Is amyloid-beta transmissible?

Written by Roisin Conneely

A new study led by researchers at University College London (UCL; London, UK) suggests that amyloid-beta deposits may have been transmitted via contaminated instruments during neurosurgery. The study, published in Acta Neuropathologica details how researchers evaluated the medical records of four individuals who had suffered intracranial bleeds due to amyloid-beta build up in blood vessels of the brain. The team discovered that the individuals had undergone neurosurgery decades earlier as children or teenagers, raising the question of whether amyloid-beta may have been transmitted during these operations, similarly to how prion transmission has been implicated in the development of Creutzfeldt-Jakob disease....
