Early thrombocytopenia during porcine liver xenotransplantation appears to be primarily driven by pVWF-mediated platelet activation rather than by classical immune or splenic mechanisms. Targeted VWF blockade with agents such as caplacizumab may mitigate platelet loss and improve the safety profile of extracorporeal porcine liver support in acute liver failure.
Zhao et al. (Tue,) studied this question.
