- summary: Cell Host Microbe Broad-spectrum inhibition of retroviral and filoviral particle release by tetherin Tetherin-mediated restriction of filovirus budding is antagonized by the Ebola glycoprotein The Ebola virus glycoprotein and HIV-1 Vpu employ different strategies to counteract the antiviral factor tetherin The GP-protein of Marburg virus contains the region similar to the 'immunosuppressive domain' of oncogenic retrovirus P15E proteins Implication of a retrovirus-like glycoprotein peptide in the immunopathogenesis of Ebola and Marburg viruses Ectodomain shedding of the glycoprotein GP of Ebola virus Sorting of Marburg virus surface protein and virus release take place at opposite surfaces of infected polarized epithelial cells Interactions with the host cell Tsg101

- summary: Because the original complete sets of FDA approved compounds screened are not publically accessible it is difficult to compare hit rates versus all compounds tested to date. This pharmacophore (with an added van der Waals surface to limit the number of hits retrieved) was then used to screen and score other FDA drugs from score particularly well in terms of docking to VP35.

- summary: The viral glycoprotein (GP) facilitates host cell entry and, jointly with cellular interaction partners, constitutes a potential target for antiviral intervention. Here, we show that the GPs of the EBOVs circulating in 1976 and 2014 transduce the same spectrum of target cells, use the same cellular factors for host cell entry, and are comparably susceptible to blockade by antiviral interferon-induced transmembrane proteins and neutralizing antibody KZ52.

We discuss here the different aspects of the immune assays currently used in the Phase I clinical trials for Ebola virus vaccines, and draw comparisons across the immune outputs where possible; various trials have examined both cellular and humoral immunity in European and African cohorts.

To put the titers obtained after immunization of rabbits in a clinically relevant context, total anti-EBOV antibodies were quantified in a validated whole-virion EBOV antibody capture enzyme-linked immunosorbent assay (ELISA), used to assess the antibody responses in survivors of EBOV virus disease during the West African outbreak, 37 as well as a virus neutralization assay (VNT) with EBOV Zaire strain Mayinga used to assess antibody responses in VSVΔG/EBOV-GP vaccinated volunteers using the same assay.

- summary: [3] In their final remarks, Sidwell et al. (1972) stated, rightfully that the antiviral spectrum of Virazole was the broadest ever reported for any syntheticm aterial that does not induce interferon, although the eventual clinicalu se of Virazole would eventually be limited to RNA virus infections. That T-705 (Favipiravir), as av iral RNA polymerase inhibitor, offers great potential in the treatment of aw idev ariety of RNA virus infections, has been reviewed repeatedly.

- summary: Rather, we used a diverse set of bat NPC1 sequences, only one of which is from African straw-colored fruit bats, to show that a number of codons, including residue 502, have evolved under recurrent positive selection. In this study, we uncover a pattern of virus and host species specificity in the filovirus susceptibility of bat cells, which can be explained by eLife digest Ebola virus and other filoviruses can cause devastating diseases in humans and other apes.
