    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
