Professor Tzahor studies cardiac regeneration in mammals with focus on the cardiac microenvironment as a means to improve the regenerative capacity of the heart. He has revealed an important role for the tyrosine kinase receptor ERBB2 in cardiomyocyte proliferation and heart regeneration and found that transient overexpression of activated ERBB2 in adult cardiomyocytes is sufficient to trigger a robust regenerative response in both acute and chronic cardiac injury settings. They have also discovered that the Agrin protein can induce the regeneration of the heart of mammals, and their studies examine the therapeutic effects of Agrin, whose administration in the injured heart of pigs causes a significant regenerative response. These findings will have implications for the improvement of current strategies to treat heart disease in humans.

[Professor Martin Bennett]Martin R Bennett, Division of Cardiovascular Medicine, University of Cambridge, UK Regulation of vascular smooth muscle cell senescence in atherosclerosis Professor Bennett studies the mechanisms underlying vascular smooth muscle cell (VSMC) proliferation and survival, and their defects in disease. His research group has identified the triggers and protective pathways regulating VSMC senescence, its consequences, and its role in vascular disease. The research group’s clinical studies use intracoronary imaging and optical coherence tomography together with biomechanics to determine the types and composition of plaques, the stresses on vulnerable plaques, and whether they predict plaque rupture.
