PIEZO1 Overexpression Drives Arteriovenous Malformations in Hereditary Hemorrhagic Telangiectasia: A New Therapeutic Target
Highlight
1. PIEZO1, a mechanosensitive ion channel, is overexpressed in endothelial cells of type 2 hereditary hemorrhagic telangiectasia (HHT) lesions.
2. Genetic deletion and pharmacological inhibition of PIEZO1 reduce arteriovenous malformation (AVM) formation in Alk1 knockout mouse models.
3. PIEZO1 signaling modulates key downstream pathways including VEGFR2/AKT, ERK5-p62-KLF4, and endothelial nitric oxide synthase, attenuating hypoxia, inflammation, and endothelial proliferation.
4. Targeting PIEZO1 presents a promising therapeutic strategy for preventing AVMs in ALK1-related vascular diseases.
