Abstract
An amphiregulin-specific double-stranded oligo siRNA structure comprises hydrophilic and hydrophobic compounds bound to the amphiregulin-specific double-stranded oligo siRNA by a simple covalent bond or a linker-mediated covalent bond so as to increase the in vivo stability and intracellular delivery efficiency of the double-stranded oligo siRNA, and to nanoparticles composed of the oligo siRNA structures. The amphiregulin-specific double-stranded oligo siRNA structure can increase the stability of the amphiregulin-specific double-stranded oligo siRNA without impairing the function of the amphiregulin-specific double-stranded oligo siRNA, and at the same time, can efficiently increase the membrane permeability of the double-stranded oligo siRNA. Thus, when the amphiregulin-specific double-stranded oligo siRNA structure is used, the amphiregulin-specific double-stranded oligo siRNA can be efficiently delivered into cells even when it is administered at a relatively low concentration, so that it can be effectively used for the prevention or treatment of respiratory diseases.
