Fusobacterium nucleatum (F. nucleatum), an oral anaerobe, is prevalent in colorectal cancer and is closely related to increased cancer cell growth, metastasis, and poor treatment outcomes. Bacterial vaccines capable of selectively eliminating bacteria present a promising approach to targeting intratumor F. nucleatum, thereby enhancing cancer treatment. Although adjuvants have been employed to enhance the immune response, the vaccine’s effectiveness is constrained by inadequate T-cell activation necessary for eradicating intracellular pathogens. In this study, we developed a minimalistic, biomimetic nanovaccine by integrating highly immunostimulatory adjuvant cholesterol-modified CpG oligonucleotides into the autologously derived F. nucleatum membranes. Compared to the traditional vaccines consisting of inactivated bacteria and Alum adjuvant, the nanovaccine coupled with bacterial membranes and adjuvants could remarkably improve multiple antigens and adjuvant co-delivery to dendritic cells, maximizing their ability to achieve effective antigen presentation and strong downstream immune progress. Notably, the nanovaccine exhibits outstanding selective prophylactic and therapeutic effects, eliminating F. nucleatum without affecting intratumoral and gut microbiota. It significantly enhances chemotherapy efficacy and reduces cancer metastasis in F. nucleatum-infected colorectal cancer. Overall, this work represents the rational application of bacterial nanovaccine and provides a blueprint for future development in enhancing the antitumor effect against bacterial-infected cancer.

Adhesive hydrogel has drawn great attention for wide applications in wound healing owing to its excellent biocompatibility and lasting adhesiveness. However, traditional adhesive hydrogels only keep the wound moist to promote wound healing. It is still imperative to fabricate adhesive hydrogels that exhibit efficient antibacterial ability, active driving dynamic wound closure, and reactive oxygen species (ROS) scavenging together with excellent mechanical properties. Here, a novel hydrogel based on poly(N-isopropyl acrylamide) (PNIPAAm), a thermoresponsive polymer, and tannic acid (TA)-Ag nanoparticles (TA-Ag NPs) exhibiting active contraction, tissue adhesion, anti-inflammatory and antibacterial functions was developed. TA-Ag dispersed in the hydrogel not only functioned as the catalyst to polymerize the reaction but also provided additional anti-inflammatory and antibacterial properties. Besides, tannic acid containing catechol groups endowed the hydrogel with adhesive ability. More interestingly, the obtained hydrogel exhibited the thermoresponsive shrinkage ability, which could mechanically drive wound closure due to the presence of PNIPAAm network. In vivo mouse full-thickness skin defect model demonstrated that this actively contractible and antibacterial hydrogel is a promising dressing to improve wound healing process by accelerating tissue regeneration and preventing bacterial infection. Therefore, this multi-functional adhesive hydrogel developed here may provide a new possibility for wound healing.

Advanced Functional Materias 2024 Q1IF=18.5

Synthetic biology is propelling medicine into a new era through its capacity to genetically program living cells. One of the particular interests is engineering bacteria as a live and targeted therapeutic delivery system. Herein, the bacterial biohybrid (E. coli-pE@PCN) is developed by genetically engineering Escherichia coli BL21 to overexpress catalase (E. coli-pE) and electrostatically adsorbing nano-sonosensitizers (PCN NPs) for enhanced and targeted sonodynamic therapy (SDT). Leveraging the ability to colonize and penetrate deep in tumors, engineered bacteria can not only sustainably express catalase to relieve tumor hypoxia, but also facilitate the enriched and expanded distribution of the carried sonosensitizer at the tumor site, so as to trigger effective SDT. More interestingly, it is found that E. coli-pE@PCN-based SDT can successfully inhibit the growth of subcutaneous and orthotopic colorectal tumors by inducing potent antitumor immune responses due to the released tumor-associated antigens and native immunogenicity of bacterial pathogen-associated molecular patterns. Furthermore, E. coli-pE@PCN-based SDT can not only prime a strong immune memory response to prevent tumor recurrence but also elicit a potent abscopal effect to inhibit tumor metastasis. Therefore, the programmable bacteria-based biohybrids developed here pave an avenue to prepare next-generation sonodynamic-immunotherapeutics to eliminate cancer and prevent its relapse and metastasis.

