Abstract:

Small interfering RNAs (siRNAs) therapeutics has advanced into clinical trials for liver diseases and solid tumors, but remain a challenge for manipulating leukocytes fate due to lack of specificity and safety issues. Leukocytes ingest pathogens and defend the body through a complex network. They are also involved in the pathogeneses of inflammation, viral infection, autoimmunity and cancers. Modulating gene expression in leukocytes using siRNAs holds great promise to treat leukocyte-mediated diseases. Leukocytes are notoriously hard to transduce with siRNAs and are spread throughout the body often located deep in tissues, therefore developing an efficient systemic delivery strategy is still a challenge. Here, we discuss recent advances in siRNA delivery to leukocyte subsets such as macrophages, monocytes, dendritic cells and lymphocytes. We focus mainly on lipid nanoparticles (LNPs) comprised of new generation of ionizable lipids and their ability to deliver siRNA to primary or malignant leukocytes in a targeted manner. Special emphasis is made on LNPs targeted to subsets of leukocytes and we detail a novel microfluidic mixing technology that could aid in changing the landscape of process development of LNPs from a lab tool to a potential novel therapeutic modality.
