Application of immune checkpoint targets in the anti-tumor novel drugs and traditional Chinese medicine development. Acta Pharm Sin B 2021; 11:2957-2972. [PMID: 34729298 PMCID: PMC8546663 DOI: 10.1016/j.apsb.2021.03.004] [Citation(s) in RCA: 38] [Impact Index Per Article: 12.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2020] [Revised: 12/31/2020] [Accepted: 01/07/2021] [Indexed: 12/17/2022] Open
Abstract
Immune checkpoints are the crucial regulators of immune system and play essential roles in maintaining self-tolerance, preventing autoimmune responses, and minimizing tissue damage by regulating the duration and intensity of the immune response. Furthermore, immune checkpoints are usually overexpressed in cancer cells or noninvasive cells in tumor tissues and are capable of suppressing the antitumor response. Based on substantial physiological analyses as well as preclinical and clinical studies, checkpoint molecules have been evaluated as potential therapeutic targets for the treatment of multiple types of cancers. In the last few years, extensive evidence has supported the immunoregulatory effects of traditional Chinese medicines (TCMs). The main advantage of TCMs and natural medicine is that they usually contain multiple active components, which can act on multiple targets at the same time, resulting in additive or synergistic effects. The strong immune regulation function of traditional Chinese medicine on immune checkpoints has also been of great interest. For example, Astragalus membranaceus polysaccharides can induce anti-PD-1 antibody responses in animals, and these antibodies can overcome the exhaustion of immune cells under tumor immune evasion. Furthermore, many other TCM molecules could also be novel and effective drug candidates for the treatment of cancers. Therefore, it is essential to assess the application of immune checkpoints in the development of new drugs and TCMs. In this review, we focus on research progress in the field of immune checkpoints based on three topics: (1) immune checkpoint targets and pathways, (2) development of novel immune checkpoint-based drugs, and (3) application of immune checkpoints in the development of TCMs.

Abstract
The human immune system represents a dynamic multiscale system with high complexity in biology. Humoral immunity, as the main branch of adaptive immunity, is characterized by differentiated stages of the B lymphocytes, producing the final product of antibodies that has a diversity of the tuning mechanisms within genetic and epigenetic levels in confrontation with environmental exposures. Disorders because of disturbed humoral immunity are linked with dysregulation of feedback-regulated signaling and the dynamic of immune components that determine the overall response. Food products, mainly herbal components have a significant role in tailoring the immune system micro-ecosystem which can diversify the adaptive nature of humoral immunity. Herein, we review the current evidence-based approaches for the impact of medicinal herbs on humoral immunity signaling and antibody production with a focus on immunotherapeutic applications.

Abstract
BACKGROUND Herbal medicine plays an important role in health, particularly in remote parts of developing areas with few health facilities. According to WHO estimates, about three-quarters of the world's population currently use herbs or traditional medicines to treat various ailments, including liver diseases. Several studies have found that the use of medicinal plants was effective in the treatment of infectious and non-infectious diseases. Hepatitis and liver cirrhosis associated with many clinical manifestations can be treated with allopathic medicines, but reports of a number of side effects including immunosuppression, bone marrow suppression, and renal complications have motivated researchers to explore more natural herbal medicines with low or no side effects and with high efficacy in treating hepatic diseases. METHODS Databases including PubMed, Medline, and Google Scholar were searched for findings on the hepatoprotective effects of plants. RESULTS Various medicinal plants are used for the treatment of liver disorders. The range of alternative therapies is huge, and they are used worldwide, either as part of primary health care or in combination with conventional medicine. Hepatoprotective plants contain a variety of chemical constituents including flavonoids, alkaloids, glycosides, carotenoids, coumarins, phenols, essential oil, organic acids, monoterpenes, xanthenes, lignans, and lipids. CONCLUSION This review shows that numerous plants are found to contain hepatoprotective compounds. However, further studies are needed to determine their association with existing regimes of antiviral medicines and to develop evidence-based alternative medicine to cure different kinds of liver disease in humans.

Abstract
Herbal medicines are currently employed for the treatment of several types of diseases, and also employed for the improvement of Quality of Life (QOL) of patients over the world, in particular, in Asian countries. In Japan, a Japanese herbal medicine namely kampo medicine has been prescribed for the improvement of QOL of patients. Ninjinyoeito (NYT), composed of 12 herbal plants, is one of kampo medicines and used for helping recovery of diseases and improving several symptoms that suffer patients such as anemia, anorexia and fatigue. Recent scientific research approaches to kampo medicines with cells and animal models enable to prove that NYT has multiple functions for improvement of symptoms. Also, clinical studies using NYT support such actions to be widely used for the improvement of symptoms that reduce the QOL of patients.

