Researchers at Newcastle University have revealed the mechanism by which neurons, the nerve cells in the brain and other parts of the body, age.
The research, published today in Aging Cell, opens up new avenues of understanding for conditions where the ageing of neurons are known to be responsible, such as dementia and Parkinson’s disease.
The ageing process has its roots deep within the cells and molecules that make up our bodies. Experts have previously identified the molecular pathway that react to cell damage and stems the cell’s ability to divide, known as cell senescence.
However, in cells that do not have this ability to divide, such as neurons in the brain and elsewhere, little was understood of the ageing process. Now a team of scientists at Newcastle University, led by Professor Thomas von Zglinicki have shown that these cells follow the same pathway.
