Cd4 foxp3 tregs
WebCommon phenotypic features of CD8 + FOXP3 + T cells and CD4 + Tregs include expression of CD25, CD103, GITR, CTLA-4 in mice, as well as in human [ 12, 15, 20 ]. Since the expression of FOXP3 in CD8 + thymocytes is negligible [ 21 ], it is believed that CD8 + FOXP3 + Tregs develop exclusively from the peripheral CD8 + T-cell pool [ 19 ]. WebThe major Treg population is CD4+, CD25+, CD127- with expression of intracellular FOXP3. Decreased Tregs occur in autoimmune disorders including allergy and asthma. Low numbers or compromised function of Tregs are found in graft vs host disease following bone marrow transplantation.
