Transforming growth factor beta 1 or TGF-β1 is a polypeptide member of the transforming growth factor beta superfamily of cytokines. It is a secreted protein that performs many cellular functions, including the control of cell growth, cell proliferation, cell differentiation, and apoptosis. In humans, TGF-β1 is encoded by the TGFB1 gene. [5] [6]
Transforming growth factor beta (TGF-β) is a multifunctional cytokine belonging to the transforming growth factor superfamily that includes three [1] different mammalian isoforms (TGF-β 1 to 3, HGNC symbols TGFB1, TGFB2, TGFB3) and many other signaling proteins. TGFB proteins are produced by all white blood cell lineages.
TGF-beta-1 is a peptide of 112 amino acid residues derived by proteolytic cleavage from the C-terminal of a precursor protein. These proteins interact with a conserved family of cell surface serine/threonine-specific protein kinase receptors, and generate intracellular signals using a conserved family of proteins called SMADs .
Tolerogenic DCs also produce different cytokines as mature DCs (e.g. anti-inflammatory cytokines interleukin (IL)-10, transforming growth factor-β (TGF-β)). Moreover, tolerogenic DCs may also express various inhibitory surface molecules (e.g. programmed cell death ligand (PDL)-1, PDL-2) or can modulate metabolic parameters and change T cell ...
The secretion and activation of TGF-betas is regulated by their association with latency-associated proteins and with latent TGF-beta binding proteins. The product of this gene targets latent complexes of transforming growth factor beta to the extracellular matrix, where the latent cytokine is subsequently activated by several different mechanisms.
Transforming growth factor ([attribution needed], or TGF) is used to describe two classes of polypeptide growth factors, TGFα and TGFβ. The name "Transforming Growth Factor" is somewhat arbitrary, since the two classes of TGFs are not structurally or genetically related to one another, and they act through different receptor mechanisms .
A bone growth factor is a growth factor that stimulates the growth of bone tissue. [1] [2]Known bone growth factors include insulin-like growth factor-1 (IGF-1), insulin-like growth factor-2 (IGF-2), transforming growth factor beta (TGF-β), fibroblast growth factors (FGFs), platelet-derived growth factor (PDGF), parathyroid hormone-related peptide (PTHrP), bone morphogenetic proteins (BMPs ...
Transforming growth factor beta (TGF-β) is a potent cell regulatory polypeptide homodimer of 25kD. [1] It is a multifunctional signaling molecule with more than 40 related family members. TGF-β plays a role in a wide array of cellular processes including early embryonic development, cell growth, differentiation, motility, and apoptosis. [2]
