Development of tumours in mice chronically infected with herpes simplex virus

Abstract

Tumours developed in chronic infection lasting for 150--180 days in 39 (60%) of 65 mice infected with strain L2 of herpes simplex virus (HSV) type 1 and in 12 (20%) of 60 mice infected with strain 333 of HSV type 2. Similar results were obtained in 150 immunosuppressed mice chronically infected with HSV types 1 and 2. Pathomorphologically, the neoplasias in the first group (strain L2) were similar to adenocarcinoma and malignant lymphoma and in the second (strain 333) to lymphoma and angio- or fibrosarcoma. The respective HSV strains were isolated by cocultivation of blood leukocytes from chronically infected animals and cultures of the tumour cells with human embryo fibroblasts (HEF). HSV and Gross murine leukaemia virus antigens were detected in tumour cells by immunofluorescence and radioimmunoassay, respectively, and HSV antigen by immunofluorescence also in cultures of tumour cells and in cells of the brains, spinal cords, livers and spleens of the animals. HSV antibody was demonstrable in the blood serum from chronically infected tumour-bearing mice in a titre of 32.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Synapse Loss as Therapeutic Target in MS

As we age, the number of synapses present in the human brain starts to decline, but in neurodegenerative diseases this occurs at an accelerated rate. In MS, it has been shown that there is a reduction in synaptic density, which presents a potential target for treatment. Here is the latest research on synapse loss as a therapeutic target in MS.

Artificial Intelligence in Cardiac Imaging

Artificial intelligence (ai) techniques are increasingly applied to cardiovascular (cv) medicine in cardiac imaging analysis. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

Social learning involves learning new behaviors through observation, imitation and modeling. Follow this feed to stay up to date on the latest research.

Cell Atlas of the Human Eye

Constructing a cell atlas of the human eye will require transcriptomic and histologic analysis over the lifespan. This understanding will aid in the study of development and disease. Find the latest research pertaining to the Cell Atlas of the Human Eye here.

Single Cell Chromatin Profiling

Techniques like ATAC-seq and CUT&Tag have the potential to allow single cell profiling of chromatin accessibility, histones, and TFs. This will provide novel insight into cellular heterogeneity and cell states. Discover the latest research on single cell chromatin profiling here.
