2018年7月25日 · 上表中的Foxp3+Treg抑制机制再详细补充一下,Foxp3 + Tregs可以抑制许多不同类型的效应细胞,并且还可以在多个阶段抑制免疫应答,包括淋巴结中的初始细胞和炎症部位的效应细胞。 确切的机制尚不清楚,但已经提出了许多理论,Foxp3 + Tregs很可能通过细胞接触的方式,竞争性结合抗原递呈细胞(APC)上的刺激配体、结合必需的生长因子(如IL-2)、或将尚未明确的负调控信号直接传递到T细胞或APC。 此外,Tregs也可以通过细胞因子IL-10、IL-35 …
tTregs, pTregs, and iTregs: Similarities and Differences - PMC
Foxp3 + T-regulatory cells (Tregs) are primarily generated in the thymus (tTreg), but also may be generated extrathymically at peripheral sites (pTreg), or induced in cell culture (iTreg) in the presence of transforming growth factor β (TGFβ).

2025年3月25日 · These so-called tTreg “private” genes were enriched in pathways related to cell motility, T-cell functional specification, and inflammatory responses. Importantly, 163 tTreg “private” genes were significantly less expressed in circulating naïve and memory Tregs, supporting their role in Treg development in the human thymus. 2 Methods
T Cell Receptor Signaling in the Control of Regulatory T Cell ...
Regulatory T cells (T Reg cells), a specialized T cell lineage, have a pivotal function in the control of self-tolerance and inflammatory responses.
The role of thymus- and extrathymus-derived regulatory T cells in ...
2023年2月2日 · Regulatory T (Treg) cells could be divided into thymus-derived Treg (tTreg) cells and peripherally derived Treg (pTreg) cells, and in vitro induced Treg (iTreg) cells. To date, the functions of tTreg versus pTreg and their relative contributions to maternal-fetal immune tolerance remain insufficiently defined due to a lack of a specific marker ...
