Chiara di Malta

Chiara di Malta

TIGEM, Naples, Italy

I graduated in 2005 at the University of Naples Federico II. Then I joined the TIGEM as an Open University PhD student, in Andrea Ballabio’s laboratory. My main PhD research project was focused to the study of the mechanisms leading to the neurodegeneration in lysosomal storage disorders (LSDs). I spent more than three years in the United States where I worked at Baylor College of Medicine (Houston) as visiting PhD student. During this period, I also contributed to the identification of the Transcription factor EB (TFEB) as a master regulator of lysosome biogenesis and autophagy. As postdoctoral researcher I discovered a new transcriptional regulation, mediated by TFEB, controlling mTORC1 signaling in response to nutrients. More recently, I demonstrated that this mechanism promotes cystogenesis and tumor growth in Birt-Hogg-Dube’ syndrome, a genetic condition due to loss of function mutations in the gene encoding FLCN, a key player of mTORC1 signaling. I’m an independent investigator at Tigem since January 2021. My research activity is currently supported by Kidney Cancer Association, Worldwide Cancer Research and Telethon foundation.

Dr. Hurley uses structural biology, biophysics, biochemistry, and cell biology approaches to understand the structure and function of cell membranes in health and disease. He is known for his work on the structure and mechanism of the ESCRT membrane scission machinery, coated vesicle and endosome biogenesis, lipid transporters and second messenger systems, and the autophagy core complexes.

Dr. Hurley’s lab currently has four major projects in the general area of mechanistic membrane biology. He has a long-standing interest in the core mechanisms of autophagy, and is currently focusing on the structural and biophysical basis of mitophagy and its role in Parkinson’s Disease. He is investigating the mechanism of membrane scission by ESCRT complexes in the contexts of HIV budding and release from infected cells, autophagy, and membrane repair. In a third project, the hijacking of coated vesicle trafficking by HIV is being worked out by structural, reconstitution, and live cell imaging approaches. Lastly, in the newest project, he is using structural and biochemical approaches to study the roles of the lysosomal GTPase regulatory complexes FLCN-FNIP and C9orf72-SMRC8 in neurodegenerative diseases.

He is board certified in cardiovascular disease and advanced heart failure. He specializes in caring for patients with advanced heart failure, including those who need ventricular assist devices (VADs) or heart transplants.

His research is focsed on the study and treatment of cardiomyopathy. He has contributed to multipe papers demonstrating techniques for the isolation of enriched populations of cardiovascular progenitor cells from pluripotent stem cells and the utility of these cells for modeling cardiovascular disease. Recently, his work has led to the development of a novel gene therapy for Danon disease, a rare cardiovascular disorder associated with severe hypertrophic cardiomyopathy. The treatment is currently being evaluated in a Phase 1 trial. He also performs clinical research in heart failure and have high-impact publications on a variety of topics including cardiac transplant, mechanical circulatory support, palliative care and machine learning.
