Title: A liposome for delivering miRNA using a specific ligand to pancreatic beta cell
Inventor: KIM JI WON
IPC: A61K47/69
Filed: 2018-03-29
Abstract: Provided by the present invention is a liposome nanocarrier carrying miRNA therein and having a surface with which ligand peptide specific to pancreatic beta cells is combined. According to the present invention, the liposome nanocarrier is able to collect miRNA stably when carrying miRNA by containing cationic phospholipid as inner layer phospholipid, and is able to combine beta cell-specific peptide with maleimide as a ligand by including DSPE-PEG2k-maleimide as outer layer phospholipid. The liposome nanocarrier of the present invention can be used beneficially as an active ingredient of a pharmaceutical composition for preventing or treating diabetes using miRNA since the level of miRNA delivery ability is high due to the increase of intake efficiency into beta cells and a targeting ability is not exhibited to other cells besides beta cells when using Ex-4(9-30) peptide of a sequence, from which the N-terminal and C-terminal of exendin-4 are removed, as the beta cell-specific peptide.
