APOE and infection: First, and as expected, SD-SSU:SCG5 transgenic parasites expressing a ‘null-scGal’ LPG PAMP survived poorly following blood meal excretion, with a 81–92% decrease in mean parasite numbers relative to control FV1-infected flies (p<0.0005), and 38–40% of PpapJ flies having lost their infections (Fig. 2A,B, “no blood, d5”).
