MeSH definition : A costimulatory ligand expressed by ANTIGEN-PRESENTING CELLS that 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.; 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.;
