title: [A review of the current research on prions. The evidence suggests the possibility of transmission of the mad cow disease to humans].
abstract: Further evidence of the transmissibility of bovine spongiform encephalopathy (BSE) across the species barrier from cow to man has been derived from epidemiological analysis and the characterisation of prion strains. Recent research has shown the persistence of prions after experimental transmission to resistant murine species, and subclinical persistence in cows. The accumulation of pathological prion proteins in tonsils and appendix has been demonstrated prior to clinical confirmation of the presence of the new variant of Creutzfeldt-Jakob disease. Current prion research is focused on the involvement of B lymphocytes as carriers, on the species barrier and cellular receptors, and on macromolecules involved in the conformational change from normal to pathological prion proteins.
