Human macrophages infected with Egyptian Rousette bat-isolated Marburg virus display inter-individual susceptibility and antiviral responsiveness.

ABSTRACT: Marburg virus (MARV) is a highly pathogenic filovirus and a causative agent of sporadic zoonotic viral hemorrhagic fever outbreaks with high case fatality rates. In humans, filoviruses like MARV and Zaire Ebola virus (EBOV) target, among others, innate immune cells like dendritic cells and macrophages (MΦs). Filovirus-infected dendritic cells display impaired maturation and antigen presentation, while MΦs become hyper-activated and secrete proinflammatory cytokines and chemokines. Our current understanding of human macrophage responses to MARV remains limited. Here, we used human monocyte-derived macrophages (moMΦs) to address how their phenotype, transcriptional profile, and protein expression change upon an in vitro infection with a bat isolate of MARV. Confirming its tropism for macroph
