Abstract
Objectives Ulcerative colitis (UC) is a commonly recurrent inflammatory bowel disease. T helper 17 (Th17)/regulatory T (Treg) cell balance plays an essential role in UC progression. However, it is unknown whether curcumin chitosan microspheres (CCM) regulate the Th17/Treg cell balance. Materials and Methods The UC mouse model was established by administering 3% dextran sodium sulfate and treated with CCM. The influence of CCM on the Th17/Treg balance was detected using flow cytometry. Cell experiments were conducted to investigate the role and mechanism of IGF2BP1 in Th17/Treg balance. Results We revealed that CCM demonstrated a significant therapeutic effect on UC. CCM obviously decreased the Th17 cell percentage but boosted the Treg cell percentage in UC mice. CCM remarkably increased the mRNA expression of Foxp3 but suppressed RORγt and interleukin-10 mRNA expression. PCR array of RNA modification-related genes revealed that the m6A binding protein IGF2BP1 was a key molecule in CCM regulation of Th17/Treg balance. IGF2BP1 overexpression dramatically repressed the CCM-induced balance of Th17/Treg cell differentiation. Mechanically, IGF2BP1 targeted LRP5 and regulated LRP5 through m6A modification. Furthermore, the silencing of LRP5 canceled the suppressive effect of IGF2BP1 on Th17/Treg cell percentage. Conclusion CCM modulated the Th17/Treg balance through IGF2BP1-mediated m6A modification, thereby alleviating UC, and providing new ideas for the treatment of UC.

Abstract
Ulcerative colitis (UC) is one of types of inflammatory bowel disease with high recurrence. Recent studies have highlighted that microbial dysbiosis as well as abnormal gut immunity are crucial factors that initiate a series of inflammatory responses in the UC. Modulating the gut microbiota-intestinal immunity loop has been suggested as one of key strategies for relieving UC. Many Chinese herbal medicines including some of single herb, herbal formulas and the derived constituents have been reported with protective effect against UC through modulating gut microbiome and intestinal immunity. Some clinical trials have shown promising results. This review thus focused on the current knowledge on using Chinese herbal medicines for treating UC from the mechanism aspects of regulating intestinal homeostasis involving microbiota and gut immunity. The existing clinical trials are also summarized.

Compatibility between cold-natured medicine CP and hot-natured medicine AZ synergistically mitigates colitis mice through attenuating inflammation and restoring gut barrier. JOURNAL OF ETHNOPHARMACOLOGY 2023; 303:115902. [PMID: 36395977 DOI: 10.1016/j.jep.2022.115902] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/08/2022] [Revised: 10/28/2022] [Accepted: 10/31/2022] [Indexed: 06/16/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Ulcerative colitis (UC) is a nonspecific intestinal inflammation with complex pathogenesis. Traditional Chinese Medicine (TCM) formula consists of several TCM herbs following the principle of herbal property and compatibility. Our previous studies found that Huanglian Ganjiang decoction (HGD) exhibited anti-colitis capacity and the compatibility between hot-natured medicine and cold-natured medicine was main compatibility. However, the association between compatibility mechanism of HGD and its anti-colitis effect has not been fully illustrated yet. AIM OF STUDY Here, we would explore whether cold-natured medicine Coptis chinensis Franch. plus Phellodendron chinense C.K.Schneid. (CP) and hot-natured medicine Angelica sinensis (Oliv.) Diels plus Zingiber officinale Roscoe (AZ) in HGD respectively produce different impacts on UC, and exert synergistic effect on UC together. MATERIALS AND METHODS UPLC/MS-MS was used to qualitatively analyze chemical profiles of CP, AZ and CPAZ extracts. CPAZ-UC target network was constructed using network pharmacology. Colitis mice was induced by 3% DSS for 7 days and treated with CP, AZ and CPAZ for another 7 days. The levels of multiple cytokines and proportions of innate and adaptive immune cells were determined to assess inflammatory profiles. The leakage of FITC-dextran, expressions of tight junction proteins were detected for evaluation of gut barrier function. RESULTS CP, AZ and CPAZ could improve symptoms of colitis mice. CP showed superiority in reducing proportions of pro-inflammatory immune cells M1 cells, neutrophils, Th1 and Th17 cells, and levels of pro-inflammatory cytokines IFN-γ, IL-6, IL-10, TNF-α. In the contrast, AZ had advantage of elevating ratios of anti-inflammatory immune cells M2 and Treg cells as well as the production of anti-inflammatory cytokines IL-10 and TGF-β. In addition, CP and AZ synergistically regulated M1/M2 macrophage polarization and the following IL-6, IL-10, TNF-α, IFN-γ production, thereby restoring intestinal mucosal barrier. CONCLUSION Taken together, our study first demonstrated that cold-natured medicine CP and hot-natured medicine AZ took on different functions in treatment of colitis mice. Meanwhile, they exhibited synergistic effect on the alleviation of intestinal inflammation and reinforcement of gut barrier function and integrity.

