MeSH Heading: B7-1 Antigen
Tree Number(s): D12.776.467.150.100; D12.776.543.095.100; D23.050.301.285.100; D23.529.168.100
Unique ID: D018122
RDF Unique Identifier: http://id.nlm.nih.gov/mesh/D018122
Scope Note: 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.
