CD40 Antigens. CD40 Antigen . CDw40 Antigen . TNFRSF5 Receptor . Antigen, CD40 . Antigen, CDw40 . Receptor, TNFRSF5 . Antigens, CD40 . Tumor Necrosis Factor Receptor Superfamily, Member 5 . Members of the tumor necrosis factor receptor superfamily with specificity for CD40 LIGAND. They are found on mature B-LYMPHOCYTES, some EPITHELIAL CELLS; and lymphoid DENDRITIC CELLS. Evidence suggests that CD40-dependent activation of B-cells is important for generation of memory B-cells within the germinal centers. Mutations in the CD40 antigen gene result in HYPER-IGM IMMUNODEFICIENCY SYNDROME, TYPE 3. Signaling of the receptor occurs through its association with TNF RECEPTOR-ASSOCIATED FACTORS. . 1.00

T-Cell T4 Antigens . T4 Antigens, T Cell . Antigens, CD4 . CD4 Molecule . CD4 Receptors . Receptors, CD4 . T4 Antigens, T-Cell . 55-kDa antigens found on HELPER-INDUCER T-LYMPHOCYTES and on a variety of other immune cell types. They are members of the immunoglobulin supergene family and are implicated as associative recognition elements in MAJOR HISTOCOMPATIBILITY COMPLEX class II-restricted immune responses. On T-lymphocytes they define the helper/inducer subset. T4 antigens also serve as INTERLEUKIN-15 receptors and bind to the HIV receptors, binding directly to the HIV ENVELOPE PROTEIN GP120. . 0.93

Protein Tyrosine Phosphatase, Receptor Type, C . RT7 Antigens . B220 Antigens . High-molecular weight glycoproteins uniquely expressed on the surface of LEUKOCYTES and their hemopoietic progenitors. They contain two FIBRONECTIN TYPE III DOMAINS and possess cytoplasmic protein tyrosine phosphatase activity, which plays a role in intracellular signaling from the CELL SURFACE RECEPTORS. Leukocyte common antigens occur as multiple isoforms that result from alternative mRNA splicing and differential usage of three exons. . 0.86
