CV del Prof. Massimo Stefani

 

Massimo Stefani was born in Pisa, on 31/7/1950 and graduated in Biological Sciences at the University of Firenze. Since 1/8/1981 he was researcher at the Department of Biochemistry of the University of Firenze. In 1990 he won a public competition for Full Professor of Biochemistry at the University of Siena. Since 1993 he is full professor of Biochemistry at the University of Firenze (Department of Biochemical Sciences, since 2013 Department of Biomedical Experimental and Clinical Sciences).

His scientific interests have formerly been focused on the study of the structure-function relationships of phosphomonohydrolases, notably acylphosphatases and low Mr phosphotyrosine protein phosphatases. He has formerly organized the laboratory of chemical synthesis of peptides at the Department of Biochemical Sciences of the University of Firenze. His efforts have been principally dedicated to the study of molecular biology issues such as protein folding, misfolding and aggregation of model proteins such as acylphosphatase, HypF-N, beta2 microglobulin Abeta peptides, amylin and prion proteins and to the investigation of the molecular mechanisms underlying amyloid aggregation and the cell biology of aggregate cytotoxicity on living systems. More recently, he focussed his research on the molecular and cellular basis of the protective effects of plant polyphenols, particularly oleuropein aglycone against amyloid diseases. The results of his researches have been reported in over 180 scientific papers published in outstanding international journals and widely cited (around 10000 total citations, over 6000 citations of the 10 most cited articles, ISI data), for an HI value of 46 (ISI). He has deposited three patents (Nr. MI2008A000514 of 27.03.08, PCT Nr. EP2009/053596 of 23/02/2011 and Nr. FI2011A000034 of 02/03/2011) for the use of oleuropein aglycone and its derivatives in the treatment of type II diabetes mellitus and Alzheimer’s disease.

He has collaborated, and presently collaborates with many foreign and Italian researchers, notably Prof. C.M. Dobson, University of Cambridge, Dr. R. Melki, CNRS, Paris, Prof.  Ayouni E.A.  Centre de Biotecnologie de Borj-Cédria, Hammam-Lif, Tunisie, Prof. P. Nordlund, University of Stockholm, Prof. V. Bellotti, University of Pavia, Prof. P. Pucci, University of Napoli, Prof. M. Bolognesi, University of Milano, Prof. A. Gliozzi/A Relini, University of Genova, Prof. P. Viglino, University of Udine, Prof. P. Polverino de Laureto, University of Padoa, Prof. A. Nataliello, University of Milan. He has been, and presently is, responsible of research projects granted by CNR and MIUR (PRIN and FIIRB) as well as partner in projects CNR, UE and MURST PRIN. He has been Director of the Italian Research Center on the Molecular Basis of Neurodegeneration (CIMN) and member of the Centro Interuniversitario di Medicina Molecolare e Biofisica Applicata (CIMMBA) and of the  Centro per lo Studio a Livello Molecolare e Clinico di Malattie Croniche, Infiammatorie, Degenerative Neoplastiche per Sviluppo Nuove Terapie (DENOthe) of the University of Florence. He is leader of a group associated to the Italian CIB and the Italian INBB.

He has been  reviewer of domestic projects (Italian MIUR 2004), member of the referee board of the Italian MIUR (2006) and many foreign projects for granting institutions. He has been president of the ASN Commission  (05/E1) of the Italian MIUR for the year 2014/15. He has been referee of many qualified scientific journal and project evaluator for several international scientific institutions. He has been Executive Editor of the Italian Journal of Biochemistry and member of the Editorial Board of International Journal of Biological Chemistry, Current Proteomics, The Open Biology Journal, Genes & Diseases, International Journal of Medicine and Clinical Research, Archive of Biochemistry and World Journal of Biological Chemistry (WJBC); Editor of the Special Issue on Protein Folding, Misfolding and Aggregation of the Open Biology Journal (2009). He is, or has been, member of the Società Italiana di Biochimica e Biologia Molecolare, the Protein Society, and the ASBMB.

He organized the international meeting HFSP/EU “Protein Phosphatases” and was Co-organizer and member of the Scientific Committee of the V European Symposium of the Protein Society, co-organizer of the EMBO Workshop and Advanced FEBS Course on “Structure of Amyloid Aggregates, Mechanisms of Formation and Dysfunction”, member of the organizing committee of the 53° Congress of the Società Italiana di Biochimica e Biologia Molecolare, of the scientific committee of the Meeting Proteine 2010 and 2012 of the Società Italiana di Biochimica e Biologia Molecolare and of the XII International Symposium on Amyloidoses (Rome, 2010).
