	1	Lysosomal cholesterol accumulation is commonly found in most peroxisomal disorders and reversed by 2-hydroxypropyl-β-cyclodextrin显示文摘Peroxisomal disorders(PDs)are a heterogenous group of diseases caused by defects in peroxisome biogenesis or functions.Xlinked adrenoleukodystrophy is the most prevalent form of PDs and results from mutations in the ABCD1 gene,which encodes a transporter mediating the uptake of very long-chain fatty acids(VLCFAs).The curative approaches for PDs are very limited.Here,we investigated whether cholesterol accumulation in the lysosomes is a biochemical feature shared by a broad spectrum of PDs.We individually knocked down fifteen PD-associated genes in cultured cells and found ten induced cholesterol accumulation in the lysosome.2-Hydroxypropyl-β-cyclodextrin(HPCD)effectively alleviated the cholesterol accumulation phenotype in PD-mimicking cells through reducing intracellular cholesterol content as well as promoting cholesterol redistribution to other cellular membranes.In ABCD1 knockdown cells,HPCD treatment lowered reactive oxygen species and VLCFA to normal levels.In Abcd1 knockout mice,HPCD injections reduced cholesterol and VLCFA sequestration in the brain and adrenal cortex.The plasma levels of adrenocortical hormones were increased and the behavioral abnormalities were greatly ameliorated upon HPCD administration.Together,our results suggest that defective cholesterol transport underlies most,if not all,PDs,and that HPCD can serve as a novel and effective strategy for the treatment of PDs.
