- AB It is now well documented that human immunodeficiency virus type 1
- (HIV-1) induces encephalopathy in patients with AIDS. In vitro studies
- have implicated the envelope protein (gp120) as a factor which causes
- neuronal death. To better evaluate the role and elucidate the mechanisms
- of gp120 neurotoxicity, we have developed transgenic mice carrying a
- segment of the HIV-1 genome that expresses the viral gp160 protein under
- the control of the human neurofilament light gene promoter. In two
- separate lines of transgenic mice, the Env protein was found to be
- expressed in several nuclei of the brain stem and in the anterior horns
- of the spinal cord. The two lines showed identical patterns of Env
- expression. Neuropathological evaluation revealed numerous abnormal
- dendritic swellings in the immunostained motor neuron structures. Large
- and numerous neuritic swellings were also prominent in the nucleus
- gracilis and in the gracilis and cuneate fascicles. In addition,
- reactive astrocytosis was observed in several immunoreactive areas of
- the central nervous system. These transgenic mice offer a unique model
- to further investigate the role of HIV-1 Env protein in neuronal
- toxicity and to help elucidate the mechanisms that are involved.
