Influenza C virus contains two envelope glycoproteins: CM2, a putative ion channel protein; and HEF, a unique multifunctional protein that performs receptor-binding, receptor-destroying and fusion activities. Here, it is demonstrated that expression of HEF is sufficient to pseudotype replication-incompetent vesicular stomatitis virus (VSV) that lacks the VSV glycoprotein (G) gene. The pseudotyped virus showed characteristic features of influenza C virus with respect to proteolytic activation, receptor usage and cell tropism. Chimeric glycoproteins composed of HEF ectodomain and VSV-G C-terminal domains were efficiently incorporated into VSV particles and showed receptor-binding and receptor-destroying activities but, unlike authentic HEF, did not mediate efficient infection, probably because of impaired fusion activity. HEF-pseudotyped VSV efficiently infected polarized Madin–Darby canine kidney cells via the apical plasma membrane, whereas entry of VSV-G-complemented virus was restricted to the basolateral membrane. These findings suggest that pseudotyping of viral vectors with HEF might be useful for efficient apical gene transfer into polarized epithelial cells and for targeting cells that express 9-O-acetylated sialic acids.

The G protein of vesicular stomatitis virus, implanted into the apical plasma membrane of Madin-Darby canine kidney cells, is rapidly transcytosed to the basolateral membrane. In this and the accompanying paper (Pesonen, M., R. Bravo, and K. Simons, 1984, J. Cell Biol. 99:803-809.) we have studied the intracellular route by which the G protein traverses during transcytosis. Using Percoll density gradient centrifugation and free flow electrophoresis we could demonstrate that the G protein is endocytosed into a nonlysosomal compartment with a density of approximately 1.05 g/cm3, which has many of the characteristics of endosomes. Transcytosis to the basolateral membrane appeared to occur from this compartment. No direct evidence for the involvement of lysosomes in the transcytotic route could be obtained. No G protein was detected in the lysosomes when transcytosis of G protein was occurring. Moreover, at 21 degrees C when passage of G protein to the lysosomes was shown to be arrested, transcytosis of G protein could still be demonstrated.

ABSTRACT Ebola virus contains a single glycoprotein (GP) that is responsible for receptor binding and membrane fusion and is proteolytically cleaved into disulfide-linked GP1 and GP2 subunits. The GP2 subunit possesses a coiled-coil motif, which plays an important role in the oligomerization and fusion activity of other viral GPs. To determine the functional significance of the coiled-coil motif of GP2, we examined the effects of peptides corresponding to the coiled-coil motif of GP2 on the infectivity of a mutant vesicular stomatitis virus (lacking the receptor-binding/fusion protein) pseudotyped with the Ebola virus GP. A peptide corresponding to the C-terminal helix reduced the infectivity of the pseudotyped virus. We next introduced alanine substitutions into hydrophobic residues in the coiled-coil motif to identify residues important for GP function. None of the substitutions affected GP oligomerization, but some mutations, two in the N-terminal helix and all in the C-terminal helix, reduced the ability of GP to confer infectivity to the mutant vesicular stomatitis virus without affecting the transport of GP to the cell surface, its incorporation into virions, and the production of virus particles. These results indicate that the coiled-coil motif of GP2 plays an important role in facilitating the entry of Ebola virus into host cells and that peptides corresponding to this region could act as efficient antiviral agents.

Rab8 is a small Ras-like GTPase that regulates polarized membrane transport to the basolateral membrane in epithelial cells and to the dendrites in neurons. It has recently been demonstrated that fibroblasts sort newly synthesized proteins into two different pathways for delivery to the cell surface that are equivalent to the apical and the basolateral post-Golgi routes in epithelial cells (Yoshimori, T., P. Keller, M.G. Roth, and K. Simons. 1996. J. Cell Biol. 133:247-256). To determine the role of Rab8 in fibroblasts, we used both transient expression systems and stable cell lines expressing mutant or wild-type (wt) Rab8. A dramatic change in cell morphology occurred in BHK cells expressing both the wt Rab8 and the activated form of the GTPase, the Rab8Q67L mutant. These cells formed processes as a result of a reorganization of both their actin filaments and microtubules. Newly synthesized vesicular stomatitis virus G glycoprotein, a basolateral marker protein in MDCK cells, was preferentially delivered into these cell outgrowths. Based on these findings, we propose that Rab8 provides a link between the machinery responsible for the formation of cell protrusions and polarized biosynthetic membrane traffic.

ABSTRACT In polarized epithelial cells, the vesicular stomatitis virus glycoprotein is segregated to the basolateral plasma membrane, where budding of the virus takes place. We have generated recombinant viruses expressing mutant glycoproteins without the basolateral-membrane-targeting signal in the cytoplasmic domain. Though about 50% of the mutant glycoproteins were found at the apical plasma membranes of infected MDCK cells, the virus was still predominantly released at the basolateral membranes, indicating that factors other than the glycoprotein determine the site of virus budding.

Enveloped viruses can incorporate host cell membrane proteins during the budding process. Here we demonstrate that mumps virus (MuV) and vesicular stomatitis virus (VSV) assemble to include CD46 and CD55, two host cell regulators which inhibit propagation of complement pathways through distinct mechanisms. Using viruses which incorporated CD46 alone, CD55 alone, or both CD46 and CD55, we have tested the relative contribution of these regulators in resistance to complement-mediated neutralization. Virion-associated CD46 and CD55 were biologically active, with VSV showing higher levels of activity of both cofactors, which promoted factor I-mediated cleavage of C3b into iC3b as well as decay-accelerating factor (DAF) activity against the C3 convertase, than MuV. Time courses ofin vitroneutralization with normal human serum (NHS) showed that both regulators could delay neutralization, but viruses containing CD46 alone were neutralized faster and more completely than viruses containing CD55 alone. A dominant inhibitory role for CD55 was most evident for VSV, where virus containing CD55 alone was not substantially different in neutralization kinetics from virus harboring both regulators. Electron microscopy showed that VSV neutralization proceeded through virion aggregation followed by lysis, with virion-associated CD55 providing a delay in both aggregation and lysis more substantial than that conferred by CD46. Our results demonstrate the functional significance of incorporation of host cell factors during virion envelope assembly. They also define pathways of virus complement-mediated neutralization and suggest the design of more effective viral vectors.