Abstract
INTRODUCTION Inflammatory bowel disease (IBD) is an autoimmune disease involving various parts of the gastrointestinal (GI) tract, which includes Crohn's disease (CD) and ulcerative colitis (UC). Due to the contradictory results regarding the percentage of peripheral blood (PB) regulatory T cells (Tregs) in IBD patients, this meta-analysis aimed to determine the Tregs frequency in IBD patients. METHOD We searched PubMed, Web of Science, SCOPUS, and Google Scholar databases for relevant observational articles that analyzed and reported the frequency of PB Tregs in IBD patients and healthy control groups. After choosing the related articles by two reviewers, the data regarding the definition of Tregs and their frequencies in different groups were recorded. RESULT In 22 studies, the results showed a nonsignificant difference in the frequency of PB Tregs between IBD cases and control subjects (SMD: -0.27, 95 % CI: -0.78, 0.23). However, the frequency of CD4+CD25+CD127- (SMD: -0.89, 95 % CI: -1.52, -0.26) and CD4+CD25+FoxP3+ (SMD: -1.32, 95 % CI: -2.37, -0.26) Tregs were significantly lower in IBD cases, compared to healthy subjects. Also, UC cases and active IBD cases showed a significantly lower frequency of Treg cells, compared to controls and remission IBD cases, respectively (SMD: -0.68, 95 % CI: -1.24, -0.11 and SMD: -0.60, 95 % CI: -0.93, -0.27). CONCLUSION Our study highlighted a probable decrease of Tregs in IBD patients, especially the patients with active states of the disease. The decrease of Treg cells might cause an imbalance in the immune system and the over-activation of auto-immune responses against the digestive tract.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Licorice is widely used in traditional Chinese Medicine (TCM) for compound compatibility, which could reduce toxicity and increase efficacy of certain herbal medicine, and its active components prominently effects of inhibit of inflammation and regulate of immunity. AIM OF THE STUDY The study probed into the mechanism of the anti-inflammatory and immunomodulatory effects of licorice based on the domination of the T helper type 17/regulatory T cells (Th17/Treg) differentiation balance and the composition and structure of the intestinal flora through the nuclear factor kappa B (NF-κB) signaling pathway. MATERIALS AND METHODS BALB/c mice were inoculated with dextran sulfate sodium (DSS) to establish animal models of ulcerative colitis (UC). For the pharmacodynamic study, UC mice were observed for the anti-inflammatory effect of licorice water extraction (LWE) in vivo, including clinical observation and measurement of colon length. Hematoxylin-eosin (HE) staining was used to evaluate pathological conditions. Immunohistochemistry (IHC) and transmission electron microscopy (TEM) were performed to observe the intestinal barrier of the colons. Inflammatory cytokine levels were measured using with enzyme-linked immunosorbent assay (ELISA) kits. The proportions of T helper (Th) cells in the colons was assessed using flow cytometry. Gut microbiota diversity was detected using 16S ribosomal (r)DNA sequencing. In addition, Western blot (WB) assays were used to verify ROR-γt, Foxp3, TLR4, MyD88 and NF-κB expression according to a standard protocol. RESULTS LWE exerted a pharmacological anti-inflammatory effect by attenuating inflammation in the colonic tissues through affecting the protein expression of TLR4/MyD88/NF-κB, and increasing the expression of tight junction (TJ) protein in the colons, improving the integrity of the intestinal mucosal barrier in vivo. Moreover, LWE reversed the imbalance in Th17/Treg cells differentiation and influenced the protein expression of ROR-γt and Foxp3 in UC mouse colons. In particular, LWE significantly affected the diversity of the gut microbiota in UC mice, ameliorated the composition of dominant species, and significantly increased the type and quantity of probiotics. CONCLUSION Licorice tends to reduce inflammation and enhance the protective action of the intestinal mucosal barrier via the TLR4/MyD88/NF-κB signal transduction pathway and alter the imbalance of Th-cell differentiation. Notably, licorice may affect the diversity of intestinal microbiota and the content of beneficial bacteria in the colon, which is a potential mechanism for understanding anti-inflammatory and immunomodulatory effects in UC mice in vivo.

EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE : ECAM 2022; 2022:6132289.

Abstract
Sishen pill (SSP) is an old Chinese medicine used to treat colitis with spleen-kidney-yang deficiency (SKYD) syndromes. However, its exact mechanism of action has not yet been fully elucidated. The aim of this study was to evaluate the effects and potential mechanisms of SSP on colitis with SKYD syndromes in mice. Colitis with SKYD syndromes was induced by rhubarb, hydrocortisone, and dextran sulfate sodium (DSS), and treatment was provided with SSP. Flow cytometry was performed to examine the inflammatory dendritic cell (infDC) regulations of SSP. The changes in the gut microbiota (GM) and fecal metabolites post-SSP treatment were investigated using the combination of 16S rRNA sequencing and untargeted metabolomics. Additionally, we also examined whether SSPs could regulate the infDCs by modifying TLR4/NF-κB signaling pathways. Compared with the DSS group, the disease activity index, colonic weight, index of colonic weight, and colonic injury scores, as well as the levels of tumor necrosis factor (TNF)-α, interleukin (IL)-1β, IL-6, and IL-12p70 decreased significantly in the DSS + SSP group, while free triiodothyronine (FT3), free tetraiodothyronine (FT4), testosterone (TESTO), body weight change, colonic length, and the levels of IL-10 increased. Also, SSP decreased the amounts of CD103+CD11c+iNOS+, CD103+CD11c+TNF-α +, CD11c+CD103+CD324+, CD103+CD11c+MHC-II+, and CD103+CD11c+CD115+. Interestingly, 16S rRNA sequencing and untargeted metabolomics showed that SSP treatment restored the dysbiosis of GM and improved the dysfunction in fecal metabolism in colitis mice with SKYD syndromes. Correlation analysis indicated that the modulatory effects of SSP on FT3, FT4, IL-10, colonic weight index, CD103+CD11c+TNF-α +, CD103+CD11c+MHC-II+, and 13 common differential metabolites were related to alterations in the abundance of Parvibacter, Aerococcus, norank_f_Lachnospiraceae, Lachnospiraceae_UCG-006, Akkermansia, and Rhodococcus in the GM. In addition, SSP markedly inhibited the activation of the TLR4, MyD88, TRAF6, TAB2, and NF-κBp65 proteins and activated IκB. These results indicate that SSP can effectively alleviate colitis mice with SKYD syndrome by regulating infDCs, GM, fecal metabolites, and TLR4/NF-κB signaling pathways.
