Regulatory T Cells in Asthma and Airway Hyperresponsiveness
Regulatory T cells, or Tregs, have been shown to play a major role in reducing Th2 cell proliferation, potentially reducing (often significantly) airway-associated inflammation seen in airway diseases, such as asthma. These cells are characterized as a sub-population of T cells that maintain peripheral tolerance through a variety of biological mechanisms. Although Tregs make up only 5-10% of pe...
متن کاملAttenuation of allergen-induced airway hyperresponsiveness is mediated by airway regulatory T cells.
Understanding the mechanisms involved in respiratory tolerance to inhaled allergens could potentially result in improved therapies for asthma and allergic diseases. Airway hyperresponsiveness (AHR) is a major feature of allergic asthma, thus the aim of the current study was to investigate mechanisms underlying suppression of allergen-induced AHR during chronic allergen exposure. Adult BALB/c mi...
متن کاملReversal of airway hyperresponsiveness by induction of airway mucosal CD4+CD25+ regulatory T cells
An important feature of atopic asthma is the T cell-driven late phase reaction involving transient bronchoconstriction followed by development of airways hyperresponsiveness (AHR). Using a unique rat asthma model we recently showed that the onset and duration of the aeroallergen-induced airway mucosal T cell activation response in sensitized rats is determined by the kinetics of functional matu...
متن کاملAsymptomatic airway hyperresponsiveness: relationships with airway inflammation and remodelling.
To study the physiopathology and significance of asymptomatic airway hyperresponsiveness (AHR), the clinical and bronchial immunohistological parameters were evaluated in subjects with asymptomatic and symptomatic AHR. Asymptomatic subjects with AHR (eight females/two males, no respiratory symptoms, provocative concentration of methacholine causing a 20% fall in forced expiratory volume in one ...
متن کاملRegulatory T cells and regulation of allergic airway disease.
Diseases like asthma have dramatically increased in the last decades. The reasons for the rising prevalence are still controversially discussed. Besides the genetic predisposition a number of different causes are thought to affect the increase of allergies. These include the hygiene hypothesis as well as changes in intestinal microbiota. Allergic airway inflammation is driven by T cells but it ...
