Cellular prion protein and NMDA receptor modulation: protecting against excitotoxicity

open access: yesFrontiers in Cell and Developmental Biology, 2014
Although it is well established that misfolding of the cellular prion protein (PrPC) into the beta-sheet-rich, aggregated scrapie conformation (PrPSc) causes a variety of transmissible spongiform encephalopathies (TSEs), the physiological roles of PrPC ...

Role of the prion protein in copper turnover in astrocytes

open access: yesNeurobiology of Disease, 2004
The prion protein (PrPc) is a glycoprotein that is not only expressed predominantly by neurones but also by other cells, including astrocytes. The recent identification of PrPc as a Cu-binding protein has opened the way to investigating its function in a

Cellular Prion Protein as a Receptor of Toxic Amyloid-β42 Oligomers Is Important for Alzheimer’s Disease

open access: yesFrontiers in Cellular Neuroscience, 2019
The pathological features of Alzheimer’s disease (AD) include senile plaques induced by amyloid-β (Aβ) protein deposits, neurofibrillary tangles formed by aggregates of hyperphosphorylated tau proteins and neuronal cell loss in specific position within ...

Transcriptomic Determinants of Scrapie Prion Propagation in Cultured Ovine Microglia. [PDF]

open access: yesPLoS ONE, 2016
Susceptibility to infection by prions is highly dependent on the amino acid sequence and host expression of the cellular prion protein (PrPC); however, cellular expression of a genetically susceptible PrPC is insufficient.

Dopamine induces the accumulation of insoluble prion protein and affects autophagic flux

open access: yesFrontiers in Cellular Neuroscience, 2015
Accumulation of protein aggregates is a histopathological hallmark of several neurodegenerative diseases, but in most cases the aggregation occurs without defined mutations or clinical histories, suggesting that certain endogenous metabolites can promote

Differentiated cultures of an immortalized human neural progenitor cell line do not replicate prions despite PrPC overexpression

open access: yesPrion, 2023
Prions are misfolded proteins that accumulate within the brain in association with a rare group of fatal and infectious neurological disorders in humans and animals.

Cellular prion protein (PrPC) protects neuronal cells from the effect of huntingtin aggregation [PDF]

open access: yesJournal of Cell Science, 2007
The effect of normal cellular prion protein (PrPC) on abnormal protein aggregation was examined by transfecting huntingtin fragments (Htt) into SN56 neuronal-derived cells depleted of PrPC by RNA interference. PrPC depletion caused an increase in both the number of cells containing granules and the number of apoptotic cells.

The Functional Role of Prion Protein (PrPC) on Autophagy [PDF]

open access: yesPathogens, 2013
Cellular prion protein (PrPC) plays an important role in the cellular defense against oxidative stress. However, the exact protective mechanism of PrPC is unclear. Autophagy is essential for survival, differentiation, development, and homeostasis in several organisms.

Glycosylphosphatidylinositols: More than just an anchor?

open access: yesCommunicative & Integrative Biology, 2016
There is increasing interest in the role of glycosylphosphatidylinositol (GPI) anchors that attach some proteins to cell membranes. Far from being biologically inert, GPIs influence the targeting, intracellular trafficking and function of the attached ...

Engagement of cellular prion protein with the co-chaperone Hsp70/90 organizing protein regulates the proliferation of glioblastoma stem-like cells

open access: yesStem Cell Research & Therapy, 2017
Background Glioblastoma (GBM), a highly aggressive brain tumor, contains a subpopulation of glioblastoma stem-like cells (GSCs) that play roles in tumor maintenance, invasion, and therapeutic resistance.
