Although small interfering RNA (siRNA) therapy has achieved great progress, unwanted gene inhibition in normal tissues severely limits its extensive clinical applications due to uncontrolled siRNA biodistribution. Herein, a spatially controlled siRNA activation strategy is developed to achieve tumor‐specific siRNA therapy without gene inhibition in the normal tissues. The quaternary ammonium moieties...
Immunotherapy brings great benefits for tumor therapy in clinical treatments but encounters the severe challenge of low response rate mainly because of the immunosuppressive tumor microenvironment. Multifunctional nanoplatforms integrating effective drug delivery and medical imaging offer tremendous potential for cancer treatment, which may play a critical role in combinational immunotherapy to overcome...
Immune checkpoint blockade (ICB) is demonstrating great potential in cancer immunotherapy nowadays. Yet, the low response rate to ICB remains an urgent challenge for tumor immunotherapy. A pH and matrix metalloproteinase dual‐sensitive micellar nanocarrier showing spatio‐temporally controlled release of anti‐PD‐1 antibody (aPD‐1) and paclitaxel (PTX) in solid tumors is prepared to realize synergistic...
The prototypical neurotrophin, nerve growth factor (NGF), plays an important role in the development and maintenance of many neurons in both the central and peripheral nervous systems, and can promote functional recovery after peripheral nerve injury in adulthood. However, repair of peripheral nerve defects is hampered by the short half-life of NGF in vivo, and treatment with either NGF alone or NGF...
Nonfouling materials such as neutral poly(ethylene glycol) (PEG) and zwitterionic poly(sulfobetaine methacrylate) (pSBMA) are ideal biocompatible materials for drug, especially protein drug delivery. The interaction behavior of protein between the nonfouling materials could cause great impact on their future applications, such as controlled release drug delivery systems. In this work, we investigated...
