Prions are composed largely, if not entirely, of an altered formal (an abnormal isoform) of a normal cellular protein.</P> The known prion diseases of humans and other mammals are:</P> > >Bovine spongiform encephalopathy (BSE) -- also called mad cow disease; the natural hosts are cattle; the prion involved is the BSE prion.
>Creutzfeldt-Jakob disease (CJD) -- the natural hosts are humans; the prion involved is the CJD prion.
>Gerstmann-Straussler-Scheinker syndrome (GSS) -- the natural hosts are humans; the prion involved is the GSS prion.
>Fatal familial insomnia (FFI) -- the natural hosts are humans; the prion involved is the FFI prion.
>Kuru -- the natural hosts are humans; the prion involved is the kuru prion.
>Scrapie -- the natural hosts of this disease are sheep and goats; the prion involved is the scrapie prion.
>Transmissible mink encephalopathy (TME) -- the natural hosts of this disease are mink; the prion involved is the TME prion.
>Chronic wasting disease (CWD) -- the natural hosts of this disease are mule deer, white-tailed deer, black-tailed deer, and elk; the prion involved is the CWD prion.
>Feline spongiform encephalopathy (FSE) -- the natural hosts are cats; the prion involved is the FSE prion.
>Exotic ungulate encephalopathy (EUE) -- the natural hosts are the nyala and greater kudu; the prion involved is the EUE prion.
