Summary

My research aims at providing new therapeutic options for patients suffering from cardiac and peripheral ischaemia. In the era of “regeneration”, I am convinced that work on stem cells should progress together with investigations into the molecular causes of cardiovascular diseases. Hence, my programme focuses on both “causes” and “solutions”. I am part of local, national and international research networks, including the NIHR Bristol BRU in cardiovascular disease, the new British Heart Foundation centre of vascular regenerative medicine (I am its Bristol coordinator) and a Leducq Transatlantic network in vascular microRNA (as the Bristol PI).  I am engaged with several national and international collaborations aimed at improving cardiovascular and stem cell research and training.

My recent research highlights include:

microRNAs as new therapeutic targets and biomarkers

microRNAs are non coding RNAs able to post-transcriptionally inhibit the expression of multiple target genes. For this reason, they can produce profound alteration in the molecular pathways regulating cardiovascular disease and “regeneration”. microRNAs have become extremely popular among biomedical scientists. My laboratory has developed early research in microRNAs regulating angiogenesis and endothelial behaviour in response to ischaemia and diabetes. We are member of a Leducq Transatlantic initiative for research and training in vascular microRNAs ( www.vascularmirnas.com).

Moreover, in within the NIHR Bristol BRU in cardiovascular disease (http://www.ukcrcexpmed.org.uk/BristolCVBRU/Pages/FacilityWelcome.aspx) and the NIHR BRU at the Imperial College of London (where I am a visiting Professor hosted in cardiac surgery by Professor Angelini), we are developing translational microRNAs work aimed at identification of new therapeutic targets in coronary artery disease and thoracic aorta aneurysms and of predictive biomarkers of acute complications of cardiac surgery. My microRNA studies in critical limb ischaemia are currently developed through collaborations in Italy at the UCL and soon (ethical approval pending) expanded to Bristol through collaboration with Mr Marcus Brook (NHS consultant in vascular surgery).

Nerve growth factor (NGF) therapy of ischaemic disease

NGF was the first growth factor to be identified and characterized, a breakthrough discovery for regenerative medicine that valued the Nobel prize to the Italian scientist Professor Rita Levi Montalcini in 1986. As its name suggests, NGF was for a long time studied in the context of neurobiology and neuromedicine. However, several years ago, I have discovered the proangiogenic activity and therapeutic potential of NGF, focussing at that time on limb ischaemia. The British Heart Foundation (BHF) has sponsored my research on the cardiac applications of NGF, first with a Basic Science Lectureship and now with my Senior Research Fellowship. We have so far showed that local NGF gene therapy is able to promote reperfusion, protect cardiomyocytes from death and increase the abundance of stem cells in the infarcted heart (using a mouse model of research) and that it improves post-infarct cardiac function and survival rate. Moreover, NGF gene therapy protects the diabetic heart and kidneys in mice. We have now started a pathway to translate NGF to a first in man trial in patients with coronary artery disease leading to myocardial ischaemia.

Stem cells

Stem cells are the holy grail of both medical scientists and lay persons. Several kinds of stem cells have been proposed for cardiovascular therapies. My laboratory focuses at the most powerful of them, the embryonic stem cells (ESCs). We are improving the process of derivation of vascular progenitor cells from ESCs and trying to better understand their paracrine regenerative properties. Moreover, in collaboration with the Universities of Glasgow and Edinburgh and with the Roslin cells ltd we are developing a pathway to translate clinical grade human ESCs-derived vascular progenitor to a trial in patients with critical limb ischaemia. This would be the very first trial based on ESCs in cardiovascular patients and we are particularly excited. The main collaborator for this work is Professor Andrew Baker, Glasgow. Moreover, I am now expanding to combine pluripotent stem-derived cell products with tissue engineering to be used for correction of congenital heart and thoracic vessel defects during paediatric cardiac surgery (collaboration with Professor Massimo Caputo, paediatric cardiac surgeon).

Biography

I was born in Florence (Tuscany) and studied there to PhD level. I have worked in San Francisco, Ferrara, Rome, Sassari, and Boston before arriving in Bristol in 2005.

Currently, I am a British Heart Foundation (BHF) Senior Research Fellow; Full Professor and Chair of Vascular pathology and Regeneration at the University of Bristol and Visiting Professor at the Imperial College of London. I am also Deputy Head of Research in the School of Clinical Sciences-Bristol. Finally, I am the Bristol coordinator of a BHF centre of Regenerative Medicine, which involves Edinburgh (coordinating centre), Bristol, Glasgow and the KCL.

I am a Fellow of the American Heart Association (FAHA) and part of the editorial boards of Circ Res, ATVB and Vascular Pharmacology. I am Academic Editor for Plos One. I do a lot (possibly too much) of work as a referee for articles and grant applications, including at international level.

I am an internationally leader in the field of vascular biology. My background is in pharmacology (from PhD studies) and therapeutic angiogenesis. I have developed my interest and expertise for angiogenesis and vascular biology under the mentorship of Professor Maurizio Capogrossi in Rome. I had the privilege to be part of the team of Jeff Isner (for the last year of his life as he died prematurely in 2001) in Boston. That was “the lab” if you were interested in reparative angiogenesis by gene and cell therapy, as he was pioneering the field.

I am a PhD scientist. Nonetheless, all of my past mentors were clinical academics and I have always been embedded in clinical institutes. This, which I used to consider a possible limit to my early career as a basic scientist, has later proven a true advantage.  My research is now largely translational. This is facilitated by being located in the Bristol Royal Infirmary (my office and laboratory are indeed inside the hospital) together with my clinical colleagues (especially cardiac surgeons) with interest for research.  The Bristol NIHR BRU in cardiovascular medicine further facilitates the bridging of basic and clinical research interests. Moreover, I have recently taken a visiting professorship at the Imperial College of London, where I work in collaboration with Professor Gianni Angelini and other key persons at the college and at the MRC Clinical Sciences Centre.

                                                                                                               

Teaching

At the University of Bristol, I direct the cardiovascular module (STEM 7) of the master in stem cells and regenerative medicine and I additionally contribute several lecturers to the master in translational cardiovascular medicine.

I supervise several PhD students registered in Bristol as well as visiting PhD students.

I offer summer studentship placement to school VI form students (sponsored by the Nuffield foundation).

Finally, I offer 3 months research projects to undergraduate students.

At international level, I am part of the faculty of the International PhD programme in Biomedical Science (University of Sassari-Italy and University of Hue-Vietnam) and I direct the Stem Cell module of the Master in Medical health biotechnology at university of Hue’-Vietnam.
