Abstract
Metal ions play an essential role in regulating the functions of immune cells by transmitting intracellular and extracellular signals in tumor microenvironment (TME). Among these immune cells, we focused on the impact of metal ions on T cells because they can recognize and kill cancer cells and play an important role in immune-based cancer treatment. Metal ions are often used in nanomedicines for tumor immunotherapy. In this review, we discuss seven metal ions related to anti-tumor immunity, elucidate their roles in immunotherapy, and provide novel insights into tumor immunotherapy and clinical applications.

Abstract
The slightest change in the extra/intracellular concentration of metal ions results in amplified effects by signaling cascades that regulate both cell fate within the tumor microenvironment and immune status, which influences the network of antitumor immunity through various pathways. Based on the fact that metal ions influence the fate of cancer cells and participate in both innate and adaptive immunity, they are widely applied in antitumor therapy as immune modulators. Moreover, nanomedicine possesses the advantage of precise delivery and responsive release, which can perfectly remedy the drawbacks of metal ions, such as low target selectivity and systematic toxicity, thus providing an ideal platform for metal ion application in cancer treatment. Emerging evidence has shown that immunotherapy applied with nanometallic materials may significantly enhance therapeutic efficacy. Here, we focus on the physiopathology of metal ions in tumorigenesis and discuss several breakthroughs regarding the use of nanometallic materials in antitumor immunotherapeutics. These findings demonstrate the prominence of metal ion-based nanomedicine in cancer therapy and prophylaxis, providing many new ideas for basic immunity research and clinical application. Consequently, we provide innovative insights into the comprehensive understanding of the application of metal ions combined with nanomedicine in cancer immunotherapy in the past few years.

Abstract
The capacity of T cells to identify and kill cancer cells has become a central pillar of immune-based cancer therapies. However, T cells are characterized by a dysfunctional state in most tumours. A major obstacle for proper T-cell function is the metabolic constraints posed by the tumour microenvironment (TME). In the TME, T cells compete with cancer cells for macronutrients (sugar, proteins, and lipid) and micronutrients (vitamins and minerals/ions). While the role of macronutrients in T-cell activation and function is well characterized, the contribution of micronutrients and especially ions in anti-tumour T-cell activities is still under investigation. Notably, ions are important for most of the signalling pathways regulating T-cell anti-tumour function. In this review, we discuss the role of six biologically relevant ions in T-cell function and in anti-tumour immunity, elucidating potential strategies to adopt to improve immunotherapy via modulation of ion metabolism.

Abstract
Colorectal cancer (CRC), a common malignant disease, has the second highest mortality rate among all cancer types. Due to the diversity and heterogeneity of CRC, few effective treatment strategies have been developed in recent years, except for surgical resection. As immunotherapy has become a revolutionary treatment after surgery, along with chemoradiotherapy and targeted therapy, numerous basic research studies and clinical trials have been conducted on CRC. Therefore, immune checkpoint inhibitor (ICI) therapy has become the main anti-CRC immunotherapy method used at present. With the rapid development of biotechnology and cell research, an increasing number of monotherapy or combination therapy strategies using ICIs for CRC have been designed in recent years. Methods to classify and review ICI strategies for different types of CRC to better guide treatment are continuously investigated. However, the identification of why the ICIs would be more effective in targeting particular subtypes of CRC such as high microsatellite instability (MSI-H) is more important because of the different immune backgrounds in patients. This review intends to classify different subtypes of CRC and summarizes the basic and clinical studies on ICIs for each subtype of CRC currently available. In addition, we also attempt to briefly discuss the progress in immunotherapy methods other than ICI therapy, such as chemoimmunotherapy strategy, chimeric antigen receptor-modified T (CAR-T) cells, or immunotherapy based on oncolytic viruses. Finally, we provide a perspective on the development of immunotherapy in the treatment of CRC and attempt to propose a new systematic classification of CRC based on immunological strategies, which may improve guidance for the selection of immunotherapy strategies for different subtypes of CRC in the future.

