| rabies virus infection of primary neuronal cultures and adult mice: failure to demonstrate evidence of excitotoxicity. | cultures derived from the cerebral cortices and hippocampi of 17-day-old mouse fetuses infected with the cvs strain of rabies virus showed loss of trypan blue exclusion, morphological apoptotic features, and activated caspase 3 expression, indicating apoptosis. the nmda (n-methyl-d-aspartate acid) antagonists ketamine (125 microm) and mk-801 (60 microm) were found to have no significant neuroprotective effect on cvs-infected neurons, while the caspase inhibitor ac-asp-glu-val aspartic acid aldeh ... | 2006 | 17005706 |
| regulation of ca2+/calmodulin kinase ii inhibitor alpha (camkiinalpha) in virus-infected mouse brain. | the alpha and beta isoforms of rat ca(2+)/calmodulin kinase ii inhibitor (camkiinalpha/beta) expressed in brain or brain and testis, respectively, are potent inhibitors of ca(2+)/calmodulin kinase ii (camkii) in vitro. however, the regulation or function of camkiinalpha/beta in the central nervous system (cns) is not known. in this study, we demonstrate that mouse camkiinalpha gene encodes a 2.9kb brain-specific transcript whose expression is downregulated in mouse brain during japanese encephal ... | 2006 | 17010311 |
| identification and characterization of a virus-inducible non-coding rna in mouse brain. | infection of mice with japanese encephalitis virus or rabies virus results in the activation of a gene encoding a novel, non-coding rna (ncrna) in the mouse central nervous system. this transcript, named virus-inducible ncrna (vinc), is identical to a 3.18 kb transcript expressed in mouse neonate skin (genbank accession no. ak028745) that, together with a number of unannotated cdnas and expressed sequence tags, is grouped in the mouse unigene cluster mm281895. vinc is expressed constitutively in ... | 2006 | 16760401 |
| molecular epidemiology of rabies from maranhão and surrounding states in the northeastern region of brazil. | although many outbreaks of rabies have been reported in northern brazil, few epidemiological studies of these outbreaks have been undertaken. in this study, molecular epidemiological analyses were performed using 41 rabies virus samples isolated in the maranhão (ma), pará (pa), and tocantins (to) states of northeastern brazil. a 599-bp region of the glycoprotein (g) gene was first amplified from each sample by rt-pcr, then sequenced and subjected to phylogenetic analysis. a phylogenetic tree div ... | 2006 | 16773238 |
| immunogenicity of cytopathic and noncytopathic viral vectors. | the impact of cytolytic versus noncytolytic viral infections on host responses is not well understood, due to limitations of the systems that have been used to address this issue. using paired cytopathic and noncytopathic rabies viruses that differ by only two amino acids, we investigated several fundamental aspects of the immune response to these viral vectors. greater cytopathic capacity translated into a greater degree of cross-priming to cd8(+) t cells (t(cd8)(+)) and more-robust short-term ... | 2006 | 16775313 |
| crystal structure of the rabies virus nucleoprotein-rna complex. | negative-strand rna viruses condense their genome into a helical nucleoprotein-rna complex, the nucleocapsid, which is packed into virions and serves as a template for the rna-dependent rna polymerase complex. the crystal structure of a recombinant rabies virus nucleoprotein-rna complex, organized in an undecameric ring, has been determined at 3.5 angstrom resolution. polymerization of the nucleoprotein is achieved by domain exchange between protomers, with flexible hinges allowing nucleocapsid ... | 2006 | 16778023 |
| two different conformations of rabies virus glycoprotein taken under neutral ph conditions. | we previously reported that the rabies virus glycoprotein (g) takes either of two different conformations (referred to as b and c forms) under neutral ph conditions, that could be differentiated by their reactivity to a monoclonal antibody (mab), #1-30-44, that recognizes the acid-sensitive conformational epitope, and the formation taken is dependent on two separate regions containing lys-202 and asn-336 of the protein (kankanamge et al., microbiol. immunol., 47, 507-519, 2003). semi-quantitativ ... | 2006 | 16785715 |
