| pubmed-article:9678757 | pubmed:abstractText | Thymocytes bearing autoreactive TCR are eliminated from the organism by a process termed negative selection. The molecular basis of this deletion has been recently shown to be a consequence of TCR-triggered activation of a caspase by certain peptide-MHC ligands in the immature CD4+CD8+ double-positive (DP) thymocyte subpopulation. Of note, the numerically minor TCRhigh DP thymocyte subpopulation, unlike the major TCRlow DP subset, is resistant to negative selection. Despite exposure to cognate peptide, TCRhigh DP thymocytes mature into single-positive thymocytes and are exported into the periphery. Here we investigated the mechanism by which these thymocytes escape negative selection. Using a cytochemical assay in conjunction with a caspase-specific affinity ligand, we demonstrate that the resistance of the TCRhigh DP thymocytes to negative selection correlates with the disappearance of TCR-triggered caspase activity in these cells. Thus thymocytes which have presumably begun the positive selection process inactivate the thymic caspase pathway and are no longer susceptible to negative selection. | lld:pubmed |
