摘要:
Macrophage autophagy contributes to the hydrolysis of cholesteryl ester into free cholesterol mainly for ATP-binding cassette transporter A1 (ABCA1)-dependent efflux. Interferon-stimulated gene 15 (ISG15) has been shown to regulate autophagy in multiple types of cells. The present study aimed to examine the effects of ISG15 on autophagy and cholesterol efflux in THP-1 macrophage-derived foam cells and to explore the underlying molecular mechanisms. Our results showed that overexpression of ISG15 promoted autophagy and cholesterol efflux and inhibited lipid accumulation without impact on ABCA1 ...
