Dysfunctional neural control of airway smooth muscle (ASM) is involved in inflammatory diseases, such as asthma. However, neurogenesis in the lung is poorly understood. This study uses mouse models to investigate developmental mechanisms of ASM innervation, a process that is highly coordinated with ASM formation during lung branching morphogenesis. We show that brain-derived neurotrophic factor...
Asthma is characterized by the association of airway hyperresponsiveness (AHR), inflammation, and remodelling. The aim of the present article is to review the pivotal role of airway smooth muscle (ASM) in the pathophysiology of asthma. ASM is the main effector of AHR. The mechanisms of AHR in asthma may involve a larger release of contractile mediators and/or a lower release of relaxant mediato...
Activation of Toll-like receptors (TLRs) on immune surveillance cells in the lung has been implicated in the pathobiology of allergic asthma, a condition associated with altered airway smooth muscle (ASM) contractility. Because ASM is known to directly respond to various proasthmatic stimuli, the potential role of TLR signaling in ASM in regulating airway expression of the proasthmatic phenotyp...
Gurevich’s Abstract State Machines (ASMs) are computational models of systems specified in a high level language (ASM-SL). In this paper, we investigate the pros and cons of the automatic verification of ASM models using the ASM-Workbench and its extention ASM-SMV, which supports computer-aided verification by model checking. The results obtained are based on the validation and verification of ...
BACKGROUND Mast cell localization within the airway smooth muscle (ASM)-bundle plays an important role in the development of airway hyper-responsiveness (AHR). Genomewide association studies implicate the 'alarmin' IL-33 in asthma, but its role in mast cell-ASM interactions is unknown. OBJECTIVES We examined the expression and functional role of IL-33 in bronchial biopsies of patients with an...
TO THE EDITOR: We just witnessed an interesting debate, with lowdown punches, on the potential role of airway smooth muscle (ASM) in asthmatic airway hyperresponsiveness (AHR) when the ASM proponents Drs. Gunst and Panettieri faced the ASM opponents Drs. Paré and Mitzner (2). However, part of the disagreement seems to lie upon the vocabulary used. On one hand, the proponents reported that sever...
Increased airway smooth muscle (ASM) mass and infiltration by mast cells are key features of airway remodeling in asthma. We describe a model to investigate the relationship between ASM, the extracellular matrix, mast cells, and airway remodeling. ASM cells were cultured in a three-dimensional (3-D) collagen I gel (3-D culture) alone or with mast cells. Immunocytochemistry and Western blotting ...
Severe asthma is characterized by increased airway smooth muscle (ASM) mass due, in part, to ASM cell growth and contractile protein expression associated with increased protein synthesis. Little is known regarding the combined effects of mitogens and interferons on ASM cytosolic protein synthesis. We demonstrate that human ASM mitogens including PDGF, EGF, and thrombin stimulate protein synthe...
گرایش به سمت استفاده از سیستم های سرویس گرا رو به افزایش است؛ اگرچه ذات بسیار پویای این سیستم ها فرایند راستی آزمایی آنها را در عمل با مشکلات زیادی روبه رو کرده است. راستی آزمایی زمان اجرا اگرچه بیشتر به منظور استفاده در سیستم های حساس به ایمنی طراحی شده است، اما می توان از آن به عنوان روشی جدید در فرایند راستی آزمایی سیستم های سرویس گرا هم بهره برد. در این پروژه فرایند راستی آزمایی زمان اجرای...
Airway smooth muscle (ASM) displays a hyperresponsive phenotype at young age and becomes less responsive in adulthood. We hypothesized that allergic sensitization, which causes ASM hyperresponsiveness and typically occurs early in life, prevents the ontogenetic loss of the ASM hyperresponsive phenotype. We therefore studied whether neonatal allergic sensitization, not followed by later allergen...
