    Abstract The Malaysian strain of Nipah virus (NiV) first emerged in 1998/99 and caused a major disease outbreak in pigs and humans. While humans developed fatal encephalitis due to a prominent infection of brain microvessels, NiV-infected pigs mostly suffered from an acute respiratory disease and efficiently spread the infection via airway secretions. To elucidate the molecular basis of the highly productive NiV replication in porcine airways in vitro, physiologically relevant cell models that have maintained functional characteristics of airway epithelia in vivo are needed. Here, we describe in detail the method of isolating bronchial epithelial cells (PBEpC) from pig lungs that can be used for NiV infection studies. After the dissection of primary bronchia and removal of the mucus and protease digestion, bronchi segments are cut open and epithelial cells are scraped off and seeded on collagen-coated cell culture flasks. With this method, it is possible to isolate about 2 × 10

    Abstract During the Nipah virus (NiV) outbreak in Malaysia, pigs and humans were infected. While pigs generally developed severe respiratory disease due to effective virus replication and associated inflammation processes in porcine airways, respiratory symptoms in humans were rare and less severe. To elucidate the reasons for the species-specific differences in NiV airway infections, we compared the cytokine responses as a first reaction to NiV in primary porcine and human bronchial epithelial cells (PBEpC and HBEpC, respectively). In both cell types, NiV infection resulted in the expression of type III interferons (IFN-λ). Upon infection with similar virus doses, viral RNA load and IFN expression were substantially higher in HBEpC. Even if PBEpC expressed the same viral RNA amounts as NiV-infected HBEpC, the porcine cells showed reduced IFN- and IFN-dependent antiviral gene expression. Despite this inherently limited IFN response, the expression of proinflammatory cytokines (IL-6, IL-8) in NiV-infected PBEpC was not decreased. The downregulation of antiviral activity in the presence of a functional proinflammatory cytokine response might be one of the species-specific factors contributing to efficient virus replication and acute inflammation in the lungs of pigs infected with the Malaysian NiV strain.

    Abstract Nipah virus (NiV) matrix protein (NiV M) plays a major role in virus assembly. It undergoes nuclear transit before accumulating at the plasma membrane and recruiting nucleocapsids to the budding sites. Because nuclear NiV M cannot be detected in all cell types, we wondered whether it can reach the cell surface by bypassing the nucleus. Using an M mutant with a defective nuclear export signal (MNESmut), however, we revealed that the nuclear import of M is ubiquitous, because MNESmut was retained in the nuclei of all cell types tested. Because a functional nuclear transit is a general prerequisite for M surface transport, we wanted to characterize the effect of nuclear-retained M protein in a full viral context and generated a recombinant NiV-MNESmut. Mutant NiV-MNESmut caused increased cell-cell fusion and produced lower virus titers. As expected for an assembly defective NiV, perinuclear inclusions (IBperi) were formed, but inclusions at the plasma membrane (IBPM), which probably represent the viral assembly platforms, were not found. It is interesting to note that the transport-defective MNESmut was recruited to IBperi. This probably prevents overaccumulation of nonfunctional M proteins in the cytoplasm and nuclei of NiV-infected cells and thus provides first evidence that IBperi are functionally relevant aggresome-like compartments.

    Abstract The urgent need for vaccines against Ebola virus (EBOV) was underscored by the large outbreak in West Africa (2014-2016). Since then, several promising vaccine candidates have been tested in pre-clinical and clinical studies. As a result, two vaccines were approved for human use in 2019/2020, of which one includes a heterologous adenovirus/Modified Vaccinia virus Ankara (MVA) prime-boost regimen. Here, we tested new vaccine candidates based on the recombinant MVA vector, encoding the EBOV nucleoprotein (MVA-EBOV-NP) or glycoprotein (MVA-EBOV-GP) for their efficacy after homologous prime-boost immunization in mice. Our aim was to investigate the role of each antigen in terms of efficacy and correlates of protection. Sera of mice vaccinated with MVA-EBOV-GP were virus-neutralizing and MVA-EBOV-NP immunization readily elicited interferon-γ-producing NP-specific CD8+ T cells. While mock-vaccinated mice succumbed to EBOV infection, all vaccinated mice survived and showed drastically decreased viral loads in sera and organs. In addition, MVA-EBOV-NP vaccinated mice became susceptible to lethal EBOV infection after depletion of CD8+ T cells prior to challenge. This study highlights the potential of MVA-based vaccines to elicit humoral immune responses as well as a strong and protective CD8+ T cell response and contributes to understanding the possible underlying mechanisms.

    Abstract Acute kidney injury is associated with mortality in COVID-19 patients. However, host cell changes underlying infection of renal cells with SARS-CoV-2 remain unknown and prevent understanding of the molecular mechanisms that may contribute to renal pathology. Here, we carried out quantitative translatome and whole-cell proteomics analyses of primary renal proximal and distal tubular epithelial cells derived from human donors infected with SARS-CoV-2 or MERS-CoV to disseminate virus and cell type-specific changes over time. Our findings revealed shared pathways modified upon infection with both viruses, as well as SARS-CoV-2-specific host cell modulation driving key changes in innate immune activation and cellular protein quality control. Notably, MERS-CoV infection-induced specific changes in mitochondrial biology that were not observed in response to SARS-CoV-2 infection. Furthermore, we identified extensive modulation in pathways associated with kidney failure that changed in a virus- and cell type-specific manner. In summary, we provide an overview of the effects of SARS-CoV-2 or MERS-CoV infection on primary renal epithelial cells revealing key pathways that may be essential for viral replication.

    Abstract Emerging and re-emerging viruses, such as Zaire Ebola virus (EBOV), pose a global threat and require immediate countermeasures, including the rapid development of effective vaccines that are easy to manufacture. Synthetic self-amplifying RNAs (saRNAs) attend to these needs, being safe and strong immune stimulators that can be inexpensively produced in large quantities, using cell-free systems and good manufacturing practice. Here, the first goal was to develop and optimize an anti-EBOV saRNA-based vaccine in terms of its antigen composition and route of administration. Vaccinating mice with saRNAs expressing the EBOV glycoprotein (GP) alone or in combination with the nucleoprotein (NP) elicited antigen-specific immune responses. GP-specific antibodies showed neutralizing activity against EBOV. Strong CD4
