Abstract

The T cell responses of Moloney leukemia virus (MoLV)-infected preleukemic BALB/c mice were examined. The major in vitro response detectable was T cell blastogenesis in response to the major viral envelope protein MoLV gp71 and an internal viral protein p12. The majority of the preleukemic mice had readily detectable responses to gp71, whereas the presence of a response to p12 was less consistent. With both antigens, T cell blastogenesis showed typical antigen response characteristics similar to those detected in other immune responses to C-type viruses. Proliferation was dependent on a Thy-1+, Lyt-1+, 2- population and was macrophage-independent. In contrast to most immune responses to C-type viruses, which are temporally restricted, T cell blastogenesis was detectable throughout the preleukemic period of 4 to 16 wk of age. During this period neither gp71-specific T cells nor PHA-responsive T cells were found to express viral antigens. The correlations between T cells responding to gp71 and leukemia were examined. Under conditions in which MoLV inoculation of BALB/c mice does not induce leukemia, no T cell responses were deectable. These results suggest a causal relationship between the presence of antigen-specific T cells and...Continue Reading

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.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

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.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. 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.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
