[PMID: 39151766 DOI: 10.1016/j.pep.2024.106579] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2024] [Revised: 08/01/2024] [Accepted: 08/14/2024] [Indexed: 08/19/2024]
Abstract
V. parahaemolyticus is a Gram-negative bacterium that causes gastroenteritis. Within the realm of bacterial interactions with the gut, the outer membrane protein MAM7 plays a key role. However, the precise function of MAM7 in intestinal inflammation, particularly its interactions with macrophages, remains unclear. In this study, we successfully expressed and purified recombinant MAM7. After optimization of the MAM7 expression condition, it was found that the optimal concentration and temperature were 0.75 mM and 15 °C, respectively, resulting in a 27-fold increase in its yield. Furthermore, RAW264.7 cytotoxicity assay was conducted. The CCK-8 results revealed that MAM7 substantially stimulated the proliferation of RAW264.7 cells, with its optimal concentration determined to be 7.5 μg/mL. Following this, the NO concentration of MAM7 was tested, revealing a significant increase (p < 0.05) in NO levels. Additionally, the relative mRNA levels of IL-1β, IL-6, and TNF-α in RAW264.7 cells were measured by qRT-PCR, showing a remarkable elevation (p < 0.05). Moreover, ELISA results demonstrated that MAM7 effectively stimulated the secretion of IL-6 and TNF-α by RAW264.7 cells. In summary, these findings strongly suggest that MAM7 serves as a proinflammatory adhesion factor with the capacity to modulate immune responses.

Abstract
The intestinal retention and persistence of lactic acid bacteria (LAB) are strain-specific and affected by the bacterial surface components. However, the contribution of surface adhesins of LAB to intestinal adhesion and colonization remains unclear. In the present study, seven gene knockout mutants (genes related to surface adhesin synthesis) of Lacticaseibacillus paracasei S-NB were derived based on the Cre-lox-based recombination system. Results showed that the capsule layer appeared thinner in the cell wall of S-NBΔ7576, S-NBΔdlt, and S-NBΔsrtA mutants when compared with the wild-type (WT) S-NB. The effects of S-NB_7576 (wzd and wze genes, responsible for capsular polysaccharide synthesis) and S-NB_srtA (sortase A) mutation on the hydrophobicity, surface charge, and adhesion ability seem to vary strongly among seven mutant strains. In vivo colonization experiments showed a decrease in the colonization numbers of S-NBΔ7576 and S-NBΔsrtA in both the ileal and colon lumen from 2 to 8 days when compared with those of the WT S-NB. In conclusion, the synthesis of capsular polysaccharides and the transport of surface proteins are closely related to the adhesion ability and intestinal colonization of L. paracasei S-NB.

Abstract
The galloyl group in catechins was confirmed to be crucial for their health benefits. However, whether the catechins' galloyl group had a contribution to their anti-inflammation remains unclear. This study investigated the anti-inflammation properties and mechanisms of catechins in RAW264.7 cells by using ELISA, fluorometry, flow cytometer, Western blot, and molecular docking. Results showed that the galloyl group enhanced the inhibitory abilities of catechins on inflammatory cytokines (NO, PGE2, IL-1β, and TNF-α) and ROS release in LPS-induced cells. This suppression was likely mediated by delaying cells from the G0/G1 to the S phase, blocking COX-2 and iNOS via the TLR4/MAPK/NF-κB pathway with PU.1 as an upstream target. The research proved that the existence of galloyl groups in catechins was indispensable for their anti-inflammatory capacities and offered a theoretical basis for the anti-inflammatory mechanism of galloylated catechins. Future research is needed to verify the anti-inflammatory effects of catechins in various sources of macrophages or the Caco-2/RAW264.7 cell co-culture system.

[PMID: 39104394 PMCID: PMC11298432 DOI: 10.3389/fphar.2024.1417372] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2024] [Accepted: 07/01/2024] [Indexed: 08/07/2024] Open
Abstract
Objective To investigate the anti-inflammatory activity and mechanism of Baicalin derivative (Baicalin butyl ester, BE). Methods BE was synthesized and identified using UV-Vis spectroscopy, FT-IR spectroscopy, mass spectrometry (MS) and high-performance liquid chromatography (HPLC) methods. Its anti-inflammatory potential was explored by an in vitro inflammation model. Network pharmacology was employed to predict the anti-inflammatory targets of BE, construct protein-protein interaction (PPI) networks, and analysis topological features and KEGG pathway enrichment. Additionally, molecular docking was conducted to evaluate the binding affinity between BE and its core targets. qRT-PCR analysis was conducted to validate the network pharmacology results. The organizational efficiency was further evaluated through octanol-water partition coefficient and transmembrane activity analysis. Results UV-Vis, FT-IR, MS, and HPLC analyses confirmed the successfully synthesis of BE with a high purity of 93.75%. In vitro anti-inflammatory research showed that BE could more effectively suppress the expression of NO, COX-2, IL-6, IL-1β, and iNOS. Network pharmacology and in vitro experiments validated that BE's anti-inflammatory effects was mediated through the suppression of SRC, HSP90AA1, PIK3CA, JAK2, AKT1, and NF-κB via PI3K-AKT pathway. Molecular docking results revealed that the binding affinities of BA to the core targets were lower than those of BE. The Log p-value of BE (1.7) was markedly higher than that of BA (-0.5). Furthermore, BE accumulated in cells at a level approximately 200 times greater than BA. Conclusion BE exhibits stronger anti-inflammatory activity relative to BA, possibly attributed to its better lipid solubility and cellular penetration capabilities. The anti-inflammatory mechanism of BE may be mediated through the PI3K-AKT pathway.

Abstract
Human milk oligosaccharides (HMOs) promote the growth and adhesion of bifidobacteria, thus exerting multiple biological functions on intestinal epithelial cells. Bacterial surface proteins play an important role in bacterial-host intestinal epithelial interactions. In this study, we aim to investigate the effects of surface proteins extracted from Bifidobacterium bifidum DNG6 (B. bifidum DNG6) consuming 2'-fucosyllactose (2'-FL) on Caco-2 cells monolayer barrier injury induced by lipopolysaccharide, compared with lactose (Lac) and galacto-oligosaccharides (GOS). Our results indicated that 2'-FL may promote the surface proteins of B. bifidum DNG6 to improve intestinal barrier injury by positively regulating the NF-κB signaling pathway, reducing inflammation(TNF-α reduced to 50.34%, IL-6 reduced to 22.83%, IL-1β reduced to 37.91%, and IL-10 increased to 63.47%)and strengthening tight junction (ZO-1 2.39 times, Claudin-1 2.79 times, and Occludin 4.70 times). The findings of this study indicate that 2'-FL can further regulate intestinal barrier damage by promoting the alteration of B. bifidum DNG6 surface protein. The findings of this research will also provide theoretical support for the development of synbiotic formulations.

