Cation exchanger properties of isolated rat peritoneal mast cell granules. 1985

B Uvnäs, and C H Aborg, and L Lyssarides, and J Thyberg

The synthetic carboxylic cation exchanger resin Amberlite IRC-50 was charged with histamine by suspension in histamine-containing solution with admixture of [14C]histamine. Mast cell granules were isolated from mast cells suspended in isotonic sucrose. The release of histamine induced from the two materials by superfusion with isotonic NaCl and KCL solutions showed identical kinetics, in accordance with the view that the release of histamine is due to a cation exchange: Na+ (K+) in equilibrium Hi+ at carboxyl groups in the granule heparin-protein complex.

UI MeSH Term Description Entries
D007475 Ion Exchange Resins High molecular weight, insoluble polymers which contain functional groups that are capable of undergoing exchange reactions (ION EXCHANGE) with either cations or anions. Ion Exchange Resin,Exchange Resin, Ion,Exchange Resins, Ion,Resin, Ion Exchange,Resins, Ion Exchange
D008407 Mast Cells 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. Basophils, Tissue,Basophil, Tissue,Cell, Mast,Cells, Mast,Mast Cell,Tissue Basophil,Tissue Basophils
D010477 Perfusion Treatment process involving the injection of fluid into an organ or tissue. Perfusions
D011189 Potassium Chloride A white crystal or crystalline powder used in BUFFERS; FERTILIZERS; and EXPLOSIVES. It can be used to replenish ELECTROLYTES and restore WATER-ELECTROLYTE BALANCE in treating HYPOKALEMIA. Slow-K,Chloride, Potassium
D011919 Rats, Inbred Strains Genetically identical individuals developed from brother and sister matings which have been carried out for twenty or more generations or by parent x offspring matings carried out with certain restrictions. This also includes animals with a long history of closed colony breeding.

D003594 Cytoplasmic Granules Condensed areas of cellular material that may be bounded by a membrane. Cytoplasmic Granule,Granule, Cytoplasmic,Granules, Cytoplasmic
D006636 Histamine Release 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. Histamine Liberation,Histamine Liberations,Histamine Releases
D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA. Animal,Metazoa,Animalia
D000837 Anion Exchange Resins High-molecular-weight insoluble polymers that contain functional cationic groups capable of undergoing exchange reactions with anions. Anion Exchange Resin,Anion Exchangers (Resins),Exchange Resin, Anion,Exchange Resins, Anion,Resin, Anion Exchange,Resins, Anion Exchange
