IL6 and Alzheimer disease: Pre-treatment of the cells with 1.5 mM of quercetin significantly reduced the expression of AD-induced IL-1b, IL-6, IL-8, and thymic stromal lymphopoietin (TSLP), while it strongly enhanced the expression of superoxide dismutase-1 (SOD1), SOD2, catalase, glutathione peroxidase, and IL-10 [53].
