Positive selection of a T-cell subpopulation in the thymus in which it develops

Abstract

In SWR mice the expression with high-density V beta 17a (high V beta 17a) of the T-cell antigen receptors correlates with the CD4+8- subpopulation of thymocytes. By contrast, in thymocytes of SJL mice the expression of high V beta 17a is observed on the CD4+8- or CD4-8+ subpopulation. However, when the thymocytes from SWR mice have been developed in the SJL or B10 thymus but not in the H-2 compatible DBA/1 thymus, a greater proportion of thymocytes that express high V beta 17a was found to be CD4-8+. By contrast, only a small proportion of KJ23a+ thymocytes from SJL mice that had differentiated in the thymus of SWR or DBA/1 mice was CD4-8+, whereas a high proportion of CD4+8- cells expressed V beta 17a. Further, an intermediate proportion of KJ23a+ thymocytes that had derived from SJL donor mice was present on CD4-8+ thymocytes that had developed in B10.A(4R) thymus. These findings demonstrate that the appearance of a particular subpopulation of thymocytes (CD4-8+ with a beta chain of T-cell antigen receptor identified as V beta 17a) is determined by the histocompatibility complex products that are expressed in the thymic microenvironment in which the T cells develop.

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.