Abstract
Probiotics have become increasingly popular as consumers demand balanced nutrition and health benefits from their diet. However, lactose intolerance and allergies to milk proteins may make dairy-based probiotics unsuitable for some individuals. Thus, probiotics derived from cereals and millets have shown promise as an alternative to dairy probiotics. Soaking, germination, and fermentation can reduce the anti-nutritional factors present in cereal grains and improve nutrient quality and bioactive compounds. Biochemical properties of probiotics are positively influenced by fermentation and germination. Thus, the current review provides an overview of the effect of fermentation and germination on the biochemical properties of probiotics. Further, probiotics made from non-dairy sources may prevent intestinal infections, improve lactose metabolism, reduce cholesterol, enhance immunity, improve calcium absorption, protein digestion, and synthesize vitamins. Finally, health-conscious consumers seeking non-dairy probiotic options can now choose from a wider variety of low-cost, phytochemically rich probiotics derived from germinated and fermented cereal grains.

Abstract
The bacterial surface components are considered as effector molecules and show the potential to support intestinal health, but the detailed mechanism of how the gut microbiota changes after the intervention of surface molecules is still unknown. In the present study, capsular polysaccharide (B-CPS) and surface layer protein (B-SLP) were extracted from Lacticaseibacillus paracasei S-NB. The protective effect of direct administration of B-CPS (100 μg/mL) and B-SLP (100 μg/mL) on intestinal epithelial barrier dysfunction was verified based on the LPS-induced Caco-2 cell model. Additionally, the B-CPS and B-SLP could be utilized as carbon source and nitrogen source for the growth of several Lactobacillus strains, respectively. The postbiotic potential of B-CPS and B-SLP was further evaluated by in vitro fermentation with fecal cultures. The B-CPS and a combination of B-CPS and B-SLP regulated the composition of gut microbiota by increasing the relative abundances of Bacteroides, Bifidobacterium, Phascolarctobacterium, Parabacteroides, Subdoligranulum and Collinsella and decreasing the abundance of pathogenic bacteria like Escherichia-Shigella, Blautia, Citrobacter and Fusobacterium. Meanwhile, the total short-chain fatty acid production markedly increased after fermentation with either B-CPS individually or in combination with B-SLP. These results provided an important basis for the application of B-CPS and B-SLP as postbiotics to improve human intestinal health.

Abstract
This research was designed to characterize the structure of Cyperus esculentus polysaccharide (CEP) and its acetylated one (ACEP), and then investigated the effects of acetylation on the changes in physicochemical properties, thermal stability, antioxidant and immunomodulatory activities. Results showed that CEP and ACEP were heteropolysaccharides consisting of glucose, mannose, arabinose and xylose. The main chain of CEP included α-1,4-Glcp residues with the branching points at the O-6 position of the α-1,6-Manp residues. Acetyl groups were substituted at the O-2 and O-6 positions of some glucose residues. Meanwhile, the acetylation remarkably improved the polysaccharides thermal stability, and the ACEP exhibited a greater antioxidant activity. Furthermore, CEP and ACEP were proved to protect RAW 264.7 cells against LPS-induced inflammation by improving cellular morphology and decreasing reactive oxygen species secretion. This study may highlight a new approach for developing a high value-added ingredient from C. esculentus for functional food industry.

Abstract
The oral microbiota, the second largest microbiome in the human body, plays an integral role in maintaining both the local oral and systemic health of the host. Oral microecological imbalances have been identified as a potential risk factor for numerous oral and systemic diseases. As a representative component of tea, epigallocatechin gallate (EGCG) has demonstrated inhibitory effects on most pathogens in single-microbial models. In this study, the regulatory effect of EGCG on more complex oral microbial systems was further explored through a mouse model of acetic acid-induced oral inflammation. Acetic acid induces histological damage in the cheek pouch, tongue, and throat, such as broken mucosa, submucosal edema, and muscular disorders. These detrimental effects were ameliorated significantly following EGCG treatment. Additionally, EGCG reduced the levels of the inflammatory cytokines interleukin-6 and tumor necrosis factor-α to alleviate the inflammation of the tongue, cheek pouch, and throat. According to the 16S rDNA gene sequencing data, EGCG treatment contributed to increased diversity of the oral microbiota and the reversal of oral microecological disorder. This study demonstrates the regulatory effect of EGCG on dysregulated oral microbiota, providing a potential option for the prevention and treatment of oral-microbiota-associated diseases.

Anti-inflammatory effect of Lactiplantibacillus plantarum T1 cell-free supernatants through suppression of oxidative stress and NF-κB- and MAPK-signaling pathways. Appl Environ Microbiol 2023; 89:e0060823. [PMID: 37702501 PMCID: PMC10617582 DOI: 10.1128/aem.00608-23] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2023] [Accepted: 07/08/2023] [Indexed: 09/14/2023] Open
Abstract
Lactiplantibacillus plantarum T1 is an isolated probiotic lactic acid bacterium (LAB) from pickled vegetables in Chongqing, China. In this study, we evaluated the anti-inflammatory activity and the underlying mechanisms of L. plantarum T1 cell-free supernatant (CFS) on lipopolysaccharide (LPS)-stimulated murine RAW264.7 macrophages in vitro. Reverse transcription quantitative PCR (RT-qPCR), immunofluorescence, Griess methods, and western blotting were utilized to assess the anti-inflammatory cytokines and antioxidative effect of L. plantarum T1 CFS. Our results showed that L. plantarum T1 CFS pretreatment significantly reduced pro-inflammatory cytokine levels, including nitric oxide, inducible nitric oxide synthase, cyclooxygenase-2, tumor necrosis factor, interleukin (IL)-1β, and IL-6, as well as reactive oxygen species. Interestingly, L. plantarum T1 CFS unregulated the antioxidant indicators, including superoxide dismutase, catalase, and glutathione in RAW264.7 cells. Furthermore, L. plantarum T1 CFS activated the nuclear factor kappa-B (NF-κB) and mitogen-activated protein kinase (MAPK) pathway. This study showed the excellent antioxidant and anti-inflammatory properties of L. plantarum T1 through multiple pathways, highlighting its potential for further research and application as a probiotic strain.IMPORTANCEL. plantarum T1 stood out in a series of acid and bile salt tolerance and bacterial inhibition tests as a probiotic isolated from paocai, which provides many health benefits to the host by inhibiting the growth of harmful pathogenic microorganisms and suppressing excessive levels of oxidative stress and inflammation. Not all LAB have good probiotic functions and are used in various applications. The anti-inflammatory antioxidant potential and mechanisms of L. plantarum T1 CFS have not been described and reported. By using RT-qPCR, Griess method, and western blotting, we showed that L. plantarum T1 CFS had anti-inflammatory and antioxidant effects. Griess assay, TBA assay, WST-8 assay, immunofluorescence assay, RT-qPCR, and western blotting data revealed that its anti-inflammatory and antioxidant mechanisms were associated with oxidative stress and NF-κB and MAPK signaling pathways. The anti-inflammatory and antioxidant effects of L. plantarum T1 CFS in paocai generates opportunities for probiotic product development.

