In the present study, we used infection with the gram-negative bacterium, Salmonella enterica serovar Typhimurium (S.tm) to study the involvement of BAT in infection-induced fever and employed APOE∗3-Leiden.CETP transgenic mice as a well-established model of human-like lipoprotein metabolism (9) to investigate the consequences of bacteremia for lipid metabolism. This evidence concerns the gene CETP and infection.
