Adenosine A2b Receptor Effects On Post-Mi Remodeling And Cardiac Fibroblast Function, Enbo Zhan

Wayne State University Dissertations

Adenosine A_2B receptor (A_2BR) appear to contribute to chronic inflammation. This receptor is highly expressed in macrophages and cardiac fibroblasts, cells which play key roles in inflammation and healing following myocardial infarction (MI). A_2BR have been shown to induce collagen production and promote organ fibrosis, although the reports of A_2BR role on MI are limited and conflicting. The results of cardiac fibroblast (CF) studies however suggest that non-selective A_2BR stimulation inhibits collagen expression. The hypothesis of the present study was that deletion of A_2BR reduces adverse remodeling in post-MI, …
