Scope Note
A costimulatory ligand glycoprotein that contains a C2 and V-type IMMUNOGLOBULIN DOMAIN. It is expressed by ANTIGEN-PRESENTING CELLS and binds to CD28 ANTIGEN with high specificity and to CTLA-4 ANTIGEN with low specificity. The interaction of CD86 with CD28 ANTIGEN provides a stimulatory signal to T-LYMPHOCYTES, while its interaction with CTLA-4 ANTIGEN may play a role in inducing PERIPHERAL TOLERANCE.
