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. WebIn mammals, prions reproduce by recruiting the normal, cellular isoform of the prion protein (PrPC) and stimulating its conversion into the disease-causing isoform (PrPSc).
