Malignant plasma cell tumors in human immunodeficiency virus-infected patients

Cancer, 1990
The development of malignant neoplasms in patients with the acquired immune deficiency syndrome (AIDS) or with a positive human immunodeficiency virus (HIV) antibody test is a well known phenomenon. According to the guidelines from the Centers for Disease Control (Atlanta, GA), the presence of intermediate-grade or high-grade B-cell non-Hodgkin's ...

Superantigens and retroviral infection: insights from mouse mammary tumor virus

Immunology Today, 1994
Superantigens induce a vigorous immune response by stimulating T cells that express particular T-cell receptor V beta chains. Mouse mammary tumor virus is a milk-transmitted retrovirus that encodes such a superantigen. Paradoxically, as discussed by Werner Held and colleagues, the strong superantigen-induced immune response permits the survival of the ...

Transgenic mouse mammary tumor virus superantigen expression prevents viral infection

Cell, 1992
Endogenous mouse mammary tumor virus (MMTV) proviruses have recently been shown to cosegregate genetically with the minor lymphocyte-stimulating loci, also termed self-superantigens. The antigenic activity has been localized to the open reading frame (ORF) protein encoded in the long terminal repeat of MMTV. We show here that unlike their nontransgenic

Influenza Virus Infection of Transplanted Tumors

The Journal of Immunology, 1955
Summary Transplantation of Sarcoma 37, infected in vitro with neurotropic-WS influenza virus (NWS), to virus-immune mice resulted in rapid disappearance of infective virus from the grafts and unimpaired tumor growth. NWS virus, present as a “passenger” in attenuated sarcomas, was also rapidly neutralized after transplantation of the ...

Murine mammary tumor virus: characterization of infection of nonmurine cells

Journal of Virology, 1976
Murine mammary tumor virus (MuMTV) was used to productively infect feline and mink cells. MuMTV "proviral" DNA could be detected in the infected cells by molecular hybridization using radioactive MuMTV complementary DNA as a probe. Kinetic analysis of MuMTV proviral DNA synthesis after infection showed that maximum MuMTV DNA synthesis was achieved by 8

Ultrastructure of Tumor Cells in Marek's Disease Virus-Infected Chickens

American Journal of Veterinary Research, 1973
SUMMARY Marek's disease (md) visceral tumors from 5½-week-old chickens exposed to the GA isolate of md herpsvirus (mdhv) were examined by electron microscopy determine the fine structure of the lesion. In contrast to the neural lesions of md, which are composed of a mixture of cell types, the visceral tumors contained only one cell type, an immature ...

Abrogation of infectivity of mouse mammary tumor virus by reserpine

Experimental pathology, 1982
Summary Treatment of mouse mammary tumor virus (MMTV) with reserpine in vitro or administration of reserpine 30 min after MMTV inoculation abolishes the viral infectivity in mice.

Superantigen-induced immune stimulation amplifies mouse mammary tumor virus infection and allows virus transmission

Cell, 1993
Endogenous and infectious mouse mammary tumor viruses (MMTVs) encode in their 3' long terminal repeat a protein that exerts superantigen activity; that is, it is able to interact with T cells via the variable domain of the T cell receptor (TCR) beta chain.

Mouse mammary tumor virus infections: viral expression and tumor risk.

Journal of the National Cancer Institute, 1979
Concentrations of murine mammary tumor virus (MuMTV) antigen in the milk of individual naturally infected BALB/cfC3H and BALB/c mice given injections of MuMTV were related to their risk of developing a mammary tumor. Two distinct groups of MuMTV-infected mice were identified.

BK Virus, JC Virus and Simian Virus 40 Infection in Humans, and Association with Human Tumors

2007
BK virus (BKV), JC virus (JCV) and Simian Virus 40 (SV40) are polyomaviruses, highly homologous at the DNA and protein levels. While the human polyomaviruses BKV and JCV are ubiquitous in humans, SV40 is a simian virus which was introduced in the human population, between 1955 and 1963, by contaminated poliovaccines produced in SV40-infected monkey ...
