A differentiation pathway from CD4+CD8+ cells to CD4+CD8- or CD4-CD8+ cells was investigated in athymic nude mice. Using fluorescence-activated cell sorter, CD4+CD8+ cells were sorted out from AKR thymocytes (H-2k, Thy-1.1) stained with two monoclonal antibodies against CD4 and CD8 (anti-L3T4 and an
## Abstract In normal mice, more than 10% of thymocytes in the CD4^+^CD8^β^ and CD4^β^CD8^+^ singleβpositive (SP) subsets express a medium level of CD3 on the cell surface. However, the fate of CD3^medium^ cells is unclear. The CD3^medium^ SP subpopulations might contain (i) cells in an immature st
