Abstract
AY-9944 and other cationic amphiphilic drugs (CADs) have been reported to cause a reduction of acid sphingomyelinase activity in fibroblasts and various tissues in the rat, and DMSO has been known to correct a partial deficiency of acid sphingomyelinase activity in Niemann-Pick type C (NPC) fibroblasts. Furthermore, in the present study we demonstrated that AY-9944 and other CADs caused a marked reduction of cholesterol esterification in control fibroblasts and an excessive intracellular accumulation of unesterified cholesterol as in NPC cells, and that this reduction could partially be corrected by the addition of 2% DMSO to the medium. These characteristics of the drug-treated cells mimic the phenomena seen in NPC fibroblasts. Therefore, fibroblasts treated with CADs may be used as a model of drug-induced lipidosis of NPC. The effect of DMSO suggests the possibility of its usefulness in the treatment of NPC patients.

Abstract
Biochemical and cytochemical studies have revealed that abnormal processing of low-density-lipoprotein (LDL) cholesterol can be reversed in mutant Niemann-Pick C (NP-C) fibroblasts when 2% dimethyl sulfoxide (DMSO) is added to the culture medium. Both the excessive lysosomal accumulation of LDL cholesterol and the delayed induction of cellular homeostatic responses associated with the uptake of LDL by the mutant cells were substantially reversed by DMSO. DMSO appears to accelerate the intracellular mobilization of LDL-derived cholesterol through effects that may reflect enhanced membrane permeability or cholesterol solubilization.
