To synthesize the physiological functions of normal cellular prion protein across systemic, cellular, and molecular levels to elucidate mechanisms of prion disease pathogenesis.
Synthesized molecular, cellular, and systemic evidence detailing cellular prion protein expression, ligand interactions, and membrane trafficking dynamics.
PrP(C) expression and ligand binding regulate nervous and immune system processes, including memory formation, inflammatory responses, cell proliferation, differentiation, and survival.
PrP(C) activates key signal transduction cascades, including cAMP/protein kinase A, mitogen-activated protein kinase, and phosphatidylinositol 3-kinase/Akt pathways, alongside continuous endocytic recycling.
Functional profiling establishes PrP(C) as a dynamic cell-surface scaffold organizing multi-component signaling modules that translate diverse extracellular signals into systemic physiological responses.
