Stages of phagocytosis in platelets’ internalization of influenza. Phagocytic morphological features of influenza internalization by platelets was assessed by TEM. a Representative images of different stages of phagosome-like structures assessed by morphological features captured in platelets from healthy human donors incubated with WSN/33 influenza (1 pfu to 10 platelets) at different time points. Five distinct stages can be observed in human platelets. b TEM of the negative stain of influenza virus (only)
