IgE-mediated food allergy in which symptoms vary from mild skin reaction to anaphylactic shock is a pathological condition caused by IgE-mediated mast cell activation against ingested food antigens. Its prevalence has been increasing recent decades especially in developed countries and now nearly 5% of adults and 8% of children are affected by food allergy.

Although 4 mast cell mediators can be routinely measured, the results of initial testing to evaluate symptoms of mast cell activation have not been widely reported.
Colonic mast cells have been proposed to be related to the pathophysiology of irritable bowel syndrome (IBS). Whether mast cell counts are altered in the small intestine, a less-explored region in pat...
Previous studies have revealed an important role for the transcription factor GATA-1 in mast cell maturation and degranulation. However, there have been conflicting reports with respect to the require...
The expression of matrix metalloproteinases 2 and 9 have been described during the development, as an example in heart and tooth, but not in the small intestine yet. In this context, this study aimed ...
Mast cells are involved in the host immune response controlling infection with the non-invasive intestinal protozoan parasite Giardia intestinalis. Experimental infections in rodents with G. intestina...
The Mast Cell Connect Registry is a voluntary, observational database that will capture demographic, socioeconomic, and disease information directly from patients with mastocytosis via a s...
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...
To evaluate the efficacy of twice-daily oral doses of PKC412 when administered to patients with ASM/MCL and AHNMD (associated hematological clonal non-mast cell lineage disease) by measuri...
To assess the effects of olopatadine of the release of mast cell histamine
This study will examine growth factors that promote and inhibit mast cell proliferation resulting in mastocytosis, a disease of excessive mast cells in the body. These cells can release c...
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 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 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 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.
Food is any substance consumed to provide nutritional support for the body. It is usually of plant or animal origin, and contains essential nutrients, such as carbohydrates, fats, proteins, vitamins, or minerals. The substance is ingested by an organism ...
The term allergy is used to describe a response, within the body, to a substance, which is not necessarily harmful in itself, but results in an immune response and a reaction that causes symptoms and disease in a predisposed person, which in turn can cau...
