We investigated a 73-kDa polypeptide (p73), a minor component of the rabies virion (HEP-Flury and ERA strains), accounting for as much as 1% of total virion proteins. Two-dimensional gel electrophoresis and immunoblotting with the antiserum against the heat shock protein 70 (hsp70) demonstrated that p73 was identical to a constitutive type of cellular hsp70. The antiserum also detected p73/hsp70 in the purified virions of other negative-stranded RNA viruses, such as vesicular stomatitis virus (New Jersey serotype), Newcastle disease virus (Miyadera strain), and influenza A virus (PR8 strain), among which, however, the contents were variable.

Cytolytic T lymphocyte precursors (CTL-P) were sensitized in vivo by intraplantar infection of C57BL/6 mice with a lethal dose of rabies virus, strain ERA (ERA). As a result of sensitization CTL-P matured to interleukin-receptive CTL-P (IL-CTL-P) that could be expanded in vitro to Thy-1+, Lyt-2+ CTL clones in the presence of IL without subjection to antigen-driven selection. After infection with ERA, IL-CTL-P-derived CTL lysed fibroblasts infected with rabies virus but not those infected with another rhabdovirus, the vesicular stomatitis virus. These CTL, however, did not discriminate between fibroblasts infected with the serologically closely related laboratory strains of classic rabies virus, ERA and HEP-Flury, and the serologically distinct rabies-related African isolate Mokola. This finding implies that in vivo sensitized IL-CTL-P recognize common genus-specific determinants expressed on cells infected with members of the lyssavirus genus.

Resistance to superinfection with vesicular stomatitis virus (VSV) occurred in GL-V3 monkey kidney cells infected with the CVS-11, Pitman Moore, LEP Flury, but not the ERA strain of rabies virus. Specific immunofluorescent staining of intracellular rabies antigen showed that the number and size of fluorescent foci increased after the onset of interference, and that this was paralleled by increasing yields of infectious virus. Although CVS-11 and ERA differed in their ability to induce interference, the virus yields from monolayers infected with either strain were similar. Interference apparently had no effect on the replication or dissemination of the inducing virus, and seems unrelated to the long incubation period or aberrant forms of infection in vivo.

A specific, saturable receptor for rabies virus was analyzed on cultured cells of neural or non-neural origin. Viral attachment kinetics were enhanced by DEAE-dextran, an effect which in turn enhanced the apparent infectivity of the virus inoculum. Under optimized conditions, the attachment of metabolically labeled ERA strain rabies virus obeyed the laws of mass action, whereby the amount of virus bound to cells varied proportionally with the concentration of cells or virus. Attachment was sensitive to changes of temperature and pH, did not require divalent cations such as Mg2+ or Ca2+, and occurred despite prior treatment of cells with proteolytic or sialic acid-specific enzymes. Saturation of the cell surface with rabies virus could be accomplished with 3 X 10(3) to 15 X 10(3) attached virions per cell. Competition for the rabies receptor occurred with rabies nonpathogenic variant virus, RV194 -2, and vesicular stomatitis virus. Reovirus type 3, another neurotropic virus, failed to inhibit rabies virus binding, and West Nile virus only slightly inhibited rabies virus binding, suggesting independent cellular receptors were recognized by these viruses. Isolated rabies virus glycoprotein failed to compete in an equivalent manner. However, solubilization of BHK-21 cells with octylglucoside yielded a chloroform-methanol-soluble extract which blocked rabies virus attachment. The binding inhibition activity of this extract was resistant to proteases but could be destroyed by phospholipases and neuraminidase, suggesting a phospholipid or glycolipid component at the receptor site. These data provide evidence for a rhabdovirus-common mechanism for cellular attachment to cells in culture.

We have developed a non-primate-based lentiviral vector based on the equine infectious anemia virus (EIAV) for efficient gene transfer to the central and peripheral nervous systems. Previously we have demonstrated that pseudotyping lentiviral vectors with the rabies virus glycoprotein confers retrograde axonal transport to these vectors. In the present study we have successfully produced high-titer EIAV vectors pseudotyped with envelope glycoproteins from Rhabdovirus vesicular stomatitis virus (VSV) serotypes (Indiana and Chandipura strains); rabies virus [various Evelyn-Rokitnicki-Abelseth ERA strains and challenge virus standard (CVS)]; Lyssavirus Mokola virus, a rabies-related virus; and Arenavirus lymphocytic choriomeningitis virus (LCMV). These vectors were delivered to the striatum or spinal cord of adult rats or muscle of neonatal mice by direct injection. We report that the lentiviral vectors pseudotyped with envelopes from the VSV Indiana strain, wild-type ERA, and CVS strains resulted in strong transduction in the striatum, while Mokola- and LCMV-pseudotyped vectors exhibited moderate and weak transduction, respectively. Furthermore ERA- and CVS-pseudotyped lentiviral vectors demonstrated retrograde transport and expression in distal neurons after injection in brain, spinal cord, and muscle. The differences in transduction efficiencies and retrograde transport conferred by these envelope glycoproteins present novel opportunities in designing therapeutic strategies for different neurological diseases.
