Biography

Antonella qualified from the Catholic University in Rome with First Class Honours in Medicine. Following the completion of her residency in Neurology in Rome, she moved to the Houston Merritt Clinical Research Centre, Columbia University (New York). Her time in the US was supported by the award of two consecutive postdoctoral fellowships from the Italian National Research Centre and Telethon. In the laboratory of Professor Hirano, Antonella and a colleague discovered the first nuclear gene defect causing mitochondrial DNA (mtDNA) dysfunction. The breakthrough launched the field of altered nucleotide metabolism and mitochondrial disorders. Back in Italy, she worked at the National Institute of Neurology "C. Besta" in Milan in the laboratory of Professor Zeviani, where she developed further her interest in mtDNA maintenance, and identified the cause of another form of mitochondrial genomic instability. 


To advance her scientific skills and wishing to focus on elucidating the processes and factors supporting the mtDNA metabolism, Antonella moved to the MRC Mitochondrial Biology Unit (MBU), in Cambridge, and was awarded a Marie Curie Career Development Fellowship (IEF). Shortly thereafter, Antonella was invited by the then Director of MBU, Professor John Walker, to develop a programme of research, which was approved by the Medical Research Council. Thus, in January 2010 Antonella was appointed to career-track group leader position at MBU and began to address the fundamental question of how the biogenesis of the mitochondrion is achieved and regulated. In 2013 she was awarded an MRC senior non-clinical fellowship to continue to develop the programme of research at the MRC´s Mill Hill Laboratories (former National Institute for Medical Research) in London. 


During the time spent in MRC Institutes Antonella, not only advanced her scientific skill, she also absorbed the MRC ethos of tackling and aiming to unravel fundamental scientific problems of major medical importance. Therefore, with the expectation that her skills and experience could be best applied to solving clinical problems in collaboration with the UK leading neurologists, she joined the UCL Institute of Neurology at the end of 2016. She was promoted to Professor in 2018.

Research Summary

Research in my laboratory focuses on mitochondria - the main energy producing components of the cells. We have a special interest in the processes and factors that maintain the small circles of DNA (mtDNA) in the organelle. Using integrative strategies that combine biochemistry, molecular and cellular biology with ‘omics’ we have identified novel components involved in mtDNA metabolism, discovered several genetic causes of mtDNA diseases and uncovered the underlying disease mechanisms. These studies have lead in recent years to the identification of potential therapeutic approaches, which we are beginning to test in patients and animal models of mtDNA diseases. Our ultimate goal is to develop effective therapies for these devastating disorders.


Furthermore, our detailed analysis of rare genetic disorders has revealed fundamental aspects of cell and organ biology, which have far reaching implications for common human pathologies, especially neuro-muscular degeneration. Therefore, we have recently integrated new research activities that address the role of mtDNA dysfunction in adult-onset neurodegenerative disorders. The long-term goal is to use the insights gained to identify novel treatments that can halt or reverse disease progression.
