Lipid Nanoparticle Products
Introduction of Lipid Nanoparticles (LNPs)
Lipid Nanoparticles (LNPs) are lipid vesicles with a uniform lipid core, prepared from ionizable/cationic lipids, helper/structural lipid, cholesterol, and PEGylated lipids, with a diameter of around 100 nm. Their unique structure and size give them special physical and chemical properties, making them effective for encapsulating and protecting nucleic acid drugs like mRNA, siRNA, and DNA. LNPs can adhere to negatively charged cell membranes and are taken up by cells via endocytosis, forming endosomes. These mature endosomes fuse with lysosomes, where the acidic environment triggers the protonation of ionizable lipids, giving them a positive charge. This allows LNPs to escape the endosomes and release their nucleic acid cargo into the cytoplasm.
Advantages and Applications of Lipid Nanoparticles
-
High Payload Capacity and Delivery Efficiency: LNPs can effectively encapsulate and protect long nucleic acid drugs, preventing their degradation and premature release during delivery.
-
Surface Modification: By conjugating LNPs with antibodies, peptides, and other ligands, targeted delivery to specific tissues, organs, and cells can be achieved.
-
Nucleic Acid Delivery: LNPs can carry various nucleic acids, including mRNA, siRNA, circular RNA, antisense oligonucleotides, and DNA.
-
Gene Editing: LNPs can be loaded with Cas9 mRNA and sgRNA to prepare CRISPR-LNPs for gene editing applications.
-
CAR-T Therapy: LNPs can facilitate in vivo CAR T cell production by delivering CAR mRNA to lymphocytes, offering efficient delivery, low immunogenicity, and reduced risk of insertional mutagenesis.
-
SORT Technology: Based on traditional four-component lipids, introducing a fifth lipid component enables targeted delivery to specific tissues, organs, and cells.
