Inventors include Umetani Sayako; Nakamura Naoto; Nitabaru Tatsuya; and Fukunaga Hirofumi.
The application for the patent was published on September 18, 2026, under issue no. 38/2026.
Abstract: The present invention addresses the problem of providing: a method for delivering a nucleic acid to immune cells and an agent for delivering a nucleic acid to immune cells, which are both capable of delivering the nucleic acid to both an immune cell that has been subjected to an activation treatment and an immune cell that has not been subjected to an activation treatment; and a method for delivering a nucleic acid to immune cells and an agent for delivering a nucleic acid to immune cells, which are both capable of encapsulating a nucleic acid in a simple manner without a dedicated device. The present invention provides a method for delivering a nucleic acid to immune cells, the method comprising: a step A for preparing lipid particles not containing any nucleic acids, by using an ionizable lipid, a non-ionized lipid, and a lipid having a nonionic polymer; a step B for preparing nucleic acid-containing lipid particles by mixing the nucleic acid with the lipid particles not containing any nucleic acids; and a step C for bringing the nucleic acid-containing lipid particles into contact with immune cells (excluding in vivo delivery methods).
