Role of endotoxin in tumor necrosis factor alpha expression from alveolar macrophages treated with urban air particles.

abstract：BACKGROUND:HSPGs are glycoproteins containing covalently attached heparan sulfate (HS) chains which bind to growth factors, chemokines, etc., and regulate various aspects of inflammation including cell recruitment. We previously showed that deletion of endothelial N-acetylglucosamine N-deacetylase-N-sulfotransferase-1 ...
