raccoonpoxvirus safety in immunocompromised and pregnant mouse models.numerous poxviruses infect humans and animal hosts, and a poxvirus vaccine with an improved safety profile is needed as the current vaccinia virus vaccine is contraindicated in individuals that have a history of eczema or heart disease, or are immunocompromised or pregnant. in addition, poxviruses make excellent vaccine vectors for other infectious diseases and cancer. raccoonpoxvirus is a naturally occurring attenuated north american poxvirus, and thus it is of interest as a vaccine vector plat ...201424837508
monosynaptic premotor circuit tracing reveals neural substrates for oro-motor coordination.feeding behaviors require intricately coordinated activation among the muscles of the jaw, tongue, and face, but the neural anatomical substrates underlying such coordination remain unclear. in this study, we investigate whether the premotor circuitry of jaw and tongue motoneurons contain elements for coordination. using a modified monosynaptic rabies virus-based transsynaptic tracing strategy, we systematically mapped premotor neurons for the jaw-closing masseter muscle and the tongue-protrudin ...201424843003
epidemiological characteristics of human and animal rabies in azerbaijan.the caucasus is a region of geopolitical importance, in the gateway between europe and asia. this geographical location makes the region equally important in the epidemiology and control of transboundary infectious diseases such as rabies. azerbaijan is the largest country in the caucasus, and although rabies is notifiable and considered endemic, there is little information on the burden of human and animal rabies. here, we describe a cross-disciplinary international collaboration aimed at impro ...201524845953
rabies in europe: what are the risks?rabies remains a serious endemic disease in animal populations in many european countries. oral vaccination by use of rabies vaccine baits has proved to be durably efficient for controlling and eliminating terrestrial rabies. however, the recurrence of rabies in some countries highlights the fragility of rabies-free country status and the need for continuous surveillance. in eastern and southern countries, the rabies control programmes for foxes should be accompanied by stray dog management meas ...201424847903
the analysis of vh and vl genes repertoires of fab library built from peripheral b cells of human rabies virus vaccinated donors.a human combinatorial fab antibody library was generated from immune repertoire based on peripheral b cells of ten rabies virus vaccinated donors. the analysis of random fab fragments from the unselected library presented some bias of v gene usage towards ighv-genes and iglv-gen families. the screening of the fab library on rabies virus allowed specific human fab antibody fragments characterized for their gene encoding sequences, binding and specificities to rv. genetic analysis of selected fabs ...201424862931
the adaptation of a ctn-1 rabies virus strain to high-titered growth in chick embryo cells for vaccine development.rabies virus is the causative agent of rabies, a central nervous system disease that is almost invariably fatal. currently vaccination is the most effective strategy for preventing rabies, and vaccines are most commonly produced from cultured cells. although the vaccine strains employed in china include ctn, ag, pm and pv, there are no reports of strains that are adapted to primary chick embryo cells for use in human rabies prevention in china.201424885666
how do we walk and chew gum at the same time?a genetic approach has been used to map the neural circuits that control and coordinate the tongue and jaw muscles.201424894467
genetically targeted binary labeling of retinal neurons.a major stumbling block to understanding neural circuits is the extreme anatomical and functional diversity of interneurons. subsets of interneurons can be targeted for manipulation using cre mouse lines, but cre expression is rarely confined to a single interneuron type. it is essential to have a strategy that further restricts labeling in cre driver lines. we now describe an approach that combines cre driver mice, recombinant adeno-associated virus, and rabies virus to produce sparse but binar ...201424899708

paralytic rabies following cat scratch and intra-dermal anti-rabies vaccination.only few reports of failure of intradermal postexposure prophylaxis for rabies following cat scratch exist in the published literature. we are reporting such a case in a 15-year-old girl. the child had category iii cat scratch on her face. she presented with progressive paralysis, finally developing quadriplegia and respiratory paralysis. typical hydrophobia and aerophobia were absent. she received intra-dermal anti-rabies cell culture vaccine. she did not receive anti-rabies immunoglobulin. the ...201425250074
rabies vaccination in a pediatric patient with acute myeloid leukemia during the course of chemotherapy: a case report.rabies is a fatal neurological infection caused by rabies virus. the deadly rabies virus could enter into human body via the wound that has caused by mammal bite. since rabies is a fatal disease without existing effective treatment, the best way is prevention. the widely examined preventive method for rabies is the use of post exposure rabies vaccination. in this specific case report, the author has presented an interesting case report of post exposure rabies vaccination in a pediatric patient w ...201425250158
comparison of biotinylated monoclonal and polyclonal antibodies in an evaluation of a direct rapid immunohistochemical test for the routine diagnosis of rabies in southern africa.the major etiological agent of rabies, rabies virus (rabv), accounts for tens of thousands of human deaths per annum. the majority of these deaths are associated with rabies cycles in dogs in resource-limited countries of africa and asia. although routine rabies diagnosis plays an integral role in disease surveillance and management, the application of the currently recommended direct fluorescent antibody (dfa) test in countries on the african and asian continents remains quite limited. a novel ...201425254652
clinical features and pathobiology of ebolavirus infection.there has clearly been a deluge of international press coverage of the recent outbreak of ebolavirus in africa and is partly related to the "fear factor" that comes across when one is confronted with the fact that once infected, not only is the speed of death in a majority of cases rapid but also the images of the cause of death such as bleeding from various orifices gruesome and frightening. the fact that it leads to infection and death of health care providers (10% during the current epidemic) ...201425260583
