However, the white FI reflecting Lep-vesicle-recycling endosome-exocyst-SNARE complexes in the infected HUVEC, EOMA, BJ, HK-2 or TCMK-1 cells showed a slight decrease at 24 hr post-infection, but the FI in the infected mouse fibroblasts (NIH/3T3) continued to increase (Figure 5C and F). Here, LEP is linked to infection.
