Comparisons between untreated primary cells T-cell precursors from the thymus. CD69- thymocytes are from Zap70-deficent mice and are >95% CD4+CD8+. These cells fail to generate intrathymic TCR signals as a result of their lacking Zap70 molecules, and are thus representative of "preselection" CD4+CD8...
