We examined the axonal transport of two strains of herpes simplex virus 1 (HSV-1) within the central nervous system of cebus monkeys. Each strain was injected into the "arm area" of the primary motor cortex. One strain, HSV-1(McIntyre-B), was transported transneuronally in the retrograde direction. It infected neurons at sites known to project to the arm(More)
PURPOSE Fluorescein and rose bengal are dyes used routinely in the examination of the ocular surface. As part of an ongoing search for a superior ophthalmic dye with optimal specificity and sensitivity and a lack of interference with subsequent viral cultures, and as part of studies that use chemical dyes to understand better the pathophysiology of ocular(More)
PURPOSE To evaluate and compare the in vivo administration of interleukin-2 (IL-2) or interleukin-12 (IL-12) in the immunotherapy of necrotizing retinitis caused by murine cytomegalovirus (MCMV) in mice with a retrovirus-induced immunodeficiency syndrome (MAIDS). METHODS Adult C57BL/6 mice with MAIDS of 8 weeks' duration were treated with either a single(More)
Progressive ascending myelitis was the presenting feature of the acquired immune deficiency syndrome (AIDS) in a homosexual man who also had Kaposi's sarcoma, Pneumocystis pneumonia, and disseminated cytomegalovirus (CMV) infection. Neuropathological studies showed profuse cytomegalic cells throughout the brain and spinal cord, but no inflammatory response.(More)
Within a 5-month period, 2 homosexual men with persistent lymphadenopathy developed clinical findings consistent with herpes simplex virus (HSV) encephalitis. These signs included abrupt change in mental status, seizures, cerebrospinal fluid pleocytosis, and localized electroencephalographic abnormalities showing temporal lobe involvement. Initial computed(More)
Human neural cell aggregate cultures were prepared from dissociated fetal brain tissue and maintained in rotation culture. After 35 days in culture, aggregates had the histologic appearance of dense, immature, neural cells in a tightly packed neuropil. Electron microscopy revealed ultrastructural features suggestive of immature neurons and neuroglia. In(More)
The physiological condition of the retinas of BALB/c mice inoculated unilaterally in the anterior chamber with the KOS strain of herpes simplex virus type 1 (HSV-1) was monitored by ERG recordings. After the ERG recordings, the retinas were examined for histopathological changes. In the inoculated eye, depressed ERGs were recorded on day 2 PI and abolished(More)
Over a one-year period the cerebrospinal fluid (CSF) obtained from a series of homosexual men immunocompromised with either Hodgkin's disease or acquired immune deficiency syndrome (AIDS) was cultured to assess the frequency with which infectious viruses could be recovered. Of 58 patients examined, 4 (6.9%) had CSF cultures that showed a cytopathology(More)
The neovascular (wet) form of age-related macular degeneration (AMD) leads to vision loss due to choroidal neovascularization (CNV). Since macrophages are important in CNV development, and cytomegalovirus (CMV)-specific IgG serum titers in patients with wet AMD are elevated, we hypothesized that chronic CMV infection contributes to wet AMD, possibly by(More)
A 54-year-old man developed clinical findings consistent with herpes simplex virus (HSV) encephalitis. These signs included an abrupt onset of focal central nervous system disease, cerebrospinal fluid pleocytosis, localized electroencephalographic abnormalities, and a computerized tomographic scan showing right temporal lobe involvement. Treatment with(More)
