Vγ9Vδ2 T cells are specifically activated by small phosphorylated metabolites called phosphoantigens (PAg). Stress-induced changes in target cell PAg levels are specifically detected by butyrophilin (BTN)3A1, using its intracellular B30.2 domain. This leads to the activation of Vγ9Vδ2 T cells. In this study, we show that changes in the juxtamembrane domain of BTN3A1, but not its transmembrane domain, induce a markedly enhanced or reduced γδ T cell reactivity. There is thus a specific requirement for BTN3A1’s juxtamembrane domain for correct γδ T cell–related function. This work identified, as being of particular importance, a juxtamembrane domain region of BTN3A molecules identified as a possible dimerization interface and that is located close to the start of the B30.2 domain.}, pages = {4228--4234}, title = {The Juxtamembrane Domain of Butyrophilin BTN3A1 Controls Phosphoantigen-Mediated Activation of Human Vγ9Vδ2 T Cells}, volume = {198}, year = {2017} }
