The Role Of Il-6 In Adenosine-Mediated Pulmonary Fibrosis, Mesias Pedroza May 2011

The Role Of Il-6 In Adenosine-Mediated Pulmonary Fibrosis, Mesias Pedroza

Adenosine is a purinergic signaling molecule that regulates various aspects of inflammation and has been implicated in the pathogenesis of chronic lung diseases. Previous studies have demonstrated that adenosine up-regulates IL-6 production through the engagement of the A2B adenosine receptor in various cell types, including alveolar macrophages. IL-6 is elevated in mouse models and humans with chronic lung disease, suggesting a potential role in disease progression. Furthermore, chronic elevation of adenosine in the lungs of adenosine deaminase deficient (Ada-/-) mice leads to the development of pulmonary inflammation, alveolar destruction, and fibrosis, in conjunction with IL-6 elevation. Thus, it was ...


The Role Of A2b Adenosine Receptor Signaling In Adenosine Dependent Lung Disease, Yang Zhou May 2010

The Role Of A2b Adenosine Receptor Signaling In Adenosine Dependent Lung Disease, Yang Zhou

Chronic lung diseases and acute lung injuries are two distinctive pulmonary disorders that result in significant morbidity and mortality. Adenosine is a signaling nucleoside generated in response to injury and can serve both protective and destructive functions in tissues and cells through interaction with four G-protein coupled adenosine receptors: A1R, A2AR, A2BR, and A3R. However, the relationship between these factors is poorly understood. Recent findings suggest the A2BR has been implicated in the regulation of both chronic lung disease and acute lung injury. The work presented in this dissertation utilized the adenosine deaminase-deficient mouse model and the bleomycin-induced pulmonary injury ...
