Abstract excerpt
Platelet dysfunction drives bleeding complications in patients with advanced chronic kidney disease (CKD), worsening clinical outcomes. However, the underlying mechanisms remain unclear, limiting treatment options. In this study, we identified the expression of urea transporter B (SLC14A1/UT-B) in human and mouse platelets. By analyzing a clinical cohort of patients with CKD, we demonstrated that...
