PLA2G4A and infection: PPAR activation and cPLA2 inhibition decreased significantly 6k-PGF1α, PGE1, and PGF1α production (Supplementary Figure 4); however, PPARγ agonist was not able to reduce PGE2 production which increased significantly after infection (P < 0.001) at 60 and 120 min, respectively (Figure 5).
