Tumor Necrosis Factor Receptor Superfamily Member 13B / CD267 (TNFRSF13B) Antibody

Background

TNFRSF13B, also known as TACI (Transmembrane Activator and CAML Interactor), is a critical receptor in the immune system, specifically involved in B cell biology. TNFRSF13B belongs to the tumor necrosis factor receptor superfamily (TNFRSF) and plays an essential role in immune regulation by binding ligands such as APRIL (a proliferation-inducing ligand) and BAFF (B-cell activating factor). These interactions are vital for B cell survival, proliferation, and differentiation, particularly in the context of generating long-lasting immune responses and maintaining immune homeostasis. Mutations in TNFRSF13B have been linked to various immunodeficiency disorders, such as Common Variable Immunodeficiency (CVID) and IgA deficiency. These conditions are associated with impaired antibody production, resulting in increased susceptibility to infections and autoimmune complications. Due to its importance in regulating immune responses, TNFRSF13B is studied intensively as a therapeutic target for both immunodeficiency disorders and autoimmune diseases where B cell activity is dysregulated.
