Title:
LIPID MEMBRANE STRUCTURE FOR DELIVERING NUCLEIC ACID TO WITHIN CELL
Document Type and Number:
WIPO Patent Application WO/2019/103151
Kind Code:
A1
Abstract:
[Problem] The purpose of the present invention is to provide a novel intracellular delivery means for delivering a nucleic acid to within a cell and thereby causing a desired function to be exhibited more efficiently, namely, for delivering a nucleic acid to within an antigen-presenting cell and thereby increasing the antigen presentation strength of a transfected cell. [Solution] Provided is a lipid membrane structure that is for delivering a nucleic acid to within a cell, in which a lipid membrane is modified by at least one polypeptide having 12-50 amino acid residues including at least three K-A-L-A repeating units within the peptide chain thereof (wherein K may be R in one or more of the repeating units, and/or the A sandwiched between K and L may be H in one or more of the repeating units), and wherein a nucleic acid is held on the surface of the lipid membrane structure.
