| Chromatography Summary: | UHPLC-MS metabolomics analyses were performed using a Vanquish UHPLC system coupled online to a Q Exactive mass spectrometer (Thermo Fisher, Bremen, Germany). 20uL of supernatant was injected for plasma and CSF samples, and 10uL of supernatant was injected for cell samples. Samples were resolved over a Kinetex C18 column (2.1x150 mm, 1.7μm; Phenomenex, Torrance, CA, USA) at 45°C using a 5-minute gradient at 450μL/minute from 5-95% B (A: water/0.1% formic acid; B: acetonitrile/0.1% formic acid) for positive mode. To monitor possible technical variability, aliquots of each of the individual samples were combined to make technical replicates, which were run after every 15 samples. Additionally, in each experiment, several lysis solution aliquots were run as blanks for artifact identification. |

Samples were resolved over a Kinetex C18 column (2.1x150 mm, 1.7μm; Phenomenex, Torrance, CA, USA) at 45°C using a 5-minute gradient at 450μL/minute from 0-100% B (A: 95% water/5% acetonitrile, 1mM NH4OAc; B: 95% acetonitrile/5% water, 1mM NH4OAc) for negative mode. To monitor possible technical variability, aliquots of each of the individual samples were combined to make technical replicates, which were run after every 15 samples.
