Alzheimer's Protein Accidentally Transmitted to Patients Via Discontinued Medical Treatments

Researchers report human growth hormone, prepared from human tissue prior to 1985, may have been contaminated with seeds of the amyloid beta protein. In a new study, researchers injected mice with the original c-hGH batches containing amyloid beta which seeded amyloid pathology, even decades after storage. Findings support the hypothesis that the Alzheimer's causing proteins can be transmitted to from contaminated materials.
