In humans, hearing is based on the transformation of sound vibrations into electrical signals. This mechanism takes place in the cells located in the cochlea, which is the inner ear’s sensory organ. These cells are covered in small hairs, hence the name “hair cells”. They are essential and are organized in tufts in which the transformation of the signal involves a network of proteins whose organization is still ill-defined today.

The Usher Syndrome Type II is the leading genetic cause of hearing loss associated with vision loss in patients. Four proteins expressed in a complex are associated with this disease  : ADGRV1, usherin, whirlin and PDZD7. As the molecular organization of this complex is unknown, Prof. Nicolas Wolff intends to elucidate its composition, structure and function in collaboration with Prof. Dorit Hanein, Jean-Philippe Pin and Niels Volkmann.

The results will allow for a better understanding of hearing loss associated with Usher Type II mutations and will be essential in the development of new specific therapeutic approaches.
