ILC2 transfers to apolipoprotein E deficient mice reduce the lipid content of atherosclerotic lesions.

ABSTRACT: BACKGROUND:Expansion of type 2 innate lymphoid cells (ILC2s) in hypercholesterolaemic mice protects against atherosclerosis while different ILC2 subsets have been described (natural, inflammatory) based on their suppression of tumorigenicity 2 (ST2) and killer-cell lectin like receptor G1 (KLRG1) expression. The aim of the current study is to characterize the interleukin 25 (IL25)-induced splenic ILC2 population (Lin-CD45+IL17RB+ICOS+IL7raintermediate) and address its direct role in experimental atherosclerosis by its adoptive transfer to hypercholesterolaemic apolipoprotein E deficient (apoE-/-) mice. RESULTS:Immunomagnetically enriched, FACS-sorted ILC2s from the spleens of IL-25 treated apoE-/- mice were stained for KLRG1 and ST2 directly upon cell obtainment or in vitro cell expansion
