What are the molecular determinants that underlie cardiac fibroblast activation and diversification in the context of ischemic injury and heart failure?

We will utilize state of the art single cell and spatial genomic tools in human and mouse to dissect mesenchymal cell heterogeneity and identify cellular and molecular drivers of cardiac fibrosis and cross-talk to immune cells with the ultimate goal to identify novel therapeutic targets for patients suffering from heart failure. We will extend these studies to dissect the genetic pathways that influence the identity, abundance, and function of cardiac fibroblasts in homeostasis and disease by establishing a variation-to-disease validation pipeline that leverages naturally occurring genetic diversity in well characterized, full sequenced mouse strains. Key identified pathways will be validated by CRISPR/Cas9 based modeling in vitro and in vivo.

“We propose that integrative single cell and spatial genomic technologies allow to dissect the cellular heterogeneity of cardiac fibrosis driving mesenchymal cells and their mechanisms of activation to guide the development of novel therapies for patients with heart failure.”
