Phenotype and functional changes of Vγ9/Vδ2 T lymphocytes in Behçet's disease and the effect of infliximab on Vγ9/Vδ2 T cell expansion, activation and cytotoxicity
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 c...
متن کاملHuman Vγ9/Vδ2 T cells: Innate adaptors of the immune system.
Unconventional T cells are gaining center stage as important effector and regulatory cells that orchestrate innate and adaptive immune responses. Human Vγ9/Vδ2 T cells are amongst the best understood unconventional T cells, as they are easily accessible in peripheral blood, can readily be expanded and manipulated in vitro, respond to microbial infections in vivo and can be exploited for novel t...
متن کاملFunctional Inactivation in the Whole Population of Human Vγ9/Vδ2 T Lymphocytes Induced By a Nonpeptidic Antagonist
Nonpeptidic compounds stimulate human T cells bearing the TCR-gamma delta in the absence of major histocompatibility complex restriction. We report that one of these ligands, 2,3-diphosphoglyceric acid (DPG), which induces expansion of V gamma 9/V delta T cells ex vivo, antagonizes the same cell population after repetitive activation. Stimulation with DPG results in partial early protein tyrosi...
متن کاملThe Vγ9Vδ2 T Cell Antigen Receptor and Butyrophilin-3 A1: Models of Interaction, the Possibility of Co-Evolution, and the Case of Dendritic Epidermal T Cells
Most circulating human gamma delta T cells are Vγ9Vδ2 T cells. Their hallmark is the expression of T cell antigen receptors (TCR) whose γ-chains show a Vγ9-JP (Vγ2-Jγ1.2) rearrangement and are paired with Vδ2-containing δ-chains, a dominant TCR configuration, which until recently seemed to occur in primates only. Vγ9Vδ2 T cells respond to phosphoantigens (PAg) such as (E)-4-Hydroxy-3-methyl-but...
متن کاملA butyrophilin family member critically inhibits T cell activation.
The costimulatory molecules in the B7-CD28 families are important in the regulation of T cell activation and tolerance. The butyrophilin family of proteins shares sequence and structure homology with B7 family molecules; however, the function of the butyrophilin family in the immune system has not been defined. In this study, we performed an analysis on multiple butyrophilin molecules and found...
