to poly(I:C) transfection. The hypothesis tested was that poly(I:C) transfection is capable of inducing the expression of STAT6-dependent antiviral genes. mRNA isolated from HEK293 or HEK293-STAT6 stable cell lines with control treatment or poly(I:C) transfection for 16 hours.

STAT6 plays a prominent role in adaptive immunity by transducing signals from extracellular cytokines. We now show that STAT6 is required for innate immune signaling in response to virus infection. Viruses or cytoplasmic nucleic acids trigger STING (also named MITA/ERIS) to recruit STAT6 to the endoplasmic reticulum, leading to STAT6 phosphorylation on Ser(407) by TBK1 and Tyr(641), independent of JAKs. Phosphorylated STAT6 then dimerizes and translocates to the nucleus to induce specific target  ...[more]
