[Importance of genetic factors in pathogenesis of subacute spongiform viral encephalitis]
Abstract:
Recently there has been achieved a substantial progress in research concerning pathogenesis of subacute spongiform viral encephalopathies. For this group of disorders, there has been found a common unconventional virus - proteinaceous infectious particle (PrP). There has been recognised a molecular mass, biochemical composition and physicochemical properties of this infectious form. Mutations of scrapie amyloid precursor gene discovered in Gerstmann-Sträussler-Scheinker syndrome (GSS) and familial cases of Creutzfeldt-Jakob disease (CJD) have been revealed. Nowadays examinations in the field of relationships between prion protein and mutations of scrapie precursor gene are continued.
Insights
Researchers have made progress in understanding subacute spongiform encephalopathies, identifying the proteinaceous infectious particle (PrP) as a common cause. Studies are ongoing to explore the link between prion protein and scrapie precursor gene mutations in related disorders.
