anti- BTNL2 antibody

Background

Butyrophilin like 2 (BTNL2) is an immunomodulatory protein expressed in epithelial and lymphoid tissues. BTNL2 interacts with T cells, modulating their activation and proliferation, thus playing a key role in maintaining immune homeostasis and preventing excessive immune responses. Genetic polymorphisms in BTNL2 are linked to susceptibility to autoimmune diseases, including sarcoidosis, rheumatoid arthritis, and Crohn's disease, as well as some cancers. Its expression in mucosal tissues suggests a role in regulating local immune responses to pathogens and maintaining the epithelial barrier. BTNL2's therapeutic potential is under investigation, particularly its ability to influence immune tolerance and suppress aberrant immune activation in inflammatory diseases and transplant rejection.
