O21 - The role of DNA damage and repair in allergic airway inflammation
نویسندگان
چکیده
Introduction Extensive DNA damage and inefficient DNA repair might be responsible for some of the pathogenic features in patients suffering from asthma. To determine whether DNA adducts can be used as a “dosimeter” for asthma disease severity, we measured the DNA adducts level in lung of mouse with house dust mite (HDM)induced allergic airway inflammation, as the disease progresses. Apoptosis of airway epithelial cells is one of the most critical pathophysiological factors in the development of chronic asthma. As repairing of DNA lesions is important in preventing apoptosis, we propose that DNA repair plays an important pathophysiologic role in regulating lung epithelial cell DNA damage response.

P113: Inflammation and its Role in Neurological Diseases with an Emphasis on MS
Inflammation is an important factor in the pathophysiology of neurological diseases and the physiological response of the immune system against internal and external harmful stimuli. Inflammation is the natural response of the body to damage, which leads to the removal of debris from dead cells and infections from damage and tissue repair. In this study, neuropathic inflammation and its role in...
متن کاملInactivated Mycobacterium phlei inhalation ameliorates allergic asthma through modulating the balance of CD4+CD25+ regulatory T and Th17 cells in mice
Objective(s): Th2 response is related to the aetiology of asthma, but the underlying mechanism is unclear. To address this point, the effect of nebulized inhalation of inactivated Mycobacterium phlei on modulation of asthmatic airway inflammation was investigated. Materials and Methods: 24 male BALB/c mice were randomly divided into three groups: control group (Group A), asthma model group (G...
متن کاملOverview of Relationship of Allergic Asthma with Diet and Food Intake
Allergic asthma is the most common acute inflammatory airway disorder and their incidence population has exploded in the last years, being estimated that over 300 million people worldwide have the condition. Here, we present a brief overview of relationship of allergic asthma with diet and food intake. Several studies have shown that most asthma cases are due to an allergic immune response to e...
