B7 Antigens. Antigen, B7 . B-7 Antigen . B7 Antigen . B7 Costimulatory Molecules . B7 Molecules . Antigen, B-7 . Antigens, B7 . B 7 Antigen . Costimulatory Molecules, B7 . Molecules, B7 . A family of cell-surface proteins found on ANTIGEN-PRESENTING CELLS. B7 antigens are ligands for specific cell surface receptor subtypes found on T-CELLS. They play an immunomodulatory role by stimulating or inhibiting the T-CELL activation process. . 1.00

Ligand, B7-1 . B7-1 Costimulatory Molecule . B-Cell Activation Antigen . CD80 Antigens . Antigens, CD80 . Antigen, B7 . B7 Antigen . A costimulatory ligand membrane glycoprotein that contains a V2 type and C2 IMMUNOGLOBULIN DOMAIN and is expressed by ANTIGEN-PRESENTING CELLS. It binds to CTLA-4 ANTIGEN with high specificity and to CD28 ANTIGEN with low specificity. The interaction of CD80 with CD28 ANTIGEN provides a costimulatory signal to T-LYMPHOCYTES, while its interaction with CTLA-4 ANTIGEN may play a role in inducing PERIPHERAL TOLERANCE. . 1.00
