Background
| Relevance | Transforming growth factor beta-1: Multifunctional protein that regulates the growth and differentiation of various cell types and is involved in various processes, such as normal development, immune function, microglia function and responses to neurodegeneration . Activation into mature form follows different steps: following cleavage of the proprotein in the Golgi apparatus, Latency-associated peptide and Transforming growth factor beta-1 chains remain non-covalently linked rendering TGF-beta-1 inactive during storage in extracellular matrix . At the same time, LAP chain interacts with 'milieu molecules', such as LTBP1, LRRC32/GARP and LRRC33/NRROS that control activation of TGF-beta-1 and maintain it in a latent state during storage in extracellular milieus. TGF-beta-1 is released from LAP by integrins : integrin-binding to LAP stabilizes an alternative conformation of the LAP bowtie tail and results in distortion of the LAP chain and subsequent release of the active TGF-beta-1 . Once activated following release of LAP, TGF-beta-1 acts by binding to TGF-beta receptors , which transduce signal . While expressed by many cells types, TGF-beta-1 only has a very localized range of action within cell environment thanks to fine regulation of its activation by Latency-associated peptide chain and 'milieu molecules' . Plays an important role in bone remodeling: acts as a potent stimulator of osteoblastic bone formation, causing chemotaxis, proliferation and differentiation in committed osteoblasts . Can promote either T-helper 17 cells or regulatory T-cells lineage differentiation in a concentration-dependent manner . At high concentrations, leads to FOXP3-mediated suppression of RORC and down-regulation of IL-17 expression, favoring Treg cell development . At low concentrations in concert with IL-6 and IL-21, leads to expression of the IL-17 and IL-23 receptors, favoring differentiation to Th17 cells . Stimulates sustained production of collagen through the activation of CREB3L1 by regulated intramembrane proteolysis . Mediates SMAD2/3 activation by inducing its phosphorylation and subsequent translocation to the nucleus. Can induce epithelial-to-mesenchymal transition and cell migration in various cell types . |
