Abstract:
Alzheimer’ s disease ( AD) is one of the most common dementia of neurodegenerative disorders, which results from the deposition of amyloid-beta ( Aβ) and there are no curative treatments for this disease at present.It had been proved that prion protein is the receptor for Aβand it plays a key role in the progress of AD with dual-side effects. Prion protein can not only transfer neurotoxicity to neurons but also protect them from neurotoxicity of Aβ.The polymor-phisms of prion protein encoding gene ( PRNP) affect the AD incubation period and clinical symptoms in humans and other animals.The discovery of PRNP mutational mouse fills the gaps of existing AD mouse models in this research area, which is potential for the studies of pathogenesis, new drugs design and testing aspects.The role and effects of prion protein in AD pathogenesis were summarized in this paper, furthermore, the discovery and utility of PRNP gene mutational mouse in research on AD and/or amyloid diseases were reviewed, and in order to provide some guidance for AD animal model study.
