Title:
LIPID NANOPARTICLES FOR DELIVERING NUCLEIC ACID TO SPLENIC TISSUE, AND METHOD FOR DELIVERING NUCLEIC ACID TO SPLENIC TISSUE USING SAME
Document Type and Number:
WIPO Patent Application WO/2023/190176
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide: lipid nanoparticles for delivering a nucleic acid to splenic tissue, which can improve the efficiency of delivery of a nucleic acid to splenic tissue cells; and a method for delivering a nucleic acid to splenic tissue using the lipid nanoparticles. Provided are: lipid nanoparticles that are used for the delivery of a nucleic acid to splenic tissue, each of the lipid nanoparticles comprising (A) an ionic lipid represented by formula (1), (B) an anionic lipid or a compound represented by formula (2), (C) cholesterol, and (D) dimyristoyl glycerol PEG represented by the formula CH2(OR6)-CH(OR7)-CH2(OR8) (In the formulae, the definitions for the symbols are as described in the description.); and a method for delivering a nucleic acid to splenic tissue using the lipid nanoparticles.
