概括

在调节性T细胞 (Tregs) 中删除CREB会增加它们的频率和抑制功能,这种功能由IL-10介导. 这凸显了CREB在平衡Treg稳定性和免疫抑制方面的双重作用.

科学领域:

免疫学免疫学免疫学
分子生物学分子生物学
细胞生物学细胞生物学

背景情况:

调节性T细胞 (Tregs) 对于免疫平衡至关重要,其特征是Foxp3表达.
福克斯p3的表达受到Treg特异性脱甲基化位 (TSDR) 的调节,该位含有CREB结合位.

研究的目的:

调查CREB删除对Treg发育,稳定性和功能的影响.
阐明CREB在Treg生物学中的作用背后的分子机制.

主要方法:

用Treg频率和表型分析进行流细胞计 (CD25+/Foxp3+).
通过ELISA和RT-qPCR进行细胞因子分析.
基因表达分析 (Affymetrix HTA2),ATAC测序和甲基化试验.
在体内功能评估使用CD4 T细胞介导转移性结肠炎模型.

主要成果:

特定于Foxp3的CREB删除增加了各种器官的Treg频率,但减少了每个细胞的Foxp3表达.
缺乏CREB的Tregs显示IL-33受体 (ST-2),IL-10,IL-13和CREM的表达增强.
这些Tregs在体外表现出强大的抑制能力,并在体内通过IL-10改善大肠炎.

结论:

在Tregs中,CREB扮演着双重的角色:促进Foxp3的表达,与CREM一起,限制ST2位点的染色质可访问性.
这种调节平衡了Treg稳定性和IL-10介导的免疫抑制.
针对Tregs中的CREB可能为炎症性疾病提供治疗策略.

T Cell Types and Functions

T Cell Types and Functions

When T cells with CD4 markers are activated, they give rise to two types of effector cells: helper T cells and regulatory T cells. Meanwhile, T cells with CD8 markers differentiate into effector cytotoxic T cells. The differentiation of CD4 T cells into helper T cell subsets, such as Th1, Th2, and Th17 cells, is dependent on the antigen type, antigen-presenting cell, and regulatory cytokines.
Th1 cells stimulate dendritic cells to express necessary co-stimulatory molecules on their surfaces for...

Master Transcription Regulators

Master Transcription Regulators

Master transcription regulators are regulatory proteins that are predominantly responsible for regulating the expression of multiple genes. Often these genes work in concert to drive a complex process. Activation of a master transcription regulator can lead to a cascade of transcriptional activation necessary for that outcome. These regulators can directly bind to the regulatory sequences of the various genes involved, or they can indirectly regulate transcription by binding to regulatory...

TGF - β Signaling Pathway

TGF - β Signaling Pathway

The TGF-β signaling pathway regulates cell growth, differentiation, adhesion, motility, and development. TGF-β ligands that induce TGF-β signaling are synthesized in their latent form. Several proteases or cell surface receptors such as integrins act upon the latent form, releasing the active ligand. There are three types of mammalian TGF-βs: (TGF-β1, TGF-β2, and TGF-β3) that bind as homodimers or heterodimers to TGF-β receptors. The TGF-β receptors...
