Antigen Priming Induces Functional Reprogramming in iNKT Cells via Metabolic and Epigenetic Regulation: An Insight into iNKT Cell-Based Antitumor Immunotherapy. Cancer Immunol Res 2023; 11:1598-1610. [PMID: 37756568 DOI: 10.1158/2326-6066.cir-23-0448] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2023] [Revised: 08/04/2023] [Accepted: 09/20/2023] [Indexed: 09/29/2023]
Abstract
Dysfunction of intratumoral invariant natural killer T (iNKT) cells hinders their antitumor efficacy, but the underlying mechanisms and the relationship with endogenous antigen priming remain to be explored. Here, we report that antigen priming leads to metabolic reprogramming and epigenetic remodeling, which causes functional reprogramming in iNKT cells, characterized by limited cytokine responses upon restimulation but constitutive high cytotoxicity. Mechanistically, impaired oxidative phosphorylation (OXPHOS) in antigen-primed iNKT cells inhibited T-cell receptor signaling, as well as elevation of glycolysis, upon restimulation via reducing mTORC1 activation, and thus led to impaired cytokine production. However, the metabolic reprogramming in antigen-primed iNKT cells was uncoupled with their enhanced cytotoxicity; instead, epigenetic remodeling explained their high expression of granzymes. Notably, intratumoral iNKT cells shared similar metabolic reprogramming and functional reprogramming with antigen-primed iNKT cells due to endogenous antigen priming in tumors, and thus recovery of OXPHOS in intratumoral iNKT cells by ZLN005 successfully enhanced their antitumor responses. Our study deciphers the influences of antigen priming-induced metabolic reprogramming and epigenetic remodeling on functionality of intratumoral iNKT cells, and proposes a way to enhance efficacy of iNKT cell-based antitumor immunotherapy by targeting cellular metabolism.

Abstract
Renal inflammation and fibrosis are observed in underlying diseases associated with the pathological progression of chronic kidney disease (CKD). The inhibition of renal inflammation and fibrosis is one method to suppress the progression of CKD. Juzentaihoto (TJ-48), a Kampo medicine, effectively relieves chronic wasting diseases and fatigue and has been reported to decrease inflammation. In this study, we investigated whether TJ-48 has a renal protective effect and its underlying mechanism in mice with adenine-induced CKD. BALB/c mice were divided into four groups for examination: (1) control, (2) dietary restriction, (3) adenine, and (4) adenine + TJ-48. Biochemical and histological analyses, gene expression analysis, and complete blood counts were performed. TJ-48 treatment decreased tubular damage and fibrosis. TJ-48 also decreased creatinine levels exacerbated by adenine, suppressed the mRNA expression of tumor necrosis factor-α, chemokine ligand 2, transforming growth factor-β, and kidney injury molecule-1, and decreased the neutrophil/lymphocyte ratio increased by adenine. TJ-48 exerts a renoprotective effect possibly via the suppression of fibrosis and inflammation.

Abstract
Research on the bioactive components of herbal medicines have been conducted mainly on the secondary metabolites of herbal plants. Accordingly, limited information is available on primary metabolites (carbohydrates, amino acids, lipids, and nucleic acids) and their biological effects. Here, we focused on the heat-resistant RNA of a decoction of Glycyrrhizae Radix and showed its immunostimulatory effects. The RNA activated NF-κB/AP-1 and induced TNF-α production in murine macrophages. Further analysis revealed that the RNA was around 90 nucleotides long. RNA sequencing (RNA-Seq) by next generation sequencing (NGS) showed that approximately 30% of the NGS reads were mapped to the genome of Glycyrrhiza uralensis, which is plant material of Glycyrrhizae Radix. Further analysis of the other 70% of reads indicated that the RNA contained RNA sequences that could be mapped to various microorganisms. Together, these results propose nucleic acids as a new research field in the bioactive components of herbal medicines.

iNKT subsets differ in their developmental and functional requirements on Foxo1. Proc Natl Acad Sci U S A 2021; 118:2105950118.

