Circular RNAs are single-stranded RNAs which are closed by covalent bonds during splicing. Different from other RNAs, circular RNAs are well known due to their circular structure. In recent years, many researches were conducted to investigate the role of circular RNAs in multiple diseases. To better understand the structure of circular RNAs, we reviewed the biogenesis and related regulation at first. Mechanisms by which circular RNAs exert effects were summarized then. Due to the conserved and brain-specific characteristic, circular RNAs in brain were depicted next. At last, considering the high mortality rate and disability rate caused by stroke globally, we reviewed related articles and summarized the results of original articles. Circular RNAs are suggested to be involved in the pathogenesis of stroke as well as some other neurological diseases which provides new insights and potential targets in clinical application.

Circular RNAs (circRNAs) play pivotal roles in the development and progression of various diseases, including malignant tumors. However, the biological functions and the underlying mechanisms of many circRNAs remain elusive. In this study, we identified a novel circRNA, circTP63-N, generated through the splicing of exons 2-4 of the TP63 gene in nasopharyngeal carcinoma (NPC).

Although promising, dendritic cell (DC) vaccines may not suffice to fully inhibit tumor progression alone, mainly due to the short expression time of the antigen in DC vaccines, immunosuppressive tumor microenvironment, and tumor antigenic modulation. Overcoming the limitations of DC vaccines is expected to further enhance their anti-tumor effects. In this study, we constructed a circRNA-loaded DC vaccine utilizing the inherent stability of circular RNA to enhance the expression level and duration of the antigen within the DC vaccine.

Background: Mitochondria are organelles where energy production takes place via oxidative phosphorylation, thus mitochondrial function influences the organs with large energy consumption, such as the brain. Mitochondria contain their own circular genome (mtDNA), which encodes essential proteins/RNAs involved in oxidative phosphorylation. The maternal inheritance of mtDNA, combined with a higher risk of Alzheimer's disease (AD) observed in females, suggest mtDNA may have a role in AD.

Background: Circular RNA represents a distinctive form of noncoding RNA resulting from back-splicing of exons and introns in mRNA. CircRNA has been shown play important roles in neurological diseases, such as Alzheimer's disease (AD). Some recent studies also have demonstrated circRNA is enriched in the mammal brain and differentially altered during AD.

Background: Circular RNAs (circRNAs) play multifaceted roles to precisely control expression of broad gene networks. These highly stable molecules are often accumulated in the mammalian brain and thought to serve as "memory molecules" that govern the long process of aging. Mounting evidence demonstrated circRNA dysregulation in the postmortem brains of Alzheimer's disease (AD).
