A study about about whether proteins implicated in Alzheimer’s disease are capable of spreading through medical procedures
Neurons in the brain. In Alzheimer’s, there are microscopic ‘plaques’ and ‘tangles’ between and within brain cells. http://bit.ly/1dolXS7
Prions are misfolded proteins that trigger misfolding and aggregation of normal proteins and are responsible for some rare diseases such as the mad cow disease in cattle and Creutzfeldt-Jakob disease (CJD) in humans.
Between 1958 and 1985, several individuals who were short in stature were treated with human growth hormone purified from the pituitary glands of cadavers. Following treatment, some of these individuals developed Creutzfeldt-Jakob disease (CJD), a rare and fatal brain disorder.
Although this treatment ceased in 1985, new cases of CJD are still being diagnosed due to its long incubation period. So far, several hundred cases of CJD have been attributed to the prion-contaminated growth hormone injections or prion-exposure during medical procedures such as neurosurgery…