Abstract
(Purpose) Targeted therapy has been standard therapeutic approach for advanced renal cell carcinoma (RCC). General fatigue is frequently observed in patients who receive targeted therapies for advanced RCC. General fatigue makes it difficult to continue a standard schedule of treatment in many cases. In this preliminary report, we explored the effect of Koujin powder (red ginseng powder) with Ninjin-youeito for general fatigue induced by targeted therapies for advanced RCC. (Material and method) The patients who complained of general fatigue during the treatment of Tyrosine Kinase Inhibitors (TKIs) as targeted therapies for advanced RCC were included in this retrospective analysis. Thirty patients with advanced RCC were enrolled from January 2016 to December 2016 at Chiba University Hospital. Twelve patients were given 3 g of Koujin powder with 9 g of Ninjin-youeito orally for two to four weeks (ginseng combination group). Eighteen patients who were not orally administered were compared as a control group (ginseng non-combination group). General fatigue was assessed with the Cancer Fatigue Scale (CFS), which divides quality of fatigue into three subgroups by using a "physical subscale", an "affective subscale", and a "cognitive subscale". We compared CFS scores at baseline and 2-8 weeks after administration. (Results) There was no statistical difference in the clinical variables between the two groups. The total CFS score was significantly decreased after treatment in the ginseng combination group (average score, 21.8 points at baseline vs 18.5 points after treatment; p=0.041). On subgroup analyses, the physical subscale score was significantly reduced after treatment in the ginseng combination group (average score, 9.7 points at baseline vs 7 points after treatment; p=0.0042). In the ginseng non-combination group, the total CFS score was significantly increased during the course (average score, 16.2 points at baseline vs 20.6 points during the course; p=0.047). On subgroup analyses, the physical subscale score was significantly increased during the course (average score, 4.4 points at baseline vs 7.3 points during the course; p=0.0042). (Conclusions) Koujin powder with Ninjin-youeito can be a therapeutic approach for general fatigue induced by targeted therapies. The precise management for general fatigue can keep patients on therapy, consequently provides a survival benefit.

Abstract
BACKGROUND Combretum hereroense and Canthium mundianum are two plants commonly used by traditional healers in the Northern region of Limpopo, South Africa for the treatment of diarrhea and inflammation. In the present study, the effects of their water extracts on the production and expression of interleukin-4 by peripheral blood mononuclear cells (PBMC'S) from HIV positive and negative individuals was evaluated. MATERIALS AND METHODS Blood samples were collected from both HIV positive and HIV negative volunteers and were used for the purification of Peripheral blood mononuclear cells (PBMC). The PBMCs were cultured together with the water extracts after activation with phytohemagglutinin (PHA) for three days. Solid-phase sandwich ELISA (MABTECH) kit was used to detect IL-4 on un-stimulated and stimulated PBMC'S with phytohemaglutinin (PHA) and plant extracts, followed by the isolation of RNA using RNAesy Qiagen mini kit from the cells. Reverse transcriptase real time PCR was used to evaluate IL-4 gene expression by the cells. RESULTS Combretum hereroense showed higher production of IL-4 at three different concentrations and a significant expression of mRNA with 4-fold amplification increase at 300μg/ml and 2-fold amplification increase at 20μg/ml. Canthium mundianum also showed increased production of IL-4 at 300μg/ml, but inhibited its production at 20μg/ml. Both extracts showed no expression at 50μg/ml. The response of the PBMCs from HIV negative individuals was more pronounced than that of HIV positive individuals who mostly increased production of IL4 at smaller concentrations unlike their HIV negative counterparts. Although in vitro studies do not necessarily predict in vivo outcomes, the plant extracts modulated the immune system by enhancing the production and expression of IL-4 in both HIV- and HIV+ individuals at different concentrations. CONCLUSIONS For the first time we have shown that the immunomodulatory effect of medicinal plants may depend on the clinical status of the individual. The present study revealed that the effect of the water extracts from the two plants on IL-4 expression and production is dependent on the microbiological state of the individual and is dose dependent. Further studies are needed to identify the active components in the extracts and also characterize the patients further for a better understanding of the mechanisms of action of these extracts.

Abstract
Panax ginseng Meyer has been widely used as a tonic in traditional Korean, Chinese, and Japanese herbal medicines and in Western herbal preparations for thousands of years. In the past, ginseng was very rare and was considered to have mysterious powers. Today, the efficacy of drugs must be tested through well-designed clinical trials or meta-analyses, and ginseng is no exception. In the present review, we discuss the functions of ginseng described in historical documents and describe how these functions are taken into account in herbal prescriptions. We also discuss the findings of experimental pharmacological research on the functions of ginseng in ginseng-containing prescriptions and how these prescriptions have been applied in modern therapeutic interventions. The present review on the functions of ginseng in traditional prescriptions helps to demystify ginseng and, as a result, may contribute to expanding the use of ginseng or ginseng-containing prescriptions.

