Allergic airway inflammation is associated with activation of innate immune pathways by allergens. Acute exacerbations of asthma are commonly associated with rhinovirus infection. Here we show that, after exposure to house dust mite (HDM) or rhinovirus infection, the E3 ubiquitin ligase midline 1
Allergic asthma is a chronic inflammatory disease characterized by Th2-type inflammation. Although the cellular interactions are now well studied, the intracellular signaling involved in asthma development is still a developing field. Protein tyrosine kinases are one focus of such research and their
BACKGROUND
Microarray data from mouse studies have identified a number of genes to be differentially expressed in allergen-sensitized mice lungs.
OBJECTIVE
Taking leads from these datasets, we attempted to identify novel genes associated with atopic asthma in humans.
METHODS
We performed
We previously reported an association between genetic differences of pediatric asthma subtypes and a short tandem repeat (STR) marker, D9S286. It has been known that the protein-tyrosine phosphatase receptor-type delta (PTPRD) gene is located downstream of D9S286 and that the physical distance
A 67-year-old female was admitted to our hospital with status asthmaticus. Serum alkaline phosphatase (ALP) level was elevated and ALP-linked immunoglobulins (ALP-Igs) were detected by ALP isozyme analysis. Treatment with prednisolone resulted in improvement of her asthmatic symptoms and serum ALP
Allergic asthma is a chronic inflammatory disease that involves a sustained T-helper-2 (Th2) type immune response and the recruitment of inflammatory cells such as lymphocytes, mast cells, and eosinophils to the lung. The complex cellular interactions involved in this disease are dependent on
Protein tyrosine phosphorylation is an important early event in the signal transduction of numerous cell receptors involved in the immune response. The implication of protein tyrosine kinases in allergic asthma is well recognized, but the role of protein tyrosine phosphatases (PTPs) remains poorly
The effects of a newly synthesized docosahexaenoic acid (DHA) derivative, CRBM-0244, on lung inflammation and airway hyperresponsiveness were determined in an in vitro model of TNF-α-stimulated human bronchi and in an in vivo model of allergic asthma. Mechanical tension measurements revealed that
BACKGROUND
Corticosteroid insensitivity is a major barrier of treatment for some chronic inflammatory diseases, such as severe asthma, but the molecular mechanism of the insensitivity has not been fully elucidated. The object of this study is to investigate the role of protein phosphate 2A (PP2A), a
BACKGROUND
The mechanisms driving glucocorticoid (GC) insensitivity in patients with severe asthma are still unknown. Recent evidence suggests the existence of GC-insensitive pathways in airway smooth muscle (ASM) caused by a defect in GC receptor (GRα) function. We examined whether other mechanisms
Asthma is a chronic airway inflammatory disorder which is characterized by reversible airway obstruction, airway hyperresponsiveness and airway inflammation. Oxidative stress has been shown to be strongly associated with most of the features of asthma and leads to accumulation of phosphatidyl
