Lipid Nanoparticles for Intracellular Delivery
Introduction
Lipid nanoparticles (LNPs) represent a versatile and highly effective platform for the intracellular delivery of therapeutic agents. With their ability to encapsulate a variety of bioactive molecules, including nucleic acids, proteins, and small-molecule drugs, LNPs have gained significant attention in the biomedical field. The physicochemical properties of these therapeutic cargos necessitate the careful tailoring of LNP carrier systems to ensure efficient and safe delivery. Recent advancements have demonstrated the potential of combinatorial lipid libraries in optimizing LNPs for diverse biomedical applications, from gene therapy to cancer treatment.
Lipid Nanoparticles for Nucleic Acids Delivery
LNPs have revolutionized the delivery of nucleic acids, providing a non-viral alternative with remarkable clinical success. The encapsulation of nucleic acids within LNPs protects them from degradation and facilitates their cellular uptake. Biodegradable LNPs have shown promise in delivering Cas9 mRNA and sgRNA, enabling targeted gene knockout in the liver and other tissues.
Lipid Nanoparticles for Protein Delivery
Protein therapeutics offer the advantage of high specificity and biocompatibility. However, their intracellular delivery poses significant challenges due to their size and susceptibility to degradation. LNPs provide a viable solution by facilitating the transport of proteins across cellular membranes and protecting them from the extracellular environment.
Recent studies have demonstrated the efficacy of bioreducible LNPs in delivering genome-editing proteins like Cre recombinase and Cas9 ribonucleoprotein (RNP) complexes. These LNPs enable precise genome modifications in both in vitro and in vivo settings. Additionally, chalcogen-containing LNPs have been developed to enhance the delivery of these proteins by leveraging the unique properties of elements like selenium, which improve endosomal escape and nuclear localization.
Lipid Nanoparticles for Small Molecule Drugs Delivery
Lipid nanoparticles (LNPs) represent a versatile class of liquid nanoparticles utilized extensively for delivering small-molecule drugs. Composed of lipids akin to those found in cell membranes, LNPs are inherently biocompatible, ensuring minimal harm to the body. LNPs can be tailored with diverse attributes such as size, surface charge, and lipid composition, enabling precise control over drug release and targeting. Moreover, LNPs have gained FDA approval for human use, underscoring their safety and efficacy in therapeutic applications.
