Thymic selection and cell division
Cell division during thymic selection was studied with a system in which purified populations of T cell antigen receptor (TCR)- CD4+8+ (double-positive [DP]) cells and fetal thymic epithelial cells (TEC) were reaggregated in tissue culture. In this system, immature DP cells differentiate into mature single-positive (SP) CD4+8- and CD4-8+ TCRhi cells within 3-4 d, indicative of positive selectio...
متن کاملCd4+ T Cell Division in Irradiated Mice Requires Peptides Distinct from Those Responsible for Thymic Selection
We investigated the mechanism by which alpha/beta T cells expand upon transfer to T cell-deficient host mice by injecting carboxyfluorescein diacetate succinimidyl ester-labeled T cells into mice depleted of T cells by sublethal irradiation. We found that CD4+ T cells divided when transferred to irradiated hosts and that the division of more than half of these cells required class II expression...
متن کاملThymic T-Cell Education: Positive & Negative Selection
TOLERANCE (which is antigen-specific) must be distinguished from immune deficiency (non-specific). Its most important manifestation, the maintenance of SELFTOLERANCE, was originally explained by the Clonal Selection theory as the result of CLONAL ABORTION of self-reactive clones. However, potentially self-reactive Tand B-cells do exist in normal individuals, leading to the recognition of the im...

متن کاملNormal T Cell Selection Occurs in CD205-Deficient Thymic Microenvironments
The thymus imparts a developmental imprint upon T cells, screening beneficial and self-tolerant T cell receptor (TCR) specificities. Cortical thymic epithelial cells (CTEC) present self-peptide self-MHC complexes to thymocytes, positively selecting those with functional TCRs. Importantly, CTEC generate diverse self-peptides through highly specific peptide processing. The array of peptides utili...
