Plastic and Reconstructive Surgery, 2004
Hemangioma is a primary tumor of the microvasculature in which angiogenesis is initially excessive, followed by spontaneous regression of the newly formed vessels, with the cellular parenchyma gradually being replaced with fibrofatty tissue. Mast cells, which are highly heterogenous in terms of their morphology, function, and metabolic products, have ...

On the Heterogeneity of Mast Cells
Pharmacology, 2008Mast cells from different locations are shown to vary in their histochemical, ultrastructural, cytochemical and functional properties. The clinical consequences of this heterogeneity and possible reasons for its origin are discussed.

For half a century, it has been known that the mast cell is the cell responsible for the majority of anaphylactic events. Its mediators, taken as a whole, are capable of producing all of the clinical manifestations of these events. With the discovery of immunoglobulin E (IgE), it was originally felt that the vast majority of anaphylactic episodes were ...

Autopsy of a patient with well-documented myelofibrosis revealed marked proliferation of mast cells associated with areas of bone-marrow and splenic fibrosis. The findings suggest that the local fibrosis represents the healed phase of an inflammatory reaction mediated by mast cells via the release of histamine into the tissue spaces.

Mast Cell–Targeting Therapies in Mast Cell Activation Syndromes
Current Allergy and Asthma ReportsProvide an overview of the expanding landscape of mast cell (MC)-targeting treatments in mast cell activation syndromes (MCAS).Tyrosine-kinase inhibitors (TKIs) targeting wild-type and mutated KIT can efficiently induce MC depletion. Avapritinib and midostaurin can also temper IgE-mediated degranulation.

Science, 1966
Subcutaneous injections of normally well tolerated amounts of hypertonic NaCl or urea solutions produce extensive topical necroses in rats systemically treated with various mast-cell dischargers and mast-cell products. This response is considered to be closely related to mast-cell function, for it cannot be duplicated by systemic treatment with a ...

Mast cells (MCs) typically reside at barrier sites of the body, including the intestinal mucosa, and play a vital role in innate host defence. Activated MCs release a wide variety of bioactive mediators. These include preformed mediators stored in the granules (e.g. histamine and tryptase) and newly synthesised mediators (e.g.

Mast cells secrete histamine, glycosaminoglycans, arachidonic acid derivatives, enzymes, and possibly whole granules. Physiologic stimuli include the bridging of membrane-bound IgE molecules by antigen, the anaphylatoxins C5a and C3a, and the neurotransmitter acetylcholine.

Apoptosis is a physiological form of cell death. Cells undergoing apoptosis execute a genetically controlled program that leads to organized breakdown of cellular structures and ends in phagocytosis of their remains. In mast cells, several mechanisms regulating apoptosis have been identified including growth factors, tumor necrosis factor-alpha ...
