PG - 6807 LID - 10.1038/s41598-017-07316-3 [doi] LID - 6807 AB - Toll-like receptor 2 (TLR2) mediates the innate immune response to bacterial lipopeptides and peptidoglycans by stimulating the production of inflammatory cytokines. However, the mechanisms by which TLR2 signaling regulates type I interferon (IFN)-beta production are poorly understood. Here, we identified Src homology 2-containing protein tyrosine phosphatase 2 (SHP2) as a negative regulator of TLR2-induced IFN-beta production. Pharmacological inhibition or reduced expression of SHP2 potentiated TLR2 agonist-mediated IFN-beta transcription and STAT1 activation, whereas overexpression of SHP2 impaired IFN-beta transcription and STAT1 activation. SHP2 physically associated with the glycogen synthase kinase 3beta (Gsk3beta) in an agonist-dependent manner. Gsk3beta positively regulates transcription of IFN-beta following TLR2 stimulation by inhibiting the phosphorylation of SHP2. SHP2 inhibited the transcriptional activity of IRF-1 and IRF-8 at the IFN-beta promoter. Remarkably, IRF-1 and IRF-8 are recruited to the IFN-beta promoter in a SHP2 phosphatase activity-dependent manner. These findings provide insight into the mechanisms by which SHP2 and Gsk3beta work together to modulate TLR2-mediated IFN-beta production in macrophages.
