Chymase 1, mast cell

chymase, mast cell protease
This gene product is a chymotryptic serine proteinase that belongs to the peptidase family S1. It is expressed in mast cells and thought to function in the degradation of the extracellular matrix, the regulation of submucosal gland secretion, and the generation of vasoactive peptides. In the heart and blood vessels, this protein, rather than angiotensin converting enzyme, is largely responsible for converting angiotensin I to the vasoactive peptide angiotensin II. Angiotensin II has been implicated in blood pressure control and in the pathogenesis of hypertension, cardiac hypertrophy, and heart failure. Thus, this gene product is a target for cardiovascular disease therapies. This gene maps to 14q11.2 in a cluster of genes encoding other proteases. [provided by RefSeq, Jul 2008] (from NCBI)

Pathophysiologically relevant key features were quantified and correlated: transcripts of c-kit, FcεRIα, FcεRIβ, FcεRIγ, histidine decarboxylase, tryptase, and chymase; surface expression of c-Kit, FcεRIα; activity of tryptase, and chymase; histamine content and release triggered by FcεRI and Ca(2+) ionophore.
Mast cell chymase in experimentally induced psoriasis.
Harvima et al., Kuopio, Finland. In J Dermatol, Jan 2016
UNASSIGNED: Mast cell chymase can have a pro-inflammatory or an immunosuppressive function in psoriasis, but the outcome may depend on the level of chymase activity.
Sputum mast cell subtypes relate to eosinophilia and corticosteroid response in asthma.
Gibson et al., Newcastle, Australia. In Eur Respir J, Jan 2016
Sputum mast cell subtypes were determined by molecular phenotyping based on expression of mast cell biomarkers (tryptase (TPSAB1), chymase (CMA1) and carboxypeptidase A3 (CPA3)).
Increased asthma and adipose tissue inflammatory gene expression with obesity and Inuit migration to a western country.
Gibson et al., Copenhagen, Denmark. In Respir Med, Jan 2016
Adipose tissue biopsies were homogenised, RNA extracted, and PCR was performed to determine the relative gene expression of mast cell (tryptase, chymase, CPA3) and inflammatory markers (IL-6, IL-1β, and CD163).
Matrix Metalloproteinases as Regulators of Vein Structure and Function: Implications in Chronic Venous Disease.
Khalil et al., Boston, United States. In J Pharmacol Exp Ther, Dec 2015
Increased lower-extremity hydrostatic venous pressure is thought to induce hypoxia-inducible factors and other MMP inducers/activators such as extracellular matrix metalloproteinase inducer, prostanoids, chymase, and hormones, leading to increased MMP expression/activity, ECM degradation, VSM relaxation, and venous dilation.
Induction of Interleukin-9-Producing Mucosal Mast Cells Promotes Susceptibility to IgE-Mediated Experimental Food Allergy.
Wang et al., Cincinnati, United States. In Immunity, Nov 2015
Herein, we have reported the identification of multifunctional IL-9-producing mucosal mast cells (MMC9s) that can secrete prodigious amounts of IL-9 and IL-13 in response to IL-33, and mast cell protease-1 (MCPt-1) in response to antigen and IgE complex crosslinking, respectively.
The mast cell as a pluripotent HDL-modifying effector in atherogenesis: from in vitro to in vivo significance.
Kovanen et al., Helsinki, Finland. In Curr Opin Lipidol, Oct 2015
Upon activation, mast cells degranulate and expel 2 major neutral proteases, chymase and tryptase, and the vasoactive compound histamine, all of which are bound to the heparin-proteoglycan matrix of the granules.
