GP IIb/IIIa-ICAM-1 Mediated Platelet-Endothelial Adhesion Exacerbates Pulmonary Hypertension

GSE283520 Homo sapiens Expression profiling by high throughput sequencing 13 samples 2024/12/09 GPL21697
Summary
Pulmonary hypertension (PH) patients typically present with a diminished platelet count, but the role of platelets in the development and progression of PH remains unclear.Transcriptomic analysis revealed that platelets from PH patients exhibited an upregulation of genes associated with cellular adhesion, platelet activation, and adhesion. Notably, the hub genes, glycoprotein IIb/IIIa (GP IIb/IIIa), were implicated in mediating platelet-endothelium adhesion through their interaction with intercellular adhesion molecule-1 (ICAM-1) on pulmonary artery endothelial cells, triggering platelet activation and the subsequent release of platelet-derived growth factor BB (PDGF-BB).
