This rogue prion protein (PrPsc), which may be caused by a genetic mutation or occur spontaneously, can be infectious, stimulating other endogenous normal proteins to become misfolded, forming plaques (see Figure 2.4. 2 ).
WebReplication in prions: Propagation in prions is done by transmitting a misfolded protein state. Upon its entry into a healthy organism, the prion induces the conversion of properly-folded proteins into the disease-associated- prion form. This can then act as a template to guide the misfolding of more proteins into prion form. Suggest Corrections. WebThe prion diseases are characterized by neurodegeneration and lethality. In mammals, prions reproduce by recruiting the normal, cellular isoform of the prion protein (PrPC) …
