Here, we first synthesize the modulation of specific γδ T cell subsets by related BTN/BTNL molecules, in human and mice., BTN1A1 and BTN3A1, known to suppress T cells, appear to have receptors upregulated upon T cell activation. Treatment of T cells with BTN3A2 and BTNL8 significantly increases anti-CD3 induced IL-2 production, suggesting that both BTN3A2 and BTNL8 act as co-stimulatory ligands..
BTN3A1 and BTN2A1 are key proteins that mediate the recognition of phosphoantigens by γδ T cells. Together, they can activate the most abundant subset of γδ T cells in peripheral blood, γ9δ2 T. This non-classical inside-out signaling plays a crucial role in the body's anti-infective, anti-tumor, and immunomodulatory processes., It is generally accepted that the participation of the protein complex composed of up to three members of the BTN protein family, BTN3A1, BTN3A2 and BTN2A1, is critical for effective signaling., The BTN2A1/3A1 complex specifically activates the predominant gamma-delta T cell population in the peripheral blood, comprising the Vg9d2 T cell receptor (TCR), but does not activate the primary gamma-delta T cell population in mucosal tissues, comprising the Vg4 TCR., Our results showcase the feasibility of recombinant BTN2A1/3A1 heterodimers in promoting targeted activation of Vγ9Vδ2 + T cells and demonstrate the requirement of a signal 2 via either a canonical T cell costimulatory receptor or NKR to fully activate BTN-mediated cytotoxicity in Vγ9Vδ2 + T cells., The mevalonate pathway mediates the phosphorylation of antigen metabolites and recruits BTN3A1, allowing BTN2A1 to directly bind to Vγ9 , activate the triplex complex, and activate Vγ9Vδ2 T cells . Despite these promising insights, the dynamic relationship between Vγ9Vδ2 T cells and cancer cells remains incompletely understood., Heat shock proteins, particularly molecular chaperones induced by fever, play pivotal roles in immune activation. Conversely, IgD B cells and gamma/delta T cells contribute to immune deactivation through mechanisms such as clonal anergy..
