Filovirus receptor NPC1 contributes to species-specific patterns of ebolavirus susceptibility in bats

eLife, 2015
Biological factors that influence the host range and spillover of Ebola virus (EBOV) and other filoviruses remain enigmatic. While filoviruses infect diverse mammalian cell lines, we report that cells from African straw-colored fruit bats (Eidolon helvum)

Filovirus assembly and budding

Virology, 2006
Filoviruses belong to the order of negative-stranded non-segmented RNA viruses and are classified into two genera, Ebola and Marburg viruses. They have a characteristic filamentous shape, which is largely determined by the matrix protein VP40. Although VP40 is the main driving force for assembly and budding from the host cell, the production of ...

A Multi-Filovirus Vaccine Candidate: Co-Expression of Ebola, Sudan, and Marburg Antigens in a Single Vector

Vaccines, 2020
In the infectious diseases field, protective immunity against individual virus species or strains does not always confer cross-reactive immunity to closely related viruses, leaving individuals susceptible to disease after exposure to related virus ...

Niemann-Pick C1 (NPC1)/NPC1-like1 Chimeras Define Sequences Critical for NPC1’s Function as a Filovirus Entry Receptor

Viruses, 2012
We recently demonstrated that Niemann-Pick C1 (NPC1), a ubiquitous 13-pass cellular membrane protein involved in lysosomal cholesterol transport, is a critical entry receptor for filoviruses.

Endocytic Pathways Involved in Filovirus Entry: Advances, Implications and Future Directions

Viruses, 2012
Detailed knowledge of the host-virus interactions that accompany filovirus entry into cells is expected to identify determinants of viral virulence and host range, and to yield targets for the development of antiviral therapeutics.

A retrospective cohort investigation of seroprevalence of Marburg virus and ebolaviruses in two different ecological zones in Uganda

BMC Infectious Diseases, 2020
Background Uganda has experienced seven Ebola Virus Disease (EVD) outbreaks and four Marburg Virus Disease (MVD) outbreaks between 2000 and 2019. We investigated the seroprevalence and risk factors for Marburg virus and ebolaviruses in gold mining ...

Antibody-Dependent Enhancement of Ebola Virus Infection by Human Antibodies Isolated from Survivors

Cell Reports, 2018
Summary: Some monoclonal antibodies (mAbs) recovered from survivors of filovirus infections can protect against infection. It is currently unknown whether natural infection also induces some antibodies with the capacity for antibody-dependent enhancement

Assembly and transport of filovirus nucleocapsids

PLOS Pathogens, 2022
Filovirus-infected cells are characterized by typical cytoplasmic inclusion bodies (IBs) located in the perinuclear region. The formation of these IBs is induced mainly by the accumulation of the filoviral nucleoprotein NP, which recruits the other nucleocapsid proteins, the polymerase co-factor VP35, the polymerase L, the transcription factor VP30 and

Durability of a vesicular stomatitis virus-based marburg virus vaccine in nonhuman primates.

PLoS ONE, 2014
The filoviruses, Marburg virus (MARV) and Ebola virus, causes severe hemorrhagic fever with high mortality in humans and nonhuman primates. A promising filovirus vaccine under development is based on a recombinant vesicular stomatitis virus (rVSV) that ...

Filovirus Replication and Transcription [PDF]

Future Virology, 2007
The highly pathogenic filoviruses, Marburg and Ebola virus, belong to the nonsegmented negative-sense RNA viruses of the order Mononegavirales. The mode of replication and transcription is similar for these viruses. On one hand, the negative-sense RNA genome serves as a template for replication, to generate progeny genomes, and, on the other hand, for ...
