As a transient carrier of information, exogenous mRNA is considered to be a powerful tool to guide a body to produce its own therapeutics. Based on the structural elements of the mRNA, which have an impact on its performance, including potential immunogenicity, efficacy of translation and stability of the molecule. Nowadays, several studies have showed that antibody-encoding, sequence-optimized or unmodified mRNA in LNPs empowered mice model to successfully fight a variety of biological threats, such as toxins, viruses, and tumors, which indicates that mRNA encoded antibodies will have great potential in therapeutic fields, such as cancer, infectious diseases areas.https://www.creativebiolabs.net/mrna-encoded-antibodies_83.htm
