In vitro phagocytosis of platelets and the influence of oseltamivir. Stimulated THP-1 cells were incubated with platelets. a Control response. b Patients’ response. c Phagocytosis rates of the PT patients, HSCT controls, and PT patients with DANA. Platelets from the healthy controls were treated with Neu to provide a positive control. d Effects of different concentrations of oseltamivir on sialidase activity on the platelet surface. e Effects of different concentrations of oseltamivir on the phagocytosis of platelets. f Effects of different concentrations of dexamethasone on the phagocytosis of platelets. The concentration of DANA is 1 mmol/L
