Kuru, the First Human Prion Disease

Paweł P Liberski et al. Viruses. .

Abstract

Kuru, the first human prion disease was transmitted to chimpanzees by D. Carleton Gajdusek (1923⁻2008). In this review, we summarize the history of this seminal discovery, its anthropological background, epidemiology, clinical picture, neuropathology, and molecular genetics. We provide descriptions of electron microscopy and confocal microscopy of kuru amyloid plaques retrieved from a paraffin-embedded block of an old kuru case, named Kupenota. The discovery of kuru opened new vistas of human medicine and was pivotal in the subsequent transmission of Creutzfeldt⁻Jakob disease, as well as the relevance that bovine spongiform encephalopathy had for transmission to humans. The transmission of kuru was one of the greatest contributions to biomedical sciences of the 20th century.

Keywords: Carleton Gajdusek; Kuru; neuropathology; prion diseases.
