New method to map cholesterol metabolism in brain
A team of researchers led by Swansea University have developed new technology to monitor cholesterol in brain tissue which could uncover its relation to neurodegenerative disease and pave the way for the development of new treatments.
The research, published in the Proceedings of the National Academy of Sciences of the USA, shows the major locations of cholesterol in the brain and what molecules it can be converted to.
The brain is a remarkably complex organ, with cholesterol and its metabolites underpinning the brain's function. Dysregulated cholesterol metabolism is linked to a number of neurodegenerative disorders including Alzheimer's, Parkinson's, Huntington's disease, multiple sclerosis and motor neurone disease.
It is known that cholesterol is not evenly distributed across different brain regions; however, up until now there has been no technology available to map cholesterol metabolism in defined locations of the brain at microscopic levels, and to visualise how it changes in pathological niches in the brain.
