Figure 3. The Biosynthetic Pathways for Eicosanoids and Specialized Pro-Resolution Lipid Mediators (SPM).
The C1P/cPLA2α interaction at cellular membranes releases sn2 bound unsaturated fatty acids (AA, EPA, DHA) from membrane-bound phospholipids. Through interactions with cyclooxygenases, cytochrome P450, or lipoxygenases; AA, DHA, and EPA are converted into pro-inflammatory (red) or anti-inflammatory (green) lipid mediators.
