National Institutes of Health scientists and collaborators at Case Western Reserve University School of Medicine, Cleveland, have detected abnormal prion protein in the skin of nearly two dozen people who died from Creutzfeldt-Jakob disease (CJD). The scientists also exposed a dozen healthy mice to skin extracts from two of the CJD patients, and all developed prion disease. The study results, published in Science Translational Medicine, raise questions about the possible transmissibility of prion diseases via medical procedures involving skin, and whether skin samples might be used to detect prion disease. Researchers from NIH’s National Institute of Allergy and Infectious Diseases (NIAID) were co-leaders of the study, which included multiple collaborating groups. They stress that the prion-seeding potential found in skin tissue is significantly less than what they have found in studies using brain tissue.
