尽管对突触可塑性和记忆形成的分子认识不断增强,但建立有效的分子干预措施来改善记忆和减轻疾病中的记忆缺陷仍然是一个长期存在的挑战。利用长时程增强 (LTP) 需要 N-甲基-D-天冬氨酸受体 (NMDAR) 和 Ca2+/钙调蛋白依赖性蛋白激酶 II α (CaMKIIα) 的事实,我们开发了一种靶向 NMDAR 的体内,并表明海马体内介导的 CaMKIIα 突触后富集可改善情境恐惧记忆。这种分子方法表明有效靶向突触后分子以增强记忆的潜在需求,并为研究健康和疾病中的记忆改善提供了见解。 VHHAN1 在细胞和体内与 NMDA 受体的亚基 GluN1 结合 与 VHHAN1 融合将外源 CaMKIIα 定向到兴奋性突触后区域 VHHAN1 在海马中局部富集 CaMKIIα,改善情境记忆 有效修饰突触分子以改变记忆的潜在需求 生物科学;认知神经科学;神经科学。
The establishment of effective molecular interventions to improve memory and alleviate memory deficits in disease remains a long-standing challenge despite growing molecular understanding of synaptic plasticity and memory formation. Capitalizing on the fact that long-term potentiation (LTP) requires N-methyl-D-aspartate receptors (NMDARs) and Ca2+/calmodulin-dependent protein kinase II alpha (CaMKIIα), we develop an intrabody that targets NMDARs and show that intrabody-mediated postsynaptic enrichment of CaMKIIα in the hippocampus improves contextual fear memory. This molecular approach suggests a potential demand for effective targeting of postsynaptic molecules to enhance memory and provides insights into studying memory improvement in health and disease. VHHAN1 binds to GluN1, a subunit of NMDA receptors, in cells and in vivo Fusion with VHHAN1 orients exogenous CaMKIIα to excitatory postsynaptic regions CaMKIIα local enrichment by VHHAN1 in the hippocampus improves contextual memory Potential demand for effective modifications of synaptic molecules to modify memory Biological sciences; Cognitive neuroscience; Neuroscience.