Abstract
Invariant natural killer T (iNKT) cells play important roles in regulating immune responses. Based on cytokine profiling and key transcriptional factors, iNKT cells are classified into iNKT1, iNKT2, and iNKT17 subsets. However, whether the development and functions of these subsets are controlled by distinct mechanisms remains unclear. Here, we show that forkhead box protein O1 (Foxo1) promotes differentiation of iNKT1 and iNKT2 cells but not iNKT17 cells because of its distinct contributions to IL7R expression in these subsets. Nuclear Foxo1 is essential for Il7r expression in iNKT1 and iNKT2 cells at early stages of differentiation but is dispensable in iNKT17 cells. RORγt, instead of Foxo1, promotes IL7R expression in iNKT17 cells. Additionally, Foxo1 is required for the effector function of iNKT1 and iNKT2 cells but not iNKT17 cells. Cytoplasmic Foxo1 promotes activation of mTORC1 in iNKT1 and iNKT2 cells through inhibiting TSC1-TSC2 interaction, whereas it is dispensable for mTORC1 activation in iNKT17 cells. iNKT17 cells display distinct metabolic gene expression patterns from iNKT1 and iNKT2 cells that match their different functional requirements on Foxo1. Together, our results demonstrate that iNKT cell subsets differ in their developmental and functional requirements on Foxo1.

Abstract
INTRODUCTION The tumor microenvironment is involved in acquiring tumor malignancies of colorectal liver metastasis (CRLM). We have reported that TU-100 (Daikenchuto) suppresses hepatic stellate cell (HSC) activation in obstructive jaundice. In this study, we report new findings as the direct and indirect inhibitory effects of TU-100 on cancer cell growth through the suppression of HSC activation. MATERIALS AND METHODS The HSCs (LX2) were cultured in colon cancer cells (HCT116 and HT29)-conditioned medium (CM) with or without TU-100 treatment (90, 270, 900 μg/ml). Activated HSCs (aHSCs) were detected by α-SMA and IL-6 mRNA expressions and cytokine arrays of HSC's culture supernatants. Cancer cell growth was analyzed for proliferation and migration ability, compared with TU-100 treatment. To investigate the direct anti-tumor effect of TU-100, cancer cells were cultured in the presence of aHSC-CM and TU-100 (90, 270, 900) or aHSC-CM alone, and assessed autophagosomes, conversion to LC3-II protein, and Beclin-1 mRNA expression. RESULTS Colon cancer-CM significantly increased α-SMA and IL-6 mRNA expressions of aHSC. α-SMA and IL-6 mRNA expressions of aHSC, and IL-6 secretions from aHSCs were significantly decreased with TU-100 (270, 900) treatment, compared to colon cancer-CM alone. Compared with normal culture medium, aHSC-CM led to a significantly increased cell number and modified HSC-CM (TU-100; 270, 900) significantly suppressed cancer cell growth and migration. TU-100 (900) treatment induced autophagy and significantly promoted the autophagic cell death. CONCLUSIONS TU-100 inhibited colon cancer cell malignant potential by both suppressing HSC activation and inducing directly autophagy of cancer cells.

Abstract
OBJECTIVE Recurrent acute otitis media (AOM) in young children is rapidly increasing worldwide. Repeated antibiotic use leads to antibiotic-resistant pathogen development. Complementary and alternative medicine approaches have been suggested as a supplemental treatment option to conventional antimicrobial medicine. This randomized, parallel-group, open-label, non-herbal medicine controlled trial assessed the efficacy of a traditional Japanese herbal medicine, juzen-taiho-to (JTT) for AOM prevention in otitis-prone children. METHODS Children prone to recurrent AOM aged 6-48 months were recruited from 26 otolaryngology clinics in Japan and received conventional AOM treatment based on Japanese guidelines with or without 2 daily oral doses of JTT (0.10-0.25g/kg/day). The mean number of AOM episodes, coryza episodes, and duration of total antibiotic administration per month were compared during 3-month intervention. RESULTS At least one episode of AOM was diagnosed in 71% of JTT-group and 92% of control participants during follow-up. JTT administration reduced the frequency of AOM episodes by 57% compared with children who received conventional treatment alone (0.61±0.54 vs. 1.07±0.72 AOM instances/month; P=0.005) and also significantly decreased number of coryza episodes (P=0.015) and total antibiotic administration (P=0.024). CONCLUSIONS This is the first report of recurrent AOM prevention by herbal medication. JTT appears to effectively prevent recurrent AOM in children. Subsequent double-blind studies are needed to confirm the beneficial effects of JTT on recurrent AOM and upper respiratory tract infections.

