Biological role of Interleukin 33 and its importance in pathophysiology of cardiovascular system
Journal Title: Advances in Hygiene and Experimental Medicine - Year 2014, Vol 68, Issue
Abstract
Interleukin 33 (IL-33) is a member of the IL-1 cytokin family. It is expressed by various cells and tissues, mainly epithelial and endothelial cells. It is a cytokine with dual function. It may act both as a traditional cytokine and as intracellular nuclear factor, functioning as transcription regulator. Its biological effect via interaction with membrane-bound ST2 receptor and IL-1 receptor accessory protein (IL-1RAcP) is associated with the induction of Th2-type immune response and IL-5 and IL-13 synthesis.IL-33 has a strong immunoregulatory properties. Depending on the type of activated cells, microenvironment, and costimulatory factors, IL-33 can act either as a pro- or anti-inflammatory cytokine. Recent studies indicate various protective effect of IL-33/ST2 sygnaling in atherosclerosis, obesity, disorders in glucose homeostasis and in heart diseases. The paper presents current state of knowledge about the structure and biological function of IL-33 and its receptor ST2, with particular emphasis on its role in pathophysiology of cardiovascular system.
