Dr Célia Fourrier is a post-doctoral research scientist in the Lysosomal Health in Ageing group, Hopwood Centre for Neurobiology, Lifelong Health Theme, at SAHMRI and an affiliate researcher in the Discipline of Psychiatry, School of Medicine, at the University of Adelaide.
She completed her PhD in Bordeaux, France, where she investigated the role of neuroinflammation in emotional and cognitive alterations associated with obesity under the supervision of Dr Nathalie Castanon. She showed that inflammation, and particularly TNF-α, could be an important target in the treatment of mood disorders in obese individuals (Fourrier et al, 2018; Fernandez de Cossio et al, 2018). In addition, she investigated the effect of nutritional interventions with specific nutrients (i.e. n-3 polyunsaturated fatty acids and antioxidants) on metabolic, mood and cognitive alterations in inflammatory conditions (Larrieu et al, 2014) and on the regulation of inflammatory processes in the brain (Fourrier et al. 2017).
During a first postdoctoral position, under the guidance of Prof Bernhard T Baune in the Discipline of Psychiatry at the University of Adelaide, her research activities encompassed a new approach to personalised psychiatry with a focus on the role of the immune system in psychiatric disorders. From 2017 to 2019, she coordinated a clinical trial that investigated the efficacy of using an antidepressant augmented with an anti-inflammatory medication in the treatment of major depressive disorder.
Célia started a second postdoctoral position at SAHMRI in 2019 under the guidance of Dr Tim Sargeant. Her current research focuses on how the relationships between the immune syste and the lysosomal system can be targeted in neurodegenerative disease such as Alzheimer's disease.
Alzheimer’s disease is a memory-robbing disorder responsible for 60-70% of the 50 million cases of dementia around the world. Although billions of dollars have been spent on developing therapies, there is still no treatment available - over 400 trials aiming to stop disease progression have repeatedly failed to help patients.
Disruptions of the brain immune system have a crucial role in the progression of Alzheimer’s disease. The brain’s immune cells, called microglia, recognise aggregated proteins thought to cause Alzheimer’s disease and engulf and degrade them. In the brains of people who live with Alzheimer’s disease, microglia dysfunction causes the accumulation of those proteins, which triggers inflammation. This inflammation promotes neurodegeneration, leading to cognitive decline and loss of independence. This central role of microglia in Alzheimer’s disease highlights a need for compounds that alter microglia to a more protective phenotype.
My overarching research aim is to develop new treatment strategies that restore this protective function of microglia in the brain of people with Alzheimer’s disease. I do this by simultaneously reducing inflammation and increasing microglia's ability to clear and degrade accumulated material through autophagy, a cellular process that cleanses the cells and keep them healthy.
