TGFB1 and tauopathy: mRNA expression levels of selected genes of complement system (C1QL1, C1QTNF7, C3AR1), colony stimulation factors (CSF1R, CSF3R), Toll-like receptors (TLR4, TLR7), IL8, pro-inflammatory cytokines (IL6, IL6ST, IL1B), TNF-α family (TNFRS1A, TNF-α), IL-10 family (IL10, IL10RA, IL10RB), and TGF-β family (TGFB1, TGFB2) were analysed in 20 middle-aged individuals with no neuropathological lesions, 58 age-matched controls, 105 cases of sporadic AD, 56 cases of sporadic PD, 30 cases of sCJD (15 MM1 and 15 VV2), and 18 tauopathies.
