Long non-coding RNAs (lncRNAs), which are long transcripts without apparent protein-coding roles, interfere with gene expression and signaling events at various stages. Increasing evidence has suggested that lncRNAs function in the regulation of tissue homeostasis and under pathophysiologic conditions. In the nervous system, the expression of lncRNAs has been detected and characterized under normal physiologic conditions and in disease states. Some lncRNAs regulate brain development and synaptic plasticity. In Alzheimer's disease (AD), several lncRNAs have been demonstrated to regulate β-amyloid production/generation, synaptic impairment, neurotrophin depletion, inflammation, mitochondrial dysfunction, and stress responses. This review summarizes data on lncRNA expression and focuses on neural lncRNAs that may function in AD. Although our understanding of lncRNAs remains in its infancy, this review provides insight into the contribution of lncRNAs to AD.
