Porcine endothelium supports transendothelial migration of human leukocyte subpopulations as efficiently as human endothelium. Incompatibilities in some adhesion receptor pairs may be compensated for by other adhesion receptor pairs, as exemplified by human NK cells whose migration across human, but not pig, endothelium was blocked by anti-CD18 antibodies. Antiporcine vascular cell adhesion molecule-1 antibodies may be used as species-specific blockers of transendothelial NK cell and monocyte migration, and as such may prove to be useful inhibitors of cellular organ xenograft rejection.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
