OBJECTIVE: The aim of this study was to investigate the turnover of Treg cells in the SF of RA patients. METHODS: Treg cells were enumerated in peripheral blood and SF of RA patients and analysed by flow cytometry for expression of the proliferation marker Ki-67 and binding of the apoptosis marker annexin V. Sorted Treg cells of RA patients were analysed for expression of anti-apoptotic regulators Bcl-2 and microRNA-21 (miR-21) by RT-PCR. RESULTS: Treg cells displaying a memory phenotype were abundant in the SF of RA patients. SF Treg cells more frequently expressed the proliferation marker Ki-67 than conventional T cells. Only few SF Treg cells were apoptotic, as indicated by limited annexin V staining of these cells. SF Treg cells displayed high transcription levels of Bcl-2 and miR-21 in comparison with SF conventional T cells and peripheral blood Treg cells. CONCLUSION: Treg cells with a memory phenotype accumulate in the SF of RA patients. These Treg cells have a high proliferative activity and demonstrate little apoptosis. The latter finding could be explained by high transcription of Bcl-2 and miR-21 in SF Treg cells. This article was published in Rheumatology (Oxford) and referenced in Immunotherapy: Open Access
