Nanoparticle-mediated delivery of microRNAs-based therapies for treatment of disorders

Pathol Res Pract. 2023 Jul 3;248:154667. doi: 10.1016/j.prp.2023.154667. Online ahead of print.ABSTRACTmiRNAs represent appropriate candidates for treatment of several disorders. However, safe and efficient delivery of these small-sized transcripts has been challenging. Nanoparticle-based delivery of miRNAs has been used for treatment of a variety of disorders, particularly cancers as well as ischemic stroke and pulmonary fibrosis. The wide range application of this type of therapy is based on the important roles of miRNAs in the regulation of cell behavior in physiological and pathological conditions. Besides, the ability of miRNAs to inhibit or increase expression of several genes gives them the superiority over mRNA or siRNA-based therapies. Preparation of nanoparticles for miRNA delivery is mainly achieved through using protocols originally developed for drugs or other types of biomolecules. In brief, nanoparticle-based delivery of miRNAs is regarded as a solution for overcoming all challenges in the therapeutic application of miRNAs. Herein, we provide an overview of studies which used nanoparticles as delivery systems for facilitation of miRNAs entry into target cells for the therapeutic purposes. However, our knowledge about miRNA-loaded nanoparticles is limited, and it is expected that numerous therapeutic possibilities will be revealed for miRNA-loaded nanoparticles in future.PMID:37422972 | DOI:10.1016/j.prp.2023.154667
