[Neuropathology of the new variant of Creutzfeldt-Jakob disease].

Identification in the United Kingdom of cases of Creutzfeldt-Jakob disease with clinical, genetic, neuropathological and phenotype characteristics different from those previously reported, together with its relation to bovine spongiform encephalopathy led to the establishment of a new condition known as a new variant of Creutzfeldt-Jakob disease. In this article we describe the neuropathology and immunohistochemistry of the prion protein involved.
