Abstract

By exploring how bloodborne factors (such as osteocalcin) help to counteract age-related cognitive decline, we identified a primary cilium–autophagy axis that regulates neuronal homeostasis and cognitive resilience. Osteocalcin promotes neuronal autophagy through its receptor GPR158 at the primary cilium; restoring this pathway in aged mice improves age-related cognitive deficits.

恢复神经元的初级纤毛-自噬轴以培养认知弹性。
通过探索血源性因子(如骨钙素)如何帮助对抗与年龄相关的认知衰退,我们发现了一个调节神经元稳态和认知恢复力的初级纤毛自噬轴。骨钙素通过其受体GPR158在初级纤毛上促进神经元自噬;在老年小鼠中恢复这一通路可以改善与年龄相关的认知缺陷。