Curr Res Food Sci 2023; 6:100520. [PMID: 37251637 PMCID: PMC10209677 DOI: 10.1016/j.crfs.2023.100520] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2023] [Revised: 05/12/2023] [Accepted: 05/15/2023] [Indexed: 05/31/2023] Open
Abstract
Bovine lactoferrin (LF) per 1 g was reacted with 0.16, 0.32, and 0.64 mg CuCl2 to reach 10%, 20%, and 40% copper-saturation, respectively, aiming to assess their anti-inflammatory activities to lipopolysaccharide (LPS)-stimulated RAW264.7 macrophages. The macrophages treated with CuCl2 at 0.051 μg/mL dose did not have obvious change in cell viability, lactate dehydrogenase (LDH) release, and intracellular reactive oxygen species (ROS) production. However, LF and Cu-fortified LF products (10-80 μg/mL doses) mostly showed inhibitory effects on the stimulated macrophages dose-dependently. Moreover, Cu-fortified LF products of lower Cu-fortifying levels at lower doses exerted weaker inhibition on the stimulated macrophages than LF, leading to higher cell viability but decreased LDH release. Meanwhile, LF and Cu-fortified LF products at 10 and 20 μg/mL doses showed different activities to the stimulated cells, via partly decreasing or increasing the production of inflammatory mediators namely prostaglandin E2 (PGE2), nitric oxide, tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), IL-1β, and ROS production, depending on the used Cu-fortifying and dose levels. Compared with LF, Cu-fortified LF product (Cu-fortifying level of 0.16 mg/g LF) at 10 μg/mL dose showed enhanced inhibition on the production of PGE2, ROS, IL-1β, and TNF-α, evidencing increased anti-inflammatory activity. However, the inhibition of Cu-fortified LF product (Cu-fortifying level of 0.32 mg/g LF) at 20 μg/mL dose on the production of these inflammatory mediators was mostly reduced. It is thus proposed that both Cu-fortifying and dose levels could affect LF's anti-inflammatory activity in LPS-stimulated macrophages, while the Cu-fortifying level of LF could govern activity change.

Abstract
Periodontitis and related systemic inflammatory diseases are characterized by imbalanced ratio between pro- and anti-inflammatory factors. Probiotics may control inflammation by altering the inflammatory phenotype of defense cells. We aimed to evaluate the gene transcription of the antibacterial response of monocytes to exposure to probiotic lactobacilli. CD14 + monocytes were obtained by positive selection from peripheral blood mononuclear cells from healthy donors (5 × 104 CD14 + /mL) and cultured with probiotic strains of Lacticaseibacillus rhamnosus (LR-32) and Lactobacillus acidophilus (LA-5) at a 1:10 multiplicity of infection in 24-well plates for 12 h. The gene expression analysis was performed by RT-qPCR using the Kit RT2 human antibacterial response, and in the supernatant, the cytokines were determined by ELISA. Tukey's post hoc test following an ANOVA with a p value of 5% was used for statistical analysis. Both probiotic strains increased the levels of cytokines TNF-α and CXCL-8 in the supernatant compared to the control of non-challenged cells (p < 0.05), but for IL-1Β and IL-6, this effect was observed only for LA-5 (p < 0.05). The fold-regulation values for the following genes for LA-5 and LR-32 were, respectively, IL-12B (431.94 and 33.30), IL-1Β (76.73 and 17.14), TNF-α (94.63 and 2.49), CXCL-8 (89.59 and 4.18), and TLR-2 (49.68 and 3.40). Likewise, most of the other genes evaluated showed greater expression for LA-5 compared to LR-32 (p < 0.05). The positive regulation of inflammatory factors such as IL-1β promoted by L. acidophilus LA-5 may increase the antibacterial activity of innate defense in periodontal tissues. However, this property may be deleterious by increasing inflammatory response.

High-fat diet in mice led to increased severity of spermatogenesis impairment by lead exposure: perspective from gut microbiota and the efficacy of probiotics.

Abstract
BACKGROUND The mechanism of multifactorial spermatogenesis impairment is unclear. This study aimed to investigate the reproductive toxicity of lead (Pb) in mice fed a high-fat diet (HFD) and to delineate the important role of gut microbiota. RESULTS Results showed that, compared with mice fed a normal diet (ND), Pb exposure caused more severe spermatogenesis impairment in HFD-fed mice, including decreased sperm count and motility, seminiferous tubule injury, serum and intratesticular testosterone decline, and downregulated expression level of spermatogenesis-related genes. Besides, 16S sequencing indicated that HFD-fed mice had increased severity of gut microbiota dysbiosis by Pb exposure compared to ND-fed mice. With fecal microbiota transplantation, the same trend of spermatogenesis impairment occurred in recipient mice, which confirmed the important role of gut microbiota. Moreover, probiotics supplementation restored the gut microbial ecosystem, and thus improved spermatogenic function. CONCLUSION Our work suggested that a population with HFD might face more reproductive health risks upon Pb exposure, and revealed an intimate linkage between microbiota dysbiosis and spermatogenesis impairment, accompanied by the potential usefulness of probiotics as prophylactic and therapeutic. © 2022 Society of Chemical Industry.

Abstract
In bacteria, as in other microorganisms, surface compounds interact with different pattern recognition receptors expressed by host cells, which usually triggers a variety of cellular responses that result in immunomodulation. The S-layer is a two-dimensional macromolecular crystalline structure formed by (glyco)-protein subunits that covers the surface of many species of Bacteria and almost all Archaea. In Bacteria, the presence of S-layer has been described in both pathogenic and non-pathogenic strains. As surface components, special attention deserves the role that S-layer proteins (SLPs) play in the interaction of bacterial cells with humoral and cellular components of the immune system. In this sense, some differences can be predicted between pathogenic and non-pathogenic bacteria. In the first group, the S-layer constitutes an important virulence factor, which in turn makes it a potential therapeutic target. For the other group, the growing interest to understand the mechanisms of action of commensal microbiota and probiotic strains has prompted the studies of the role of the S-layer in the interaction between the host immune cells and bacteria bearing this surface structure. In this review, we aim to summarize the main latest reports and the perspectives of bacterial SLPs as immune players, focusing on those from pathogenic and commensal/probiotic most studied species.

Abstract
Inflammatory bowel disease (IBD) is an inflammatory disease of the gastrointestinal tract, the incidence of which has rapidly increased worldwide, especially in developing and Western countries. Recent research has suggested that genetic factors, the environment, microbiota, and immune responses are involved in the pathogenesis; however, the underlying causes of IBD are unclear. Recently, gut microbiota dysbiosis, especially a decrease in the abundance and diversity of specific genera, has been suggested as a trigger for IBD-initiating events. Improving the gut microbiota and identifying the specific bacterial species in IBD are essential for understanding the pathogenesis and treatment of IBD and autoimmune diseases. Here, we review the different aspects of the role played by gut microbiota in the pathogenesis of IBD and provide a theoretical basis for modulating gut microbiota through probiotics, fecal microbiota transplantation, and microbial metabolites.

