Genetic control of experimental scrapie and Creutzfeldt-Jakob disease (CJD) was studied in inbred strains of mice by measuring the times from intracerebral inoculation with the agents to the onset of neurological dysfunction. Every strain of mice examined was susceptible to infection; however, a wide range of incubation times was found for both scrapie and(More)
Lymphocytes bearing the CD8 marker were shown to suppress replication of human immunodeficiency virus (HIV) in peripheral blood mononuclear cells. The effect was dose-dependent and most apparent with autologous lymphocytes; it did not appear to be mediated by a cytotoxic response. This suppression of HIV replication could be demonstrated by the addition of(More)
The incidence of human papillomavirus (HPV)-related cervical intraepithelial neoplasia (CIN) and cervical cancer is increased with immunodeficiency, but the role of immune response, including cell-mediated immunity, in disease prevention is not well understood. In this study, T-cell proliferative responses to six synthetic peptides with predicted(More)
Six isolates of the human immunodeficiency virus (HIV) showed differences in their ability to productively infect glioma-derived cell lines and early-passage human brain cell cultures. Susceptibility to HIV infection correlated well with the expression of the astrocyte marker glial fibrillary acidic protein. The CD4 molecule was expressed on some, but not(More)
Treatment of cells with tumor necrosis factor-alpha and interferon-gamma greatly reduces their susceptibility to infection with human immunodeficiency virus and suppresses the production of human immunodeficiency virus (HIV) mRNA, core protein p24, and infectious HIV. The combination treatment is cytotoxic for HIV-infected cells and reduces HIV RNA levels(More)
A reproducible method was developed to determine the ability of chlamydial antigens to stimulate lymphocytes from volunteers. In tests repeated 4 to 14 times, the cells from a given volunteer gave a relatively narrow range of responses, but there were great differences in the mean response of different volunteers. In the entire group of 52 volunteers,(More)
This study investigated whether acute and persistent stressors and life change events were followed by changes in immune status, and whether dispositional optimism moderated these relationships. Thirty-nine healthy women ages 18-45 were followed prospectively for 3 months, with weekly assessment of acute and persistent stressors and monthly assessment of(More)
We describe the methodology and architecture of a knowledge-based, interactive visualization system that enables physicians and medical support personnel to draw conclusions from heterogeneous time-oriented clinical data. Our system employs domain-specific ontologies to produce temporal and statistical abstractions of data, and also as the basis for(More)
