14. Multiplex PCR for diagnosis of AIDS-related central nervous system lymphoma and toxoplasmosis.
A nested multiplex PCR assay was designed for the simultaneous detection of Epstein-Barr virus and Toxoplasma gondii DNA from the cerebrospinal fluid of AIDS patients. T. gondii DNA was detected in 8 of 8 patients with Toxoplasma encephalitis and in 0 of 6 patients without toxoplasmosis, and Epstein-Barr virus DNA was found in 9 of 14 patients with central n

16. Epstein-Barr virus-specific cytotoxic T cell responses in HIV-1 infection: different kinetics in patients progressing to opportunistic infection or non-Hodgkin's lymphoma.
Although the high incidence of EBV-associated diffuse large cell lymphomas (DLCL) in HIV-1 infection is believed to be related to loss of immune control due to HIV-induced immune deficiency, it has been claimed that cytotoxic T lymphocyte (CTL) responses to EBV are longer lasting in HIV-1-infected persons than CTL directed against HIV-1 itself. We approached

17. Human Immunodeficiency Virus (HIV) Type 1 Vpu Induces the Expression of CD40 in Endothelial Cells and Regulates HIV-Induced Adhesion of B-Lymphoma Cells
AIDS-related B-cell non-Hodgkin's lymphoma (AIDS-NHL) is a significant cause of morbidity and mortality among individuals infected with human immunodeficiency virus type 1 (HIV-1). AIDS-NHL is clinically and histologically heterogeneous, but common features include an aggressive clinical course and frequent extranodal presentation. HIV-1 infection of nonimmu

18. In situ polymerase chain reaction-based localization studies support role of human herpesvirus-8 as the cause of two AIDS-related neoplasms: Kaposi's sarcoma and body cavity lymphoma.
Several lines of investigation point to a new herpesvirus, human herpesvirus-8 (HHV-8), as the cause of two different neoplasms seen in AIDS patients-Kaposi's sarcoma (KS) and body cavity B cell lymphoma. If this virus is the etiological agent, rather than another opportunistic infectious agent, it should be present in the earliest detectable clinical lesion

19. Alterations of the p53 gene in Epstein-Barr virus-associated immunodeficiency-related lymphomas.
Mutations of the p53 tumor suppressor gene are among the most common genetic alterations found in many different human malignancies, including those of the colon, lung, and breast. Alterations in wild-type p53 lead to loss of the suppressor function and thus contribute to tumorigenesis. The potential role of p53 mutations in a sampling of B-cell lymphomas, t

20. Presence of Epstein-Barr virus latency type III at the single cell level in post-transplantation lymphoproliferative disorders and AIDS related lymphomas.
AIMS: To investigate the expression pattern of Epstein-Barr virus (EBV) latent genes at the single cell level in post-transplantation lymphoproliferative disorders and acquired immunodefiency syndrome (AIDS) related lymphomas, in relation to cellular morphology. METHODS: Nine post-transplantation lymphoproliferative disorders and three AIDS related lymphomas

21. Expression of the Epstein–Barr virus latent membrane protein 1 induces B cell lymphoma in transgenic mice
The latent membrane protein 1 (LMP1) of the Epstein–Barr virus has transforming properties in rodent fibroblasts and is expressed in most of the cancers associated with Epstein–Barr virus (EBV) infection including posttransplant lymphomas, Hodgkin’s disease, nasopharyngeal carcinoma, and AIDS-related lymphomas. In this study, three lineages of LMP1 tra

22. Classic AIDS in a Sooty Mangabey after an 18-Year Natural Infection
Prevailing theory holds that simian immunodeficiency virus (SIV) infections are nonpathogenic in their natural simian hosts and that lifelong infections persist without disease. Numerous studies have reported that SIV-infected sooty mangabeys (SMs; Cercocebus atys) remain disease free for up to 24 years despite relatively high levels of viral replication. He

23. Primary characterization of a herpesvirus agent associated with Kaposi's sarcomae.
Detection of novel DNA sequences in Kaposi's sarcoma (KS) and AIDS-related body cavity-based, non-Hodgkin's lymphomas suggests that these neoplasms are caused by a previously unidentified human herpesvirus. We have characterized this agent using a continuously infected B-lymphocyte cell line derived from an AIDS-related lymphoma and a genomic library made fr

24. Isolation of a type D retrovirus from B-cell lymphomas of a patient with AIDS.
An atypical syncytial variant of a high-grade Burkitt's-type B-cell lymphoma from a patient with AIDS who was seropositive for human immunodeficiency virus type 1 was studied. A productive type D retrovirus infection was identified in early-passage cell lines derived from two lymphomas from this patient. Nucleotide and amino acid sequence analysis as well as
