Chronic alcohol ingestion modulates hepatic macrophage populations and functions in mice.

ABSTRACT: Hepatic Macs, consisting of resident KCs and infiltrating monocytes/IMs, are thought to play an important role in the pathogenesis of ALD. Previous work has focused on KCs or studied hepatic Macs as one cell population. The aim of the current study is to distinguish IMs from KCs and to compare their phenotypes and functions. We show here that a 4-week ethanol feeding of C57BL/6J mice causes recruitment of IMs into the liver. KCs and IMs can be distinguished based on their differential expression of F4/80 and CD11b. IMs can be divided further into two subsets based on their differential expression of Ly6C. KCs and two subsets of IMs were separately purified by FACS. The phagocytosis abilities and the expression profiles of genes related to various functions were compared among different pop
