Impairment of lung function might be related to IL-10 and IFN-γ defective production in allergic children.
Summary of "Impairment of lung function might be related to IL-10 and IFN-γ defective production in allergic children."
A functional defect of T regulatory cells (Tregs) has been proposed as pathogenic mechanism of allergic reaction. Impairment of lung function frequently occurs in children with respiratory allergy. This study aimed at investigating the possible role of IL-10 and IFN-γ on lung function deterioration in allergic children. Forty children with mild asthma, monosensitized to house dust mites, were evaluated and followed-up for 2 years. Spirometry was performed in all children. IL-10 and IFN-γ were evaluated in in vitro experiments. FEV(1), FVC, and FEF(25-75), evaluated as percent of predicted, significantly diminished over time (p<0.0001, p=0.03, and p<0.0001 respectively). There was a strong relationship between changes in spirometric parameters and IL-10 production and between changes in FEV(1) values and IFN-γ production over time. This preliminary study provided evidence that IL-10 and IFN-γ production could be defective in allergic children prone to develop functional impairment.

Medical and Biotech [MESH] Definitions
Infections of the respiratory tract with fungi of the genus ASPERGILLUS. Infections may result in allergic reaction (ALLERGIC BRONCHOPULMONARY ASPERGILLOSIS), colonization in pulmonary cavities as fungus balls (MYCETOMA), or lead to invasion of the lung parenchyma (INVASIVE PULMONARY ASPERGILLOSIS).
Rhinitis, Allergic, Seasonal
Allergic rhinitis that occurs at the same time every year. It is characterized by acute CONJUNCTIVITIS with lacrimation and ITCHING, and regarded as an allergic condition triggered by specific ALLERGENS.
Viruses which enable defective viruses to replicate or to form a protein coat by complementing the missing gene function of the defective (satellite) virus. Helper and satellite may be of the same or different genus.
Receptors present on a wide variety of hematopoietic and non-hematopoietic cell types that are specific for INTERLEUKIN-4. They are involved in signaling a variety of immunological responses related to allergic INFLAMMATION including the differentiation of TH2 CELLS and the regulation of IMMUNOGLOBULIN E production. Two subtypes of receptors exist and are referred to as the TYPE I INTERLEUKIN-4 RECEPTOR and the TYPE II INTERLEUKIN-4 RECEPTOR. Each receptor subtype is defined by its unique subunit composition.
National Heart, Lung, And Blood Institute (u.s.)
Component of the NATIONAL INSTITUTES OF HEALTH. It conducts and supports research program related to diseases of the heart, blood vessels, lung, and blood; blood resources; and sleep disorders. From 1948 until October 10, 1969, it was known as the National Heart Institute. From June 25, 1976, it was the National Heart and Lung Institute. Since October 1997, the NHLBI has also had administrative responsibility for the NIH Woman's Health Initiative.
