A simple blood test for Creutzfeldt-Jakob Disease and Mad Cow disease is a step closer, following a breakthrough by medical researchers at the University of Melbourne.
\nUsing newly available genetic sequencing scientists discovered cells infected with prions (the infectious agent responsible for these diseases) release particles which contain easily recognised \u2018signature genes\u2019.
\nAssociate Professor Andrew Hill \u2014 from the Department of Biochemistry and Molecular Biology at the Bio21 Institute \u2014 said these particles travel in the blood stream, making a diagnostic blood test a possibility.
\n‘This might provide a way to screen people who have spent time in the UK, who currently face restrictions on their ability to donate blood,’ he said.
\n‘With a simple blood test nurses could deem a prospective donor\u2019s blood as healthy, with the potential to significantly boost critical blood stocks.’
\nMad Cow disease was linked to the deaths of nearly 200 people in Great Britain who consumed meat from infected animals in the late 1980s.
\nSince 2000, the Australia Red Cross Blood Service has not accepted blood from anybody who lived in the UK for more than six months between 1980 and 1996, or who received a blood transfusion in the UK after 1980.
\nLead author Dr Shayne Bellingham said the breakthrough might also help detect other human neurodegenerative diseases, such as Alzheimer\u2019s and Parkinson\u2019s.
\n‘This is an exciting new field where we can test for conditions in the brain and throughout the body, without being invasive,’ he said.
\nThe researchers\u2019 genetic testing focused on a form of cell discharge called exosomes.
\nIf exosomes were infected with prions (the pathogen that causes Creutzfeldt-Jakob Disease and Bovine Spongiform Encephalopathy, commonly known as Mad Cow Disease) they were found to also carry a specific signature of small genes called microRNA\u2019s.\nUniversity of Melbourne<\/link>\n","protected":false},"excerpt":{"rendered":"
