BACKGROUND Patients with allergic rhinitis and allergic asthma demonstrate comparable local and systemic eosinophil inflammation, and yet they present with different clinical pictures. Less is even known about the contribution of neutrophil inflammation in allergic diseases. The aim of the study was to examine the propensity and selectivity of granule release from primed systemic eosinophils an...

BACKGROUND Cysteinyl leukotrienes (cys-LTs) are very important factors in the pathophysiology of bronchial asthma. Cys-LT receptor antagonists (LTRAs) decrease allergic airway inflammation. The aim of the present study was to determine the differential effects of LTRAs and corticosteroids on allergic airway inflammation and allergen-specific cytokine production from lymphoid tissues using a mur...

Both thymic stromal lymphopoietin (TSLP) and IL-13 are essential cytokines for the development of allergic inflammation. However, a causal link between TSLP and IL-13 has not yet been fully elucidated. This study aimed to investigate whether IL-13 induces TSLP expression and whether the induction contributes to the development of allergic inflammation. We found that IL-13 induced TSLP expressio...

Allergic inflammation is associated with mood disorders, exacerbation of depression, and suicidal behavior. Mediators of inflammation modulate sleep , with Th1 cytokines promoting NREM sleep and increasing sleepiness and Th2 cytokines (produced during allergic inflammation) impairing sleep. As sleep impairment is a rapidly modifiable suicide risk factor strongly associated with mood disorders, ...

BACKGROUND Birch pollen allergic patients frequently experience gastrointestinal upset accompanied by a local allergic inflammation in the small intestine especially during the pollen season. However, it is not known if the GI pathology is connected to the subjective symptoms of the patient. The objective of this study was to evaluate the immune pathology of the duodenal mucosa and the serum Ig...

Influence of a nematode immunomodulator and a nematode infection on two models of allergic disease Parasitic worms, like filariae, have the intriguing capacity to modulate immune responses directed against them, and therefore can persist up to years in a host. This immunomodulation does not only protect the parasite but was found to mediate a negative correlation between infections with parasit...

Asthma is a chronic inflammatory airways disease that usually begins in early life and involves gene-environment interactions. Although most asthma exhibits allergic inflammation, many allergic individuals do not have asthma. Here, we report how the asthma gene a disintegrin and metalloprotease 33 (ADAM33) acts as local tissue susceptibility gene that promotes allergic asthma. We show that enzy...
