title: [Effect of plasma lipoproteins and apolipoprotein A-I on lipopolysaccharide-induced production of reactive oxygen metabolites by Kupffer cells of the rat].
abstract: The effects of plasma lipoproteins on LPS-induced production of reactive oxygen intermediates (ROI) in Kupffer cells isolated from livers of zymosan-treated rats, have been studied. ROI production was low in normal Kupffer cells but increased 18-fold by LPS in Kupffer cells from zymosan-treated rats. However, preincubation of LPS with rat serum, low density lipoproteins, high density lipoproteins (HDL3) and apolipoprotein A-I (apoA-I) decreased the LPS-induced production of ROI by 1.2-, 1.3-, 2.8-, and 1.5-fold, respectively. In contrast, very low density lipoproteins and HDL2 had no significant effect on the LPS-induced production of ROI. These results provide evidence for LPS-HDL3 complex formation and suggest that HDL3 and apoA-I play an important role in host defense against endotoxemia and infection.
