Persimmon tannin promoted macrophage reverse cholesterol transport through inhibiting ERK1/2 and activating PPARγ both in vitro and in vivo

Abstract The purpose of this study was to investigate whether persimmon tannin is associated with cholesterol efflux and macrophage-reverse cholesterol transport (RCT). In J774A.1 macrophage cells, persimmon tannin could inhibit cellular cholesterol accumulation and promote 22-NBD-cholesterol efflux through inhibiting the phosphorylation of ERK1/2 and up-regulating the protein levels of PPARγ. Macrophage RCT in vivo was evaluated by injecting 22-NBD-cholesterol-loaded J774A.1 macrophages intraperitoneally into C57BL/6J mice. Administration of persimmon tannin significantly (P
