Current concepts and treatment advances in systemic mastocytosis

Abstract

Mast cell disorders are defined by an abnormal accumulation of tissue mast cells in one or more organ systems. Clinical symptoms in mastocytosis result from mast cells derived mediators and, less frequently, from destructive infiltration of mast cells. Systemic mastocytosis is regressive among children, whereas the disease is persistent among adults. A clonal haematological non-mast cell lineage disease can be associated. The clinical course in these patients is variable ranging from asymptomatic for years to highly aggressive and rapidly devastating. Until recently, the only treatment of this incurable disease was symptomatic. Recent advances were done in understanding the physiopathology of this myeloproliferative syndrome which results from an activating mutation of the stem cell factor receptor: C-Kit. A somatic C-Kit mutation is usually detectable in mast cells and their progenitors. Different mutations were found and the mutation D816V is the most frequent. Their specific transduction paths were also studied. Diagnosis of systemic mastocytosis does not only rest upon pathological examination but also on molecular as well as immunological and immunochemical tools. Physiopathological advancements led to suggest new treatmen...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.
