Abstract

The cellular prion protein PrP(C) is the normal counterpart of the scrapie prion protein PrP(Sc), the main component of the infectious agent of transmissible spongiform encephalopathies (TSEs). It is a ubiquitous cell-surface glycoprotein, abundantly expressed in neurons, which constitute the targets of TSE pathogenesis. The presence of PrP(C) at the surface of neurons is an absolute requirement for the development of prion diseases and corruption of PrP(C) function(s) within an infectious context emerges as a proximal cause for PrP(Sc)-induced neurodegeneration. Experimental evidence gained over the past decade indicates that PrP(C) has the capacity to mobilize promiscuous signal transducti..
