Significant changes in polyunsaturated fatty acid containing PC, PE, PI, and LPC species, and arachidonic acid to decosahexaenoic acid ratio for the same species in the hippocampus of repetitive mTBI hTau mice. Sample size for all groups across all time points is n = 4. All data represent mean μM per (5.5 mg) wet weight ±SEM. Individual molecular lipid species were quantified by liquid chromatography/mass spectrometry and were summed after LipidomeDB analyses to generate polyunsaturated fatty acid classification for each phospholipid species, and a ratio of arachidonic acid to decosahexaenoic acid was compiled from these values. Asterisks represent +P < 0.01 for comparisons between sham/r-mTBI mice. PE, phosphatidylethanolamine; PC, phosphatidylcholine; LPC, lysophosphatidylcholine; PI, phosphatidylinositol; AA, arachidonic acid; DHA, decosahexaenoic acid.
