Background and specific aims

The biology and pathology of the extracellular matrix is investigated focusing on the alterations occurring on the elastic component of skin and blood vessels during ageing or in acquired and in genetic diseases. Changes in the characteristics of extracellular matrix are known to influence not only the mechanical properties of connective tissue, but also cell phenotype. Therefore, primary cultures of human dermal fibroblasts are investigated to better understand the role of these cells in connective homeostasis in physio-pathological processes (i.e. ageing; hypoxia, serum deprivation); or in acquired (Sclerodermia; Dupuytren) and in genetic diseases [Pseudoxanthoma elasticum (PXE), PXE-like disorders, -Thalassemia]. In particular, the research group is contributing to the understanding of the pathogenesis of PXE, a disease characterized by calcium and phosphate deposition within elastic fibres, (from the discovery of PXE gene to the disclosure of molecules involved in the metabolism of inorganic pyrophosphate).

Other research interests focus on the evaluation of biocompatibility and cytotoxicity parameters for tissue implants and on the characterization of molecular and cellular alterations occurring in different models of cell death after exposure the environmental noxae.
