Role of DNA damage in the pathogenesis of atherosclerosis

J Cardiol. 2022 Sep 12:S0914-5087(22)00218-0. doi: 10.1016/j.jjcc.2022.08.010. Online ahead of print.ABSTRACTAtherosclerosis is a cause of coronary artery disease, abdominal aortic aneurysm, and stroke. The pathogenesis underlying atherosclerosis is complex but it is clear that inflammation plays a pivotal role. Inflammation in atherosclerosis is triggered by the recognition of intracellular contents released from damaged cells by pattern recognition receptors, and is therefore sterile and chronic. Because the DNA of these cells is damaged, cellular senescence is also involved in this inflammation. Here, we will discuss the emerging evidence of a relationship between DNA damage and inflammation in the pathogenesis of atherosclerosis, with a focus on intracellular events and cell fates that arise following DNA damage. Recent evidence will lead us to potential therapeutic targets and allow us to explore potential preventative and therapeutic strategies.PMID:36109257 | DOI:10.1016/j.jjcc.2022.08.010
