The rapid raise of obesity prevalence has already constituted a significant health and economic burden on our society as it is a major contributor 15481974 to a variety of chronic diseases such as cardiovascular diseases, metabolic diseases, osteoarthritis, and cancers. However, the effects of obesity on the respiratory system are SMER28 underappreciated. Since the pioneering research studied by Carmargo and his colleagues showing a parallel increase in the prevalence of obesity and asthma, a growing body of epidemiological evidence indicates an increased incidence of asthma in the overweight and obese population [1?]. There are clear effects of obesity on pulmonary function, linked to enormous respiratory diseases such as asthma, chronic obstructive pulmonary disease, sleep apnea and so on. For instance, several studies reported that BMI was associated with an increased risk of developing airwayhyperresponsiveness (AHR), an objective MedChemExpress ZK 36374 marker for asthma [6,7]. In addition, obesity appears to increase asthma severity and influence the response to asthma controller medications [8,9]. However, even though a possible causal association was established between obesity and asthma, the underlying mechanic basis is largely unclear. The influence of obesity on asthma onset involves in a mechanical constraint on respiratory tracts, airway inflammation and organ remodeling. Obesity can alter respiratory function through affecting the thorax, diaphragm and abdominal muscles, which can increase impairment of the gas transport system [10]. Of particular importance is the role of airway inflammation in the development of AHR and asthma. For instance, several studies reported that asthmatic patients have elevated serum immunoglobulin E (IgE) antibody levels [11], increased production of pro-Neonatal Overfeeding and Airway Responsivenessinflammatory cytokines such as tumor necrosis factor-a (TNF-a), and interleukin (IL)-8, IL-4 and IL-13, and significant recruitment of inflammatory cells into bronchoalveolar lavage fluid (BALF) 12926553 and lung tissue [12]. The obese state has been characterized to create systemic low-grade inflammation as indicated by increased inflammatory markers [13]. TNF-a is an important mediators of the inflammatory response in obesity and is highly expressed in infiltrating macrophages and adipocytes,which may also play a role in AHR [12?4]. Chronic airway inflammation may lead to airway remodeling, another central feature of asthma [15]. Features of this remodeling process include epithelial shedding and subsequently results in the.Ation: 10 mg ml21).
