BAFF Detection Service

B-cell activating factor (BAFF) is a protein involved in immune regulation and abnormally expressed in some immune diseases. Therefore, it may be used as a potential biomarker in the research of immune diseases. Creative BioMart Biomarker has a wealth of biomarker detection experience, which can provide researchers with accurate, fast and reliable detection results and help customers accelerate research progress.

BAFF

BAFF, also known as B Lymphocyte Stimulator (BLyS), is a member of tumor necrosis factor ligand superfamily. BAFF is produced by monocytes, macrophages, neutrophils and activated T lymphocytes. BAFF can regulate the immune response and has the biological function of promoting the survival and maturation of B cells. In addition, BAFF can also promote the proliferation, differentiation and activation of T cells. BAFF can be expressed in two forms, one is membrane-bound protein (mBAFF) and the other is soluble protein (sBAFF). sBAFF is released after the proteolytic cleavage of furin protease site by metalloproteases. It can exist in the form of trimers or polymers, as well as glycosylated or non-glycosylated forms. BAFF can bind to three receptors, including BAFF receptor (BAFF-R), B cell maturation antigen (BCMA), transmembrane activator and calcium modulator and cytophilin ligand interactor (TACI). BAFF-R, TACI and BCMA are expressed in immature B cells, mature memory B cells and plasma cells, respectively. The combination of BAFF and BAFF-R triggers the non-canonical nuclear factor-κB (NF-κB) signaling pathway, and the BAFF-R signaling pathway is essential for peripheral B cell survival and differentiation, germinal centre formation, plasma cell survival and immunoglobulin class switching. At the same time, the balance between the signal pathway mediated by BCMA and BAFF-R is related to the development of Tfh cells, so BAFF may regulate autoimmunity through the expansion of Tfh cells. In addition, BAFF has elevated expression in both SLE and AAV patients and has been used as a target for research on these diseases.