Abstract
Manganese (Mn2+) has been reported to activate macrophages and NK cells, and to induce the production of type-I interferons (IFNs) by activating the cGAS-STING pathway. Few studies have been conducted on its adjuvanticity to microbial vaccines, and on the involvement of the interferon regulatory factor (IRF) 5 signaling pathway in the adjuvanticity. In this study, we demonstrated that Mn2+ could facilitate various microbial vaccines to induce enhanced antibody responses, and facilitate the influenza virus vaccine to induce protective immunity against the influenza virus challenge. When formulated in vaccines, Mn2+ could activate murine CD4+ T cells, CD8+ T cells, B cells and DCs, and induce the expression and phosphorylation of TANK-binding kinase 1 (TBK1) and IRF5 in the splenocytes of the immunized mice, resulting in the increased expression of type-I IFNs, TNF-α, B cell-activating factor of the TNF family (BAFF) and B lymphocyte-induced maturation protein-1 (Blimp-1). The induced TBK1 could recruit and bind the IRF5. Furthermore, the Mn2+ induced expression of IRF5 and Blimp-1 was prohibited by a IRF5 interfering oligonucleotide. The data suggest the Mn2+ could be used as a novel type of adjuvants for microbial vaccines, and the activation of IRF5 signaling pathway might involve in the adjuvanticity.

Manganese is critical for antitumor immune responses via cGAS-STING and improves the efficacy of clinical immunotherapy. Cell Res 2020; 30:966-979.

Abstract
CD8+ T cell-mediated cancer clearance is often suppressed by the interaction between inhibitory molecules like PD-1 and PD-L1, an interaction acts like brakes to prevent T cell overreaction under normal conditions but is exploited by tumor cells to escape the immune surveillance. Immune checkpoint inhibitors have revolutionized cancer therapeutics by removing such brakes. Unfortunately, only a minority of cancer patients respond to immunotherapies presumably due to inadequate immunity. Antitumor immunity depends on the activation of the cGAS-STING pathway, as STING-deficient mice fail to stimulate tumor-infiltrating dendritic cells (DCs) to activate CD8+ T cells. STING agonists also enhance natural killer (NK) cells to mediate the clearance of CD8+ T cell-resistant tumors. Therefore STING agonists have been intensively sought after. We previously discovered that manganese (Mn) is indispensable for the host defense against cytosolic dsDNA by activating cGAS-STING. Here we report that Mn is also essential in innate immune sensing of tumors and enhances adaptive immune responses against tumors. Mn-insufficient mice had significantly enhanced tumor growth and metastasis, with greatly reduced tumor-infiltrating CD8+ T cells. Mechanically, Mn2+ promoted DC and macrophage maturation and tumor-specific antigen presentation, augmented CD8+ T cell differentiation, activation and NK cell activation, and increased memory CD8+ T cells. Combining Mn2+ with immune checkpoint inhibition synergistically boosted antitumor efficacies and reduced the anti-PD-1 antibody dosage required in mice. Importantly, a completed phase 1 clinical trial with the combined regimen of Mn2+ and anti-PD-1 antibody showed promising efficacy, exhibiting type I IFN induction, manageable safety and revived responses to immunotherapy in most patients with advanced metastatic solid tumors. We propose that this combination strategy warrants further clinical translation.

