Ischemic heart disease: Cellular and molecular immune contributions of the pericardium

Int J Biochem Cell Biol. 2021 Sep 17:106076. doi: 10.1016/j.biocel.2021.106076. Online ahead of print.ABSTRACTIschemic heart disease promotes complex inflammatory and remodelling pathways which contribute to the development of chronic heart failure. Although blood-derived and local cardiac mediators have traditionally been linked with these processes, the pericardial space has more recently been noted as alternative contributor to the injury response in the heart. The pericardial space contains fluid rich in physiologically active mediators, and immunologically active adipose tissue, which are altered during myocardial infarction. Key immune cells in the pericardial fluid and adipose tissue have been identified which act as mediators for cell recruitment and function after myocardial infarction have been identified in experimental models. Here, we provide an overview of the current understanding of the inflammatory mechanisms of the pericardial space and their role in post-myocardial infarction remodelling and repair and the potential for the use of the pericardial space as a delivery vehicle for treatments to modulate heart healing.PMID:34543760 | DOI:10.1016/j.biocel.2021.106076
