For infection experiments with EBOV we selected three primary and one immortalized M. condylurus cell types with a spectrum of NPC1 expression levels: MoTra Prim and MoSp Prim cells represented low NPC1 expression; MoHe Prim and MoKi cells represented moderate NPC1 expression, with clearly higher NPC1 expression in MoKi cells (Table 2). Here, NPC1 is linked to infection.
