Abstract:
Using immunostaining with anti-prion protein (PrP) antiserum, we detected numerous kuru plaques in the brain of a 24-year-old man with Gerstmann-Sträussler-Scheinker syndrome. Immunoreactivity on Western blotting of the protease-resistant PrP fraction from the frozen brain was weak. PrP gene analysis showed substitution of alanine to valine in codon 117 but no substitution in codon 102. As the experimental transmission of the disease to mice was negative, a pathogen of a relatively low infectivity may cause the disease in predisposed family members.
