A lipidomic atlas of cells of the human and mouse immune systems

To test the hypothesis that the cellular lipidome would be a defining feature of the cells of the human immune system we isolated 16 distinct mature immune cell populations, representing all of the major immune cell lineages as well as numerous cell sub types.

Immune cells were isolated by fluorescence-activated cell sorting (FACS) from the peripheral blood of 14 healthy donors and their cellular lipidomes characterized by ultra-high-performance liquid chromatography coupled to tandem mass spectrometry (UHPLC ESI-MS/MS).

Human Immune Cell processing

To create a lipidomic atlas of the murine immune system, we used FACS to isolate 8 distinct immune cell types from the blood of C57BL6/J mice (male, 4-6 weeks of age, fed a standard laboratory mouse diet) and determined cellular lipid composition by mass spectrometry.
