报告内容:

  Aging is the key risk factor for neurodegenerative diseases. Accumulating evidence suggests that C/EBPb/AEP signaling drives both Alzheimer’s disease (AD) and Parkinson’s disease (PD) onset and progression. C/EBPb acts as a major transcription factor for AEP (asparagine endopeptidase, also called legumain), and neuronal C/EBPb transgenic mice display gene dose-dependent short lifespan. Deletion of AEP from Thy1-C/EBPb Tg mice extends the lifespan. AEP levels are escalated in the brain in an age-dependent manner, cleaving APP, Tau and -Synuclein (a-Syn) at N585, N368 and N103, respectively, and triggering Abeta amyloids and Tau aggregation and a-Syn inclusions. Knockout of AEP substantially ameliorates AD and PD pathologies in their mouse models, restoring the behavioral functions. Thus, AEP proteolytic cleavage acts upstream of senile plaques and NFT and Lewy body pathologies, laying foundation for the early diagnosis of these devastating diseases. Quantitative SIMOA (single molecule array) methods have been developed for determining serum APP N585, C586 and Tau N368 levels. Early diagnosis of these neurodegenerative diseases will allow us to therapeutically treat or cure these devastating diseases in the future.
