Messenger RNA (mRNA) recently emerged asan appealing alternative to treat and prevent diseases rangingfrom cancer and Alzheimer’s disease to COVID-19 withsignifi cant clinical outputs. The in vitro-transcribed mRNAhas been engineered to mimic the structure of natural mRNAfor vaccination, cancer immunotherapy and protein replacementtherapy. In past decades, signifi cant progress has beennoticed in unveiling the molecular pathways of mRNA,controlling its translatability and stability, and its evolutionarydefense mechanism. However, numerous unsolvedstructural, biological, and technical diffi culties hamper thesuccessful implementation of systemic delivery of mRNAfor safer human consumption. Advances in designing and manufacturing mRNA and selecting innovative deliveryvehicles are mandatory to address the unresolved issuesand achieve the full potential of mRNA drugs. Despite thesubstantial eff orts made to improve the intracellular deliveryof mRNA drugs, challenges associated with diverse applicationsin diff erent routes still exist. This study examines thecurrent progress of mRNA therapeutics and advancementsin designing biomaterials and delivery strategies, the existingtranslational challenges of clinical tractability and theprospects of overcoming any challenges related to mRNA.
