Potential involvement of IL-9 and Th9 cells in the pathogenesis of rheumatoid arthritis

2015

Objective IL-9 has been shown to be upregulated before the clinical onset of articular disease in RA. The exact role of IL-9 and Th9 cells in RA, however, has not yet been adequately studied. The aim of this study was to evaluate the expression of IL-9 and IL-9-expressing cells in RA patients. Methods IL-9, IL-9R, PU.1, IL-9, thymic stromal lymphopoietin (TSLP), IL-4 and TGF-β expression was assessed by real-time-PCR in the synovial tissues of RA and OA patients. IL-9, IL-9R, IL-4, TSLP and TGF-β were also investigated by immunohistochemistry. Peripheral CD4(+) T cell subsets were studied by flow cytometry analysis before and after incubation with citrullinated peptides. Results IL-9 was ov…

The in vitro addition of methotrexate and/or methylprednisolone determines peripheral reduction in Th17 and expansion of conventional Treg and of IL-…

2014

The aim of our study was to evaluate methotrexate (MTX) and methylprednisolone (MP) effect on peripheral Th17 and Treg subsets in patients with rheumatoid arthritis (RA). We enrolled 15 patients (10 early RA and 5 long-standing disease) with active RA and 10 age-matched healthy donors as controls. Frequencies of Th17 and Treg were quantified using flow cytometry before and after in vitro addition of MTX, MP or both drugs. Our results showed a reduction in the overall Th17 population followed by an increase in Th17 IL-10+ and Treg, after in vitro treatment of PBMCs with the drugs in patients with early RA. Long-standing disease patients showed a less evident increase in Treg cells and less e…
