TB-500 Peptide
TB-500, the synthetic analog of Thymosin Beta-4 (Tβ4), is a 43-amino-acid peptide derived from the TMSB4X gene. It has been studied for its angiogenic, regenerative, and anti-inflammatory properties, with potential applications in wound healing, neurological recovery, and tissue repair.
Mechanism of Action
TB-500 interacts with actin-binding sites, influencing cell migration and cytoskeletal remodeling—critical for tissue regeneration. It modulates G-actin sequestration, increasing availability for cellular motility, which may impact wound healing, tissue repair, and metastatic potential.
Biological Significance
Detected in blood plasma and wound exudates, TB-500 may stimulate angiogenesis, enhance collagen deposition, and regulate ATP synthase activity, influencing intracellular and extracellular healing processes.
Research Highlights
- Wound Healing: Studies indicate accelerated re-epithelialization and wound contraction, with enhanced vascularization and collagen synthesis.
- Cardiac Regeneration: Preliminary research suggests TB-500 may reduce ventricular hypertrophy, promote angiogenesis, and enhance cardiomyocyte resilience under hypoxic conditions.
- Anti-Inflammatory Action: Modulates microRNA-146a, potentially inhibiting pro-inflammatory pathways via IRAK1 and TRAF6 regulation.
- Hair Follicle Growth: Investigations show TB-500 may increase hair shaft density through altered mRNA and protein expression in dermal tissue.
