| Study Title | Metabolomics of bone marrow-derived dendritic cells conditioned with H. polygyrus bakery non-polar metabolites |
| Study Summary | Bone marrow-derived dendritic cells were incubated with 50 micro g/mL of H. polygyrus bakery non-polar metabolites in RPMI 1640 containing 10% FBS, 1% of 100X penicillin/streptomycin, 1% of 100 mM sodium pyruvate, and 20 ng/mL GM-CSF at 37°C, 5% CO2 for 4 or 20 h. Supernatants and cell-free media controls were collected and incubated with ice-cold HPLC-grade methanol for 30 min on ice, centrifuged at 10,000 x g for 10 min at 4°C and stored at -80°C until analysis. The profiling of nonpolar metabolites was performed by LC-MS/MS analysis of the deproteinated conditioned media by injecting 3 mL of sample onto a Dionex UHPLC system equipped with an Agilent Eclipse C18 (2.1 x 15 mm, 1.8 mm) column incubated at 45oC. Metabolites were resolved with a 30 min linear running 0-80 % using the buffers system 0.05 % formic acid and 0.05 % formic acid in acetonitrile at a flowrate of 300 mL/min. The column effluent was introduced by electrospray ionization onto a ThermoScientific Velos LTQ Orbitrap Analyzer using a spray voltage of 3.6 kV, a source heater temperature of 350oC, and a sheath gas flow of 40 L/min. Survey scans were performed using the Orbitrap mass spectrometer and the 10 most intense ions were selected for fragmentation using a 30-40 V stepped collision induced dissociation energy. Fragmentation products were analyzed in the linear ion trap mass spectrometer. Fragmentation was used to perform XCMS online database (https://xcmsonline.scripps.edu) search to identify possible metabolites. |
