Microdomains in the Cardiovascular System

Prof. Viacheslav Nikolaev, PhD is the Director of the Institute of Experimental Cardiovascular Research at the University Medical Center Hamburg-Eppendorf, Germany. He is also a member of the German Center for Cardiovascular Research (DZHK). His main interest is live-cell imaging of cardiac cAMP and cGMP microdomains and their role in heart failure.  Prof. Manuela Zaccolo, MD is the Director of the Burdon Sanderson Cardiac Science Centre and works in the Department of Physiology, Anatomy and Genetics at the University of Oxford. She is interested in the regulatory principles by which intracellular signalling networks achieve the plasticity and context-sensitivity necessary for a cell to function. A central topic of her research is the role of local regulation of cyclic nucleotide signalling in healthy and diseased hearts.
