Dementia: Scientists have made a 'promising' discovery – could a cure be in sight?

    One of the hallmarks of neurological disease is the death of brain cells, which causes progressive degeneration of the brain over time. Researchers now believe one brain cell, known as an astrocyte, may play a key role in their death. Studies have shown that these cells release toxic chemicals to which neutrons succumb. This phenomenon, scientists believe, could be the driving factor behind most, if not all, neurodegenerative diseases.

    A team of researchers at the New York University made the breakthrough discovery while conducting a study on mice. 

    The findings, they believe, could pave the way for the development of effective new treatments and help inform preventative measures against the diseases.

    The lead author of the study, Professor Shane Liddelow, said: “Our findings show the toxic fatty acids produced by astrocytes play a critical role in brain cell death.”

    The star-shaped astrocytes had long been known to clear the toxins that accumulate in the brain after head trauma.

    The nature of this removal process was, however, poorly understood. 

    It still remains unclear why astrocytes release toxic chemicals, but researchers have hypothesised that they might evolve to extinguish damaged neurons before they can harm their neighbours. 

    The study, published in Nature, also showed that when the astrocytes were inhibited 75 percent of cells survived, compared to only 10 percent when the cells were left unregulated. 

    The findings have shed light on aspects of the disease which had previously been poorly understood and had held back the development of effective treatments.
