Abstract:Herein, a dual‐responsive shape‐transforming charge‐reversal integrated nanomedicine system (DHP@BPP) is developed for the co‐delivery of the photosensitizer pyro pheophorbide‐α (Ppa), anti‐programmed cell death ligand 1 (PD‐L1) peptide (dPPA), and tumor‐associated macrophages (TAMs)‐regulating drug berberrubine (BBR). Hydrophobic Ppa and hydrophilic BBR are linked by matrix metalloproteinase‐2 (MMP‐2) responsive peptide (PMGMRKLVFF) to form BPP. BPP can self‐assemble into spherical nanoparticles with positive… Show more
