FIGURE 6.
Arachidonic acid and docosahexaenoic acid containing phospholipid species in the hippocampus of repetitive mTBI hTau mice. Significant changes in arachidonic acid and docosahexaenoic acid containing PI (A,B), PE (C,D), PC (E,F), and LPC (G,H) species in the hippocampus of a model of repetitive-mTBI in hTau mice. Sample size for all groups across all time points is n = 4. Data represent mean μmol per wet weight (5.5 mg) ±SEM. Individual molecular lipid species were quantified by liquid chromatography/mass spectrometry and were summed after LipidomeDB analyses to generate arachidonic and decosahexaenoic acid levels for each phospholipid species. Asterisks represent +P < 0.05, ++P < 0.01, +++P < 0.001 for comparisons between sham/r-mTBI mice. PE, phosphatidylethanolamine; PC, phosphatidylcholine; PI, phosphatidylinositol; LPC, lysophosphatidylcholine.