Abstract
Inflammatory bowel diseases (IBD), a heterogeneous group of inflammatory conditions that encompass both ulcerative colitis and Crohn's disease, represent a major public health concern. The etiology of IBD is not yet fully understood and no cure is available, with current treatments only showing long-term effectiveness in a minority of patients. A need to increase our knowledge on IBD pathophysiology is growing, to define preventive measures, to improve disease outcome, and to develop new effective and lasting treatments. IBD pathogenesis is sustained by aberrant immune responses, associated with alterations of the intestinal epithelial barrier (IEB), modifications of the enteric nervous system, and changes in microbiota composition. Currently, most of the treatments target the inflammation and the immune system, but holistic approaches targeting lifestyle and diet improvements are emerging. As dysbiosis is involved in IBD pathogenesis, pre-, pro-, syn-, and postbiotics are used/tested to reduce the inflammation or strengthen the IEB. The present review will resume these works, pointing out the stage of life, the duration, and the environmental conditions that should go along with microbiota or microbiota-derived treatments.

Abstract
Piperine, an important natural product, has a good anti-inflammatory effect. However, few researchers have studied its mechanism in these pathways. The objective of this research was to evaluate the molecular mechanism underlying the anti-inflammatory responses of piperine in lipopolysaccharide (LPS)-stimulated RAW264.7 cells. The purification and characterization of piperine from Piper nigrum L. were determined by HPLC, UPLC-Q-TOF-MS and 1H NMR. Then, the anti-inflammatory activity was evaluated by a reagent test kit, ELISA kits, RT-PCR and Western blot experiments. The results suggested that piperine (90.65 ± 0.46% purity) at a concentration of 10–20 mg/L attenuated the production of NO and ROS, downregulated the protein and mRNA expression levels of TNF-α, IL-1β and IL-6, and upregulated the protein and mRNA transcription levels of IL-10. Meanwhile, the Western blot results indicated that piperine could inhibit the phosphorylation levels of the ERK, JNK, p38 and p65 proteins. Our findings suggest that piperine is a potential anti-inflammatory substance, whose molecular mechanism may be to regulate the key factors of the NF-κB and MAPK signalling pathways.

Abstract
BACKGROUND The beneficial effects of probiotic supplementation standard antibiotic therapies for Helicobacter pylori infection have been verified, but the ability of probiotic monotherapy to eradicate H. pylori remains unclear. AIM To evaluate the accuracy and efficacy of specific Lactobacillus strains against H. pylori infection. METHODS Seventy-eight patients with H. pylori infection were treated with strain L. crispatus G14-5M (L. crispatus CCFM1118) or L. helveticus M2-09-R02-S146 (L. helveticus CCFM1121) or L. plantarum CCFM8610 at a dose of 2 g twice daily for one month. 14C-urea breath test, the gastrointestinal symptom rating scale, serum pepsinogen concentrations, and serum cytokine concentrations of patients were measured at baseline and end-of-trial to analyze the effect of the Lactobacillus strains in eradicating H. pylori infection and reducing gastrointestinal discomfort in patients. In addition, the composition and abundance of the intestinal microbiota of patients were also measured at end-of-trial. RESULTS The 14C-urea breath test value of the three Lactobacillus treatment groups had decreased significantly, and the eradication rate of H. pylori had increased by the end of the trial. In particular, the eradication rate in the G14-5M treatment group was significantly higher than the placebo group (70.59% vs. 15.38%, P=0.0039), indicating that one-month administration of the G14-5M regimen was sufficient to eradicate H. pylori infection. The ingestion of Lactobacillus strains also ameliorated the gastrointestinal symptom rating scale scores, and the serum interleukin-8 concentrations of H. pylori-infected patients appeared to modulate the gut microbiota of patients. However, none of the Lactobacillus strains had a significant effect on general blood physiological characteristics, serum tumor necrosis factor α concentrations, or serum pepsinogen concentrations in the patients. CONCLUSION Three Lactobacillus strains significantly alleviate the gastrointestinal discomfort and the gastric inflammatory response of H. pylori-infected patients. The activity of probiotics in eradicating H. pyloriinfection may be species/strain specific.

Abstract
BACKGROUND The intestinal epithelium is considered the first defense protection against exogenous harmful substances, playing an indispensable role in regulating intestinal health. The protection offered by surface-layer proteins (Slps) from different Lactobacillus strains on an impaired intestinal barrier was investigated in this study. RESULTS Four Slps pre-incubated for 6 h significantly prevented the reduced transepithelial electrical resistance value and increased paracellular permeability in tumor necrosis factor (TNF)-α-induced Caco-2 monolayers. TNF-α induced lower protein expression of occludin and zonula occludens-1, and abnormal distributions of occludin and zonula occludens-1 were ameliorated by four Slps as well. Additionally, four Slps weakened TNF-α-evoked interleukin-8 secretion and nuclear factor-κB activation. CONCLUSION Four Slps from different strains prevent the intestinal barrier from TNF-α-induced dysfunction through blocking the nuclear factor-κB signaling pathway. © 2022 Society of Chemical Industry.

Abstract
Rheumatoid arthritis (RA) is an inflammatory disease that seriously affects human health worldwide. Meanwhile, inflammation in RAW264.7 cells could lead to the progression of RA. Alkannin (ALK) is derived from Alkanna tinctoria and is known to exert anti-tumor effects. However, the function of ALK in inflammation of RAW264.7 cells remains unclear. Thus, this research sought to investigate the detailed function of ALK in inflammatory responses of RAW264.7 cells. To induce an inflammatory response, RAW264.7 cells were exposed to lipopolysaccharide (LPS). MTT assay was applied to examine cell viability. Enzyme-linked immunosorbent assay (ELISA) was used to assess the levels of inflammatory cytokines. Furthermore, the mechanism underlying ALK function in inflammatory responses was investigated using RT-qPCR and western blotting. The data revealed that LPS significantly increased the expression of cyclooxygenase 2 (COX-2), Interleukin (IL)-1β, inducible nitric oxide synthase (iNOS), tumor necrosis factor-α (TNF-α), and IL-6, whereas ALK reversed this effect. ALK also restored LPS-induced nuclear factor kappa-B (NF-κB) activation by inhibiting the downregulation of p-inhibitor kappa B alpha (IκBα). LPS elevated p-extracellular regulated protein kinases 1/2 (ERK1/2), phosphorylated p38 (p-p38), and phosphorylated -c-Jun N-terminal kinase (p-JNK) levels, which were markedly decreased in the presence of ALK. In summary, Alkannin attenuated LPS-induced inflammation by inhibiting NF-κB and MAPK signaling. Thus, our research might provide a new theoretical basis for exploring new strategies against RA.

Abstract
This paper focused on the mechanism of Ser-Ala-Gly-Pro-Ala-Phe (SAGPAF) treatment to improve gastric mucosal injury in mice. A gastric mucosa injury model induced by ethanol was established, and the superoxide dismutase (SOD) activity, malondialdehyde (MDA) content, nitric oxide (NO) content and myeloperoxidase (MPO) level were determined. We performed macroscopic and histopathological evaluation of the gastric organs. Moreover, we analyzed the mechanism of SAGPAF treatment by western blotting. Compared with the model group, the SOD activity and NO content in the medium-dose and high-dose SAGPAF groups of treated with 10 kV cm-1 field intensity were significantly increased. The MDA content and MPO level were decreased significantly. They significantly reduced the gastric mucosal injury induced by ethanol (21.17 ± 3.51% and 13.99 ± 2.00%) and the histopathological scores (3.83 ± 0.40 and 4.33 ± 0.37) (P < 0.05). Western blotting analysis showed that SAGPAF after pulsed electric field (PEF) treatment improved gastric injury by reducing protein phosphorylation. These findings provided strong evidence that PEF-treated SAGPAF enhanced the gastric mucosal barrier function by inhibiting the activation of the mitogen-activated protein kinase (MAPK) and nuclear factor kappa-B (NF-κB) signaling pathways, reducing the ethanol-induced inflammatory response and oxidative stress.

