Vesicular Trafficking and Signaling for Cytokine and Chemokine Secretion in Mast Cells

Abstract: Upon activation mast cells (MCs) secrete numerous inflammatory compounds stored in their cytoplasmic secretory granules by a process called anaphylactic degranulation, which is responsible for type I hypersensitivity responses. Prestored mediators include histamine and MC proteases but also some cytokines and growth factors making them available within minutes for a maximal biological effect. Degranulation is followed by the de novo synthesis of lipid mediators such as prostaglandins and leukotrienes as well a… Show more

“…С точки зрения стадийности биогенеза выделяют три типа секреторных гранул [57]. Тип I представляет собой созревающие эндо-сомы или лизосомы с многочисленными лю-минальными везикулами внутри, формирую-щиеся с участием протеинов Rab5 и ВАМБ-8 (рис.…”

“…The antigen-mediated cross-linking of the highaffinity immunoglobulin E (IgE) receptor FcεRI triggers Ca 2+ -dependent exocytosis of secretory granules (SGs) referred to as degranulation, and results in the release of preformed mediators with a diversity of biological activities (26). Similar to other Ca 2+ -dependent regulated exocytosis such as neurotransmitter release, mast cell degranulation involves the fusion of SGs with the plasma membrane (PM), which is driven by a subset of the soluble N-ethylmaleimide-sensitive fusion protein attachment protein receptor (SNARE) family of proteins, and is regulated by various proteins belonging to the Munc13, Munc18, synaptotagmin, complexin, or Doc2 families or to the Rab family of small GTPases (6,26). Ca 2+ -dependent regulated exocytosis is generally subdivided into three processes, vesicle docking, priming, and fusion, in chronological order (19,31).…”