ABSTRACT The Autographa californica multiple nucleopolyhedrovirus (AcMNPV) GP64 protein is an essential virion protein that is involved in both receptor binding and membrane fusion during viral entry. Genetic studies have shown that GP64-null viruses are unable to move from cell to cell and this results from a defect in the assembly and production of budded virions (BV). To further examine requirements for virion budding, we asked whether a GP64-null baculovirus, vAc64−, could be pseudotyped by introducing a heterologous viral envelope protein (vesicular stomatitis virus G protein [VSV-G]) into its membrane and whether the resulting virus was infectious. To address this question, we generated a stably transfected insect Sf9 cell line (Sf9VSV-G) that inducibly expresses the VSV-G protein upon infection with AcMNPV Sf9VSV-G and Sf9 cells were infected with vAc64−, and cells were monitored for infection and for movement of infection from cell to cell. vAc64− formed plaques on Sf9VSV-G cells but not on Sf9 cells, and plaques formed on Sf9VSV-G cells were observed only after prolonged intervals. Passage and amplification of vAc64− on Sf9VSV-G cells resulted in pseudotyped virus particles that contained the VSV-G protein. Cell-to-cell propagation of vAc64− in the G-expressing cells was delayed in comparison to wild-type (wt) AcMNPV, and growth curves showed that pseudotyped vAc64− was generated at titers of approximately 106 to 107 infectious units (IU)/ml, compared with titers of approximately 108 IU/ml for wt AcMNPV. Propagation and amplification of pseudotyped vAc64− virions in Sf9VSV-G cells suggests that the VSV-G protein may either possess the signals necessary for baculovirus BV assembly and budding at the cell surface or may otherwise facilitate production of infectious baculovirus virions. The functional complementation of GP64-null viruses by VSV-G protein was further demonstrated by identification of a vAc64−-derived virus that had acquired the G gene through recombination with Sf9VSV-G cellular DNA. GP64-null viruses expressing the VSV-G gene were capable of productive infection, replication, and propagation in Sf9 cells.

In the preceding paper (Pesonen M., W. Ansorge, and K. Simons, 1984, J. Cell Biol., 99:796-802), we have shown that transcellular transport of the membrane glycoprotein G of vesicular stomatitis virus implanted into the apical membrane of Madin-Darby canine kidney cells is transcytosed through the endosomal compartment to the basolateral plasma membrane. To determine whether the Golgi complex was involved in this process, G protein lacking sialic acid or all of the terminal sugars was implanted into the apical membrane and allowed to move to the basolateral membrane. Using the criteria of endoglycosidase H sensitivity, binding to Ricinus communis agglutinin and two-dimensional gel electrophoresis, the sugars on the transcytosed G protein were found to be the same as in the starting material. The absence of any involvement of the Golgi complex in transcytosis was supported by subcellular fractionation studies in which transcytosing G protein was never found in fractions containing galactosyl transferase.

World Health Organization (WHO) has prioritized the infectious emerging diseases such as Coronavirus Disease (COVID-19) in terms of research and development of effective tests, vaccines, antivirals, and other treatments. Severe Acute Respiratory Syndrome-Coronavirus-2 (SARS-CoV-2), the etiological causative agent of COVID-19, is a virus belonging to risk group 3 that requires Biosafety Level (BSL)-3 laboratories and the corresponding facilities for handling. An alternative to these BSL-3/-4 laboratories is to use a pseudotyped virus that can be handled in a BSL-2 laboratory for study purposes. Recombinant Vesicular Stomatitis Virus (VSV) can be generated with complementary DNA from complete negative-stranded genomic RNA, with deleted G glycoprotein and, instead, incorporation of other fusion protein, like SARS-CoV-2 Spike (S protein). Accordingly, it is called pseudotyped VSV-SARS-CoV-2 S. In this review, we have described the generation of pseudotyped VSV with a focus on the optimization and application of pseudotyped VSV-SARS-CoV-2 S. The application of this pseudovirus has been addressed by its use in neutralizing antibody assays in order to evaluate a new vaccine, emergent SARS-CoV-2 variants (delta and omicron), and approved vaccine efficacy against variants of concern as well as in viral fusion-focused treatment analysis that can be performed under BSL-2 conditions.

Using monoclonal antibodies and indirect immunofluorescence microscopy, we investigated the distribution of the M protein in situ in vesicular stomatitis virus-(VSV) infected MDCK cells. M protein was observed free in the cytoplasm and associated with the plasma membrane. Using the ts045 mutant of VSV to uncouple the synthesis and transport of the VSV G protein we demonstrated that this distribution was not related to the presence of G protein on the cell surface. Sections of epon-embedded infected cells labeled with antibody to the M protein and processed for indirect horseradish peroxidase immunocytochemistry revealed that the M protein was associated specifically with the basolateral plasma membrane. The G and M proteins of VSV have therefore evolved features which bring them independently to the basolateral membrane of polarized epithelial cells and allow virus to bud specifically from that membrane.
