Dr Michele Miragoli

Dr. Michele Miragoli is a Honorary Research Associate within the Functional Microscopy research group, headed by Dr. Julia Gorelik at National Heart and Lung Institute, Imperial College London, Researcher at the Center of Excellence for Toxicological Research (CERT)  University of Parma, IT and Group Leader in Cardiac Nanophysiology at Humanitas Clinical Center (MIlan, IT).

I studied Science Biology at the University of Parma, Italy. I completed the Ph.D program at the Institute of Physiology in Parma, under the supervision of Prof. Macchi. During the PhD period I was the winner of a scholarship award for advance training period in the foreign country and I chose to go learning the novel technique of optical recording of transmembrane voltage at the most prominent laboratory (Prof. Stephan Rohr’s lab) at Institute of Physiology, University of Bern, Switzerland. After my PhD degree I remained at Rohr’s lab to start a new project related to myofibroblasts and their potential role in cardiac arrhythmia. Our findings suggest that stromal cells in diseased hearts influence the electrophysiology of cardiomyocytes and, thus, may directly affect overall electrical function of the organ. Moreover, our observation that occurrence of arrhythmogenic ectopic activity in cardiac tissue is based not only on defects in the cellular electrophysiology of the cardiomyocytes themselves (the classic view), but that it can be caused by heterocellular electrotonic interactions between cardiomyocytes and other cell types residing in the diseased working myocardium. Those cells might ultimately lead to the identification of new antiarrhythmic therapeutic strategies which are specifically aimed at cells different from cardiomyocytes.

In March 2008 I approached the group of Dr. Gorelik at Imperial College London for combining scanning ion conductance microscopy with my expertise, i.e. optical recording of intracellular calcium and transmembrane voltage. I was enthusiast in working personally for assembling and testing this unique setup. This non-invasive system was operative at the beginning of 2009 and permits to study the characteristics of membrane potential and calcium transient with the live dynamic of cell membrane.

From January 2012 I held the position of group leader in Cardiac Nanophysiology at the CERT -INAIL (University of Parma) and Humanitas Clinical Center , Milan.

The laboratory is interested in cardiac nanophysiology, i.e. the alterations that happen at cellular and subcellular discrete levels in myocardial cells, principally the cardiomyocyte and the fibroblast.
