In murine glioma models, TLR2 is selectively upregulated in glioma-associated microglia. We found that TLR2 activation led to down-regulation of MHC-II in microglia. Therefore, we examined the effect of TLR2 activation on IFN-gamma-induced microglial transcriptome by in vitro culture of murine adult microglia. In the study, we confirmed that TLR2 activation led to Ciita shutdown and inhibition of MHC-II related genes, which also revealed the role of TLR2 in inducing APC disability and tumor immune escape. In addition, this work can be used to reveal the transcriptional characteristics of murine microglia during IFN-gamma and TLR2 activation.
