Quercetin also has been reported to improve diabetes-related complications in in vivo mouse and rat studies by interfering with the innate signaling pathways such as TLRs and peroxisome proliferator-activated receptor ɣ (PPARɣ) and inhibiting the activity of nuclear factor κ light-chain enhancer of activated B cells (NF-κB) which subsequently reduces the levels of TNF and CRP (94–96). The gene discussed is CRP; the disease is diabetes mellitus.
