【摘要】Regulation of immune responses is particular important in recovery after stroke,traumatic brain injury,and brain infections by inhibiting inflammation and reinstating rescue environment.Gene delivery based immunotherapy appears to have significant therapeutic potential for the treatment of neurological conditions by inhibition of neuroinflammation

mechanisms.However,current gene delivery systems lack desired convenience,efficiency,and safety.Nanocarriers offers an attractive gene delivery system that overcome the immunogenic and long-term oncologic effects of the viral vectors.Using branched PEI lipids with PLGA,we developed a highly efficient core-shell nanoparticle(NP)gene delivery system.These IL-4 plasmid DNA(pIL-4)loaded NPs(pIL-4-NPs)were effectively delivered pIL-4 to the human blood monocytes derived
macrophages(MDM)and
mouse
bone
marrow-derived
macrophages(BMM).Furthermore,pIL-4-NPs quickly escaped lysosomes and entered the nuclei of these cells.In in vitro transfection assays,the
