Probing the therapeutic potential of TRPC6 for Alzheimer's disease in live neurons from patient-specific iPSCs

摘要

The induced pluripotent stem cells(iPSCs)offer an unprecedented opportunity to model and study Alzheimer's disease(AD)under patient-specific genetic background.The lower expression of transient receptor potential canonical 6(TRPC6)was associated with AD patients,which might be involved in AD pathogenesis.However,the role of TRPC6 that played in AD process still needs more investigation in patient-relevant neurons.In this study,the iPSCs were generated from peripheral blood cells of sporadic AD patients and efficiently differentiated into mature cortical neurons.These sporadic AD-bearing neurons displayed higher lev-els of AD pathological markers A and phospho-tau,but lower levels of TRPC6,than those of control neurons.Treatment of AD neu-rons with TRPC6 protein fragment or agonist inhibited the elevation of A and phospho-tau.Our results in live AD neurons mani-fest that the compromised expression of TRPC6 substantially contributed to A pathology of sporadic AD,suggesting that targeting TRPC6 could help to develop novel therapeutic strategies for the treatments of AD.
