FUNÇÃO

Its primary physiological function is unclear. May play a role in neuronal development and synaptic plasticity. May be required for neuronal myelin sheath maintenance. May promote myelin homeostasis through acting as an agonist for ADGRG6 receptor. May play a role in iron uptake and iron homeostasis. Soluble oligomers are toxic to cultured neuroblastoma cells and induce apoptosis (in vitro) (By similarity). Association with GPC1 (via its heparan sulfate chains) targets PRNP to lipid rafts. Also

Genetic causes and modifiers of prion diseases.

The Lancet. Neurology2026 Feb

Prion diseases are transmissible neurodegenerative diseases caused by misfolding of prion protein (PrP). All inherited prion diseases, including genetic Creutzfeldt-Jakob disease, Gerstmann-Sträussler-Scheinker disease, and fatal familial insomnia, are caused by pathogenic mutations in the prion protein gene (PRNP). The mutation partly dictates age at disease onset and clinical phenotype, presumably by its effects on the misfolding of PrP, but the clinical features can be highly variable even within the same pedigree. In sporadic prion diseases, genetic factors also play pivotal roles, as polymorphisms of PrP affect susceptibility, strain specificity, and disease progression. Additionally, emerging evidence highlights genetic modifiers outside PRNP that regulate disease susceptibility, implicating protein trafficking and lipid metabolism. Because individuals at genetic risk can be identified long before symptom onset, a distinctive opportunity exists for early or even presymptomatic therapeutic intervention. The unequivocal and well understood molecular target that is PrP, together with the development of diagnostic biomarkers, could create a favourable research setting for disease-modifying treatments.

D178N prion protein mutation endows RML prions with new strain properties that do not mimic human genetic prion diseases.

Acta neuropathologica2026 Feb 10

Genetic prion diseases are caused by mutant prion protein (PrP) misfolding, eventually leading to the formation of PrPSc, the infectious prion isoform that propagates by inducing misfolding of native PrP. Different mutations are thought to generate distinct prion strains with unique self-replicating and neurotoxic properties, contributing to the phenotypic diversity of genetic prion diseases. We previously showed that transgenic mice expressing the mouse PrP homologs of the D178N-M129 and D178N-V129 mutations linked to fatal familial insomnia (FFI) and genetic Creutzfeldt-Jakob disease (CJD178) accumulate misfolded, mildly proteinase-K (PK)-resistant PrP in their brains. These mice develop spontaneous neurological illnesses resembling FFI and CJD178, but their diseases have not been found to be transmissible to various mouse lines. In this study, we further assessed their prion propagation potential by inoculating bank voles-shown here to be susceptible to human FFI and CJD178 prions-and by using RT-QuIC. Negative results from both approaches corroborate the idea that these mice do not generate infectious prions. However, when brain homogenates from Tg(FFI) and Tg(CJD) mice were subjected to protein misfolding cyclic amplification with RML PrPSc as a seed, they generated highly PK-resistant mutant prions (RMLFFI and RMLCJD) able to propagate in Tga20 mice overexpressing wild-type PrP. To determine whether these in vitro-converted prions modeled the human diseases better, we examined their transmissibility, biochemical traits, and neuropathological features. Despite successful serial propagation in Tga20 mice, RMLFFI and RMLCJD displayed long incubation times, poor transmissibility to C57BL/6 mice, identical PK-resistant PrP fragments, and distinctive neuropathological changes including large submeningeal and perivascular plaques enriched in endogenous proteolytically shed PrP lacking membrane anchorage. These findings indicate that, regardless of the M129V polymorphism, the D178N mutation imparts novel, stable strain properties to RML that do not recapitulate the features of FFI and CJD178. Our results offer new insights into how genetic PrP mutations influence prion strain characteristics and suggest that spontaneous and templated prionogenesis may follow distinct mechanistic pathways.

Mutant knock-in mice display enhanced susceptibility to pure prion protein fibrils.

The Journal of general virology2026 Feb

Prion diseases manifest clinically in three different forms. Sporadic and infectious forms of prion disease are caused by the conversion of WT, cellular prion protein (PrPC) into its pathogenic conformer (PrPSc). In contrast, genetic forms of prion diseases are caused by mutations in the PrP sequence that promote mutant PrPSc formation. When reconstituted with either polyanionic or lipid cofactors, purified PrPC substrate can be converted in vitro into PrPSc products that display high levels of specific infectivity when inoculated in WT hosts. In contrast, various protein-only PrPSc molecules formed in the absence of cofactors display much lower levels of specific infectivity. Here, we report that protein-only PrPSc molecules with different sequences can induce the formation of proteinase K-resistant PrPSc molecules and spongiform degeneration in the brains of knock-in mice expressing PrP harbouring the pathogenic E200K mutation, but not in hosts expressing WT PrP. These results indicate that the E200K mutation enhances host susceptibility to various protein-only PrPSc fibrils, suggesting fundamental differences in the replication mechanisms of WT versus mutant prions.