targeting dna vaccines to myeloid cells using a small peptide.targeting dna vaccines to dendritic cells (dcs) greatly enhances immunity. although several approaches have been used to target protein ags to dcs, currently there is no method that targets dna vaccines directly to dcs. here, we show that a small peptide derived from the rabies virus glycoprotein fused to protamine residues (rvg-p) can target dna to myeloid cells, including dcs, which results in enhanced humoral and t-cell responses. dcs targeted with a dna vaccine encoding the immunodominant va ...201425270431
anterograde glycoprotein-dependent transport of newly generated rabies virus in dorsal root ganglion neurons.rabies virus (rabv) spread is widely accepted to occur only by retrograde axonal transport. however, examples of anterograde rabv spread in peripheral neurons such as dorsal root ganglion (drg) neurons indicated a possible bidirectional transport by an uncharacterized mechanism. here, we analyzed the axonal transport of fluorescence-labeled rabv in drg neurons by live-cell microscopy. both entry-related retrograde transport of rabv after infection at axon endings and postreplicative transport of ...201425275124

the olfactory nerve: a shortcut for influenza and other viral diseases into the central nervous system.the olfactory nerve consists mainly of olfactory receptor neurons and directly connects the nasal cavity with the central nervous system (cns). each olfactory receptor neuron projects a dendrite into the nasal cavity on the apical side, and on the basal side extends its axon through the cribriform plate into the olfactory bulb of the brain. viruses that can use the olfactory nerve as a shortcut into the cns include influenza a virus, herpesviruses, poliovirus, paramyxoviruses, vesicular stomatit ...201525294743
establishment of myotis myotis cell lines--model for investigation of host-pathogen interaction in a natural host for emerging viruses.bats are found to be the natural reservoirs for many emerging viruses. in most cases, severe clinical signs caused by such virus infections are normally not seen in bats. this indicates differences in the virus-host interactions and underlines the necessity to develop natural host related models to study these phenomena. due to the strict protection of european bat species, immortalized cell lines are the only alternative to investigate the innate anti-virus immune mechanisms. here, we report ab ...201425295526
right place, wrong species: a 20-year review of rabies virus cross species transmission among terrestrial mammals in the united states.in the continental us, four terrestrial mammalian species are reservoirs for seven antigenic rabies virus variants. cross species transmission (cst) occurs when a rabies virus variant causes disease in non-reservoir species.201425295750
human rabies deaths in africa: breaking the cycle of indifference.the current outbreak of ebola virus disease has mobilized the international community against this deadly disease. however, rabies, another deadly disease, is greatly affecting the african continent, with an estimated 25 000 deaths every year. and yet, the disease can be prevented by a vaccine, if necessary with immunoglobulin, even when administered after exposure to the rabies virus. rabies victims die because of neglect and ignorance, because they are not aware of these life-saving biological ...201525303941
recombinant rabies virus expressing ifnα1 enhanced immune responses resulting in its attenuation and stronger immunogenicity.several studies have shown that type 1 interferons (ifns) exert multiple biological effects on both innate and adaptive immune responses. here, we investigated the pathogenicity and immunogenicity of recombinant rabies virus (rabv) expressing canine interferon α1 (rhep-caifnα1). it was shown that kun ming (km) mice that received a single intramuscular immunization with rhep-caifnα1 had an earlier increase and a higher level of virus-neutralizing antibody titers compared with immunization of the ...201425310498
developmental sculpting of intracortical circuits by mhc class i h2-db and h2-kb.synapse pruning is an activity-regulated process needed for proper circuit sculpting in the developing brain. major histocompatibility class i (mhci) molecules are regulated by activity, but little is known about their role in the development of connectivity in cortex. here we show that protein for 2 mhci molecules h2-kb and h2-db is associated with synapses in the visual cortex. pyramidal neurons in mice lacking h2-kb and h2-db (kbdb ko) have more extensive cortical connectivity than normal. mo ...201625316337
climate change and infectious diseases in the arctic: establishment of a circumpolar working group.the arctic, even more so than other parts of the world, has warmed substantially over the past few decades. temperature and humidity influence the rate of development, survival and reproduction of pathogens and thus the incidence and prevalence of many infectious diseases. higher temperatures may also allow infected host species to survive winters in larger numbers, increase the population size and expand their habitat range. the impact of these changes on human disease in the arctic has not bee ...201425317383
rhabdovirus-based vaccine platforms against henipaviruses.the emerging zoonotic pathogens hendra virus (hev) and nipah virus (niv) are in the genus henipavirus in the family paramyxoviridae. hev and niv infections can be highly fatal to humans and livestock. the goal of this study was to develop candidate vaccines against henipaviruses utilizing two well-established rhabdoviral vaccine vector platforms, recombinant rabies virus (rabv) and recombinant vesicular stomatitis virus (vsv), expressing either the codon-optimized or the wild-type (wt) hev glyco ...201525320306
expression of interferon gamma by a recombinant rabies virus strongly attenuates the pathogenicity of the virus via induction of type i interferon.previous animal model experiments have shown a correlation between interferon gamma (ifn-γ) expression and both survival from infection with attenuated rabies virus (rabv) and reduction of neurological sequelae. therefore, we hypothesized that rapid production of murine ifn-γ by the rabies virus itself would induce a more robust antiviral response than would occur naturally in mice. to test this hypothesis, we used reverse engineering to clone the mouse ifn-γ gene into a pathogenic rabies virus ...201525320312
apoptotic induction of lung adenocarcinoma a549 cells infected by recombinant rvg newcastle disease virus (rl-rvg) in vitro.newcastle disease virus (ndv) is a member of the genus avulavirus in the paramyxoviridae family and its antitumor properties depend on its ability to kill malignant cells while not affecting normal cells. the present study investigated a recombinant avirulent ndv lasota strain (wild-type ndv strain) expressing the rabies virus glycoprotein (rl-rvg), examined its oncolytic effect on the lung adenocarcinoma a549 cell line and evaluated its potential to serve as a vaccine against lung cancer. a549 ...201525322856