Abstract
Inflammatory bowel disease (IBD) is a chronic, relapsing gastrointestinal condition. Ulcerative colitis and Crohn’s disease are types of inflammatory bowel disease. Over many decades, the disease has been a topic of study, with experts still trying to figure out its cause and pathology. Researchers have established many in vivo animal models, in vitro cell lines, and ex vivo systems to understand its cause ultimately and adequately identify a therapy. However, in vivo animal models cannot be regarded as good models for studying IBD since they cannot completely simulate the disease. Furthermore, because species differences are a crucial subject of concern, in vitro cell lines and ex vivo systems can be employed to recreate the condition properly. In vitro models serve as the starting point for biological and medical research. Ex vivo and in vitro models for replicating gut physiology have been developed. This review aims to present a clear understanding of several in vitro and ex vivo models of IBD and provide insights into their benefits and limits and their value in understanding intestinal physiology.

Abstract
Inflammation is a host defense response to harmful agents, such as pathogenic invasion, and is necessary for health. Excessive inflammation may result in the development of inflammatory disorders. Levilactobacillus brevis KU15151 has been reported to exhibit probiotic characteristics and antioxidant activities, but the effect of this strain on inflammatory responses has not been determined. The present study aimed to investigate the anti-inflammatory potential of L. brevis KU15151 in Staphylococcus aureus lipoteichoic acid (aLTA)-induced RAW264.7 macrophages. Treatment with L. brevis KU15151 reduced the production of nitric oxide and prostaglandin E2 by suppressing the expression of inducible nitric oxide synthase and cyclooxygenase-2. Additionally, the production of proinflammatory cytokines including tumor necrosis factor-α, interleukin (IL)-6, and IL-1β, decreased after treatment with L. brevis KU15151 in aLTA-stimulated RAW 264.7 cells. Furthermore, this strain alleviated the activation of nuclear factor-κB and mitogen-activated protein kinase signaling pathways. Moreover, the generation of reactive oxygen species was downregulated by treatment with L. brevis KU15151. These results demonstrate that L. brevis KU15151 possesses an inhibitory effect against aLTA-mediated inflammation and may be employed as a functional probiotic for preventing inflammatory disorders.

Abstract
Jujube has great potential as food and traditional drugs in several countries. To study the anti-inflammatory influence of jujube peel polyphenols in lipopolysaccharide (LPS) induced RAW 264.7 cells through mitogen-activated protein kinase (MAPK), nuclear factor-kappa B (NF-κB) and nuclear erythroid 2-related factor 2 (Nrf2) signaling pathways. In this study, the phenolic composition of polyphenols in jujube peel was analyzed using LC-MS/MS, and which was confirmed that the main polyphenols were p-coumaric acid, catechin and rutin. Meanwhile, jujube peel polyphenols attenuated the generation of TNF-α, IL-1β, IL-6, NO and PGE2 by inhibiting MAPK and NF-κB signaling pathways. Additionally, jujube peel polyphenol activate Nrf2 from the cytoplasm to the nucleus, regulate antioxidant enzymes and pro-inflammatory cytokines, and reduce oxidative stress and inflammatory responses. Results obtained from this study suggest that jujube peel polyphenols may alleviate oxidative stress and inflammation by inhibiting MAPK and NF-κB and activating Nrf2 signaling pathways. Furthermore, jujube peel polyphenols have a synergistic effect in the treatment of LPS-induced inflammatory in RAW 264.7 cells. In conclusion, this study not only reveals the mechanism by which jujube peel polyphenols inhibit LPS-induced inflammation in RAW 264.7 cells, but also provides guidance for the development of new anti-inflammatory drugs.

Abstract
LPxTG-motif protein (LMP) is one kind of a precursor protein that contains a conserved LPxTG-motif at the C-terminus, which can be recognized by sortase A (SrtA) and covalently bind to the bacterial peptidoglycan. In this study, LMP derived from Lactobacillus reuteri (L. reuteri) was heterologous expressed and the tolerance and intestinal colonization ability of the LMP on L. reuteri were analyzed in simulated gastrointestinal fluid. Meanwhile, the anti-inflammatory activity of LMP was also evaluated in the LPS-stimulated RAW 264.7 cell model. The results indicated that LMP can promote the intestinal survival rate and adhesion characteristics of L. reuteri and enhanced the autoinducer-2 (AI-2) signaling molecule of the Lactobacillus strains in quorum sensing. Furthermore, LMP can inhibit the expressions of inflammatory cytokine TNF-α and IL-1β via ERK-JNK related MAPK signaling cascades. These findings provide a better understanding of the multifunctional LPxTG-motif surface protein derived from L. reuteri in the gastrointestinal tract environment.

Abstract
Various multi-drug-resistant microorganisms have appeared while a single antibacterial agent is increasingly no longer adequate for dealing with these resistant microorganisms. Herein, commercially purchased 50 nm-average-diameter silver nanoparticles (AgNPs) and Lactobacillus buchneri-isolated surface-layer proteins (SLPs) as a capping agent were used to fabricate a hybrid antibacterial agent (SLP-AgNPs) with enhanced antibacterial activity, and the possible synergistic antibacterial mechanism was explored. Characterization results revealed that SLP-AgNPs were uniformly surrounded by protein corona provided from SLP, and the formulations were mainly mediated by the electrostatic interactions and hydrogen bonding, which was evidenced by the results of Fourier transform infrared spectroscopy. According to the antibacterial tests, the minimum inhibitory concentration of SLP-AgNPs against Salmonella enterica (0.010 mg/mL) and Staphylococcus aureus (0.005 mg/mL) was 5-10 times lower than that of bare AgNPs, and while SLP-AgNPs showed a higher antibiofilm activity. Furthermore, bacterial cells exposed to SLP-AgNPs exhibited higher cell membrane permeability and stronger inhibition of respiratory-chain dehydrogenase activity, resulting in more severe cell death compared with bare AgNPs. The synergistic effect of SLP on AgNPs was probably carried out by enhanced function of adhesion to bacteria and antibacterial ability of SLP and SLP's supramolecular lattice structure on the sustained release of silver ion.

