معرفی
Christine Petit is a Professor at the Collège de France and a leading researcher at the Institut Pasteur and Inserm, where she heads the 'Signaling and Receptors Dynamics' team. Her work focuses on the genetics and molecular physiology of hearing, particularly the identification of genes responsible for hereditary deafness and Usher syndrome. She has pioneered the use of genetic approaches to overcome the limitations of classical biochemical methods in studying the cochlea.
- Education: While specific educational details are not provided in the text, her career trajectory indicates training in genetics and neuroscience, likely including a medical or doctoral degree in France.
Her research has profoundly advanced our understanding of auditory mechanoelectrical transduction, hair cell function, and the molecular basis of deafness. By identifying key proteins such as stereocilin and elucidating the roles of Usher syndrome proteins in hair bundle structure and function, her work has laid the foundation for targeted therapies. She has also contributed to the understanding of presbycusis as having a genetic component linked to early-onset deafness genes.
The recent publications highlight a strong trend toward translational research, particularly in gene therapy for Usher syndrome and other forms of deafness. Her team employs cutting-edge techniques including single-cell transcriptomics, mass spectrometry, and mouse models to dissect molecular complexes and develop precision medicine approaches for hearing loss. The work spans from basic molecular mechanisms to preclinical therapeutic validation.

Christine Petit has supervised numerous researchers and students, contributing to the training of the next generation of scientists in auditory neuroscience. She has secured significant funding through national and European grants, including ERC and RHU programs. Her laboratory has been instrumental in establishing pathophysiological classifications of deafness and developing innovative diagnostic and therapeutic strategies.
Laboratories and Research Teams:
She leads the 'Signaling and Receptors Dynamics' team at the Institut Pasteur, which investigates the molecular mechanisms of hearing. Her research is highly collaborative, involving partnerships with biophysicists, physiologists, and clinicians, including Professor Paul Avan and Dr. Saaid Safieddine. The team is actively engaged in projects such as gene therapy for Usher syndrome (TherapUsher, LIGHT4DEAF), the development of inner ear organoids, and the creation of multiparametric diagnostic tools for hearing loss.
