Prion protein protects human neurons against Bax-mediated apoptosis.
The function of the cellular prion protein (PrP) is still poorly understood. We present here an unprecedented role for PrP against Bax-mediated neuronal apoptosis and show that PrP potently inhibits Bax-induced cell death in human primary neurons. Deletion of four octapeptide repeats of PrP (PrPDeltaOR) and familial D178N and T183A PrP mutations completely or partially eliminate the neuroprotec...
متن کاملCoenzyme Q10 Protects Hippocampal Neurons against Ischemia/ Reperfusion Injury via Modulation of BAX/Bcl-2 Expression
Introduction: Preliminary studies have con.rmed reduction in cell death following treatment with antioxidants. According to this .nding we study the relationship between consumption of CoQ10 and expression of Bax and Bcl2 in hippocampus following ischemia/reperfusion as proteins involved in cell programmed death or apoptosis. Methods: We studied the protective role of CoQ10 against ischemia-rep...

متن کاملNonpsychoactive cannabidiol prevents prion accumulation and protects neurons against prion toxicity.
Prion diseases are transmissible neurodegenerative disorders characterized by the accumulation in the CNS of the protease-resistant prion protein (PrPres), a structurally misfolded isoform of its physiological counterpart PrPsen. Both neuropathogenesis and prion infectivity are related to PrPres formation. Here, we report that the nonpsychoactive cannabis constituent cannabidiol (CBD) inhibited...
متن کاملMelatonin-mediated β-catenin activation protects neuron cells against prion protein-induced neurotoxicity.
Activation of β-catenin in neurons regulates mitochondrial function and protects against protein misfolding disorders, including Alzheimer's disease and Huntington's disease. Melatonin, a natural secretory product of the pineal gland, exerts neuroprotective effects through the activation of β-catenin. In this study, melatonin increased β-catenin protein expression and activation in human neurob...
