Immunopathogenesis of atherosclerosis: endotoxin accelerates atherosclerosis in rabbits on hypercholesterolemic diet.
2001
Background—On the basis of our concept that atherosclerosis has an immunopathological background, we tested whether activation of the innate immune system influences its progression.Methods and Results—Hypercholesterolemic (0.5% wt/wt diet) rabbits received either repeated intravenous injections of endotoxin (Escherichia colilipopolysaccharide 1.25 to 2.5 μg, once per week) or a self-limiting cutaneousStaphylococcus aureusinfection with or without a quinolone antibiotic. Measured laboratory parameters, including LDL and HDL cholesterols, were similar in the different groups of hypercholesterolemic animals. All endotoxin-treated animals developed transient episodes of fever after endotoxin a…
Deficiency of bile acid transport and synthesis in oval cells from carcinogen-fed rats.
1994
Freshly isolated oval cells, which we obtained from the livers of rats fed a choline-deficient/DL-ethioninesupplemented diet, did not transport bile acids. Compared with freshly isolated rat hepatocytes they took up only negligible amounts of [3H]taurocholate or [14C]cholate. The cells bound small amounts of radioactive bile acids. This portion of the total cell-associated radioactivity was enhanced on membrane permeabilization. In contrast to cultured liver parenchymal cells from untreated rats, no bile acid synthesis was detected in cultured oval cells. Cultured oval cells also lost the ability to conjugate exogenously added cholate (100 μmol/L) with taurine or glycine. However, when live…
