Thymosin beta 4 is an endogenous iron chelator and molecular switch of ferroptosis
Summary
Revealed a previously unknown function of Thymosin Beta-4 as an endogenous iron chelator that can regulate ferroptosis. This discovery provides a new mechanistic understanding of Tβ4's cytoprotective effects and opens potential research avenues in iron-related pathologies.
Key Findings
- Thymosin β4 directly chelates iron through specific amino acid residues
- Acts as a molecular switch that can inhibit ferroptotic cell death
- May explain previously observed cytoprotective effects through iron homeostasis regulation
