Exosomal TGM2 From Hypoxia‐Primed Olfactory Mucosa MSCs Attenuates Senescent Astrocytes via NRF1/TFAM Signaling in Parkinson's Disease

open access: yesComprehensive Physiology, Volume 16, Issue 4, August 2026.
Hypoxia‐preconditioned olfactory mucosa mesenchymal stem cells (OM‐MSCs) release exosomes enriched with transglutaminase 2 (TGM2), which are taken up by astrocytes. Inside the nucleus, TGM2 activates NRF1, leading to the upregulation of TFAM. This enhances mitochondrial function by reducing mitochondrial DNA (mtDNA) leakage and improving mitochondrial ...
