CD36 and infection: To determine whether the CD36 molecules were platelet derived, we performed a sandwich enzyme-linked immunosorbent assay (ELISA) with exosomes from pooled mice plasma and observed increased levels of CD36–CD41 double-positive particles in the exosome fraction from post-infection days 5 and 8 (Figure 3C), suggesting that some CD36-positive exosomes were released from platelets in the parasitized mice.
