Summary: A novel drug loading system, Au@Si-N-N-Si@SiO2, was constructed through layer-by-layer assembly. The system utilized core gold nanorods with near-infrared light-responsive photothermal properties, as well as a middle layer that generates free radicals upon heating to trigger drug release. An outer layer of silica was used to prevent drug leakage. The system demonstrated excellent photothermal effect under near-infrared laser irradiation and showed improved antitumor efficiency through NIR-triggered drug release, free radical generation, and photothermal effect.

Summary: A comparison between intramyocardial (IM) injection and intrapericardial cavity (IPC) injection of adult stem cells in hydrogel showed that IPC injection led to better retention and therapeutic benefits, resulting in significant improvement in cardiac function. Furthermore, IPC delivery demonstrated better cellular proliferation, less apoptosis, and improved vascular regeneration in the myocardium. Additionally, IPC injections led to higher rates of MSC-exosome absorption by heart cells, indicating more extensive paracrine activity and showing promise as a solution for the low retention issue of MSCs in the infarcted heart.

Summary: Nanoparticulate formulations of small-molecule drugs can improve the performance of traditional chemo drugs, but the compatibility between drugs and nanocarriers is a challenge. Stimuli-responsive mPEG-PDLLA-drug conjugate-based nanomedicines can overcome this challenge and provide highly efficacious self-assembled nanomedicines. The hydrophobic content of a polymeric prodrug nanomedicine plays an important role in its performance.

Summary: The maintenance of robust ratiometric loading and release kinetics for effective optimization of combination effects of dual therapeutic agents remains challenging. Herein, we report a sequential drug release system based on nanoformulated mutual prodrugs, allowing acid-triggered release of anticancer drugs, paclitaxel and gemcitabine. The sequence of drug release substantially affected the combination effects in various cell lines, and time-staggered release profiles showed enhanced synergistic effects in A549 cells. In vivo assessment in A549 xenograft models confirmed that the best therapeutic effects were obtained with time-staggered release profiles. Our strategy provides a precise control of sequential drug release for optimizing drug combinations in vitro and in vivo.
