How Soluble GARP Enhances TGFβ Activation
GARP (glycoprotein A repetitions predominant) is a cell surface receptor on regulatory T-lymphocytes, platelets, hepatic stellate cells and certain cancer cells. Its described function is the binding and accommodation of latent TGFβ (transforming growth factor), before the activation and release of the mature cytokine. For regulatory T cells it was shown that a knockdown of GARP or a treatment ...
متن کاملEffector Tregs: middle-men in TGFβ activation
Regulatory T-cells (Tregs) are an inherent suppressive cell of the immune system with an established developmental requirement for the cytokine transforming growth factor β (TGFβ). However, the precise mechanisms by which mature Tregs utilize TGFβ during disease are unclear. In the May issue of Immunity, we have demonstrated that effector regulatory T-cells are essential activators of latent-TG...
متن کاملAPPL proteins promote TGFβ-induced nuclear transport of the TGFβ type I receptor intracellular domain
The multifunctional cytokine transforming growth factor-β (TGFβ) is produced by several types of cancers, including prostate cancer, and promote tumour progression in autocrine and paracrine manners. In response to ligand binding, the TGFβ type I receptor (TβRI) activates Smad and non-Smad signalling pathways. The ubiquitin-ligase tumour necrosis factor receptor-associated factor 6 (TRAF6) was ...
متن کاملThe Dynamic Process of β2-Adrenergic Receptor Activation
G-protein-coupled receptors (GPCRs) can modulate diverse signaling pathways, often in a ligand-specific manner. The full range of functionally relevant GPCR conformations is poorly understood. Here, we use NMR spectroscopy to characterize the conformational dynamics of the transmembrane core of the β(2)-adrenergic receptor (β(2)AR), a prototypical GPCR. We labeled β(2)AR with (13)CH(3)ε-methion...
متن کاملActivation of the TGFβ pathway impairs endothelial to haematopoietic transition
The endothelial to haematopoietic transition (EHT) is a key developmental process where a drastic change of endothelial cell morphology leads to the formation of blood stem and progenitor cells during embryogenesis. As TGFβ signalling triggers a similar event during embryonic development called epithelial to mesenchymal transition (EMT), we hypothesised that TGFβ activity could play a similar r...
