a–f Immunohistochemical staining of BM samples obtained from patients with RA (n = 6) and OA (n = 6); EnVision stain, ×200. a, b CD4+ T cells in lymphoid follicle. c, d CD8+ T cells in lymphoid follicle. e, f IL-17A expression in lymphocytes in lymphoid follicle. g Concentration of IL-17AF in OA and RA BM plasma (OA n = 32; RA n = 28) and in OA and RA blood plasma (OA n = 21; RA n = 15). h Concentration of IL-17FF in OA and RA BM plasma (OA n = 34; RA n = 28) and in OA and RA blood plasma (OA n = 23; RA n = 15). Differences between groups were calculated using Mann–Whitney U test. BM bone marrow, IL interleukin, OA osteoarthritis, PB peripheral blood, RA rheumatoid arthritis
