Tryptase mast cell
WebActivated mast cells are involved in the pathogenesis of MCADs, but also in other disorders making appropriate diagnosis and treatment challenging. The definition of mast cell activation should be expanded beyond histamine and tryptase, with an emphasis on better detection and treatments. WebHuman mast cells are broadly grouped into three categories based on the types of proteases released upon degranulation: tryptase-positive mast cells (MCT) which secrete tryptases, chymase-positive mast cells (MCC) which secrete chymases, and tryptase-chymase-positive mast cells (MCTC) which secrete both.
