Mechanisms of human eosinophil survival and apoptosis

Abstract

Eosinophils, with their potentially harmful armoury of toxic products, have available a mechanism by which they can be cleared from the tissues while still intact in the absence of an undesirable pro-inflammatory response. However, our understanding of the induction and control of apoptosis in eosinophils is still incomplete and a great deal of work in this area remains to be done. In other cell types, important regulators of apoptosis have been well characterized. These include the proto-oncogene bcl-2 and related molecules, the family of proteases which share homology with IL-1 beta converting enzyme (ICE) and another protein family which interact with products of the proto-oncogene c-myc. These regulators act at various points on the apoptosis pathway and it appears their interactions are vital in determining whether a cell will survive or die. In particular, the ICE-like proteases have been implicated as a universal apoptosis effector which is associated with the downstream events of programmed cell death [62]. Whether these molecules are involved in the cell death pathway(s) of eosinophils remains to be determined. Much of eosinophilic inflammation might be a result of defects in pathways controlling eosinophil apoptosis a...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.