Abstract
Background The traditional Japanese medicine juzentaihoto (JTX) is a pharmaceutical grade multi-herbal medicine widely used for the prevention of cancer metastasis and infection in immuno-compromized patients in Japan. The effect of JTX has been supposed to be intimately affected by the immunological properties of host and enteric microflora. The influence of JTX on the gene expression profile in the large and small intestines was investigated by microarray analyses using mice of different strains with or without enteric microflora. Results In all types of mice, including germfree (GF) animals, the genes most affected by two-week oral JTX treatment were the type 1 interferon (IFN)-related genes including Stat1, Isgf3g and Irf7, which play a critical role in the feedback loop of IFN-α production cascade. In IQI specific pathogen free (SPF) mice JTX increased the steady state level of the expression of IFN-related genes, but had the opposite effect in IQI GF and BALB/c SPF mice. Promoter analysis suggests that tandem repeated $IRFF (the promoter sequences for interferon regulatory factors) may be a primary target for JTX action. Pre-treatment of JTX accelerated the effects of an oral IFN "inducer" 2-amino-5-bromo-6-methyl-4-pyrimidinol (ABMP) (up-regulation of IFN-α production in IQI strain and down-regulation in BALB/c mice), which is in good accordance with the effect of JTX on gene expression of type 1 IFN-related genes. Conclusions Microarray analysis revealed that the target of JTX might be the transcription machinery regulating the steady-state level of genes involved in the ISGF3-IRF7 cascade, whose effect is bi-directional in a strain- and microbiota-dependent manner.

Abstract
The purpose of this study was to investigate the efficacy of four different Japanese and Chinese herbal prescriptions, Ren-Shen-Yang-Rong-Tang (Ninjin'yoeito, NYT), Chai-Hu-Gui-Zhi-Gan-Jiang-Tang (Saikokeishikankyoto, SKKT), Si-Jun-Zi-Tang (Shikunshito, SKT) and Si-Wu-Tang (Shimotsuto, SMT), which are traditionally used for anemia and fatigue, against hematotoxicity in mice treated with 5-fluorouracil (5-FU). NYT 1-100 mg kg(-1) day(-1) injected orally for 7 consecutive days before and after 5-FU injection significantly suppressed reductions in red blood cell, white blood cell and platelet counts in peripheral blood, and accelerated their recovery. Administration of SKKT also produced a slight but significant improvement in 5-FU-induced erythrocytopenia, whereas SMT and SKT could not prevent anemia. Oral injection of NYT also inhibited 5-FU-induced decreases in peripheral reticulocyte and bone marrow cell counts on day 10, and markedly hastened their recovery on day 20, in a dose-dependent manner. Erythroid progenitor colonies, such as colony forming units-erythroid and burst forming units-erythroid, formed by marrow cells from mice treated with 5-FU were significantly increased by oral administration of NYT. These findings suggest that NYT has the potential to protect against hematotoxicity, and also has hematopoietic activity, through stimulation of immature erythroid progenitor cell differentiation.

Abstract
AIM: Ribavirin (RBV) shows a strong antiviral effect on hepatitis C virus when used in combination with interferon. However, RBV-induced anemia is a major problem in this therapy. It would be of great clinical importance to ameliorate the anemia without reducing the RBV dose. We report here that, Ninjinyoeito (NYT), a herbal medicine can reduce the RBV-induced anemia.
METHODS: Twenty-three patients with chronic hepatitis C were treated with interferon alpha 2b plus RBV with (NYT group) or without (control group) NYT by a randomized selection. Eighteen patients completed the treatment schedule, and hemato-biochemical and virological effects were evaluated.
RESULTS: There was no significant difference in biochemical and virological responses between the two groups. However, anemia was significantly reduced in the NYT group compared with the control group. The maximal decrease of Hb in the NYT group (2.59 ± 1.10 g/dL) was significantly (P = 0.026) smaller than that in the control group (3.71 ± 0.97 g/dL). There was no significant difference in serum glutathione peroxidase activity, serum RBV concentration, and Th1/Th2 balance between the two groups. There was no specific adverse effect in NYT administration.
CONCLUSION: These results suggest that NYT could be used as a supportive remedy to reduce the RBV-induced anemia in the treatment of chronic hepatitis C.
