PLA2G4A and infection: To further confirm the above results, inhibition of cPla2 at 24 hpi, to allow the recruitment of neutrophils to the infection site, mimicked the effects of Ptgs inhibition (Fig. 8f and Supplementary Fig. 12D), while inhibition of Ptgs1/2 (Fig. 8g) and Ptgs2 (Supplementary Fig. 12E) or exogenous addition of AA (Supplementary Fig. 13B) at 24 hpi rescued the resistance of Gbp4-deficient larvae but had no effect on their WT siblings.
