Brief Biographical sketch of the Coordinator
Born: December 27, 1959; Education: 1984 B.A. in Pharmacy. University of Florence, Italy; 1991 Ph.D. Biochemistry, University of Florence, Italy; 1993 Ph.D. Biotechnology, Biotechnology Centre, Cranfield Institute of Technology, Cranfield (GB).
The scientific activity and research interests of Alessandra Modesti focus on studying of proteins, particularly as structural characterization of proteins. The initial approach to proteins has been investigated using the classic molecular biology procedure obtaining recombinant bacteria and yeast S.cerevisiae. Great part of her activity during this first period has been turned to the study of site-directed mutagenesis of residues of the two phosphomonohydrolases. A new strategy for the investigation of proteins has been developed. This approach consists of the use and implementation of modern methodological approach like the Proteomic techniques (2dimentional electrophoresis/mass spectrometry) with the goal of obtaining more information into complex mechanics in order to obtain a molecular anatomy of the cells. A comparative analysis of the proteomic alterations observed in various experimental conditions allows to identify the metabolic and cell signalling mechanisms that are mainly influenced by these events. This information is converted into a detailed and realistic description of the mode of action of each event also using bioinformatics techniques. More recently the main research activities carried-out are focused on the study of redox proteomics and the correlation among oxidative stress with inflammation and peripheral signals.
