PRNP and neuroblastoma: We have previously reported using liposome-siRNA-peptide complexes (LSPCs) addressed to nicotinic acetylcholine receptor (nAchR)- expressing cells using a short, modified peptide from rabies virus glycoprotein (RVG-9r) to deliver PrP siRNA to neuronal cells in vitro and in vivo and cure neuroblastoma cells chronically infected with prions [73].
