TGF-β is required for both Foxp3(+) regulatory T cell (Treg) and Th17 commitment. Plasmacytoid DCs (pDC) have been shown to participate to both Treg and Th17 commitment as well. However, few studies have evaluated the direct effect of TGF-β on pDC, and to our knowledge, no study has assessed the capacity of TGF-β-exposed pDC to polarize naive CD4(+) T cells. In this paper, we show that TGF-β-tr...

This study examines the potential role of transforming growth factor beta (TGF-beta) in the regulation of human T lymphocyte proliferation, and proposes that TGF-beta is an important autoregulatory lymphokine that limits T lymphocyte clonal expansion, and that TGF-beta production by T lymphocytes is important in T cell interactions with other cell types. TGF-beta was shown to inhibit IL-2-depen...

Transforming growth factor β (TGF-β) is a multifunctional cytokine that is synthesized by many types of cells and regulates the cell cycle. Increasing evidence has led to TGF-β receiving increased and deserved attention in recent years because it may play a potentially novel and critical role in the development and progression of myocardial fibrosis and the subsequent progress of ventricular re...

Transforming growth factor beta (TGF-beta), a multifunctional cytokine that regulates a variety of biological functions, signals through a heteromeric receptor complex of the type I and type II TGF-beta receptors. The type II receptor, a transmembrane serine-threonine kinase, was cloned based on its ability to directly bind TGF-beta. Recently, a number of candidate type I TGF-beta receptors hav...

The epithelial‑mesenchymal transition (EMT) of retinal pigment epithelial (RPE) cells is an important underlying mechanism proliferative vitreoretinopathy (PVR). We previously found that L‑carnitine (β‑hydroxy‑γ‑N-trimethylammonium‑butyrate, LC) was significantly lower during the transforming growth factor‑β1 (TGF‑β1)‑induced EMT process in ARPE‑19 cells. present study assessed role LC RPE migr...

Abstract We provide evidence that Terrestrial Gamma‐Ray Flashes (TGFs), in well isolated thunderstorms, tend to occur during periods of low and declining flash rates, when the amplitudes are larger than average. This conclusion comes from examining results 371 manually tracked TGF‐producing thunderstorms. Fermi‐GBM identified TGFs used for this analysis lightning data come both World Wide Light...

Transforming growth factor (TGF)-beta(1) is one of the most pleiotropic and multifunctional peptides known. While the cardioprotective effect of TGF-beta(1) during ischemia is well known, the specific role of TGF-beta(1) in altering the cardiac remodeling process remains unclear. This study was designed to examine the regulation of hypoxia-reoxygenation-mediated collagen type I expression and a...

Members of the transforming growth factor-beta (TGF-beta) superfamily signal through their cognate receptors to determine cell phenotypes during embryogenesis. Our previous studies on the regulation of first branchial arch morphogenesis have identified critical components of a hierarchy of different TGF-beta isoforms and their possible functions in regulating tooth and cartilage formation durin...

Tolerogenic dendritic cells (DCs) may be valuable in transplantation for silencing immune reaction. Macrophage colony-stimulating factor (M-CSF)/IL-4 induces differentiation of cord blood (CB) monocytes into DCs (M-DCs) with tolerogenic phenotype/function. We assessed whether factors produced by tolerogenic DCs could modulate hematopoiesis. TGF-beta1 added to CB M-DC cultures induced bona fide ...
