Gehua Jiecheng Decoction Inhibits Diethylnitrosamine-Induced Hepatocellular Carcinoma in Mice by Improving Tumor Immunosuppression Microenvironment. Front Pharmacol 2020; 11:809.

Abstract
Gehua Jiecheng Decoction (GHJCD), a famous traditional Chinese medicine, has been used in the prevention and treatment of precancerous lesion of liver cancer, but its active mechanism has not been reported. This study aimed to evaluate the therapeutic effect of GHJCD on diethylnitrosamine (DEN)-induced hepatocellular carcinoma (HCC) in mice and the mechanism of this effect. We found that GHJCD effectively inhibited the occurrence of liver cancer and reduced the tumor area. The ratio of regulatory cells (Tregs), tumor-associated macrophages (TAMs), and myeloid-derived suppressor cells (MDSCs) in HCC microenvironment was down-regulated, whereas that of CD8 T and effective CD8 T cells was up-regulated. In addition, the expression levels of inflammatory factors IL-6, IL-10, TNF-α, and CCL-2 in the liver were inhibited, whereas those of the angiogenesis related molecules CD31 and VEGF were decreased. Moreover, WNT1, β-catenin, NF-kB, p-MAPK, p-AKT, and p-SRC content in the liver decreased, whereas APC content increased. These results suggested that GHJCD exerted a good inhibitory effect on liver cancer induced by DEN and thus may have a multi-target effect; GHJCD not only antagonized the immunosuppressive effect of the microenvironment of liver cancer but also exerted strong anti-inflammatory and antiangiogenesis effects.

Abstract
Mounting evidence suggests that the gut microbiota contribute to colorectal cancer (CRC) tumorigenesis, in which the symbiotic Fusobacterium nucleatum (Fn) selectively increases immunosuppressive myeloid-derived suppressor cells (MDSCs) to hamper the host's anticancer immune response. Here, a specifically Fn-binding M13 phage was screened by phage display technology. Then, silver nanoparticles (AgNP) were assembled electrostatically on its surface capsid protein (M13@Ag) to achieve specific clearance of Fn and remodel the tumor-immune microenvironment. Both in vitro and in vivo studies showed that of M13@Ag treatment could scavenge Fn in gut and lead to reduction in MDSC amplification in the tumor site. In addition, antigen-presenting cells (APCs) were activated by M13 phages to further awaken the host immune system for CRC suppression. M13@Ag combined with immune checkpoint inhibitors (α-PD1) or chemotherapeutics (FOLFIRI) significantly prolonged overall mouse survival in the orthotopic CRC model.

Abstract
Due to the untargeted release of chemical drugs, the efficacy of chemotherapy is often compromised along with serious side effects on patients. Recently, the development of targeted delivery systems using nanomaterials as carriers has provided more alternatives for chemical drug transportation. In this study, we developed a novel targeted nanocomplex of GOQD-ICG-DOX@RBCM-FA NPs (GID@RF NPs). First, PEG modified graphene oxide quantum dots (GOQDs) were used to co-load the photosensitizer of indocyanine green (ICG) and DOX, to form GOQD-ICG-DOX NPs (GID NPs). Then, the red blood cell membrane (RBCM) was applied for GID NP camouflage to avoid immune clearance. Finally, folic acid was used to endow the targeting ability of GID@RF NPs. MTT assay showed that the survival rate of HeLa cells reduced by 71% after treatment with GID@RF NPs and laser irradiation. Meanwhile, membrane camouflage significantly prolonged the blood circulation time and enhanced the immune evading ability of GID NPs. Moreover, the drug accumulation at tumor sites was significantly improved through the strong interaction between FA and FA receptor highly expressed on the tumor cells. In vivo assay demonstrated the strongest tumor growth inhibition ability of the combinational chemo/photothermal therapy. H&E analysis indicated no significant abnormalities in the major organs of mice undergoing GID@RF NPs treatment. The level of blood and biochemical parameters remained stable as compared to the control. In summary, this combinational therapy system provides a safe, rapid and effective alternative for the treatment of cervical cancer in the future.

Abstract
Photothermal therapy (PTT) in the second near-infrared window (NIR-II, 1000-1350 nm) has presented great superiority in cancer treatment recently. However, it is generally limited to a few photothermal agents and most of them often suffer from intricate design and complicated synthesis. Herein, by subtly extracting nanoparticles from ancient ink (AINPs), a versatile AINP dispersion with definite ingredients, good biosafety, and excellent photothermal effect in the NIR-II window was obtained. In vivo trials demonstrated that the obtained AINP dispersion provides a promising alternative for tumor sentinel lymph node (SLN) mapping. Besides, under the guidance of photoacoustic imaging, the metastatic SLNs could be accurately eliminated by NIR-II laser irradiation. The preliminary biosafety of AINP dispersion has also been systematically confirmed. Therefore, we believe this work would provide a green and effective strategy for PTT of tumor in the NIR-II window.

Abstract
Palladium nanosheets (Pd NSs) have recently attracted increasing research interest in the biomedical field due to their excellent near-infrared absorption, photothermal conversion capability and biocompatibility. However, the application of Pd NSs in immunotherapy has not been reported. Here, Pd NSs were used as the carriers of immunoadjuvant CpG ODNs for not only efficient delivery of CpG but also for enhancing the immunotherapeutic effects of CpG by the Pd NS-based photothermal therapy (PTT). Pd NSs had no influence on the immune system, and the prepared Pd-CpG nanocomposites, especially Pd(5)-CpG(PS), could significantly increase the uptake of CpG by immune cells and enhance the immunostimulatory activity of CpG in vitro and in vivo. With the combination of Pd(5)-CpG(PS) mediated PTT and immunotherapy, highly efficient tumor inhibition was achieved and the survival rate of the tumor-bearing mice was greatly increased depending on Pd(5)-CpG(PS) with safe near-infrared (NIR) irradiation (808 nm laser, 0.15 W cm-2). Importantly, the combination therapy induced tumor cell death and released tumor-associated antigens, which could be effectively taken up and presented by antigen presenting cells with the assistance of CpG, leading to increased TNF-α and IL-6 production and enhanced cytotoxic T lymphocyte (CTL) activity. This work provides a new paradigm of utilizing photothermal nanomaterials for safe and highly efficient cancer photothermal combined immunotherapy.

Abstract
Natural killer (NK) cells can not only recognize and eliminate abnormal cells but also recruit and re-educate immune cells to protect the host. However, the functions of NK cells are often limited in the immunosuppressive tumor microenvironment (TME). Here, artificial NK cells (designated as aNK) with minor limitations of TME for specific tumor killing and renegade macrophage re-education are created. The red blood cell membrane (RBCM) cloaks perfluorohexane (PFC) and glucose oxidase (GOX) to construct the aNK. The aNK can directly kill tumor cells by exhausting glucose and generating hydrogen peroxide (H2 O2 ). The generated H2 O2 is also similar to cytokines and chemokines for recruiting immune cells and re-educating survived macrophages to attack tumor cells. In addition, the oxygen-carried PFC can strengthen the catalytic reaction of GOX and normalize the hypoxic TME. In vitro and in vivo experiments display that aNK with slight TME limitations exhibit efficient tumor inhibition and immune activation. The aNK will provide a new sight to treat tumor as the supplement of aggressive NK cells.
