Mitophagy Signalling in Health and Disease

In plain English

AI plain-English summary

Every day, the cells in your body are eating their own damaged parts to stay healthy, and this research aims to figure out exactly how that process works. This process, called autophagy, clears out worn-out components like mitochondria. When it fails, it is linked to major diseases including cancer and Parkinson’s. Scientists do not yet understand the molecular machinery that controls autophagy, which makes it impossible to design drugs that could fix it when it goes wrong. This project will map the precise signals and protein interactions that trigger and regulate autophagy at the molecular level. If successful, the work could reveal specific targets for new drugs that restore healthy autophagy in diseased cells. This is fundamental science—there is no immediate clinical application. But similar fundamental discoveries about cellular recycling pathways have already led to experimental treatments for neurodegeneration and cancer. A clearer molecular picture of autophagy could eventually underpin therapies for conditions where cellular waste builds up and causes damage.

View original technical description
The cells of our body are constantly exposed to potentially damaging agents from both external sources, such as the sun's harmful UV rays or pathogenic bacteria, as well as internal sources, including free radicals produced by the cell’s metabolic pathways. A key mechanism that helps us cope with this onslaught is autophagy (which literally means self-eating) whereby damaged and unwanted cellular components, such as mitochondria, are targeted for degradation and recycling. Recent work has indicated that impaired autophagy is linked to many diseases such as cancer and neurodegenerative conditions such as Parkinson’s, therefore any drug that could target this process might be advantageous in treating these diseases. The actual mechanisms of autophagy remain elusive and the aim of my lab is to understand how autophagy is regulated and proceeds at the molecular level. We also aim to unravel how the disruption of autophagic pathways can lead to disease and to exploit this information to develop novel therapeutic strategies.
