Mitochondria are tiny structures within cells, which play a critical role in cellular energy production and metabolism. When these 'powerhouses' malfunction, it can result in chronic illness.
Mitochondrial diseases are a group of genetic disorders that cause damage to cells and tissues in the body and affect up to 1 in 4300 people in the UK. There are currently no preventative treatments for mitochondrial diseases.
Extensive evidence from animal and clinical studies also suggests that defective mitochondria play a critical role in other neurodegenerative diseases, including Alzheimer's and Parkinson's disease.
We are interested in how mitochondria communicate with the surrounding nerve cell, through 'mitochondrial signalling'. We and others have shown that when nerve cells are stressed or damaged, as happens in neurodegenerative disease, mitochondrial signalling pathways are activated.
Excitingly, we can target these pathways to improve the function of nerves, suggesting that targeting mitochondrial signalling pathways might be a way to treat and prevent mitochondrial disease and neurodegenerative diseases such as Alzheimer's and Parkinson's disease.
