Neuronal loss in a lower motor neuron disease induced by a murine retrovirus
1Laboratory of Molecular Biology, Clinical Research Institute of Montreal, Quebec, Canada.
Abstract:
An animal model of neuronal loss induced by a murine retrovirus is described. The neurological disease is manifested by a lower limb paralysis and is characterized as a spongiform myeloencephalopathy. The primary determinant of neurovirulence has been mapped within the viral env sequences and a secondary determinant is present within the LTR region. A model of pathogenesis, suggesting that the disease is receptor-mediated, is proposed.
