Supplementary experiment with, by the Royal Veterinary College (RVC), is unravelling some of the mysteries of how prion diseases equivalent to CJD damage brain cells (neurons). The scrutiny, published in the online journal BMC Biology, indicates that the presence of prions critically increases the amounts of cholesterol in neurons which triggers the development of neurodegenerative diseases.

It is widely believed that prions (protein only infectious material) are the occasion of rare progressive neurodegenerative disorders that affect both humans and animals. However, what is not known is how the prions damage neurons. The late-model research by Dr Bate and his colleagues at the RVC demonstrates that infection with prions dramatically raises the amount of free cholesterol within neurons. Studies have recently shown that controlling the cholesterol levels within neurons is decisive in limiting the situation of neurodegenerative diseases such as Alzheimer’s, Parkinson’s, prion diseases, multiple sclerosis, and in one’s dotage dementia.

The amount of above cholesterol in cell membranes is known to affect a bunch of cell functions; the RVC’s research concentrated on the affect of free cholesterol on phospholipase A2; activation of this enzyme is implicated in the depletion of neurons in prion and Alzheimer’s contagion. Past studies by the paper’s authors have shown that phospholipase A2 is sensitive to cholesterol depletion. In the BMC Biology paper the researchers show that prions enhancement free cholesterol in the cell membrane primary to increased activation of phospholipase A2.

“Currently there is microscopic consensus on what is causing the degeneration of neurons in prion bug, in our research we own been able to shed light on this process - although more studies are needed in this area,” said Dr Bate, scientist at the Princess Veterinary College. “By understanding the causes of by which prions check compensation neurons scientists will be skilful to find ways of protecting neurons. Ultimately we aim to find a drug that reduces phospholipase A2 activity and slow the degeneration of prion infected neurons.”