ACS Nano 2024 Q1IF=15.8

Cancer vaccines with the ability to elicit tumor-specific immune responses have attracted significant interest in cancer immunotherapy. A key challenge for effective cancer vaccines is the spatiotemporal codelivery of antigens and adjuvants. Herein, we synthesized a copolymer library containing nine poly(ethylene glycol) methyl ether methacrylate-co-butyl methacrylate-co-2-(azepan-1-yl)ethyl methacrylate (PEGMA-co-BMA-co-C7AMA) graft copolymers with designed proportions of different components to regulate their properties. Among these polymers, C-25, with a C7AMA:BMA ratio at 1.5:1 and PEG wt % of 25%, was screened as the most effective nanovaccine carrier with enhanced ability to induce mouse bone marrow-derived dendritic cell (BMDC) maturation. Additionally, RNA-sequencing (RNA-Seq) analysis revealed that C-25 could activate dendritic cells (DCs) through multisignaling pathways to trigger potent immune effects. Then, the screened C-25 was used to encapsulate the model peptide antigen, OVA257-280, to form nanovaccine C-25/OVA257-280. It was found that the C-25/OVA257-280 nanovaccine could effectively facilitate DC maturation and antigen cross-presentation without any other additional adjuvant and exhibited excellent prophylactic efficacy in the B16F10-OVA tumor model. Moreover, in combination with antiprogrammed cell death protein-ligand 1 (anti-PD-L1), the C-25/OVA257-280 nanovaccine could significantly delay the growth of pre-existing tumors. Therefore, this work developed a minimalist nanovaccine with a simple formulation and high efficiency in activating tumor-specific immune responses, showing great potential for further application in cancer immunotherapy.

The gut microbiota is closely associated with the progression of colorectal cancer (CRC) in which Fusobacterium nucleatum (F. nucleatum) was found to induce cancer resistance to chemotherapeutics. To relieve F. nucleatum induced drug resistance, herein, we found that short-chain fatty acid butyrate can inhibit the growth, enrichment and adhesion of F. nucleatum in colorectal cancer tissues by downregulating the expression of adhesion-associated outer membrane proteins, including RadD, FomA, and FadA, to reduce the colonization and invasion of F. nucleatum and relieve the chemoresistance induced by F. nucleatum. Leveraging the killing effect of butyrate on F. nucleatum, sodium butyrate (NaBu) was encapsulated in liposomes or prepared as NaBu tablets with Eudragit S100 coating and administered by intravenous injection or oral administration, respectively. Interestingly, both intravenous administration of NaBu liposomes and oral delivery of NaBu tablets could effectively inhibit the proliferation of F. nucleatum and significantly improve the therapeutic efficacy of oxaliplatin in mice with subcutaneous colorectal tumors, orthotopic colorectal tumors and even spontaneously formed colorectal tumors. Thus, our work provides a simple but effective formulation of NaBu to relieve F. nucleatum induced chemoresistance, exhibiting ideal clinical application prospects.

Despite the approval of immune checkpoint blockade (ICB) for colorectal cancer treatment, its objective response rate remains to be improved, especially for non-immunogenic tumors. Moreover, systemically administrated ICB antibodies is usually associated with immune-related adverse effects (irAEs). Herein, we report novel oral administration of anti-programmed cell death protein L1 (anti-PD-L1) complexes for immunotherapy against colorectal tumors. Antibodies could form nanocomplexes with fluorocarbon modified chitosan (FCS) to acquire greatly improved transmucosal penetration ability, owing to the ability of FCS to reduce mucus binding and temporary open tight junctions between epithelial cells. As evidenced in orthotopic colorectal tumors on mice, orally administrated FCS/anti-PD-L1 nanocomplexes exhibited greatly improved intestinal permeability and significant intertumoral penetration, and if combined with oxaliplatin (OXA) chemotherapy to induce an immunogenic tumor phenotype, could finally inhibit the growth of tumors and prolong the animal survival. Notably, compared to systematic injection of anti-PD-L1, oral administration of FCS/anti-PD-L1 achieved comparable therapeutic efficacy with five-fold dosage, and exhibited reduced tendency of systemic irAEs as exhibited by the decreased percentage of Th17 cells in lymph nodes. Our work here provides a simple but effective strategy for immunotherapy by oral administration of ICB antibodies, achieving strong antitumor immune responses without the concern of systemic irAEs.
