BACKGROUND Asthmatics in particular have a need for influenza vaccines because influenza infection is a frequent cause of hospitalization of patients with bronchial asthma. Currently, only inactivated influenza vaccines are recommended for influenza prevention in asthma sufferers. OBJECTIVE The aim of our study was to analyze and compare the effects of influenza infection and vaccination with...

BACKGROUND Although the relationship between allergic inflammation and lung carcinogenesis is not clearly defined, several reports suggest an increased incidence of lung cancer in patients with asthma. We aimed at determining the functional impact of allergic inflammation on chemical carcinogenesis in the lungs of mice. METHODS Balb/c mice received single-dose urethane (1 g/kg at day 0) and t...

BACKGROUND Asthma is characterized by chronic airway inflammation, airway hyperresponsiveness (AHR), and airway remodeling. While exposure of house dust mites (HDM) is a common cause of asthma, the pathogenesis of the HDM-induced asthma is not fully understood. Bronchopulmonary C-fibers (PCFs) contribute to the neurogenic inflammation, viral infection induced-persistent AHR, and ovalbumin induc...

OBJECTIVE The Mycobacterium bovis Bacillus Calmette-Guerin (BCG) neonatal vaccination inhibits allergy-induced pathologic changes. However, the mechanisms underlying this process are unclear. This study aimed to investigate the role of interferon (IFN)-γ and interleukin (IL)-17 in the protective effects of the BCG neonatal vaccination on allergic pulmonary inflammation and airway hyperresponsiv...

cytokine production  in response to allergens may influence the development of atopy- predisposing immune responses, initializing the  early programming of  allergy and  asthma. vitamin d  intake  may be  protective  due  to  its  immunoregulatory properties,  that  may contribute  to  influence the expression of  the atopic phenotype  initiated in early life. the objective of our study was to ...

Recent studies suggest that plasminogen activator inhibitor-1 (PAI-1), a major inhibitor of the fibrinolytic system, may promote the development of asthma. To further investigate the significance of PAI-1 in the pathogenesis of asthma and determine the possibility that PAI-1 could be a therapeutic target for asthma, this study was conducted. First, PAI-1 levels in induced sputum (IS) from asthm...

INTRODUCTION A unique anti-interleukin (IL)-13 monoclonal antibody, RPC4046, was generated on the basis of differential IL-13 receptor (R) blockade as assessed in a murine asthma model; the safety, tolerability, pharmacokinetics, and pharmacodynamics of RPC4046 were evaluated in a first-in-human study. METHODS Anti-IL-13 antibodies with varying receptor blocking specificity were evaluated in ...

Asthma, an important public health problem, is a common, potentially serious, medical condition in children, adults and pregnant women. The aim of this study to investigate the effects combined use thymoquinone carob on liver tissue oxidative events, following experimental asthma model. 18 male albino wistar rats were divided into 3 groups as: control group, group treated (A+TQ+C). In asthmatic...

Susceptibility to asthma depends on variation at an unknown number of genetic loci. To identify susceptibility genes on chromosome 7p, we adopted a hierarchical genotyping design, leading to the identification of a 133-kilobase risk-conferring segment containing two genes. One of these coded for an orphan G protein-coupled receptor named GPRA (G protein-coupled receptor for asthma susceptibilit...
