Asthma is a heterogeneous disorder that results in recurrent attacks of breathlessness, coughing, and wheezing that affects millions of people worldwide. Although the precise causes of asthma are unclear, studies suggest that a combination of genetic predisposition and environmental exposure to various allergens and pathogens contribute to its development. Currently, the most common treatment t...

SINGULAIRiI is a leukotriene receptor antagonist indicated for: . Prophylaxis and chronic treatment of asthma in patients 12 months of age and older (1.1). Acute prevention of exercise-induced bronchoconstriction (EIS) in patients 15 years of age and older (1.2). Relief of symptoms of allergic rhinitis (AR): seasonal allergic rhinitis (SAR) in patients 2 years of age and older, and perennial al...

Respiratory virus infections can trigger exacerbations of asthma and may also contribute to allergic sensitization to aeroallergens and the development of asthma. Conversely, atopy may predispose to more severe virus-induced airway disease. The animal models reviewed in this article support the hypothesis that respiratory virus infections can promote allergic sensitization and the development o...

BACKGROUND Induction of endogenous regulatory T (Treg) cells represents an exciting new potential modality for treating allergic diseases, such as asthma. Treg cells have been implicated in the regulation of asthma, but the anatomic location in which they exert their regulatory function and the mechanisms controlling the migration necessary for their suppressive function in asthma are not known...

Allergic diseases, including asthma and food allergies, are an increasing health concern. Immunotherapy is an effective therapeutic approach for many allergic diseases but requires long dose escalation periods and has a high risk of adverse reactions, particularly in food allergy. New methods to safely induce Ag-specific tolerance could improve the clinical approach to allergic disease. We hypo...

Both nature and induced regulatory T (Treg) lymphocytes are potent regulators of autoimmune and allergic disorders. Defects in endogenous Treg cells have been reported in patients with allergic asthma, suggesting that disrupted Treg cell-mediated immunological regulation may play an important role in airway allergic inflammation. In order to determine whether adoptive transfer of induced Treg c...

IL-6 plays a central role in supporting pathological T(H2) and T(H17) cell development and inhibiting the protective T regulatory cells in allergic asthma. T(H17) cells have been demonstrated to regulate allergic asthma in general and T-bet-deficiency-induced asthma in particular. Here we found an inverse correlation between T-bet and Il-6 mRNA expression in asthmatic children. Moreover, experi...

Asthma is an inflammatory disorder caused by airway exposures to allergens and chemical irritants. Studies focusing on immune, smooth muscle, and airway epithelial function revealed many aspects of the disease mechanism of asthma. However, the limited efficacies of immune-directed therapies suggest the involvement of additional mechanisms in asthmatic airway inflammation. TRPA1 is an irritant-s...

_Background:_ Asthma is an airway disorder where inflammatory cytokines are partly responsible for exacerbating the disease. Interleukin (IL)-32, generally referred to as natural killer cell (NK4) transcript 4, described immunoregulator involved in stimulation of anti-/pro-inflammatory cytokines. The abnormal presence IL-32 has been observed during diseases, particularly asthma. This study aims...
