The thymus is the major site of T cell development and repertoire selection. During these processes, T cells segregate into two subsets that express either CD4 or CD8 accessory molecules, the phenotype of peripheral T cells. Analysis of CD4+8- thymocytes revealed that the majority of these cells express the heat-stable Ag (HSA) but not the nonclassical class I Ag, Qa-2. This HSA+, Qa-2- phenotype is similar to that of the less mature, CD4+8+ thymocytes. The remaining CD4+8- thymocytes possess… CONTINUE READING
