Ebola & Marburg Virus

Ebola virus disease (EVD) is a severe and frequently lethal disease caused by Ebola virus (EBOV). EVD outbreaks typically start from a single case of probable zoonotic transmission, followed by human-to-human transmission via direct contact or contact with infected bodily fluids or contaminated fomites. EVD has a high case–fatality rate; it is characterized by fever, gastrointestinal signs and multiple organ dysfunction syndrome.(1) antibodies-online supports research on EBOV and MARV with a wide range of high-quality antibodies, proteins, lysates.

Ebola virus is one of the most virulent pathogens known to infect humans. The first recognized Ebola outbreak occurred in 1976, near the Ebola River in Zaire (now Democratic Republic of Congo, DRC). Over the past 40 years, more than 20 outbreaks have occurred in Africa, with most of the known outbreaks occurring in the past 20 years.(3)

Marburgvirus (MARV) is closely related to the better-known Ebola virus and causes a similarly severe disease in humans. Some of the unique characteristics of filovirus outbreaks were reported for MARV disease (MVD) long before they were noticed in EBOV disease. (8) A likely natural host for MARV and RAVV, and the probable source of the highly infectious viruses that cause Marburg virus disease (MVD) in humans, is the Egyptian fruit bat (Rousettus aegyptiacus).(9)

Marburg virus and Ebola virus belong to the family Filoviridae. To date, 12 distinct filoviruses have been described. The seven filoviruses that have been found in humans belong either to the genus Ebolavirus (Bundibugyo virus (BDBV), Ebola virus (EBOV), Reston virus (RESTV), Sudan virus (SUDV) and Taï Forest virus (TAFV)) or to the genus Marburgvirus (Marburg virus (MARV) and Ravn virus (RAVV))(Fig 1). The WHO International Classification of Diseases Revision 11 of 2018 recognizes two major subcategories of filovirus disease (FVD): Ebola disease caused by BDBV, EBOV, SUDV or TAFV, and Marburg disease caused by MARV or RAVV.(1)

Before 2014, almost all Ebola pipeline candidates were at the pre-clinical stage. Today, following a coordinated global effort, there are active pipelines for diagnostics, drugs and vaccines, with multiple candidates in late-stage clinical development. In 2018, the WHO approved five experimental therapies – three monoclonal antibodies (ZMapp, mAb114 and REGN-EB3) and two antiviral drugs (remdesivir and favipiravir) – for the treatment of Ebola under the MEURI protocol (adopted for the first time ever).(4) The first-ever multi-drug trial investigating the efficacy of these drugs (other than favipiravir) began in 2018.(5)(6) In 2019, mAb114 and REGN-EB3 were deemed superior to ZMapp and both received Breakthrough Therapy designation from the FDA.(5)(6) Despite this success, there remains an unmet need for a therapeutic agent with pan-filovirus efficacy.(7)

Genome Organization of Ebola Virus and Marburg Virus

The 19 kb viral genome encodes for seven main proteins: nucleoprotein (NP), glycoprotein (GP), L-polymerase (L) protein, viral protein (VP) 24, VP30, VP35, and VP40 (Fig 2). L is an RNA-dependent RNA polymerase (RdRp) and forms the RdRp complex with VP30 that is responsible for viral genome transcription and replication. VP24 and VP35 inhibit interferon signalling and facilitate evasion of the host immune response. NP encapsidates the viral genome into the nucleocapsid, whilst VP40 drives viral assembly and budding. GP is the only protein on the surface of the virion and is essential for binding to target cells and subsequently mediating membrane fusion and the release of the viral genome.(11)
