Transmissible spongiform encephalopathies (TSE), or prion diseases, are a group of fatal neurodegenerative disorders of animals and humans. Human diseases include Creutzfeldt-Jakob (CJD) and Gerstmann-Straussler-Scheinker (GSSD) diseases, fatal familial insomnia, and Kuru. Human and animal TSEs share a common histopathology with a pathognomonic...

Glioblastoma multiforme (GBM) is among the most devastating human tumors being rapidly fatal despite aggressive surgery, radiation and chemotherapies. It is characterized by extensive dissemination of tumor cells within the brain that hinders complete surgical resection. GBM tumor initiating-cells (TICs) are a rare subpopulation of cells...

The effects of quinacrine and minocycline on the toxicity induced by hPrP90–231 were studied. By mild thermal denaturation, hPrP90–231 can be converted in a toxic PrPSc-like structure affecting the survival of SH-SY5Y cells. Quinacrine and minocycline prevented hPrP90–231-induced toxicity interfering with different mechanisms: protective...

The aim of this work was to deeply investigate the structure and properties of elec-trochemically synthesized silver nanoparticles (AgNPs) through high-resolution techniques such as transmission electron microscopy (TEM), scanning electron microscopy (SEM), Zeta Potential measurements, and matrix-assisted laser desorption/ionization time of...

The pathological form of prion protein (PrPSc), as other amyloidogenic proteins, causes a marked increase of membrane permeability. PrPSc extracted from infected Syrian hamster brains induces a considerable change in membrane ionic conductance, although the contribution of this interaction to the molecular mechanism of neurodegeneration process...

Quinacrine is one of the few molecules tested to treat patients affected by prion diseases, although the clinical outcome is largely unsatisfactory. To identify novel derivatives with higher neuroprotective activity, we evaluated the effects of a small library of acridine derivatives. The 6-chloro-2-methoxyacridine derivatives bearing on...
