Abstract

Introduction: Cellular prion protein (PrPc) is a normal glycosyl phosphatidylinositol-anchored protein expressed on a wide variety of cell types. Within the CNS, low levels of PrPc are particularly associated with neurons in normal healthy individuals. In contrast, a more pronounced expression of this protein may occur in certain neurodegenerative disorders (Esiri et al. Neuropath Appl Neurobiol 2000; 26: 273; Voigtlander et al. Acta Neuropathol 2001; 101: 417). Overexpression of PrPc has itself been reported to demonstrate neuropathology in transgenic mice (Westaway et al. Cell 1994; 76: 117). The present study investigated whether prion protein is up-regulated in two well-characterized neurodegenerative disorders: Alzheimer's disease (AD) and diffuse Lewy body disease (DLBD).
