Mast cell recruitment is modulated by hairless skin microbiome.

Summary of "Mast cell recruitment is modulated by hairless skin microbiome."

Hairless mice have countless mast cells (MCs) in the skin and a more gram positive microbiome (GPM). MC number normalizes when TLR2, a GPM sensor, is deleted, proving a connection between hair-loss, GPM and MCs.

Innate Immunity Induces the Accumulation of Lung Mast Cells During Influenza Infection.

Mast cells release disease-causing mediators and accumulate in the lung of asthmatics. The most common cause of exacerbations of asthma is respiratory virus infections such as influenza. Recently, we ...

Regulation of the pleiotropic effects of tissue resident mast cells.

Mast cells, best known for their detrimental role in allergic diseases, act in a diverse array of physiological and pathological functions, made possible by the plurality of mast cell types. Their var...

Staphylococcus aureus in atopic dermatitis: Strain-specific cell wall proteins and skin immunity.

Atopic dermatitis (AD) is a common chronic skin disease. The presence of the bacterium Staphylococcus aureus (S. aureus) is frequently detected on skin affected with AD. In this review, we focused on...

Aged human skin accumulates mast cells with altered functionality which localise to macrophage and VIP nerve fibres.

Skin health declines with age and this is partially attributed to immunosenescence. Mast cells (MCs) are innate immune cells which coordinate tissue immune responses integral to skin homeostasis and d...

Engulfment of mast cell secretory granules upon skin inflammation boosts dendritic cell migration and priming efficiency.

Mast cells (MCs) are best known as key effector cells of allergic reactions but they also play an important role in host defense against pathogens. Despite increasing evidence for a critical impact of...

Mast Cell Activation Test in Allergic Disease

Activation of mast cells in the immune system is known to cause allergic reactions sometimes with severe systemic symptoms. The investigators have recently developed a blood-based mast cel...

Insights Into Microbiome and Environmental Contributions to Sickle Cell Disease and Leg Ulcers Study (INSIGHTS Study)

Background: - People with sickle cell disease and other blood disorders sometimes get chronic leg ulcers. These are wounds that develop on the skin and don t go away. Current treatments...

Study of Mast Cell Precursors

This study will investigate mast cell precursors that circulate in the blood. In a group of diseases collectively known as mastocytosis, mast cells accumulate in abnormal amounts in the sk...

The Gut and Skin Microbiome in Vitiligo Disease Progression

Investigators plan to perform a pilot study that aims to characterize the microbiome of human vitiligo patients with both active and stable disease and compare this to the microbiome of ag...

The Effect of Skin Cleansers on the Skin Surface Microbiome

This study determines the effects of a single application of different antiseptic skin cleansers on the composition of the skin surface microbiome using next-generation sequencing (NGS) te...

Medical and Biotech [MESH] Definitions

Granulated cells that are found in almost all tissues, most abundantly in the skin and the gastrointestinal tract. Like the BASOPHILS, mast cells contain large amounts of HISTAMINE and HEPARIN. Unlike basophils, mast cells normally remain in the tissues and do not circulate in the blood. Mast cells, derived from the bone marrow stem cells, are regulated by the STEM CELL FACTOR.

A unifocal malignant tumor that consists of atypical pathological MAST CELLS without systemic involvement. It causes local destructive growth in organs other than in skin or bone marrow.

A form of systemic mastocytosis (MASTOCYTOSIS, SYSTEMIC) characterized by the presence of large numbers of tissue MAST CELLS in the peripheral blood without skin lesions. It is a high-grade LEUKEMIA disease with bone marrow smear of >20% MAST CELLS, multi-organ failure and a short survival.

The secretion of histamine from mast cell and basophil granules by exocytosis. This can be initiated by a number of factors, all of which involve binding of IgE, cross-linked by antigen, to the mast cell or basophil's Fc receptors. Once released, histamine binds to a number of different target cell receptors and exerts a wide variety of effects.

A family of neutral serine proteases with TRYPSIN-like activity. Tryptases are primarily found in the SECRETORY GRANULES of MAST CELLS and are released during mast cell degranulation.
