    摘要

    Starting from the classical Th1/Th2 paradigm, we aimed at refining our understanding of the role of T helper cell subtypes in rheumatoid arthritis (RA) and in the response to anti-tumour necrosis factor (TNF) therapy. Although the main localization of inflammation lies undoubtedly in the joint, activated non-regulatory T helper cells are present in the peripheral circulation. Anti-TNF therapy enhances the production of the prototypical Th1 cytokine interferon (IFN)-gamma by these T cells. This effect is not mediated via the TNF signalling pathway through the activation of p38 mitogen-activated protein kinase (MAPK), but via activation of the signal transducer and activator of transcription (STAT)-4 pathway, which is specifically responsible for Th1 differentiation and cytokine production. Despite its therapeutic success, anti-TNF therapy induces not only an increase in peripheral IFNgamma-producing Th1 cells, but also in interleukin (IL)-17-producing Th17 cells, both of which have pro-inflammatory potential. However, the increase in peripheral Th17 cells is accompanied by a decrease in Th17-specific CC-motif chemokine receptor (CCR)-6 expression, possibly preventing homing to the synovium. These findings stress the ambivalence of primarily pro-inflammatory cytokines such as TNF and IFNgamma, the complexity of regulatory feedback mechanisms and the spatial organization of the immune response, all of which have to be considered in the development of future therapeutic strategies.