Abstract
Oxidative stress, which can cause imbalance in the body by damaging cells and tissues, arises from the immoderate production of reactive oxygen species (ROS)/reactive nitrogen species (RNS). Therefore, external supplements having antioxidant activity are required for reducing oxidative stress. In our study, we investigated DPPH and ABTS radical scavenging ability, and the inhibition effect on the nitric oxide (NO) production of 15 food-derived bacterial strains in LPS-activated RAW264.7 cells. Among these LAB strains, eight strains with an excellent inhibition effect on NO production were selected through comparisons within the same genera. Moreover, the selected strains, including Leuconostoc mesenteroides MG860, Leu. citreum MG210, Pediococcus acidilactici MG5001, P. pentosaceus MG5078, Weissella cibaria MG5090, Levilactobacillus brevis MG5306, Latilactobacillus curvatus MG5020, and Latilactobacillus sakei MG5048 diminished the inducible nitric oxide synthase (iNOS)/cyclooxygenase-2 (COX-2) expression. In addition, the stability and adhesion ability of the eight LAB strains in the gastrointestinal tract were determined. In conclusion, the selected strains have potential as new probiotics with antioxidant effects.

Abstract
In recent years, commensal bacteria colonizing the human body have been recognized as important determinants of health and multiple pathologic conditions. Among the most extensively studied commensal bacteria are the gut microbiota, which perform a plethora of functions, including the synthesis of bioactive products, metabolism of dietary compounds, and immunomodulation, both through attenuation and immunostimulation. An imbalance in the microbiota population, i.e., dysbiosis, has been linked to many human pathologies, including various cancer types and neurodegenerative diseases. Targeting gut microbiota and microbiome-host interactions resulting from probiotics, prebiotics, and postbiotics is a growing opportunity for the effective treatment of various diseases. As more research is being conducted, the microbiome field is shifting from simple descriptive analysis of commensal compositions to more molecular, cellular, and functional studies. Insight into these mechanisms is of paramount importance for understanding and modulating the effects that microbiota, probiotics, and their derivatives exert on host health.

Abstract
The purpose of this research was to explore the preventive effect of an 80% ethanol extract of Rhus chinensis Mill. fruits on dextran sulfate sodium (DSS)-induced colitis in mice and to elucidate the underlying molecular mechanisms of this effect. The results indicated that the extract, especially when administered at a high dose, could dramatically decrease the disease activity index, maintain normal spleen conditions, and improve colonic histopathology and length in the DSS-induced mice. In addition, extract administration could significantly suppress the levels of malondialdehyde, myeloperoxidase, tumor necrosis factor-α, interleukin-1β, and interleukin-6 and enhance superoxide dismutase and glutathione levels. The extract obviously protected intestinal barrier integrity by improving Occludin, ZO-1 and Claudin-1 expression levels. Western blot and immunohistochemistry analyses further indicated that the preventive effect of the phenol-rich extract on DSS-induced colitis might be achieved through the up-regulation of the expression of several pivotal oxidative stress-associated proteins, namely Nrf2, NQO1 and HO-1, and the down-regulation of the expression of several pivotal inflammation-associated proteins, namely p-NF-κB, p-IκB, COX-2, iNOS, p-P38, p-Erk1/2, and p-JNK. Therefore, R. chinensis fruits extract possesses the capability to prevent DSS-induced ulcerative colitis in mice and could be utilized as a natural substance in the exploitation of functional foods as an adjuvant dietary therapy for preventing and/or alleviating inflammatory bowel disease.

Abstract
This study aimed to investigate the protective effects of a < 3 kDa Tricholoma matsutake Singer peptide (TMWP) on lipopolysaccharide (LPS)-induced inflammation in RAW264.7 macrophages. The results showed that TMWP significantly upregulated superoxide dismutase (SOD) activity and reduced reactive oxygen species (ROS) generation in RAW264.7 macrophages. Western blotting and immunofluorescence analysis indicated that TMWP inhibited the activation of the mitogen-activated protein kinase (MAPK) and nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) pathways, thereby reducing the secretion of IL-1β and IL-6 and the expression of TNF-α, COX-2, and iNOS. Additionally, TMWP improved mitochondrial respiration in LPS-stressed macrophages, counteracting the harmful effects of LPS treatment on mitochondrial function. Three peptides (SDIKHFPF, SDLKHFPF, and WFNNAGP) with the highest predicted scores for potential anti-inflammatory activity were identified using nano-HPLC-MS/MS. These data indicated that T. matsutake peptides could be an attractive natural ingredient for developing novel functional foods.

Abstract
Lactobacillus species have been studied for over 30 years in their role as commensal organisms in the human gut. Recently there has been a surge of interest in their abilities to natively and recombinantly stimulate immune activities, and studies have identified strains and novel molecules that convey particular advantages for applications as both immune adjuvants and immunomodulators. In this review, we discuss the recent advances in Lactobacillus-related activity at the gut/microbiota interface, the efforts to probe the boundaries of the direct and indirect therapeutic potential of these bacteria, and highlight the continued interest in harnessing the native capacity for the production of biogenic compounds shown to influence nervous system activity. Taken together, these aspects underscore Lactobacillus species as versatile therapeutic delivery vehicles capable of effector production at the lumenal-mucosal interface, and further establish a foundation of efficacy upon which future engineered strains can expand.

Abstract
The search for functional foods containing probiotics has been growing due to numerous benefits they provide to health, such as modulation of the immune system and of the anti-inflammatory activity by inhibiting the release of pro-inflammatory cytokines, such as TNF-α. However, the mechanisms of actions of the probiotics responsible for this inhibition have not been completely explained so far. A better understanding of the interaction between probiotics and cell signaling pathways related to inflammatory processes shall help to prevent inflammatory bowel diseases. Therefore, the aim of this revision is to help understand the mechanisms of action of probiotics in cell signaling pathways that regulate TNF-α expression. Probiotics might act at different points of the MAPK pathway, on NF-kB, on proteasome activity, on Toll-like receptors, and on their regulators and stimuli. The present revision reaches the conclusion that probiotics act through multiple mechanisms, especially by inhibiting IkB phosphorylation and degradation, thus preventing the translocation of NF-kB. Effects are also shown to be strain-specific, and probiotics of the genus Lactobacillus are proved to play and essential role in anti-inflammatory activity.

Abstract
In recent years, studies on immunomodulation by surface-layer proteins (Slps) have mainly focused on Lactobacillus acidophilus, there is little information on Slp from L. crispatus and its intestinal immunomodulatory mechanisms in macrophages. In our study, the anti-inflammatory actions of Slp derived from L. crispatus JCM 2009 and its related molecular mechanisms were investigated. We initially found that incubation with Slp (5-10 μg/mL) for 4 h significantly inhibited nitric oxide (NO) and prostaglandin E2 (PGE2) production in LPS-stimulated RAW264.7 cells (P < 0.001). We then found that Slp inhibited the inflammatory response by regulating the PI3K/AKT/mTOR signaling pathway and activating autophagy in lipopolysaccharide (LPS)-stimulated RAW264.7 cells. Furthermore, ELISA and Western blotting results demonstrated that the NF-κB signaling pathway positively regulated autophagic activity to inhibit the productions of PGE2 and NO during this inflammatory response. And p65 was identified as a potentially important NF-κB signaling pathway molecule mediating the effects of Slp on the LPS-induced inflammatory response in RAW264.7 cells. Our findings provide the novel perspective that Slp exerts its anti-inflammatory effects through the activation of autophagy, making it a promising bioactive ingredient for the development of functional foods.