Biol Trace Elem Res 2018; 181:347-360. [PMID: 28555440 DOI: 10.1007/s12011-017-1060-9] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/14/2017] [Accepted: 05/22/2017] [Indexed: 12/17/2022]
Abstract
Manganese (Mn) is an essential nutrient for both host and pathogen. Recent studies have demonstrated the nutritional immunity of Mn against Salmonella infection in mammals. To investigate the effect of high dietary Mn on immune responses of broilers following Salmonella challenge, 144 1-day-old male broilers were fed a basal diet (containing 20.04 mg Mn/kg) plus an additional 40 (the control group) or 400 mg Mn/kg (the H-Mn group) for 7 days. The 72 broilers in each group were then orally inoculated with 5 × 107 CFUs of Salmonella typhimurium (ATCC#14028) or phosphate-buffered saline. Peripheral blood, spleens, cecal tonsils, and bursa of Fabricius were collected from Salmonella-inoculated and Salmonella-noninoculated broilers (n = 6) at 2 days post inoculation (2 DPI) and 7 days post inoculation (7 DPI). Peripheral blood lymphocyte subpopulations were determined by flow cytometry. The messenger RNA (mRNA) abundance of genes was determined by quantitative real-time polymerase chain reaction. Salmonella counts were higher (P < 0.05) in the H-Mn group than that in the control group at 2 DPI in the cecal contents of Salmonella-inoculated broilers. High dietary Mn increased CD3+CD4+ and CD3+CD8+ percentages in the peripheral blood of Salmonella-inoculated broilers at 2 DPI. Salmonella inoculation increased interleukin (IL)-6 mRNA expression in spleens and bursa of Fabricius at 2 DPI and increased IL-1β and IL-6 mRNA expression in cecal tonsils at 7 DPI in the H-Mn group. These changes were not observed in the control group. High dietary Mn increased interferon-γ (IFN-γ) in spleens and decreased IFN-γ and IL-12 mRNA expression in cecal tonsils of Salmonella-inoculated broilers at 2 DPI. High dietary Mn decreased IL-17 mRNA expression in the bursa of Fabricius at 7 DPI, but increased this expression in cecal tonsils at 2 and 7 DPI in Salmonella-inoculated broilers. These results suggested that dietary Mn level affected T helper (Th) 1-cytokine reaction in spleens and cecal tonsils, and Th17-mediated immunity in cecal tonsils and the bursa of Fabricius of broilers when challenged with Salmonella.

Abstract
Resistance to infection with the nonlethal rodent malaria parasite Plasmodium yoelii 17XNL (Py 17XNL) is mediated by humoral, T-cell and accessory cell activity. The purpose this study was to profile host resistance to infection with this organism in mice exposed to 2'-deoxycoformycin (2dCF), a potent adenosine deaminase (ADA) inhibitor. Inhibition of ADA activity by 2dFC results in defective T-cell function and either suppression or augmentation of the humoral response, depending on whether 2dCF exposure precedes (suppression) or follows (augmentation) immunization. In this study, mice injected with 2dCF during the first five days of infection cleared the infection at the same time as controls, but had lower peak parasitemia than controls. Mice infected with the lethal variant of P. yoelii were more susceptible to infection when injected with 2dCF after infection, suggesting that 2dCF injection did not directly affect the parasite. Rather, suppression of parasitemia in 2dCF-treated mice may have been mediated by augmented humoral immunity, since 2dCF injection increases antibody responses when 2dCF injection follows antigen (in this case, parasite) injection. Conversely, in mice given 2dCF prior to infection, parasitemia peaked 2 days later and was eliminated more gradually than in control mice. Exposure to 2dCF did not deplete reticulocytes and thus temporarily limit parasitemia. Similarly, enrichment of NK cells or augmentation of macrophage phagocytic activity prior to infection were not sufficient to alter the pattern of infection. In contrast, the pattern of infection in mice treated with tilorone (a macrophage activator which also causes suppressed T-cell function) prior to infection was similar to that observed in 2dCF-exposed animals. These results indicate that 2dCF, given before or after infection, alters the host response to infection with Py17XNL. It appears that a combination of increased macrophage activity and altered T-cell activity contributed to the delay in peak parasitemia and clearance of infection in mice exposed to 2dCF before infection with Py17XNL.

