Our study reveals that BTN3A1 up-regulation on monocytes in psoriasis patients can result in the hyperactivation of Vγ9Vδ2 T cells. This work also indicates that IFN-γ may amplify Vγ9Vδ2 T cell activation through the up-regulation of BTN3A1 on monocytes via a positive feedback loop. More important, our work provides insight into the molecular mechanisms of Vγ9Vδ2 T cell activation and highlights BTN3A1 as a potential therapeutic target for psoriasis. We believe that these findings could be of interest to the fields of both clinical medicine and basic immunology. Vγ9Vδ2 T cells play an important role in the development and progression of psoriasis vulgaris (PV), but how they promote skin inflammation and the molecular mechanisms underlying Vγ9Vδ2 T cell dysfunction are poorly understood. Here, we show that circulating Vγ9Vδ2 T cells are decreased and exhibit enhanced proliferation and increased production of IFN-γ and TNF-α in PV patients. Monocytes from PV patients express higher levels of the phosphoantigen sensor butyrophilin 3A1 (BTN3A1) than monocytes from healthy controls. Blockade of BTN3A1 suppresses Vγ9Vδ2 T cell activation and abolishes the difference in Vγ9Vδ2 T cell activation between PV patients and healthy controls. The CD14+ cells in PV skin lesions highly express BTN3A1 and juxtapose to Vδ2 T cells. In addition, IFN-γ induces the up-regulation of BTN3A1 on monocytes. Collectively, our results demonstrate a crucial role of BTN3A1 on monocytes in regulating Vγ9Vδ2 T cell activation and highlight BTN3A1 as a potential therapeutic target for psoriasis.
