This research highlights the increasing global prevalence of HFpEF and positions Goreisan as a potential novel therapeutic option in cardiovascular treatment, warranting further clinical investigation.
Nesfatin-1 ameliorates blood-brain barrier dysfunction in Alzheimer’s disease by targeting VEGF-R1 and reducing cellular senescence in brain vascular endothelial cells
Nesfatin-1 (NF-1) has been shown to improve blood-brain barrier (BBB) dysfunction in Alzheimer's disease (AD) by targeting VEGF-R1 and reducing cellular senescence in brain endothelial cells. The study found that NF-1 treatment restored the expression of tight junction proteins and mitigated the permeability increase induced by oligomerized Aβ1-42. In transgenic AD mouse models, NF-1 administration decreased VEGF-R1 levels, suggesting a protective role for NF-1 in maintaining BBB integrity and offering a potential therapeutic avenue for AD.
