摘要
With the global outbreak of SARS-CoV-2, mRNA vaccines became the first type of COVID-19 vaccines to enter clinical trials because of their facile production, low cost, and relative safety, which initiated great advances in mRNA therapeutic techniques. However, the development of mRNA therapeutic techniques still confronts some challenges. First, in vitro transcribed mRNA molecules can be easily degraded by ribonuclease (RNase), resulting in their low stability. Next, the negative charge of mRNA molecules prevents them from direct cell entry. Therefore, finding efficient and safe delivery technology could be the key issue to improve mRNA therapeutic techniques. In this Perspective, we mainly discuss the problems of the existing mRNA-based delivery nanoplatforms, including safety evaluation, administration routes, and preparation technology. Moreover, we also propose some views on strategies to further improve mRNA delivery technology.
