- 요약Coronaviridae constitute a distinct family of enveloped, single-stranded RNA (ssRNA) viruses that vary broadly in their disease repertoire, from asymptomatic to benign symptoms that cause the "common cold" or severe disease, and host range, restricted to a specific animal species or capable of interspecies transmission. Viruses with ssRNA genomes are notorious for utilizing rapid, often error-prone replication that can result in accelerated viral evolution and the emergence of new viral strains and subvariants. In late 2019, significant evolutionary events led to the emergence of SARS-CoV-2, a distinct coronavirus with high similarity to SARS-CoV, the virus that causes Severe Acute Respiratory Syndrome (SARS) SARS-CoV-2 displayed higher transmissibility and a wide range of symptoms, ranging from asymptomatic cases to severe respiratory damage and pneumonia, which are now collectively described as Coronavirus Disease 2019, or "COVID-19" (since shortened to "COVID"). The rapid replication and heightened transmissibility of SARS-CoV-2 has led to the accumulation of mutations along the genome and the emergence of new SARS-CoV-2 variants7 . Despite the global mobilization to develop vaccines and anti-viral therapies targeting SARS-CoV-2 acute infection, the estimated global death toll of SARS-CoV-2 since its emergence in 2019 is staggering - over 7 million individuals globally, with more than 1.2 million of those reported in the United States.Thanks to previous work on SARS-CoV and other coronaviruses and the collective action of scientists around the world, the interplay between SARS-CoV-2 and human cells during infection is now fairly well characterized, but many aspects of the viral lifecycle remain elusive. As with all scientific inquiry, we are limited by both our technical ability to detect specific phenomena, and by our ability to imagine what we may not yet be able to detect. RNA molecules are often described as a temporary intermediate in the central dogma, wherein DNA is transcribed into RNA in the nucleus, and that RNA is processed, packaged, and transported to the cytoplasm to be translated into proteins. The central dogma emphasizes the protein as the ultimate,functional outcome, yet there is an entire landscape of RNA molecules, such as microRNAs, small interfering RNAs (siRNAs) and long non-coding RNAs (lncRNAs), that are rarely translated but play significant roles in functional pathways. A landmark study in 2012 by Salzman et al. described the endogenous expression of circular RNA molecules (circRNAs) in human tissues9 . Mammalian circRNAs are expressed in a tissue-specific manner by backsplicing mechanisms during RNA processing in the nucleus9 . Depending on the nucleotide sequence contained in each circRNA, they have the potential to interact with and influence many molecules in the cellular environment that modulate metabolism, cell cycle control, transcription and translation, and immune response10,11. Expression of endogenous circRNAs can be altered by viral infections, and some viruses have been shown to express their own circRNA (virus-derived circRNAs, or VcircRNAs)12, illustrating that such functional RNA species are not unique to mammalian viral hosts and are putative components in pathogenic landscapes. The persistent nature of circRNAs and their potential utility during viral infections may shape the way we understand virus-host interactions on a more granular level, and may alter the design of vaccines and therapeutics in the future.
