Distinct patterns of spread of prion infection in brains of mice expressing anchorless or anchored forms of prion protein

Abstract excerpt

BACKGROUND: In humans and animals, prion protein (PrP) is usually expressed as a glycophosphatidylinositol (GPI)-anchored membrane protein, but anchorless PrP may be pathogenic in humans with certain familial prion diseases. Anchored PrP expressed on neurons mediates spread of prions along axons in the peripheral and central nervous systems. However, the mechanism of prion spread in individuals expressing...
