要旨

The strategy of using tumor cells to construct whole-cell cancer vaccines has received widespread attention. However, the limited immunogenicity of inactivated tumor cells and the challenge of overcoming immune suppression in solid tumors have hindered the application of whole-cell-based cancer immune therapy. Inspired by the regulatory effects of MnO2 and spatiotemporal control capability of material layers in cell surface engineering, we developed a manganese (Mn)-mineralized tumor cell, B16F10@MnO2, by inactivating B16F10 melanoma cells with KMnO4 to generate manganese-mineralized tumor cells. The cell-based composite was formed by combining amorphous MnO2 with the membrane structure of cells based on the redox reaction between KMnO4 and tumor cells. The MnO2 layer induced a stronger phagocytosis of ovalbumin (OVA)-expressing tumor cells by antigen presenting cells than formaldehyde-fixed cells did, resulting in specific antigen-presentation in vitro and in vivo and subsequent immune responses. Intratumoral therapy with B16F10@MnO2 inhibited B16F10 tumor growth. Moreover, the infiltration of CD8+ T cells within B16F10 solid tumors and the proportion of central memory T cells both increased in B16F10@MnO2 treated tumor-bearing mice, indicating enhanced adaptive immunity. This study provides a convenient and effective method to improve whole-cell-based anti-tumor therapy.

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.
