WebNov 11, 2016 · Tregs plasticity during prolonged and advanced atherosclerosis might even result in the generation of highly autoaggressive lymphocytes that no longer express Foxp3. 21 In unstable human plaques, Foxp3+ Treg numbers are greatly reduced compared with stable plaques. 6 Whether Treg plasticity contributes to such reductions and greatly … Web2.1. Tregs Subsets in Health and Disease. Work with animal models has shown that more Tregs subsets exist, which parallel the T-helper cell subsets [].Most of these studies were in mice, as analogous subsets in humans are more difficult to study because of lack of accurate identification markers [9,10].Tregs expressing the Th1 factor T-bet exist, which …

WebApr 5, 2024 · Foxp3 mainly acts as a transcriptional repressor and thereby contributes to the characteristics of Treg cells. Foxp3 target genes are predominantly activated by TCR stimulation such as Zap70, Ptpn22, and Itk. Foxp3 also represses IL-2 production and also Satb1 to inhibit the expression of pro-inflammatory cytokines [ 22, 23, 24, 25 ]. Web1 day ago · Consistent with a phenotypic Treg-to-Tex transition, we observed that multiple effector- and exhaustion-associated genes, such as GZMB, PRF1, IFNG, LAG3, and PDCD1, were upregulated within Tex-like cells, while Treg markers, such as FOXP3, IL2RA, and CTLA4, displayed reduced expression (Figure 5 H). These results indicate the …
