我们的研究表明,银屑病患者单核细胞表面BTN3A1的上调可导致Vγ9Vδ2T细胞的过度激活。本工作还表明,干扰素-γ可能通过正反馈环上调单核细胞表面BTN3A1,从而放大V-γ9V-δ-2T细胞的激活。更重要的是,我们的工作提供了对Vγ9Vδ2T细胞激活的分子机制的洞察,并强调BTN3A1是银屑病的潜在治疗靶点。我们相信,这些发现可能会对临床医学和基础免疫学领域产生兴趣。Vγ9Vδ2 T细胞在寻常型银屑病(PV)的发生发展中起重要作用,但它们如何促进皮肤炎症以及Vγ9Vδ2 T细胞功能障碍的分子机制尚不清楚。在此,我们发现PV患者循环中的V-γ9V-δ-2T细胞减少,增殖增强,产生干扰素-γ和肿瘤坏死因子-α增加。PV患者单核细胞表达磷酸化抗原感受器BTN3A1(BTN3A1)的水平高于健康对照单核细胞。阻断BTN3A1可抑制Vγ9Vδ2T细胞活化,消除PV患者与健康对照组Vγ9Vδ2T细胞活化的差异。PV皮损中CD14+细胞高表达BTN3A1,并与V-δ-2T细胞并列。此外,干扰素-γ还可诱导单核细胞BTN3A1表达上调。总之,我们的结果证明了BTN3A1在调节Vγ9Vδ2T细胞激活中的关键作用,并强调BTN3A1是银屑病的潜在治疗靶点。
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.
