Current Basic Research Project(s)


The Cardiovascular Sciences laboratories operate the experimental, surgical and instrumentation core which provides development of disease models and or calibrated stress in surviving mice as well as techniques for serial following of cardiovascular function.

The investigators in cardiovascular sciences focus on the cellular and molecular mechanisms of cardiac injury and repair. Our current projects deal primarily with mesenchymal plasticity as it effects various populations of fibroblasts in both scar formation and adverse remodeling. The same technology is being used to extend these observations to the kidney in collaboration with members of the Renal Division. The strategy and technology utilized in the laboratory are primarily focused on exposing immunologic mechanisms and our work has now extended into examining inflammatory-based fibrotic reactions in other organs as well. Our studies indicate that inflammation-based fibrosis involves an interaction between myeloid-derived fibroblasts and fibroblasts arising from endogenous mesenchymal stem cells in the heart. The myeloid fibroblasts are induced by dysregulation of chemokine and cytokine mechanisms associated with chronic inflammation; the mesenchymal stem cell derived fibroblasts arise from functional abnormalities of TGFb signaling. Recent studies suggest both mechanisms exist in the chronic inflammation associated with the aging heart as well as defects in cardiac repair in the aging heart.
