At its core, the biological process of translation is where mRNA and peptides fundamentally connect. Messenger RNA (mRNA) molecules are transcribed from DNA and carry the genetic code to ribosomes, the cellular machinery responsible for protein synthesis.RNA and Sulfur Compounds Possibly Created the First Peptides on Earth Ribosomes then "read" the mRNA sequence in three-base codons, recruiting specific amino acids to assemble them into a polypeptide chain, which then folds into a functional protein or peptide. This fundamental process underscores the inherent link between mRNA sequences and the peptides they encode.Method of mRNA Display for Selecting Peptides That Bind ... Understanding translation of mRNA is key to appreciating how peptides are generated within cells.

Beyond the direct encoding of peptides by mRNA, recent scientific endeavors have focused on leveraging peptides as sophisticated carriers for mRNA delivery. Peptides have demonstrated great potential as promising carrier candidates for mRNA delivery due to their high cell membrane permeability and good biocompatibility.RNA and Sulfur Compounds Possibly Created the First Peptides on Earth This is particularly crucial because mRNA itself is prone to enzymatic degradation and exhibits poor cellular uptake due to its large size, negative charge, and hydrophilicity. Peptide-based mRNA vaccines, for instance, are being explored for their ability to deliver mRNA encoding antigens for viral threats like influenza and SARS-CoV-2, as well as for cancer immunotherapy. The development of peptide nanoparticles for systemic mRNA delivery and peptide-functionalized lipid nanoparticles for targeted mRNA delivery represents a significant leap forward in overcoming these delivery challenges. These engineered systems can enhance mRNA transfection efficiency and direct delivery to specific tissues or organs, minimizing off-target effects. For example, research into peptide-encoded organ-selective mRNA delivery using methods like the POST (peptide-encoded organ-selective targeting) method aims to precisely deliver mRNA to extrahepatic organs after systemic administration.

The field of mRNA display has been instrumental in the discovery and optimization of peptides with desired functions, including those that can effectively interact with or deliver mRNA. mRNA display is a robust in vitro selection technique that allows for the selection of peptides and proteins with desired functions from libraries of trillions of possibilities. This technology enables the creation of RNA-peptide fusions allowing for the in vitro selection of specific peptides.作者：CM McCrudden·2023·被引用次数：20—The RALAPeptidecan deliver multiplemRNAin a nanoformulation. The RALA/SME vaccine can be delivered intradermally or intramuscularly. By generating covalent fusions between an mRNA and the peptide or protein that it encodes, researchers can screen vast libraries to identify peptides that bind to specific targets or possess other functional attributes. This has led to advancements in discovering macrocyclic peptide binders and covalent modifiers through mRNA display for the discovery of RNA-targeting cyclic peptides. The optimization of mRNA display for identifying peptides that bind with high affinity to specific targets, such as thymidylate synthase RNA, showcases the power of this technique.
