Research summary
Cardiovascular disease is the leading cause of death worldwide and is largely driven by atherosclerotic coronary artery disease (CAD) and myocardial infarction (MI) or heart failure (HF). Numerous mechanical and pharmacologic interventions have been developed for the management of CAD and HF, however, the mortality, morbidity, and associated financial healthcare burden stemming from these pathologies remains unacceptably high. Furthermore, genetic variation and ancestral differences strongly associate with cardiovascular disease onset and pathogenesis. One of the challenges to studying CAD and HF is the heterogeneity in disease and imperfect experimental models. The advent of next generation sequencing has afforded us the opportunity to profile healthy and diseased human tissue to uncover pathogenic cell states and molecular pathways driving disease pathogenesis.

Despite tremendous progress in CAD/HF research, we still have an incomplete understanding of the precise cell states, transcriptional programs, and regulatory mechanism driving CAD and HF. I hypothesize that in CAD and HF, infiltrating immune cells enter the coronary artery and myocardium respectively, differentiate into diverse cell states, and interact with and cause resident stromal cells to de-differentiate into reparative and pathogenic cell states. To test this hypothesis, we will employ a reverse translation paradigm: starting with human tissue, we will leverage single cell multiomics to dissect the genomic, transcriptional, and regulatory landscape in CAD and HF to generate experimentally testable hypothesis. Next, we will test a subset of patient derived hypothesis by perturbing the immune-stromal axis in vitro and in vivo to identify potential therapeutic targets.
