Prion Disease Related Research Tools

Prion diseases, also known as transmissible spongiform encephalopathies (TSEs), are a group of fatal neurodegenerative disorders that include Creutzfeldt-Jakob disease (CJD), Gerstmann-Straussler-Scheinker syndrome, kuru and fatal familial insomnia. Prion diseases are thought to be caused by the misfolding of native cellular prion protein (PrP^C) into the aggregation prone form (PrP^Sc). PrP^Sc refers to the misfolded infectious form that differs from PrP^C because it has a higher content of β-sheet structure and it aggregates to form medium and large size polymers. The conversion of PrP^C into PrP^Sc is the main event in prion disease.

The Central Role of PrP^Sc

There is no doubt that the formation and accumulation of PrP^Sc in the brain is the triggering factor of prion disease. PrP^Sc accumulates in different brain regions as distinct types of deposits depending on the animal species and strains of the agent. The loss of the critical biological function of PrP^C is one possible mechanism by which PrP^Sc formation might result in neurodegeneration. Studies have proposed various functions of PrP^C, such as the roles in apoptosis, oxidative stress, neuroprotection, transmembrane signaling, myelination, cell adhesion, and trafficking of metal ions. Another possible mechanism by which PrP^Sc formation might be linked to the disease is by direct toxicity of the misfolded protein.

Therapeutic Development

Currently, no therapeutic or prophylactic regimens exist for prion diseases. A variety of therapeutic strategies have been proposed but most of them directed at preventing prion conversion. The targets include inhibition of PrP^C expression, enhancement of PrP^C degradation, inhibition of PrP^C-PrP^Sc interaction, inhibition of PrP^Sc oligomer formation, and enhancement of PrP^Sc degradation. PrP^C and PrP^Sc have been widely studied to understand the enigmatic nature of prions. Additionally, some cellular factors have been implicated as possible targets in PrP^C-mediated or PrP^Sc-induced neurodegenerative processes. One example is the growth arrest and DNA-damage-inducible protein GADD34. GADD34 promotes dephosphorylation of the α-subunit of eukaryotic translation initiation factor 2 and reverses translational suppression caused by the prion infection-induced unfolded protein response in the endoplasmic reticulum.
