TLDR
Treatment of NP-C2 fibroblasts with exogenous recombinant HE1 protein ameliorated lysosomal accumulation of low density lipoprotein-derived cholesterol.Abstract:
Niemann-Pick type C2 disease (NP-C2) is a fatal hereditary disorder of unknown etiology characterized by defective egress of cholesterol from lysosomes. Here we show that the disease is caused by a deficiency in HE1, a ubiquitously expressed lysosomal protein identified previously as a cholesterol-binding protein. HE1 was undetectable in fibroblasts from NP-C2 patients but present in fibroblasts from unaffected controls and NP-C1 patients. Mutations in the HE1 gene, which maps to chromosome 14q24.3, were found in NP-C2 patients but not in controls. Treatment of NP-C2 fibroblasts with exogenous recombinant HE1 protein ameliorated lysosomal accumulation of low density lipoprotein-derived cholesterol.read more

Cellular cholesterol, membrane signaling, and disease
TL;DR: This chapter describes the hereditary disorders that provide unique systems for genetic manipulation of rafts and a potential opportunity to disrupt raft-dependent signaling in the whole animal and provides a more detailed analysis of the wider roles of cholesterol in signaling and the relationships between signaling and membrane trafficking.

Anti-npc2 monoclonal antibodies and a method of detecting fatty liver tissue, cancer cells or cancer tissue by using them
TL;DR: In this article, anti-NPC2 monoclonal antibodies against NPC2 or glycosylated NPC2 were used to detect fatty liver tissues, cancer cells or cancer tissues by evaluating the expression level of NPC2 in the cells or tissues.

Niemann–Pick C1 Is a Late Endosome-Resident Protein That Transiently Associates with Lysosomes and the Trans-Golgi Network
TL;DR: Characterizing the subcellular location of the NPC1 protein suggests that U18666A may inhibit the retrograde transport of NPC1 from lysosomes to late endosomes for subsequent transfer to the trans-Golgi network.
