Membrane-enriched proteome changes and prion protein expression during neural differentiation and in neuroblastoma cells

BMC Genomics, 2017
Background The function of the prion protein, involved in the so-called prion diseases, remains a subject of intense debate and the possibility that it works as a pleiotropic protein through the interaction with multiple membrane proteins is somehow ...

Transcriptomic analysis identifies novel potential biomarkers and highlights cilium-related biological processes in the early stages of prion disease in mice

Prion, 2022
Prion diseases are fatal and irreversible neurodegenerative diseases induced by the pathogenic form of the prion protein (PrPSc), which is converted from the benign form of the prion protein (PrPC).

Synthesis and structural characterization of a mimetic membrane-anchored prion protein [PDF]

, 2006
During pathogenesis of transmissible spongiform encephalopathies (TSEs) an abnormal form (PrPSc) of the host encoded prion protein (PrPC) accumulates in insoluble fibrils and plaques. The two forms of PrP appear to have identical covalent structures, but

Enhanced phosphorylation of PERK in primary cultured neurons as an autonomous neuronal response to prion infection.

PLoS ONE, 2020
Conversion of cellular prion protein (PrPC) into the pathogenic isoform of prion protein (PrPSc) in neurons is one of the key pathophysiological events in prion diseases.

Pathogenic mutations in the hydrophobic core of the human prion protein can promote structural instability and misfolding [PDF]

, 2010
Transmissible spongiform encephalopathies, or prion diseases, are caused by misfolding and aggregation of the prion protein PrP. These diseases can be hereditary in humans and four of the many disease-associated missense mutants of PrP are in the ...

Physiological role of the cellular prion protein [PDF]

Veterinary Research, 2007
The prion protein (PrP) plays a key role in the pathogenesis of prion diseases. However, the normal function of the protein remains unclear. The cellular isoform (PrP(C)) is expressed most abundantly in the brain, but has also been detected in other non-neuronal tissues as diverse as lymphoid cells, lung, heart, kidney, gastrointestinal tract, muscle ...

Volume and energy folding landscape of prion protein revealed by pressure

Brazilian Journal of Medical and Biological Research, 2005
The main hypothesis for prion diseases proposes that the cellular protein (PrP C) can be altered into a misfolded, ß-sheet-rich isoform, the PrP Sc (from scrapie).

The prion protein regulates glutamate-mediated Ca2+ entry and mitochondrial Ca2+ accumulation in neurons [PDF]

, 2017
The cellular prion protein (PrPC) whose conformational misfolding leads to the production of deadly prions, has a still-unclarified cellular function despite decades of intensive research.

Role of Prion protein-EGFR multimolecular complex during neuronal differentiation of human dental pulp-derived stem cells [PDF]

, 2018
Cellular prion protein (PrPC) is expressed in a wide variety of stem cells in which regulates their self-renewal as well as differentiation potential. In this study we investigated the presence of PrPCin human dental pulp-derived stem cells (hDPSCs) and ...
