1. Rie Wakabayashi, Wahyu Ramadhan, Kousuke Moriyama, Masahiro Goto, Noriho Kamiya, Poly(ethylene glycol)-based biofunctional hydrogels mediated by peroxidase-catalyzed cross-linking reactions, Polymer Journal, 10.1038/s41428-020-0344-7, 2020.01, Biofunctional hydrogels prepared by a peroxidase, especially horseradish peroxidase (HRP), serve as an excellent class of materials or platform for the development of cellular scaffolds because their biocompatibility and mild and tunable reaction conditions provide them with desirable properties. In this focus review, we summarize our decade of research into HRP-mediated fabrication of biofunctional hydrogels and their applications, in particular cell culture scaffolds. A brief overview of potential substrates employed in HRP and improvement of the HRP hydrogelation system from the initial step until the hydrogen peroxide removal stage in an effort to meet environmental standards is discussed. We highlight our system and describe its biocompatibility and ability to functionalize molecules to support biofabrication by increasing cellular adhesiveness, retaining growth factor affinity, and finally accelerating the formation of two- and three-dimensional multicellular architectures. In the last section, we outline the adoption of hydrogelation as a self-standing, compartmentalized reaction system, i.e., the use of hydrogel marble to conduct cell-free biosynthesis. We believe that this HRP-mediated hydrogel system offers great potential not only as a cell culture scaffold but also for various biomedical applications..

3. Rie Wakabayashi, Hidetoshi Kono, Shuto Kozaka, Yoshiro Tahara, Noriho Kamiya, Masahiro Goto, Transcutaneous codelivery of tumor antigen and resiquimod in solid-in-oil nanodispersions promotes antitumor immunity, ACS Biomaterials Science and Engineering, 10.1021/acsbiomaterials.9b00260, 2019.04, Cancer vaccines aim to prevent or inhibit tumor growth by inducing an immune response to tumor-associated antigens (TAAs) encoded by or present in the vaccine. Previous work has demonstrated that effective antitumor immunity can be induced using a codelivery system in which nonspecific immunostimulatory molecules are administered together with TAAs. In this study, we investigated the antitumor effects of a solid-in-oil (S/O) nanodispersion system containing a model TAA, ovalbumin (OVA), and resiquimod (R-848), a small molecular Toll-like receptor 7/8 ligand, which induces an antigen-nonspecific cellular immune response that is crucial for the efficacy of cancer vaccines. R-848 was contained in the outer oil phase of S/O nanodispersion. Analysis of OVA and R-848 permeation in mouse skin after application of an R-848 S/O nanodispersion indicated that R-848 rapidly permeated the skin and preactivated Langerhans cells, resulting in efficient uptake of OVA and migration of antigen-loaded Langerhans cells to the draining lymph nodes. Transcutaneous immunization of mice with an R-848 S/O nanodispersion inhibited the growth of E.G7-OVA tumors and prolonged mouse survival to a greater extent than did immunization with an S/O nanodispersion containing OVA alone. Consistent with this observation, antigen-specific secretion of the Th1 cytokine interferon-γand cytolytic activity were both high in splenocytes isolated from mice immunized with R-848 S/O. Our results thus demonstrate that codelivery of R-848 significantly amplified the antitumor immune response induced by antigen-containing S/O nanodispersions and further suggest that S/O nanodispersions may be effective formulations for codelivery of TAAs and R-848 in transcutaneous cancer vaccines..
