Study on the Thrombolytic Effect of Platelet Membrane Coated Tenecteplase on Human Arterial Thrombus

Platelet Membrane-coated Tenecteplase to Improve Thrombolytic Efficacy by Targeting Thrombus

Tenecteplase (TNK) is the latest generation of specific thrombolytic drugs independently developed in China. This study aims to investigate the thrombolytic efficacy of platelet membrane-coated tenecteplase (PM-TNK) on human ex vivo arterial thrombi, and to explore the inhibitory effects of plasma from patients receiving antiplatelet therapy on its thrombolytic activity, thereby evaluating the future clinical application value of PM-TNK.
