 Brief biographical sketch of the Coordinator

Federico Cozzolino was born on October 24, 1952. He received his Degree in Medicine and Residency Degree in Hematology at the University of Florence in Italy. His initial research, performed under the supervision of Prof. R. Di Guglielmo, concerned the clinical and molecular aspects of human Multiple Myeloma. As a post-doc, from 1984 to 1987 he joined the Tumor Immunology Lab at the IST in Genoa, Italy. Then, he was Visiting Professor at the Department of Physiology and Cellular Biophysics of the Columbia University in New York from 1988 to 1990. In 1995, he became Research Director of the Italian National Research Council in Rome, Italy. Since 2005, he is Full Professor at the University of Florence.

Current research interests  

Neurotrophins are cytokines commonly believed to act on neural cells. However, solid evidence demonstrates expression of their specific surface receptors, belonging to the Trk family of Tyrosine Receptor Kinases, on an increasing number of cell types of diverse origin. Such evidence suggested that biological functions of neurotrophins might be exerted on different tissues or organs, possibly even for pharmacologic uses. To the latter purpose, since many years our lab is involved in the identification of small molecules, selected from chemical libraries, able to combine with Trk receptors to either stimulate or inhibit their functional activation, thus generating mimetics or inhibitors of the native cytokines. Being short-range biologic mediators mainly acting in a paracrine fashion, neurotrophins in fact present poor pharmacokinetic properties (e.g., high sensitivity to proteases and inability to pass through the BBB) and quite limited stability. The selected mimetics have been successfully tested for safety and efficacy in numerous experimental models of human diseases, from the ophthalmologic setting to the cardiovascular conditions characterized by Ischemia/Reperfusion damage to the neurodegenerative disorders.

The research activity is run also relying on collaborations with several national and world-wide groups.

Beyond the usual molecular biology and biochemical techniques for manipulation of genes and purification of proteins, the experimental work involves utilisation of cellular techniques for characterization of the Programmed Cell Death processes, e.g., in conditions of oxidative stress, nutrient deprivation or toxic damage. Genetically modified animals are employed to study neurodegenerative diseases. Confocal microscopy, FACS and mass spectrometry are commonly used.
