| Research Abstract |
We functionally analyzed ACAT1-positive late endosomes (ACAT1-LE) which appears in cholesterol-rich macrophages. ACAT1-LE contributed effective cholesterol esterification, in addition, they showed impaired phagosomal maturation. Interestingly, such impairment partially correlated by pharmacological inhibition of cholesterol esterification.