Abstract
No traditional Japanese and Chinese herbal preparations have been shown to be effective antitumor agents, and a Japanese herbal therapy (Kampo medicine) for cancer that causes fewer adverse drug reactions than orthodox pharmaceuticals is desired. Our present study demonstrated that a Kampo preparation Daikenchuto (DKT) exerts an antitumor effect against various cancer cells. We also discovered an antitumor factor in Japanese Zanthoxylum peel, which is an ingredient of DKT. Breast, esophageal, gastric, and colon cancer cell lines were individually incubated with DKT for 1-72 h, followed by assessment of tumor growth inhibition by MTT assay. The cancer cells were also analyzed for apoptotic changes after DKT treatment. Nude mice were used to establish a model of gastric cancer tumor growth and peritoneal disseminated metastasis, in which the number of peritoneal disseminations was evaluated after oral administration of DKT for 4 weeks. In addition, the antitumor effects of the individual DKT ingredients (viz., ginseng, Japanese Zanthoxylum peel, and processed ginger) and other Kampo preparations were also analyzed. The antitumor effect of DKT was demonstrated in gastric, breast, esophageal, and colon cancer cells. DKT treatment induced apoptosis in these cells. Oral administration of DKT had a tendency to reduce the growth and significantly reduced the peritoneal dissemination of gastric cancer in the nude mouse model compared with control. DKT exhibited a higher antitumor effect than other Kampo preparations. Furthermore, Japanese Zanthoxylum peel, an ingredient of DKT, showed a particularly potent antitumor effect. Our study indicated that DKT is useful as a Kampo preparation for cancer therapy. We also showed that Japanese Zanthoxylum peel, an ingredient of DKT, contains an antitumor factor.

Abstract
Complementary and alternative medicine (CAM) including Japanese Kampo is known to have anticancer potential. An increasing number of cancer survivors are using CAM for disease prevention, immune system enhancement, and symptom control. Although there have been abundant previous clinical reports regarding CAM, scientific investigations aimed at acquiring quantifiable results in clinical trials, as well as basic research regarding CAM, have only recently been undertaken. Recent studies suggest that CAM enhancement of immune function is related to cytokines. This review provides a translational aspect of CAM, particularly Hozai in Kampo from both scientific and clinical points of view for further development of CAM for cancer treatment.

Abstract
Background Sipjeondaebo-tang, a traditional herbal medicine, has been reported to activate the immune response. Although, most research has focused on its anticancer activity. The purpose of this study was to determine whether Sipjeondaebo-tang exerts antioxidant activity against ethanol-induced gastric injury. Methods Gastric mucosal injury was induced by the oral administration of absolute ethanol at 5 mL/kg to rats after 18 h fast. Sipjeondaebo-tang water extract (SDTW; 200 mg/kg of body weight) was administered to rats 2 h before the oral administration of absolute ethanol. Gastric mucosal injury was evaluated by measuring the gastric injury, such as extent of lesions, malondialdehyde (MDA) concentration, glutathione (GSH) content and activities of antioxidant enzymes including catalase, glutathione peroxidase, glutathione S-transferase, glutathione reductase, and superoxide dismutase in stomach tissue. Results Oral administration of SDTW markedly decreased the damage by conditioning the gastric mucosa such as hemorrhage, hyperemia. Pretreatment with SDTW significantly reduced MDA concentration and significantly increased GSH content and the activities of antioxidant enzymes. In an acute toxicity study, no adverse effects of SDTW were observed at doses up to 5000 mg/kg/day. Conclusions SDTW may protect the gastric mucosa against ethanol-induced gastric mucosa injury. These results suggested that SDTW might also play an important role in the gastroprotection based on their antioxidant effect.

