(awohlkon@vub. ac.be)* These authors contributed equally to this operate.Prion illnesses are related using the conformational conversion in the cellular prion protein (PrPC) into the pathological scrapie isoform (PrPSc) in the brain. Both the in vivo and in vitro conversion of PrPC into PrPSc is drastically inhibited by variations in amino acid sequence amongst the two molecules. Making use of protein misfolding cyclic amplification (PMCA), we now report that the recombinant full-length human PrP (rHuPrP23-231) (that is certainly unglycosylated and lacks the glycophosphatidylinositol anchor) is actually a powerful inhibitor of human prion propagation. Furthermore, rHuPrP23-231 also inhibits mouse prion propagation inside a scrapie-infected mouse cell line. Notably, it binds to PrPSc, but not PrPC, suggesting that the inhibitory effect of recombinant PrP benefits from blocking the interaction of brain PrPC with PrPSc. Our findings suggest a brand new avenue for treating prion ailments, in which a patient’s own unglycosylated and anchorless PrP is applied to inhibit PrPSc propagatio.
