INTRODUCTION: Infliximab is a chimeric monoclonal antibody against tumor necrosis factor alpha (TNF-alpha) that has been introduced recently for Behçet's disease (BD) patients who were resistant to standard treatment. The aim of this study was to analyse the functional changes of Vgamma9/Vdelta2 T lymphocytes in both active and inactive disease and the effect of infliximab on Vgamma9/Vdelta2 T cell expansion, activation and cytotoxicity. METHODS: We investigated 1) cell expansion, 2) expression of TNFRII receptor, 3) perforin and gamma interferon (IFN) content, 4) release of granzyme A (GrA) and 5) phenotype changes, in vitro and in vivo, in Vgamma9/Vdelta2 T lymphocytes by means of fluores…