Abstract
We have performed a broad-ranging analysis of the adjuvant effect of a Kampo medicine, juzentaihoto (JTT), on influenza vaccination in a multicenter randomized controlled trial. In this study, the enhancing effect of JTT on antibody titer after influenza vaccination was studied for 28 weeks in elderly people who were in the high-risk group for influenza infection. In total, 91 subjects over 65 years old were recruited from four long-term-care facilities located in Chiba, Gunma, and Toyama prefectures in Japan. Participants were randomly assigned to the JTT and the control groups. Blood samples were taken at 4 weeks before vaccination, at the time of vaccination, and then at 4, 8, 12, and 24 weeks after vaccination. The hemagglutination inhibition (HI) titers against A/California/7/2009 (H1N1), A/Victoria/210/2009 (H3N2), and B/Brisbane/60/2008 were then manually measured. A significant increase in HI titer against H3N2 was observed at week 8 after vaccination in the JTT group compared with the control group (P = 0.0229), and the HI titer of the JTT group significantly increased from 4 to 24 weeks (P = 0.0468), compared with the control group. In conclusion, our results indicated that JTT increased and prolonged antibody production against A/Victoria/210/2009 (H3N2), in particular, after influenza vaccination.

Juzentaihoto Failed to Augment Antigen-Specific Immunity but Prevented Deterioration of Patients' Conditions in Advanced Pancreatic Cancer under Personalized Peptide Vaccine. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2013; 2013:981717. [PMID: 23840274 PMCID: PMC3691906 DOI: 10.1155/2013/981717] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/29/2013] [Revised: 05/28/2013] [Accepted: 05/29/2013] [Indexed: 11/18/2022]
Abstract
Juzentaihoto (JTT) is a well-known Japanese herbal medicine, which has been reported to modulate immune responses and enhance antitumor immunity in animal models. However, it is not clear whether JTT has similar effects on humans. In particular, there is little information on the effects of JTT in antigen-specific immunity in cancer patients. Here we conducted a randomized clinical study to investigate whether combined usage of JTT could affect antigen-specific immunity and clinical findings in advanced pancreatic cancer patients undergoing personalized peptide vaccination (PPV), in which HLA-matched vaccine antigens were selected based on the preexisting host immunity. Fifty-seven patients were randomly assigned to receive PPV with (n = 28) or without (n = 29) JTT. Unexpectedly, JTT did not significantly affect cellular or humoral immune responses specific to the vaccine antigens, which were determined by antigen-specific interferon-γ secretion in T cells and antigen-specific IgG titers in plasma, respectively. Nevertheless, JTT prevented deterioration of patients' conditions, such as anemia, lymphopenia, hypoalbuminemia, plasma IL-6 elevation, and reduction of performance status, which are frequently observed in advanced cancers. To our knowledge, this is the first clinical study that examined the immunological and clinical effects of JTT in cancer patients undergoing immunotherapy in humans.

Abstract
BACKGROUND The prognosis of pancreatic cancer is extremely poor regardless of various combination therapies. Immunoaugumentation against tumor cells was recently A focus. We reported that the population of Foxp3(+)CD25(+)CD4(+) regulatory T cells (Foxp3(+)Treg) was the new parameter for the estimation of host immunity and had correlation with tumor aggressiveness. Here we show the immunoaugumentation effects of Japanese Kampo medicine, Juzen-Taihoto/TJ-48, empirically considered as an immunoaugumentation drug, with investigation of Treg and other immunological parameters. PATIENTS AND METHOD Peripheral Foxp3(+) Treg populations, CD4/CD8 ratio, and CD57(+) cells (NK cells) populations in advanced pancreatic cancer patients (n = 30, stage VI A and B according to TNM classification) were estimated after TJ-48 administration for 14 days before the anti-cancer therapy. RESULTS Treg populations were significantly increased compared to healthy donors (Mann-Whitney U test, P < 0.001). Administration of Juzen-Taihoto/TJ-48 significantly decreased Treg populations (Mann-Whitney U test, P < 0.001) and increased the CD4/CD8 ratio (Mann-Whitney U test, P < 0.01), even though CD57(+) cell populations did not change significantly. CONCLUSIONS Juzen-Taihoto/TJ-48 increased regulatory activities in T cells through decreasing Foxp3(+) Treg populations in advanced pancreatic cancer patients. This effect can lead to immunoaugumentation for various combination therapies.