Abstract
Recent evidence has implicated enkephalins as immunomodulators. Several studies have reported the regulation of tumor growth by methionine enkephalin (ME). However, there has been little effort to relate the immunological significance of enkephalins to the development of anticancer drugs. The present study had three aims: first, to compare the antitumor activity of the synthetic peptide, D-[Ala2]methionine enkephalinamide (MEA), with endogenous enkephalins on PYB6 fibrosarcoma tumor growth; second, to determine whether tumor growth inhibition was mediated by an opiate receptor; and third, to investigate the effects of MEA on selected immune responses. Female B6C3F1 mice were injected i.p. daily for 7 days with 50-4000 micrograms/kg of ME, MEA, leucine enkephalin (LE) or D-[Ala2]leucine enkephalinamide (LEA), beginning 1 day after PYB6 inoculation. ME and MEA, but not LE or LEA, decreased the PYB6 growth rate. The dose of 50 micrograms/kg MEA exerted the maximum inhibition of tumor growth (nearly 72% on day 15 post tumor transplantation). MEA was not directly toxic to PYB6 tumor cells, as evaluated by the measurement of DNA synthesis and cellular ATP levels of PYB6 cells exposed to MEA in vitro. No [3H]-etorphine specific bindings were detected on the cell membrane or sonicates of splenic lymphocytes or PYB6 cells. Therefore, the antitumor activity by MEA is likely mediated by an indirect mechanism. Immunological studies indicated that MEA selectively enhanced the lymphoproliferative response to the T-cell mitogen, concanavalin A, but not to the B-cell mitogen, lipopolysaccharide.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The effect that MnCl2 has on murine splenic natural killer (NK) cell activity was investigated in infant (10 days old), pre-weanling (18 days old) and weanling (24 days old) C57BL/6J mice. A single intraperitoneal injection of 10, 20 or 40 micrograms MnCl2/g body weight caused a significant enhancement in NK activity, as determined by the in vitro 51Cr release assay. Comparable enhancement of NK activity was observed for age-matched mice injected intraperitoneally with polyinosinic polycytidylic acid (Poly I:C). Both MnCl2 and Poly I:C caused elevations in serum interferon levels. Time-course studies revealed that interferon levels returned to normal within 48 hours following injection with either MnCl2 or Poly I:C; however enhanced NK activity persisted for up to 48 hours in Poly I:C-injected mice and 72 hours in MnCl2-injected mice. The administration of rabbit anti-asialo GMl to MnCl2-injected mice completely abrogated the enhanced NK activity. In addition, the injection of rabbit anti-mouse interferon alpha, beta but not gamma completely abrogated the enhanced NK activity. In addition, the injection of rabbit anti-mouse interferon alpha, beta but not gamma completely abrogated the enhancement of NK activity by MnCl2 and to a lesser extent the enhancement of NK activity by Poly I:C. These results indicate that despite low levels of NK activity in pre-weanling mice, MnCl2 is capable of enhancing this activity by 8-9 fold. Furthermore, Mn-enhanced NK activity in these young mice appears to be mediated by the production of interferon alpha, beta.

Abstract
Immunological effects of manganese chloride (MnCl2) were determined in male CD-1 mice injected (ip) daily with MnCl2 (0, 1, 3, or 10 mg/kg) for 4 wk. Liver and spleen weights increased in the 10-mg/kg MnCl2 treatment group. The weights of thymus, kidney, and adrenal glands were not affected by MnCl2 treatment. No significant differences in peripheral erythrocyte or leukocyte counts were observed; however, packed cell volumes decreased in the medium- and high-dose groups. Manganese treatment significantly increased the uptake of [3H]thymidine (3H-TdR) by cultured splenic cells. The lymphoproliferative responses to phytohemagglutinin (PHA) and concanavalin A (Con A) increased at all levels of MnCl2 exposure. No differences in the responses to lipopolysaccharide (LPS) were observed. Mixed lymphocyte responses increased significantly with exposure to 10 mg MnCl2/kg. Another immunological alteration induced by MnCl2 was a dose-dependent immunosuppressive effect on the development of antibody-forming cells. The production of anti-sheep red blood cell antibody (alpha-SRBC) nearly ceased following exposure to 10 mg MnCl2/kg. This effect was apparently reversible, as the number of plaque-forming cells in the 10-mg/kg treatment group increased after MnCl2 treatment had been halted for 2 wk. The alpha-SRBC titer also decreased significantly in the 10-mg/kg treatment group, corresponding to the reduction of antibody producing cells. MnCl2 treatment was immunomodulatory to the reduction of antibody producing cells. MnCl2 treatment was immunomodulatory in male CD-1 mice, as indicated by the increase in mitogen and mixed lymphocyte responses and decrease in antibody production.

