Advances in the understanding of circRNAs that influence viral replication in host cells.
Circular RNAs (circRNAs) are non-coding RNAs discovered in recent years, which are produced by back-splicing involving the 3' and 5' ends of RNA molecules. There is increasing evidence that circRNAs have important roles in cancer, neurological diseases, cardiovascular and cerebrovascular diseases, and other diseases. In addition, host circRNAs and virus-encoded circRNAs participate in the body's immune response, with antiviral roles. This review summarizes the mechanisms by which host and viral circRNAs interact during the host immune response. Comprehensive investigations have revealed that host circRNAs function as miRNA sponges in a particular manner, primarily by inhibiting viral replication. Viral circRNAs have more diverse functions, which generally involve promoting viral replication. In addition, in contrast to circRNAs from RNA viruses, circRNAs from DNA viruses can influence host cell migration, proliferation, and apoptosis, along with their effects on viral replication. In summary, circRNAs have potential as diagnostic and therapeutic targets, offering a foundation for the diagnosis and treatment of viral diseases.
期刊介绍：
Medical Microbiology and Immunology (MMIM) publishes key findings on all aspects of the interrelationship between infectious agents and the immune system of their hosts. The journal´s main focus is original research work on intrinsic, innate or adaptive immune responses to viral, bacterial, fungal and parasitic (protozoan and helminthic) infections and on the virulence of the respective infectious pathogens.
MMIM covers basic, translational as well as clinical research in infectious diseases and infectious disease immunology. Basic research using cell cultures, organoid, and animal models are welcome, provided that the models have a clinical correlate and address a relevant medical question.
The journal also considers manuscripts on the epidemiology of infectious diseases, including the emergence and epidemic spreading of pathogens and the development of resistance to anti-infective therapies, and on novel vaccines and other innovative measurements of prevention.
The following categories of manuscripts will not be considered for publication in MMIM:
submissions of preliminary work, of merely descriptive data sets without investigation of mechanisms or of limited global interest,
manuscripts on existing or novel anti-infective compounds, which focus on pharmaceutical or pharmacological aspects of the drugs,
manuscripts on existing or modified vaccines, unless they report on experimental or clinical efficacy studies or provide new immunological information on their mode of action,
manuscripts on the diagnostics of infectious diseases, unless they offer a novel concept to solve a pending diagnostic problem,
case reports or case series, unless they are embedded in a study that focuses on the anti-infectious immune response and/or on the virulence of a pathogen.