| rabies in apparently healthy dogs: histological and immunohistochemical studies. | a slaughterhouse survey for rabies virus infection among apparently healthy dogs slaughtered for human consumption was carried out in maiduguri, nigeria. formalin-fixed and paraffin-embedded tissues (salivary gland, hippocampus, cerebrum, medulla, and trigeminal ganglion) were obtained from a total of 52 head samples from slaughtered dogs. the paraffin-embedded tissues were analysed histologically using the haematoxylin and eosin (h&e) method for the presence of inclusion bodies and histochemica ... | 2006 | 16794650 |
| a chimpanzee-origin adenovirus vector expressing the rabies virus glycoprotein as an oral vaccine against inhalation infection with rabies virus. | rabies has the highest fatality rate of all human viral infections and the virus could potentially be disseminated through aerosols. currently licensed vaccines to rabies virus are highly effective but it is unknown if they would provide reliable protection to rabies virus transmitted through inhalation, which allows rapid access to the central nervous system upon entering olfactory nerve endings. here we describe preclinical data with a novel vaccine to rabies virus based on a recombinant repli ... | 2006 | 16797238 |
| the darc conspiracy--virus invasion tactics. | is there a "conspiracy" at work among viral pathogens? apparently, yes. rabies virus, lenti- and retroviruses, and herpesviruses, the "co-conspirators", target select members of the tumor necrosis factor (tnf) receptor superfamily to invade the cells of their host. the intrigue deepens, as several reports have revealed that the viral envelope proteins interact with the cellular tnf receptor in a highly conserved region of previously unknown function. targeting of this region by diverse pathogens ... | 2006 | 16807107 |
| a dna vaccine that encodes rabies virus glycoprotein lacking transmembrane domain enhances antibody response but not protection. | rabies virus (rv) glycoprotein (gp) consists of three domains: cytoplasmic, transmembrane and ectodomain. it occurs in a complete, membrane-bound form within the infected cell, but it is released from them in a deleted, secreted form lacking the transmembrane domain. this study was performed to test the importance of the transmembrane domain for the capability of the rv gp gene, introduced into mice via a recombinant plasmid (dna vaccine), to induce immune response and protection against challen ... | 2006 | 16808325 |
| rabies virus-induced apoptosis involves caspase-dependent and caspase-independent pathways. | previously, it has been shown that the laboratory attenuated rabies virus cvs-b2c, but not the wild-type virus shbrv, induces apoptosis in mice and the induction of apoptosis is mediated by viral glycoprotein. induction of apoptosis by cvs-b2c limits the spread of the virus in the cns. in the present study, we characterized the pathways by which cvs-b2c induces apoptosis. bsr cells were infected with cvs-b2c or shbrv and harvested at different time points for detection of apoptosis by immunofluo ... | 2006 | 16814422 |
| serological responses of adult dogs to revaccination against distemper, parvovirus and rabies. | serum antibody titres to canine distemper virus (cdv), canine parvovirus (cpv) and rabies were measured in dogs that had not been revaccinated annually and compared with the titres in a control group of regularly vaccinated animals; 83 per cent (171 of 207) of the dogs vaccinated against cdv one or more years earlier had serum neutralising antibody titres equal to or greater than 16; 64 per cent (136 of 213) of the dogs vaccinated against cpv one or more years earlier had haemagglutination inhib ... | 2006 | 16816154 |
| rabies virus glycoprotein as a carrier for anthrax protective antigen. | live viral vectors expressing foreign antigens have shown great promise as vaccines against viral diseases. however, safety concerns remain a major problem regarding the use of even highly attenuated viral vectors. using the rabies virus (rv) envelope protein as a carrier molecule, we show here that inactivated rv particles can be utilized to present bacillus anthracis protective antigen (pa) domain-4 in the viral membrane. in addition to the rv glycoprotein (g) transmembrane and cytoplasmic dom ... | 2006 | 16820183 |
