TL;DR: Blood concentrations of two related oxysterols molecules were almost 10 times higher in Niemann-Pick C1 patients than in age-matched healthy controls or those with other diseases such as atherosclerosis or diabetes, suggesting that the two oxysterol molecules are accurate diagnostic markers of early clinical disease and can be used not only to monitor disease progression but also to demonstrate drug efficacy.

TL;DR: This open-label, dose-escalation phase 1-2a study gave monthly intrathecal HPβCD to participants with NPC1 with neurological manifestation at the National Institutes of Health and evaluated Serum and CSF 24(S)-hydroxycholesterol (24[S]-HC), which serves as a biomarker of target engagement, andCSF protein biomarkers were evaluated.

TL;DR: The development of a sensitive and specific LC-MS/MS method for quantifying 3β,5α,6β-triol and 7-KC human plasma after derivatization with N,N-dimethylglycine is described, offering for the first time a noninvasive, rapid, and highly sensitive method for diagnosis of NPC1 disease.

TL;DR: It is demonstrated that abnormal polarization in older macrophages is caused by programmatic changes that lead to reduced expression of ATP binding cassette transporter ABCA1, and this findings provide an avenue for therapeutic modulation of macrophage function in common age-related diseases.

TL;DR: It is shown that loss of three box C/D small nucleolar RNAs (snoRNAs) encoded in the ribosomal protein L13a (rpL13a) locus is sufficient to confer resistance to lipotoxic and oxidative stress in vitro and prevents the propagation of oxidative stressIn vivo.
