Rheumatoid arthritis (RA) is a disease with significant gender differences in its prevalence and clinical features. Interleukin (IL)-1 and tumor necrosis factor (TNF) α produced by synoviocytes are principle inflammatory and destructive mediators of RA. We found that a potent androgen, 5α-dihydrotestosterone (DHT) inhibits IL-1α-induced production and mRNA expression of IL-8, IL-6 and IL-1β from RA patient-derived fibroblast-like synovial cell line MH7A. Promoter analysis of the IL-8 gene… CONTINUE READING
