Calcitriol Suppresses Platelet Activation and Thrombosis, Mitigating Cardiovascular Risks in Metabolic Dysfunction-Associated Steatotic Liver Disease.

Metabolic dysfunction-associated steatotic liver disease is associated with vitamin D deficiency, and platelets exhibit hyperactivity. Zhang et al provide novel insights into the mechanisms underlying platelet hyperreactivity and thrombotic risk in patients with metabolic dysfunction-associated steatotic liver disease, demonstrating that calcitriol activates the vitamin D receptor in megakaryocytes and platelets, leading to the downregulation of P2Y12 expression and the modulation of the cyclic adenosine monophosphate/protein kinase A and mitogen-activated protein kinase signaling pathways, thereby attenuating platelet activation.
