CD19 functions as a coreceptor for the B-cell antigen receptor complex, lowering the threshold for antigen-triggered B-cell activation. CD19 signalling can activate phosphatidylinositol 3-kinase pathways and mobilise intracellular calcium, supporting normal B-cell differentiation, proliferation and antibody responses.
CD19 / B-lymphocyte antigen CD19 is widely studied in B-cell development, B-cell receptor signalling, immunophenotyping and immune-oncology research.
