Abstract: The cytotoxicity of hPrP[173-195] prion peptide against a neuroblastoma cell model was found independent of its tendency to aggregate over time. Cytosolic and nuclear inclusions of peptide were highlighted by confocal microscopy, suggesting a role as a transcription factor in activating signal transduction pathways involved in cell toxicity.
