A synthetic peptide fragment of thymosin beta-4, researched for wound healing and tissue repair.
BACKGROUND: Thymosin beta-4 (Tβ4) is a ubiquitous protein with many properties relating to cell proliferation and differentiation that promotes wound healing and modulates inflammatory mediators. The mechanism by which Tβ4 modulates cardiac protectio…
Thymosin beta-4 (Tβ(4)) is a major actin-sequestering molecule that contributes to cell growth, differentiation, motility, survival, mitosis and angiogenesis. It is overexpressed in certain type of carcinoma and fibrosarcoma cell lines and is associa…
Peripheral neuropathy is one of the most common complications of diabetes mellitus. Using a mouse model of diabetic peripheral neuropathy, we tested the hypothesis that thymosin β4 (Tβ4) ameliorates diabetes-induced neurovascular dysfunction in the s…
Thymosin β4 (Tβ4) is a small, low-molecular-weight peptide ubiquitously expressed in all cells and extracellular fluids. It is a major actin sequestering protein present in the cells. In addition to this, Tβ4 has also been shown to be involved in end…
The formulation TB-500 is suspected to be used as doping agent in sport. This work describes the detection and the identification of the N-terminal acetylated 17-23 fragment of human thymosin beta 4 (Ac-LKKTETQ) in TB-500 by means of high-performance…
The identification of the different cell types involved in human nephrogenesis, when solely based on morphology, may lead to errors in its interpretation, given the complexity of the histological picture of the fetal and of the newborn kidney. In thi…
Thymosin β4 (Tβ4) is a peptide with multiple biological functions. Here, we focus on the role of Tβ4 in vascularization, and review our studies of the controlled delivery of Tβ4 through its incorporation in biomaterials. Tβ4 promotes vascularization…
Thymosin β4 (Tβ4) is a multifunctional protein that has pleiotropic activities both intracellularly and extracellularly. The mechanisms by which it influences cellular processes such as adhesion, migration, differentiation, or apoptosis are not yet u…
Thymosin β4 (Tβ4) is highly expressed in saliva of human newborns but not in adults. Here preliminary immunohistochemical analyses on different human tissues are reported. Immunoreactivity for Tβ4 in human salivary glands show high quantities of Tβ4…
Thymosin β4 (Tβ4) plays a role in fibrosis, inflammation, and in the reparative process of injured cells and tissues. Here, we discuss our preliminary work on the protective effect of Tβ4 on carbon tetrachloride (CCl(4) )-induced acute hepatotoxicity…
Thymosin β4 (Tβ4) has been found to have several biological activities related to antiscarring and reduced fibrosis. For example, the anti-inflammatory properties of Tβ4 and its splice variant have been shown in the eye and skin. Moreover, Tβ4 treatm…
In previous studies, granulation tissue from subcutaneous sponge implants in rats receiving thymosin β4, a 43-amino acid actin-binding protein that advances wound repair, produced the unexpected absence of myofibroblast populations, along with unifor…
The small actin-binding protein thymosin β4 (Tβ4) is understood to stimulate angiogenesis. Previously, we reported that Tβ4 induces angiogenesis by increasing vascular endothelial growth factor (VEGF) expression, but the mechanism underlying how Tβ4…
Thymosin beta 4 (Tβ4) is a ubiquitous protein with diverse biological functions. The effecter molecules targeted by Tβ4 in cardiac protection remain unknown. We summarize previously published work showing that treatment with Tβ4 in the myocardial inf…
Neurorestorative therapy targets multiple types of parenchymal cells in the intact tissue of injured brain tissue to increase neurogenesis, angiogenesis, oligodendrogenesis, and axonal remodeling during recovery from neurological injury. In our labor…
Thymosin-β4 (Tβ4) is a G-actin sequestering peptide involved in regeneration and remodeling of injured tissues. In this work, we have designed and synthesized three peptide sequences containing the N-terminus (TYB4-n), the central part (TYB4-i) or th…
Thymosin beta 4 (Tβ4) is the major G-actin sequestering molecule and is abundant in lymphoid tissues. However, it is not clear what regulates Tβ4 expression and what its function is on natural killer (NK) cells. We investigated whether interleukin-18…
Thymosin beta4 (43 aa) is a highly conserved acidic peptide which regulates actin polymerization in mammalian cells by sequestering globular actin. Thymosin beta4 is undergoing clinical trials as a drug for the treatment of venous stasis ulcers, corn…
It is still relatively unclear how intervertebral disc (IVD) cells sense a mechanical stimulus and convert this signal into a biochemical response. Previous studies demonstrated that the cytoskeletal elements are mechano-responsive in many cell types…
BACKGROUND: Thymosin β4 was recently demonstrated to be a potential stimulator of angiogenesis and arteriogenesis in both in-vivo and in-vitro studies. Little is known about the relationship between serum thymosin β4 levels and the extent of coronary…
