TLR2 and Autoimmunity: Despite the lack of evidence, the potential effect of resveratrol on inflammatory markers should not be rejected, as a recent study by Yuan et al. [149] reported the beneficial effects of resveratrol on oxidative stress and inflammation in granulosa cells from PCOS patients (downregulation of TNF-α, IL-1β, IL-6, and IL-8) due to the inhibitory effect on toll-like receptor 2 (TLR2) [149], which is involved with immune cell activation in relation to infections and autoimmunity (reviewed by Marks et al. [150]).
