Extensive investigations have implicated cytokines such as tumour necrosis factor (TNF)-α and interleukin (IL) -1, and IL-6 as contributing to the pathology of ischemia-reperfusion (I/R) injury, since an increase in the production of those cytokines was clinically detected after myocardial infarction and cardiopulmonary bypass surgery. Current evidence indicates that these cytokines are autocrine contributors to myocardial dysfunction and cardiomyocyte necrosis in I/R injury, whereas, earlier evidence also suggest that cytokines have controversial roles in cardiovascular pathophysiology. Accordingly, it becomes vital to better define the mechanisms of action of cytokines as important steps towards the development of effective therapeutic strategies to combat their deleterious effects in ischemia-induced myocardial injury. Since TNF-α, TGF-β1, IL-1, IL-6 and IL-8 have been frequently studied in cardiovascular diseases, especially in I/R heart disease, the purpose of this article is to review the cardiodepressant role of these cytokines and their release in I/R injury.

More about this publication?
  • Cardiovascular & Hematological Disorders - Drug Targets aims to cover all the latest and outstanding developments on the medicinal chemistry, pharmacology, molecular biology, genomics and biochemistry of contemporary molecular targets involved in cardiovascular and hematological disorders e.g. disease specific proteins, receptors, enzymes, genes. Each issue of the journal will contain a series of timely in-depth reviews written by leaders in the field covering a range of current topics on drug targets involved in cardiovascular and hematological disorders. As the discovery, identification, characterization and validation of novel human drug targets for cardiovascular and hematological drug discovery continues to grow; this journal will be essential reading for all pharmaceutical scientists involved in drug discovery and development.