Abstract
Intestinal mucositis, a cytotoxic side effect of the antineoplastic drug 5-fluorouracil (5-FU), is characterized by ulceration, inflammation, diarrhea, and intense abdominal pain, making it an important issue for clinical medicine. Given the seriousness of the problem, therapeutic alternatives have been sought as a means to ameliorate, prevent, and treat this condition. Among the alternatives available to address this side effect of treatment with 5-FU, the most promising has been the use of probiotics, prebiotics, synbiotics, and paraprobiotics. This review addresses the administration of these "biotics" as a therapeutic alternative for intestinal mucositis caused by 5-FU. It describes the effects and benefits related to their use as well as their potential for patient care.

Abstract
Background This study was to investigate the cytokines and phenotype of macrophages pre-treated with class A1 scavenger receptor (SR-A1) antibody in vitro and the influence on apoptotic pathway of colonic epithelial cells, and to explore the role of SR-A1 mediated macrophages in impaired intestinal barrier of inflammatory bowel diseases (IBDs). Methods Mouse macrophage RAW264.7 was pre-treated with SR-A1 antibody in the presence of lipopolysaccharide (LPS). Transwell system was employed for co-culture of RAW264.7 and Caco-2 in the presence of LPS and IFN-γ, with or without SR-A1 antibody pre-treatment. The percentage of F4/80+CD11c+ macrophages, apoptosis rate of Caco-2 cells, and expression of apoptosis and tight junction proteins in Caco-2 cells was determined. Results Pre-treatment with SR-A1 antibody up-regulated IL-10 expression in RAW264.7, whereas down-regulated the expression of TNF and iNOS. Immunofluorescence staining indicated the upregulation of NF-κB p-p56 after LPS stimulation was significantly inhibited in the presence of SR-A1 antibody. The increase in p-JNK expression was inhibited by SR-A1 antibody. Transwell assay showed the percentage of F4/80+CD11c+ macrophages and apoptotic Caco-2 cells increased after treatment with LPS and IFN-γ, which could be reversed in the presence of SR-A1 antibody. The induction of cleaved caspase-3 and claudin-1 in Caco-2 cells was also suppressed when SR-A1 antibody pre-treatment. Conclusions Pre-treatment with SR-A1 antibody can inhibit inflammatory response in LPS-induced macrophages in a NF-κB dependent manner. Pre-treatment with SR-A1 antibody also inhibits M1 phenotype expression of macrophages, and attenuates the pro-apoptotic effect on colonic epithelial cells and disruption of intestinal barrier integrity induced by macrophages.

Abstract
A surface-layer protein (Slp) derived from Lactobacillus acidophilus NCFM has been reported to possess multiple biological properties, including anti-inflammatory, inhibition of apoptosis in pathogen-invaded HT-29 cells and oxidative stress relief. However, its anti-tumor ability and underlying molecular mechanism are unknown. Here, we report that Slp suppresses cell proliferation and induces autophagic cell death in HCT116 cells. Accumulation of Beclin-1 and microtubule-associated protein 1 light chain 3 from II (LC3-II), and the degradation of p62 were observed when cells were treated with various concentrations of Slp (25, 50, 100 μg mL-1) for 24 h. We also found that the mammalian targets of rapamycin (mTOR) and c-Jun N-terminal kinase (JNK) signaling pathways were crucial mediators regulating Slp-induced autophagic cell death. Additionally, treatment with Slp resulted in the obvious formation of reactive oxygen species (ROS). SP600125, a JNK inhibitor, and N-acetylcysteine (NAC), a ROS inhibitor, attenuated Slp-induced autophagic cell death in HCT116 cells. Furthermore, NAC was found to prevent Slp-induced p70 and JNK phosphorylation. Taken together, our results suggest a novel mechanism of action of Slp induced autophagy, acting simultaneously through the ROS-mediated mTOR and JNK signaling pathways in HCT116 colon cancer cells.

Abstract
The fruit of Akebia trifoliata is popular in Asia, but researches concerning the phytochemicals of A. trifoliate pericarp extract (APE) and their metabolites, bioavailability, metabolism and anti-inflammatory activity in vivo are less known. In the present study, the chemical constituents of APE and their metabolites of rats after oral administration were identified using UPLC-LTQ-Orbitrap-MS/MS. A total of 18 compounds were tentatively characterized in APE, while 8 original compounds and 8 metabolites were observed in plasma, and 10 original compounds and 39 metabolites were detected in urine. Deglycosylation, glucuronidation, methylation and sulfation were the reactions that mainly occurred in the metabolism in vivo. Meanwhile, APE supplementation decreased dextran sulphate sodium (DSS)-induced colitis in mice, ameliorating epithelial barrier disruption, suppressing the proliferation and infiltration of immune cells, modulating the secretion of nitric oxide (NO) and prostaglandin E2 (PGE2), decreasing the expression of nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) as well as regulating oxidative stress in vivo. The results suggested that APE triterpenoids and their metabolites as major contributors to anti-inflammatory activities, providing a scientific basis for the use of APE as a functional food to ameliorate colon health in humans.

Abstract
Soybean protein (Pro) and soybean oligopeptide (Pep) were subjected to simulated digestion in vitro to study the effect of Pep on the growth and metabolism of Lactobacillus acidophilus JCM 1132. First, the molecular weight distribution differences of samples before and after digestion were compared, and the samples were used to replace the nitrogen source components in the culture media. Then, the viable cell numbers, lactic acid and acetic acid content, differential metabolites, and metabolic pathways during the culturing process were measured. Results showed that the digested soybean oligopeptide (dPep) was less efficient than MRS medium in promoting the growth, but by increasing the content of the intermediates during the tricarboxylic acid (TCA) cycle, its metabolic capacity was significantly improved. Besides, due to the low molecular weight of dPep, it can be better transported and utilized. And dPep significantly strengthened the amino acid metabolism and weakened the glycerol phospholipid metabolism, so the ability of dPep in promoting the growth and metabolism of Lactobacillus acidophilus JCM 1132 is higher than the digested soybean protein (dPro). Exploring the effect of soybean oligopeptide on the growth and metabolism of Lactobacillus acidophilus JCM 1132 by metabolomics.![]()

