SUBCELLULAR LOCALIZATION	plasma membrane
text	membrane protein type 1

basic FUNCTION	involved in the costimulatory signal essential for t lymphocytes activation
	T cell proliferation and cytokine production
	playing a role in stimulating T lymphocyte activation
	direct signaling through CD86/CD80 is a potent regulator of IgG secretion by previously activated B cells
	CD80/CD86 engagement results in DC production of the pro-inflammatory cytokine IL6, which is necessary for full T cell activation
	distinct but complementary roles of CD80 and CD86 IgV and IgC domains in T cell activation

INTERACTION

DNA

RNA

small molecule

protein	CD28, CD86 ligand
	SPI1 is a critical factor for the expression of CD80 and CD86
	interaction of CD86, CD80 with appropriate receptors is essential for an effective T cell response