Abstract
The effects that divalent metals have on nickel-induced suppression of natural killer (NK) cell activity were studied in mice. Male CBA/J mice were given a single intramuscular injection of metal salt on a body weight basis. The metal doses used were the following: nickel chloride, 4.5-36 micrograms/g; manganese chloride, 20-80 micrograms/g. Twenty-four hours after metal injection, splenic NK cell activity was assessed using a 51Cr-release assay. Ni significantly (p less than 0.01) suppressed NK activity, while Mn significantly (p less than 0.01) enhanced NK activity. No alteration in NK activity was observed in mice injected with Mg, Ca, or Zn. Since these divalent metals have been shown to have antagonistic effects on Ni-induced carcinogenicity and toxicity, they were used in combination with Ni to determine if such antagonisms exist for NK cell activity. The injection of Ni and Mn in combination at a single site resulted in the enhancement of NK activity, although this enhancement was at a level below that observed following the injection of Mn alone. Injection of Mg, Zn, or Ca in combination with Ni did not affect NK activity compared to saline controls. In contrast, the injection of Ni in one thigh followed immediately by Mn, Mg, Ca, or Zn into the other thigh resulted in significant suppression of NK activity for all metals compared with saline controls. An interesting finding was that the injection of Ni followed immediately by Mn into the opposite thigh resulted in even greater reductions in NK activity than Ni alone. Suppression of NK activity by Ni and Mn injected at separate sites was not seen when Mn injection preceded Ni injection by 1 h. These data indicate that both the divalent metal and the timing of its injection relative to Ni injection are critical for altering Ni-induced suppression of NK cell activity.

Abstract
The in vitro cultivation of murine spleen cells with MnCl2 resulted in the enhancement of natural killer (NK) cell activity as measured in a 4-h 51Cr-release assay. Optimal enhancement of NK activity was observed at concentrations of 10-20 micrograms MnCl2/culture (72-144 microM Mn2+). Enhancement of NK activity by MnCl2 was not associated with any changes in the number or viability of cells following culture. The addition of antiasialo GM1 antibody and complement to spleen cell cultures completely abrogated the enhancement of NK activity by MnCl2. The enhancement of NK activity by MnCl2 in vitro was accompanied by interferon induction. The addition of rabbit antimouse interferon to spleen cells cultured with MnCl2 reduced NK activity. NK activity in cultures treated with MnCl2 was also reduced upon removal of plastic adherent cells. However, restoration of enhanced NK activity by addition of adherent cells to nonadherent cells in the presence of MnCl2 was not observed. Similar effects of NK activity were observed with polyinosinic-polycytidylic acid (Poly I X C), a known interferon inducer and NK enhancer. The results demonstrate that murine splenic NK activity is enhanced in vitro by MnCl2 and that this enhancement may be mediated by interferon induction. The results also suggest that in vitro enhancement of NK activity by MnCl2, as with Poly I X C, may require participation of an adherent cell population for NK augmentation.

Abstract
A single intramuscular injection of MnC12 in mice caused an increase in macrophage functional activity. Spleen cell antibody-dependent cell-mediated cytotoxicity against both chicken erythrocytes and P815 tumor cell targets was enhanced 24 h following a single injection of MnC12. Enhanced antibody-dependent cell-mediated cytotoxicity activity following MnC12 treatment was not associated with a change in spleen cellularities compared with saline-injected mice. Resident peritoneal macrophages from mice injected intramuscularly with MnC12 displayed enhanced phagocytic activity for chicken erythrocytes in the presence or absence of opsonizing antibody. Enhanced cytolytic activity against P815 mastocytoma target cells and enhanced cytostatic activity against MBL-2 lymphoma target cells was also observed for nonelicited resident peritoneal macrophages from mice injected intramuscularly with MnC12. There were no differences in the cellularity or relative number of adherent cells obtained from the peritoneal cavity of saline or MnC12-injected mice. These enhanced macrophage functions were associated with the induction of increased interferon levels in mice injected with MnC12.
