| Zusammenfassung: | Copyright © 2017 Elsevier Inc. All rights reserved. The IL-17/1L-23 axis is important in the pathogenesis of spondyloarthropathy. Innate cells produce IL-17 in addition to Th17 cells. We studied the frequencies of natural killer (NK) (total, CD56bright, CD56dim, perforin+ and granzyme+), NK-T, γδ-T, and IFN-γ+, IL-17+ NK and γδ-T cells in peripheral blood (PB) and synovial fluid (SF) of ReA/uSpA patients. PB from 45 patients and paired SF from 39 patients were studied, together with PB from 18 healthy controls (HC). The frequency of γδ-T cells was decreased (p<0.05) while IL-17 producing NK and γδ-T cells were increased (p<0.05) in PB of patients as compared to HC. In SF, CD56bright NK cells were increased (p<0.001) but had reduced expression of perforin and granzyme (p<0.0001) as compared to PB. Frequency of IL-17+, IFN-γ+ NK and γδ-T cells was higher in SF as compared to PB (p<0.05). We suggest that innate cells by producing pro-inflammatory cytokines may contribute to pathogenesis |
