novel rabies virus-neutralizing epitope recognized by human monoclonal antibody: fine mapping and escape mutant analysis. | anti-rabies virus immunoglobulin combined with rabies vaccine protects humans from lethal rabies infections. for cost and safety reasons, replacement of the human or equine polyclonal immunoglobulin is advocated, and the use of rabies virus-specific monoclonal antibodies (mabs) is recommended. we produced two previously described potent rabies virus-neutralizing human mabs, cr57 and crjb, in human per.c6 cells. the two mabs competed for binding to rabies virus glycoprotein. using cr57 and a set ... | 2005 | 15795253 |
the application of reverse genetics technology in the study of rabies virus (rv) pathogenesis and for the development of novel rv vaccines. | rabies is a central nervous system (cns) disease that is almost invariably fatal. neurotropism, neuroinvasiveness, and transsynaptic spread are the main features that determine the pathogenesis of rabies. recent advances in rabies virus (rv) research, which made direct genetic manipulations of the rv genome possible, greatly improved the understanding of the role of different viral and host cell factors in the pathogenesis of rabies. here the authors discuss molecular mechanisms associated with ... | 2005 | 15804964 |
rabies virus receptors. | there is convincing in vitro evidence that the muscular form of the nicotinic acetylcholine receptor (nachr), the neuronal cell adhesion molecule (ncam), and the p75 neurotrophin receptor (p75ntr) bind rabies virus and/or facilitate rabies virus entry into cells. other components of the cell membrane, such as gangliosides, may also participate in the entry of rabies virus. however, little is known of the role of these molecules in vivo. this review proposes a speculative model that accounts for ... | 2005 | 15804965 |
the role of immune responses in the pathogenesis of rabies. | in the absence of treatment, infection with a variety of rabies virus strains most often results in a lethal outcome. this can be averted by prompt immunization following exposure demonstrating that the development of anti-rabies viral immunity prior to extensive infection of neurons is protective. otherwise it might be expected that immune clearance of the virus would result in neurological sequelae. thus, the capacity of a rabies virus to induce a protective immune response is a major, negativ ... | 2005 | 15804966 |
pathophysiology of human paralytic rabies. | furious rabies is a well-recognized clinical disorder in humans but the paralytic form is not as easily identified. the mechanisms responsible for the weakness and longer survival periods are not clear. several hypotheses have been proposed, including rabies virus variants associated with a particular vector, location of wounds, incubation period, influence of prior rabies vaccination, and virus localization in the central nervous system (cns). however, none of these have been substantiated. reg ... | 2005 | 15804967 |
neuronal dysfunction and death in rabies virus infection. | because morphologic changes in natural rabies are usually relatively mild, it is thought that the severe clinical disease with a fatal outcome must be due to neuronal dysfunction of rabies virus-infected neurons. the precise bases of this functional impairment are unknown, and current knowledge on electro-physiological alterations, effects on ion channels and neurotransmission, and neurotoxicity are reviewed. rabies virus may induce neuronal death, possibly through apoptotic mechanisms. neuronal ... | 2005 | 15804968 |
production of rabies neutralizing antibody in hen's eggs using a part of the g protein expressed in escherichia coli. | in an attempt to produce anti-rabies immunoglobulin affordable for people living in developing countries, we have immunized layer chickens with a part of the g protein of rabies virus expressed in escherichia coli. immunoglobulin (igy) was purified from the yolks of eggs layed by immunized hens. it was revealed in vitro that the antibody specifically bound to virions as well as cells infected with rabies virus. moreover, the antibody apparently neutralized rabies virus infectivity. inoculation o ... | 2005 | 15811649 |
persistence of elevated rabies prevention costs following post-epizootic declines in rates of rabies among raccoons (procyon lotor). | determining the benefits to cost relationships among different approaches to rabies control and prevention has been hindered by the inherent temporal variability in the dynamics of disease among wildlife reservoir hosts and a tangible and objective measure of the cost of rabies prevention. a major and unavoidable component of rabies prevention programs involves diagnostic testing of animals and the subsequent initiation of appropriate public health responses. the unit cost per negative and posit ... | 2005 | 15820116 |
