The BTN2A2 (Butyrophilin Subfamily 2 Member A2) antibody targets a protein belonging to the butyrophilin family, which plays roles in immune regulation and lipid metabolism. BTN2A2 is a transmembrane glycoprotein expressed on antigen-presenting cells (APCs) and certain epithelial tissues. Structurally, it contains extracellular immunoglobulin variable (IgV) and constant (IgC) domains, characteristic of immune modulators. Functionally, BTN2A2 interacts with BTN3A1 and γδ T-cell receptors, contributing to phosphoantigen-mediated activation of Vγ9Vδ2 T cells, a subset critical in antimicrobial and antitumor immunity. This interaction highlights its involvement in bridging innate and adaptive immune responses.
BTN2A2 antibodies are primarily used as research tools to study its biological mechanisms, including its role in lipid antigen presentation, T-cell regulation, and associations with autoimmune diseases or cancers. Recent studies suggest BTN2A2 may have dual roles—promoting pro-inflammatory responses in some contexts while suppressing immune activation in others. Antibodies targeting BTN2A2 enable investigations into its ligand-binding properties, signaling pathways, and therapeutic potential. For instance, blocking BTN2A2 antibodies might modulate γδ T-cell activity for cancer immunotherapy, while agonist antibodies could enhance antimicrobial defenses. However, research remains preclinical, requiring further validation of specificity and safety. Understanding BTN2A2's precise functions and its interplay with other butyrophilins may unlock novel immunotherapeutic strategies.