Abstract
PURPOSE Although Shi Quan Da Bu Tang (SQDBT) has been used to treat cancer patients clinically, very few studies evaluating the effectiveness of SQDBT using objective indicators have been published. The study objectives were to examine the effectiveness of SQDBT for alleviating hematotoxicity, as indicated by white blood cell (WBC) counts and hemoglobin (Hb) levels, among patients with breast carcinoma receiving chemotherapy. METHODS The authors identified patients with breast carcinoma who received chemotherapy in a teaching hospital in Taipei in 2008 through a chart review process. Only patients with initial WBC counts of <4000/µL were included. The case group was composed of 47 chemotherapy courses treated with SQDBT, whereas the comparison group included 257 courses without SQDBT. The complete blood count test was done before start of a chemotherapy course and 1 week after chemotherapeutic drugs were given. RESULTS Age, cancer stage, cancer status, use of granulocyte colony-stimulating factor, and chemotherapy drugs were controlled in the model. Patients who took SQDBT had significantly increased WBC counts, especially neutrophils, and Hb after chemotherapy (adjusted β = 1202.51, 95% confidence interval [CI] 440.45-1964.57 for WBC; β = 834.83, 95% CI = 197.35-1472.31 for neutrophils; β = 0.34, 95% CI = 0.05-0.63 for Hb). There were no significant differences in tumor markers CEA and CA153 between patients given SQDBT or not after chemotherapy. CONCLUSION SQDBT is effective in alleviating hematotoxicity among patients with breast carcinoma receiving chemotherapy, without affecting the presentation of tumor markers in the short term. More study is needed to determine long-term outcomes such as recurrence and survival.

Abstract
Type 1 diabetes mellitus (T1DM) is mainly caused by CD8(+) cytotoxic T cell infiltration into islets. Recently, the role of regulatory T cells (Tregs) in the prevention of the onset of T1DM was reported. We reported that TJ-48, a common Japanese herbal medicine, decreased Treg population in cancer patients, thus we investigated whether TJ-48 had an influence on T1DM onset using NOD mice. In the TJ-48 group, TJ-48 (2.0g/kg/day) was administered in the drinking water for NOD mice from three weeks of age to 20 weeks of age. Their body weight and fast blood glucose (FBG) were measured every week. Histology (Hematoxylin-Eosin staining) was investigated every month. Lymphocyte profiles were investigated every month with FACS. The results were compared to the age-matched NOD mice control group. FBG of the control group mice showed diabetic status of 66.7% at 18 weeks of age. On the other hand, the TJ-48 group mice showed diabetic status of 16.7% at 18 weeks of age (p = 1.905E-06). There were no significant differences in general conditions or body weight between the two groups. Lymphocyte infiltrations into islets were dramatically suppressed in the TJ-48 group. The effect of TJ-48 on decreasing Tregs was less apparent in the NOD mice model. TJ-48 inhibited lymphocyte infiltrations into islets, which led to preventing the onset of T1DM in NOD mice.

Subchronic toxicity of Sipjeondaebo-tang (SDT) in Sprague-Dawley rats. Regul Toxicol Pharmacol 2010; 59:375-84. [PMID: 20937344 DOI: 10.1016/j.yrtph.2010.09.018] [Citation(s) in RCA: 10] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2010] [Revised: 09/30/2010] [Accepted: 09/30/2010] [Indexed: 11/21/2022]
Abstract
Sipjeondaebo-tang (SDT, Juzen-taiho-to in Japanese), a traditional Korean herbal medicine, is used as a supplemental treatment for the adverse effects of chemotherapy, radiation therapy, and surgical treatment. However, limited information is available about the long-term safety of SDT. Therefore, we evaluated the potential adverse effects of SDT in Sprague-Dawley rats over a period of 13-weeks. The SDT was administered once daily by gavage to male and female rats at dose levels of 0, 250, 500, 1000 and 2000 mg/kg/day for 13 weeks. The SDT treatment did not result in any toxicologically significant changes in mortality, clinical signs, body weights, food and water consumption, ophthalmoscopy, urinalysis, hematology, serum biochemistry, gross findings, organ weights, histopathology, estrus cycle, serum testosterone levels and sperm analysis. We concluded that the 13-week repeated oral administration of SDT did not cause any adverse effects in rats at dose levels of ≤ 2000 mg/kg/day. Under these experimental conditions, the no-observed-adverse-effect level (NOAEL) was more than 2000 mg/kg/day for both genders. Here, we demonstrated the safety of a 13-week repeated oral dose and considered that it is a safe herbal medicine for human consumption.