Qi SR, Cui YJ, Liu JX, Luo X, Wang HF. Lactobacillus rhamnosus GG components, SLP, gDNA and CpG, exert protective effects on mouse macrophages upon lipopolysaccharide challenge. Lett Appl Microbiol 2019; 70:118-127. [PMID: 31782817 DOI: 10.1111/lam.13255] [Citation(s) in RCA: 23] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/26/2019] [Revised: 11/22/2019] [Accepted: 11/25/2019] [Indexed: 12/17/2022]
Abstract
The aim of this study was to determine whether Lactobacillus rhamnosus GG (LGG) components (surface layer protein, SLP; genomic DNA, gDNA; unmethylated cytosine-phosphate-guanine-containing oligodeoxynucleotide, CpG-ODN), alone or in combination, could affect immunomodulation, and evaluate the signalling mechanism in mouse macrophage RAW264.7 cells challenged with lipopolysaccharide (LPS). LGG components were used to treat cells before LPS stimulation. Cytokine and Toll-like receptor (TLR) expression were assessed using real-time quantitative PCR (RT-qPCR). Mitogen-activated protein kinase (MAPK), extracellular regulated protein kinase (ERK) and nuclear factor-kappa B (NF-κB) signalling pathways were evaluated using immunoblots and immunofluorescence. SLP or SLP + gDNA pre-treatment significantly reduced the LPS-induced mRNA expression of tumour necrosis factor alpha (TNF-α). Pre-treatment with LGG single components (SLP, gDNA or CpG) or their combinations (SLP + gDNA or SLP + CpG) significantly decreased the LPS-induced interleukin-6 (IL-6) mRNA level (P < 0·05). Pre-treatment with SLP or gDNA, alone or in combination, significantly suppressed LPS-induced TLR2 and TLR4 mRNA levels (P < 0·05). SLP pre-treatment also significantly decreased the LPS-induced expression of TLR9 (P < 0·05). Pre-treatment with LGG single components or combinations significantly suppressed the LPS-induced phosphorylation levels of ERK (P > 0·05). In conclusion, pre-incubation with LGG components, singly or in combination, generally inhibited the activation of TLR, MAPK and NF-κB signalling pathways in LPS-stimulated cells, leading to attenuated inflammatory cytokine TNF-α and IL-6 production. These results indicate that nonviable probiotic LGG components exert an anti-inflammation effect on epithelial cells. SIGNIFICANCE AND IMPACT OF THE STUDY: Lactobacillus rhamnosus GG (LGG) is widely used as probiotics. However, its main components are not well known for affecting immunomodulation. This study investigated the effects of pre-treatments with different components such as surface layer protein, genomic DNA and unmethylated cytosine-phosphate-guanine-containing oligodeoxynucleotides, alone or in combination on immunomodulation, and evaluated the signalling mechanism in mouse macrophage RAW264.7 cells challenged with lipopolysaccharide. Pre-incubation with components alone or in combination generally inhibited the activation of Toll-like receptor, mitogen-activated protein kinases, extracellular regulated protein kinases and nuclear factor-kappa B signalling pathways in lipopolysaccharide-stimulated cells, which generally leads to attenuated inflammatory cytokine interleukin-6 and tumour necrosis factor alpha production. These results indicate that nonviable probiotic LGG components exert an anti-inflammation effect on epithelial cells.

Abstract
Intestinal dysbiosis is associated with a large number of disease processes including necrotizing enterocolitis and late-onset sepsis in preterm infants and colic and antibiotic-associated diarrhea in term infants. Probiotic microbes are increasingly administered to infants with the intent of decreasing risk of these acute diseases as well as chronic diseases of childhood such as asthma and atopic disease. The mechanisms by which probiotics decrease inflammation, decrease intestinal permeability, alter the intestinal microbiota, and influence metabolism have been discovered through both in vitro studies and in vivo in animal models. We review key mechanisms by which probiotic microbes improve health with emphasis on recent discoveries in the field.

Abstract
Inflammatory bowel disease (IBD) is an emerging health problem associated with the dysregulation of the intestinal immune system and microbiome. Probiotics are able to reduce inflammatory responses in intestinal epithelial cells (IECs). However, entire signaling pathways and the interaction between different probiotics have not been well-documented. This study was designed to investigate the anti-inflammatory effects and mechanisms of single and combined probiotics. HT-29 cells were induced by lipopolysaccharide (LPS) and tumor necrosis factor (TNF)-α, treated with Lactobacillus acidophilus, Bifidobacterium animalis subsp. lactis or their combination and analyzed for inflammation-related molecules. Both L. acidophilus and B. animalis subsp. lactis reduced interleukin (IL)-8 secretion and the expressions of phosphorylated p65 nuclear factor-kappa B (p-p65 NF-κB), phosphorylated p38 mitogen-activated protein kinase (p-p38 MAPK), vascular cell adhesion molecule-1 (VCAM-1) and cyclooxygenase-2 (COX-2), while they increased toll-like receptor 2 (TLR2) expression. L. acidophilus did not decrease intercellular adhesion molecule-1 (ICAM-1) but enhanced the inhibitory efficacy of B. animalis subsp. lactis. Combined probiotics showed the best anti-inflammatory activity. These results suggest that L. acidophilus and B. animalis subsp. lactis may exert a potent anti-inflammatory effect through modulating TLR2-mediated NF-κB and MAPK signaling pathways in inflammatory IECs. Both strains, especially their combination, may be novel adjuvants for IBD therapy.

Molecules 2019; 24:molecules24020275. [PMID: 30642099 PMCID: PMC6359491 DOI: 10.3390/molecules24020275] [Citation(s) in RCA: 52] [Impact Index Per Article: 10.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2018] [Revised: 01/07/2019] [Accepted: 01/09/2019] [Indexed: 01/01/2023] Open
Abstract
5-Hydroxymethylfurfural (5-HMF) is found in many food products including honey, dried fruits, coffee and black garlic extracts. Here, we investigated the anti-inflammatory activity of 5-HMF and its underlying mechanisms in lipopolysaccharide (LPS)-stimulated RAW 264.7 cells. 5-HMF pretreatment ranging from 31.5 to 126.0 μg/mL reduced the production of nitric oxide (NO), prostaglandin E2 (PGE2) and pro-inflammatory cytokines (TNF-α, IL-1β and IL-6) in a concentration-dependent manner in LPS-stimulated cells. Moreover, 5-HMF-pretreated cells significantly down-regulated the mRNA expression of two major inflammatory mediators, nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) and suppressed the production of pro-inflammatory cytokines, as compared with the only LPS-stimulated cells. 5-HMF suppressed the phosphorylation of extracellular regulated protein kinases (ERK1/2), c-Jun N-terminal kinase (JNK), IκBα, NF-κB p65, the mammalian target of rapamycin (mTOR) and protein kinase B (Akt). Besides, 5-HMF was proved to inhibit NF-κB p65 translocation into nucleus to activate inflammatory gene transcription. These results suggest that 5-HMF could exert the anti-inflammatory activity in the LPS-induced inflammatory response by inhibiting the MAPK, NF-κB and Akt/mTOR pathways. Thus, 5-HMF could be considered as a therapeutic ingredient in functional foods.

Abstract
AIM The role of mucus-binding protein (MUB) on the adhesion activity and immunomodulatory effect of Lactobacillus acidophilus. MATERIALS & METHODS The current research mainly focuses on the adhesion and immune function of MUB from L. acidophilus. The structural characteristics and adhesion properties of MUB were analyzed in the intestinal cell models. RESULTS MUB can promote the aggregation and formation of a membrane-like morphology in L. acidophilus, which could increase the survival rate of L. acidophilus in gastrointestinal tract (GIT). Furthermore, MUB could trigger immune regulation and intestinal protection through the Toll-like receptor 4 (TLR4) signaling pathway and inhibit the activation of mitogen-activated protein kinase (MAPK) signaling pathway. CONCLUSION MUB of L. acidophilus is an important component involved in bacterial-mucus interactions and immunomodulatory effect in gastrointestinal tract.
