Project Details
We are born with a finite number of cochlear hair cells and neurons and these specialised cell types do not regenerate. In addition, they are susceptible to a number of insults including loud noise, certain anitbiotics, cisplatin and ageing. Hearing loss may also have genetic origins. The aims of this basic research is to generate cochlear sensory cell pheontypes from individuals with known pathologies and compare these to normal phenotypes. The long-term goal of this work is to use it as a platform for personalised medicine involving drug discovery and gene editing. Projects under this research theme involve multi-disciplinary, cross-institutional collaborations between A/Prof Mirella Dottori, A/Prof Alice Pebay, A/Prof Alex Hewitt and Dr Rebecca Lim.
