CD28 and CTLA-4 are opposing regulators of T cell activation, triggered by the two ligands CD80 and CD86. How these ligands promote either T cell activation via CD28 or inhibition via CTLA-4 is not understood. Using CD80 and CD86 molecules expressed on transfected cells, we have identified a major d
