Unveiling the Role of PD-L1 in Vascular Endothelial Dysfunction: Insights into the mtROS/NLRP3/caspase-1 Mediated Pyroptotic Pathway

Programmed death ligand-1(PD-L1) has been postulated to play a crucial role in the regulation of barrier functions of the vascular endothelium, yet how this novel molecule mediates dysfunction in endothelial cells (ECs) during acute lung injury (ALI) remains largely unknown.
