OBJECTIVE
Severe asthma comprises heterogeneous phenotypes that share in common a poor response to traditional therapies. Recent and ongoing work with tyrosine kinase inhibitors suggests a potential beneficial role in treatment of severe asthma.
RESULTS
Various receptor and nonreceptor tyrosine
Tyrosine kinases play a critical role in transducing intracellular signals from the receptors. Many receptors do not have intrinsic tyrosine kinase activity, so they rely on cytosolic and/or membrane-associated tyrosine kinases for initial signal generation. The Src and JAK family kinases are
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
The pathogenesis of allergic asthma involves the interplay of inflammatory cells and resident airway cells, and of their secreted mediators including cytokines, chemokines, growth factors and inflammatory mediators. Tyrosine kinase signaling cascades play a critical role in the pathogenesis of
BACKGROUND
Asthma is a chronic inflammatory disease characterized by airways hyperresponsiveness (AHR), reversible airflow obstruction, airway remodeling, and episodic exacerbations caused by air pollutants, such as particulate matter (PM; PM <2.5 μm in diameter [PM(2.5)]) and ozone (O(3)). Spleen
Allergic asthma and rhinitis are prevalent diseases in the modern world, both marked by inflammation of the airways. The spleen tyrosine kinase (Syk) plays a critical role in the regulation of such immune and inflammatory responses. Although Syk is best known as a key component of immunoreceptor
The pathogenesis of allergic asthma involves the interplay of inflammatory cells and airway-resident cells, and of their secreted mediators including cytokines, chemokines, growth factors and inflammatory mediators. Receptor tyrosine kinases are important for the pathogenesis of airway remodeling.
BACKGROUND
Blockade of tyrosine kinase signaling by masitinib, a c-kit/PDGF receptor tyrosine kinase inhibitor, can modulate allergic airway inflammation, but effects on lung mechanics have not been well characterized. We hypothesized masitinib would decrease airway eosinophilia and consequently
Asthma is a disease marked by inflammation of airways with an increasing incidence rate worldwide especially among Asian population. Spleen tyrosine kinase (Syk) is known to be involved in regulation of such inflammation response and thereby rendering its inevitable importance among asthma patients.
Blood level of tyrosine as a new clinical and laboratory indicator has been studied in bacterial asthma patients of advanced age. Tyrosine is known to affect metabolism of glucocorticoid hormones (GHs) thus reflecting GHs status of the body and permitting valid evaluation of the need in
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
The present study was designed to investigate the effects of liver soothing pingchuan formula decoction (LSPF) on experimental asthma in BALB/c mice and explore its potential molecular mechanisms. An animal model of asthma was established in BALB/c mice through sensitization and activation with
OBJECTIVE
To explore the effect of siRNA-mediated inhibition of lymphocyte-specific protein tyrosine kinase (Lck) on pulmonary inflammation in a mouse model of asthma.
METHODS
A total of 32 female BABL/c mice were used in the study. The mouse asthma model was established with ovabumin (OVA), and Lck
OBJECTIVE
To investigate the effects of budesonide (BUD) on the airway remodeling and the expression of Janus protein tyrosine kinases 1 (JAK1) and signal transducer and activator of transcription 6 (STAT6) in asthma.
METHODS
Thirty female Balb/c mice were randomly divided into 3 equal groups:
Occupational asthma due to western red cedar is associated with histamine release from basophils and mast cells on exposure to plicatic acid (PA), but the mechanisms underlying this response remain unclear. Specific kinase inhibitors were used to study the role of tyrosine and serine/threonine
