Fig. 3. Peptide-functionalized nanoparticles.
A) Schematic of particle functionalization with CD47-derived “self” peptide for suppressing phagocytosis. B) Total fluorescence quantification by in situ tumor imaging demonstrates increased uptake over time of the peptide-functionalized nanoformulation. C) Schematic of liposome-polycation-DNA nanoparticles incorporated with immunological adjuvant and the HER2/neu-derived peptide being taken up across the cell membrane for anticancer vaccination. D) Survival of mice over 80 days after tumor challenge demonstrates prophylactic efficacy of different nanoformulations. A, B adapted with permission from [58].
