NFKB1 and rheumatoid arthritis: A study (48) showed that quercetin could inhibit RANKL production and monocyte-to-osteoclast formation in IL-17-stimulated RA-FLS, inhibit Th17 differentiation and IL-17 secretion, and exert immunomodulatory effects in IL-17-stimulated RA-FLS through mTOR, ERK and NF-κB pathways.
