[The prion hypothesis and the human prion diseases].
Our understanding of the pathogenesis of the transmissible spongiform encephalopathies (TSE) has made terrific headway over the past 40 years and some scientists are even of the opinion that this group of diseases belongs to the neurodegenerative syndromes best understood. On the other hand, the investigation of TSE has led to a multitude of unexpected and surprising results and consequently has initiated impassioned discussions among scientists. Although the human forms of TSE are very rare, the wildfire-like spread of the bovine spongiform encephalopathy (BSE) raises the pressing question as to whether BSE is communicable to humans. This overview summarizes some current hypotheses about the nature of the infectious agent and about the pathogenesis of the damage of the central nervous system.
