(IE) Could Dementia be prevented by restoring and normalizing protein clusters?

Dementia is a disease that impairs memory and decision-making skills. The clean-up of toxic protein clumps could prevent neurodegenerative diseases, according to a new study.

The study was led by researchers from the Queensland Brain Institute. The research team discovered that focusing on the relationship between two key enzymes could prevent dementia. The proteins the researchers studied were the enzyme Fyn and the protein Tau. They studied the area of the brain that causes frontotemporal dementia, a form of brain disorder that forms when parts of the frontal and temporal lobes are damaged, affecting behavior, language and movement.

The study was published in the journal Molecular Psychiatry.

The research team was led by Professor Frederic Meunier and Dr. Ramón Martínez-Mármol of the Queensland Brain Institute. Researchers found that Fyn, an enzyme that plays a significant role in learning and memory, became active when it was immobilized within the synapses – a link between two nerve cells – that connected hubs between neurons, where the enzymes normally communicate.

“Using super-resolution microscopy, we can now see these enzymes individually and in real-time, moving around randomly in live neurons,” said Dr Martínez-Mármol, lead author on the study.
