Phospholipid content in alveolar lavage fluid from wild type and PLA2G15 knockout mice.
| Lipid | Lipid level (nmol/mg protein) by phenotype |
|
|---|---|---|
| PLA2G15+/+ | PLA2G15−/− | |
| Phosphatidylcholine | 283 | 538 |
| 16:0 Phosphatidylcholine | 184 | 374 |
| Lysophosphatidylcholine | 1.2 | 2.3 |
| Phosphatidylethanolamine | 250 | 524 |
| Plasmalogen phosphatidylethanolamines | 173 | 414 |
| Sphingomyelin | 87.4 | 76.0 |
| Phosphatidic acid | 0.74 | 0.26 |
| Phosphatidylglycerol | 79.8 | 129.0 |
| Ceramide | 1.87 | 2.24 |
| Free fatty acid | 124 | 155 |
Lipid levels are derived from pooled samples of six 12 month-old mice (three male and three female) from each group. 16:0 designates the presence of palmitoyl containing phosphatidylcholine (35).
