DNM1 and infection: Inhibitors of dynamin (dynasore) and clathrin-mediated endocytosis (pitstop 2 and chlorpromazine; CPZ) exhibited no significant effect on SFTSV infection in HEK293AXL cells, although they reduced infection in HEK293DC-SIGN cells (Fig. 5B through D), suggesting that AXL-mediated entry does not rely on clathrin/dynamin-dependent pathways.
