Impact of inducing hypercholesterolemia on Kupffer cells

Kupffer cells (KCs) are the largest tissue resident macrophage population in direct contact with blood and thus with circulating lipoproteins. How KCs homeostasis is affected by the build-up of cholesterol-rich lipoproteins in the context of hypercholesterolemia has been poorly investigated. In this study, 5-month-old LDL receptor deficient (C57BL6J background) male mice were subjected to chow diet or a cholesterol-rich (HC) diet for four days to induce hypercholesterolemia. RNA sequencing was then performed on cell sorted KCs.
