NPC1 and infection: To determine how EBOV infection might influence the NPC1 receptor expression levels, we selected cell isolates from M. condylurus with different NPC1 basic expression levels (MoLu Prim, MoBra Prim, and MoKi) and assessed the changes of NPC1 receptor expression levels 22 days post-infection with EBOV using confocal microscopy (Supplementary Figure S3).
