    basic FUNCTION
  • costimulatory molecule for the priming and activation of na
  • ve and memory T cells, respectively
  • expression of CD86 on islet endothelial cells facilitates T cell adhesion and migration
  • direct signaling through CD86/CD80 is a potent regulator of IgG secretion by previously activated B cells
  • rapidly internalized in cells expressing MARCH1, leading to lysosome-dependent degradation
  • its ubiquitination appears to promote endocytosis and direct CD86 to lysosomes where it cannot be efficiently retrieved to the cell surface even when lysosomal degradation is inhibited
  • critical importance of the cytoskeleton-dependent CD86 polarization to the immunological synapse (IS) and more specifically the K4 motif for effective co-signaling
  • CD80/CD86 engagement results in DC production of the pro-inflammatory cytokine IL6, which is necessary for full T cell activation
  • expression levels of CD86 are tightly regulated, being actively decreased by regulatory T cells and increased in response to pathogen-derived signals
  • distinct but complementary roles of CD80 and CD86 IgV and IgC domains in T cell activation
    a component
    small molecule
  • IFNG
  • ligand of TCR antigen CD28
  • SPI1 is a critical factor for the expression of CD80 and CD86
  • ubiquitinated in dendritic cells via MARCH1 E3 ubiquitin ligase and that this ubiquitination plays a key role in CD86 regulation
  • CD86 is rapidly endocytosed in the presence of MARCH1 followed by lysosome-dependent degradation
  • CD86 ubiquitination by MARCH1 occurs post-endoplasmic reticulum
  • IL2 upregulates CD86 expression on human CD4(+) and CD8(+) T cells via a receptor-dependent mechanism that involves the NFATC1 and mammalian target of rapamycin pathways
  • PHB/PHB2 and the CD86 cytoplasmic domain cooperate to mediate CD86 signaling in a B cell through differential phosphorylation of distal signaling intermediates required to increase IGHG1
  • interaction of CD86, CD80 with appropriate receptors is essential for an effective T cell response
  • role for IL21 as an inducer of the costimulatory ligand CD86 on B lymphocytes
  • DEF103B induces the costimulatory molecule CD86 on primary monocytes by a mechanism involving autocrine activation of ionotropic P2RX7 by ATP
  • decreased CD1D is associated with CD86 over-expression in B cells from systemic lupus erythematosus
