After a PhD in Physiology, Prof Viscomi entered the mitochondrial medicine field in 2004 as a postdoc in Dr Massimo Zeviani’s lab at the Neurological Institute “C. Besta” in Milan, Italy, where in 2009 he was appointed as a junior group leader. His main research interest since then has been focused on translational aspects with the ultimate goals of clarifying the biological basis of human diseases and developing innovative and effective therapies. To this end, he developed and characterized a panel of animal models of mitochondrial disease to investigate the molecular pathogenesis of the corresponding human syndrome. Building on the knowledge of the mechanisms leading to disease, he developed new therapeutic approaches using both pharmacological and gene therapy strategies. The main achievements of these researches have been (i) the discovery of the pathogenetic mechanism of ethylamalonic encephalopathy (EE), i.e. the accumulation of the powerful cytochrome c oxidase inhibitor hydrogen sulfide (H2S) (Tiranti et al, Nat Med, 2009) (ii) the development of a therapy based on N-acetylcysteine and metronidazole highy effective in the treatment of EE in mice and, most importantly, patients (Viscomi et al, Nat Med, 2010) (iii) the discovery that the stimulation of the PGC1alpha-dependent mitochondriogenic pathway by using either the AMPK agonist AICAR or the NAD+ precursor Nicotinamide Riboside (NR) was effective in ameliorating the phenotype in mouse models of cytochrome c oxidase deficiency (Viscomi et al, Cell Metab, 2011; Cerutti et al, Cell Metab, 2013) (iv) the development of AAV-mediated gene therapy approaches to treat mitochondrial diseases due to accumulation of toxic compounds, such as EE and mitochondrial gastro-intestinal-encephalomyopathy (MNGIE) (Di Meo et al, EMBO Mol Med, 2012; Torres-Torronteras et al, Mol Ther, 2014). More recently, his laboratory has demonstrated the potential of AAV-based gene therapy in other mitochondrial diseases due to defects in nuclear genes (Bottani et al, Mol Ther, 2014, Di Meo et al, Gene Therapy, 2017, Pinheiro et al, Mol Ther, 2020). Finally, in collaboration with Michal Minczuk, MBU, Cambridge, UK, he helped develop an AAV-based approach to correct specific mtDNA mutations through the use of Zinc-finger Nucleases (Gammage et al Nat Med, 2018). These studies constitute proof of fundamental principle for the transfer of these therapies to humans in the years to come.
Other studies that we carried out in my laboratory were aimed at studying the possibility of by-passing respiratory chain defects through the use of alternative oxidases (Dogan et al, Cell Metab, 2018), defining the mechanism by which rapamycin improves the phenotype of various mouse models of mitochondrial disease (Civiletto et al, EMBO Mol Med 2018), and the possibility to shape mitochondrial cristae to correct mitochondrial defects (Civiletto et al, Cell Metab, 2015; Luna-Sanchez et al, Mol Ther, 2020)
Finally, I have collaborated on numerous studies to define the functional role of various disease genes (Signes et al, EMBO Mol Med, 2019, Bottani et al, Mol Ther, 2017, Brunetti et al, EMBO Mol Med 2016).
