- Original description
Atherosclerosis is the leading cause of acute cardiovascular events, such as myocardial infarction and stroke, and is a significant risk factor for cardiovascular mortality. The detailed understanding of the immune mechanisms and cellular transformations involved in the pathogenesis of atherosclerosis is still limited, and the use of single-cell RNA sequencing (scRNAseq) has revealed new cellular functions and subpopulations associated with disease progression. This study aims to identify cellular subpopulations, molecular pathways, and changes in gene expression related to the development of atherosclerosis in human coronary arteries. Using scRNAseq, the study seeks to characterize the transcriptomic landscape of cells present in atherosclerotic plaques and identify molecular signatures that reveal individual predispositions to specific phenotypes, such as disease susceptibility and response to therapies. The research will be conducted at the Albert Einstein Israeli Hospital in São Paulo and will involve samples from coronary arteries and atherosclerotic plaques of the explanted hearts of patients who have undergone heart transplants as well as from discarded material of coronary artery bypass graft surgery (CABG). With an estimated sample size of 20-30 plaques, the data obtained will allow for a detailed analysis of the molecular mechanisms involved in atherosclerosis, contributing to the development of specific therapeutic targets.Read full original descriptionShow less