| the histopathogenesis of paralytic rabies in six-week-old c57bl/6j mice following inoculation of the cvs-11 strain into the right triceps surae muscle. | a fatal encephalomyelitis was developed after intracerebral and hind limb inoculation of in 6-week-old c57bl/6j mice by the inoculation of fixed rabies virus (cvs-11 strain), intracerebrally and into hind. after the intracerebral inoculation, virus antigens were detected in the cerebral cortex and hippocampus at 2 days postinoculation (pi), and later spread centrifugally to thalamus, brain stem, cerebellum, spinal cord and spinal ganglia. at 4 days pi, severe apoptosis and dna fragmentation were ... | 2006 | 16820716 |
| molecular characterization of rabies virus isolates in china during 2004. | human rabies cases have been on the rise during the past few years in china and a total of 2651 cases were reported in 2004. to better understand the current rabies epidemics in china, we isolated rabies viruses from dogs and humans from five provinces and characterized these isolates genetically by sequencing the entire nucleoprotein (n) gene. comparison of the n genes among these isolates revealed 86.6-99.9% homology and these viruses can be grouped into three lineages. phylogenetic analysis i ... | 2006 | 16828520 |

| safety and efficacy of the oral rabies vaccine sag2 in raccoon dogs. | oral vaccination programmes in several rabies-infected countries from northern and eastern europe should not be restricted to foxes but should target raccoon dogs as well. the safety, immunogenicity and efficacy of rabigen sag2 bait was evaluated in raccoon dogs. safety of sag2 was demonstrated after direct instillation (n = 5) or ingestion of a bait (n = 5) using a quantity of virus at least 10 times superior to the field dose. all animals seroconverted and remained healthy. raccoon dogs were v ... | 2006 | 16603277 |
| the evolutionary history and dynamics of bat rabies virus. | rabies virus (rabv) is endemic in terrestrial mammals throughout the world and in bats on the american continent. we performed the most extensive phylogenetic analyses of bat rabv sequences undertaken to date using a variety of genes. our study supported previous suggestions that viral sequences are grouped according to the behaviour of the host species. however, there was more genetic and geographical diversity within each phylogenetic group than previously recognised, including evidence for ne ... | 2006 | 16621724 |
| the parvocellular lgn provides a robust disynaptic input to the visual motion area mt. | dorsal visual cortical areas are thought to be dominated by input from the magnocellular (m) visual pathway, with little or no parvocellular (p) contribution. these relationships are supported by a close correlation between the functional properties of these areas and the m pathway and by a lack of anatomical evidence for p input. here we use rabies virus as a retrograde transynaptic tracer to show that the dorsal area mt receives strong input, via a single relay, from both m and p cells of the ... | 2006 | 16630841 |
| molecular diversity of rabies viruses associated with bats in mexico and other countries of the americas. | bat rabies and its transmission to humans and other species in mexico were investigated. eighty-nine samples obtained from rabid livestock, cats, dogs, and humans in mexico were studied by antigenic typing and partial sequence analysis. samples were further compared with enzootic rabies associated with different species of bats in the americas. patterns of nucleotide variation allowed the definition of at least 20 monophyletic clusters associated with 9 or more different bat species. several lin ... | 2006 | 16672396 |
| airborne transmission of lyssaviruses. | in 2002, a scottish bat conservationist developed a rabies-like disease and subsequently died. this was caused by infection with european bat lyssavirus 2 (eblv-2), a virus closely related to rabies virus (rabv). the source of this infection and the means of transmission have not yet been confirmed. in this study, the hypothesis that lyssaviruses, particularly rabv and the bat variant eblv-2, might be transmitted via the airborne route was tested. mice were challenged via direct introduction of ... | 2006 | 16687600 |
