要旨

As one of the most common malignancies, oral squamous cell carcinoma (OSCC) with high rates of invasiveness and metastasis threatens people's health worldwide, while traditional therapeutic approaches have not met the requirement of its cure. Phototherapies including photothermal therapy (PTT) and photodynamic therapy (PDT) have shown great potential for OSCC treatment due to their noninvasiveness or minimal invasiveness, high selectivity and little tolerance. However, PTT or PDT alone makes it difficult to eradicate OSCC and prevent its metastasis and recurrence. Here, double-layered membrane vesicles (DMVs) were extracted from attenuated Porphyromonas gingivalis, one of the most common pathogens inside the oral region, and served as an immune adjuvant to develop a biomimetic phototherapeutic nanoagent named PBAE/IR780@DMV for OSCC treatment via combining dual PTT/PDT and robust antitumor immunity. To obtain PBAE/IR780@DMV, poly(β-amino) ester (PBAE) was used as a carrier material to prepare the nanoparticles for loading IR780, a widely known photosensitizer possessing both PTT and PDT capabilities, followed by surface wrapping with DMVs. Upon 808 nm laser irradiation, PBAE/IR780@DMV exerted strong antitumor effects against OSCC both in vitro and in vivo, via combining PTT/PDT and specific immune responses triggered by tumor-associated antigens and DMVs. Altogether, this study provides a promising biomimetic phototherapeutic nanoagent for comprehensive treatment of OSCC.

Journal of Materials Chemistry A, B & C cover high quality studies across all fields of materials chemistry. The journals focus on those theoretical or experimental studies that report new understanding, applications, properties and synthesis of materials. The journals have a strong history of publishing quality reports of interest to interdisciplinary communities and providing an efficient and rigorous service through peer review and publication. The journals are led by an international team of Editors-in-Chief and Associate Editors who are all active researchers in their fields. Journal of Materials Chemistry A, B & C are separated by the intended application of the material studied. Broadly, applications in energy and sustainability are of interest to Journal of Materials Chemistry A, applications in biology and medicine are of interest to Journal of Materials Chemistry B, and applications in optical, magnetic and electronic devices are of interest to Journal of Materials Chemistry C. More than one Journal of Materials Chemistry journal may be suitable for certain fields and researchers are encouraged to submit their paper to the journal that they feel best fits for their particular article. Example topic areas within the scope of Journal of Materials Chemistry B are listed below. This list is neither exhaustive nor exclusive. Antifouling coatings Biocompatible materials Bioelectronics Bioimaging Biomimetics Biomineralisation Bionics Biosensors Diagnostics Drug delivery Gene delivery Immunobiology Nanomedicine Regenerative medicine & Tissue engineering Scaffolds Soft robotics Stem cells Therapeutic devices image block All articles published in Journal of Materials Chemistry B from 2019 onwards will be indexed in MEDLINE®. Articles that primarily focus on providing insight into the underlying science and performance of biomaterials within a biological environment are more suited to our companion journal, Biomaterials Science.
