Fig. 6. CD facilitates RCT in vivo and promotes urinary cholesterol excretion. CD facilitates RCT in vivo and promotes urinary cholesterol excretion. (A) BMDMs from WT or LXRα−/−β−/− mice were loaded with 100 μg of D6-CC per 1 × 106 cells and injected into the peritoneum of WT mice. Subsequently, mice were treated subcutaneously with CD (2 g kg) or vehicle control (n = 4 per group). (B and C) D6-cholesterol content in feces and urine collected every 3 hours over 30 hours after CD injection. Data are shown as total area under the curve (AUC) of excreted D6-cholesterol pooled from the mice within a group per time point. (D) Urine samples collected from three individual NPC1 patients upon intravenous application of CD for specific treatment of NPC. Urine cholesterol concentration was determined by GC-MS-SIM and normalized to urine creatinine excretion. Sebastian Zimmer et al., Sci Transl Med 2016;8:333ra50 Published by AAAS
