Abstract
Maternal obesity increases the risk of obesity and metabolic disorders (MDs) in offspring, which can be mediated by the gut microbiota. Phlorizin (PHZ) can improve gut dysbiosis and positively affect host health; however, its transgenerational metabolic benefits remain largely unclear. This study aimed to investigate the potential of maternal PHZ intake in attenuating the adverse impacts of a maternal high-fat diet on obesity-related MDs in dams and offspring. The results showed that maternal PHZ reduced HFD-induced body weight gain and fat accumulation and improved glucose intolerance and abnormal lipid profiles in both dams and offspring. PHZ improved gut dysbiosis by promoting expansion of SCFA-producing bacteria, Akkermansia and Blautia, while inhibiting LPS-producing and pro-inflammatory bacteria, resulting in significantly increased fecal SCFAs, especially butyric acid, and reduced serum lipopolysaccharide levels and intestinal inflammation. PHZ also promoted intestinal GLP-1/2 secretion and intestinal development and enhanced gut barrier function by activating G protein-coupled receptor 43 (GPR43) in the offspring. Antibiotic-treated mice receiving FMT from PHZ-regulated offspring could attenuate MDs induced by receiving FMT from HFD offspring through the gut microbiota to activate the GPR43 pathway. It can be regarded as a promising functional food ingredient for preventing intergenerational transmission of MDs and breaking the obesity cycle.

Biochem Biophys Rep 2023; 34:101475. [PMID: 37197734 PMCID: PMC10183655 DOI: 10.1016/j.bbrep.2023.101475] [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: 12/16/2022] [Revised: 03/18/2023] [Accepted: 04/19/2023] [Indexed: 05/19/2023] Open
Abstract
Background It remains unclear whether goblet cell numbers in offspring are altered by maternal nutritional status and/or early weaning. Herein, using a murine model, we clarified whether a low-protein (LP) diet during pregnancy and/or early weaning changes villus structures, goblet cell numbers, mucin intensity, and mucin mRNA expression in the mucosal layer throughout the intestines in mice offspring. Methods We examined villus-crypt structures and goblet cell numbers using hematoxylin-eosin staining. By performing alcian blue-PAS staining and RT-qPCR, we investigated mucin intensity in the mucosal layer and mRNA expressions of Muc2 and Muc4, respectively, in 17 (early weaning)-, 21 (normal weaning)- and 28-day old mice born from LP diet-fed mothers or those born from control diet-fed mothers during pregnancy. Results Dietary protein restriction reduced goblet cell numbers in throughout the intestine, particularly in the duodenum and jejunum, and mucin intensity in the mucosal layer at the border of the jejunum and colon. The LP diet increased villus height and decreased villus thickness throughout the small intestine and crypt depth and width in the cecum and colon. Conclusions Dietary protein restriction during pregnancy and/or early weaning decreased the number of goblet cells, mucin intensity in the mucosal layer, and the Muc2 and Muc4 mRNA expressions in the small and large intestines, and affected the villus and crypt structures in the small and large intestines in female offspring mice during and after weaning. General significance Dietary abnormalities in fetal and weaning periods affects intestinal function.

Abstract
Background and aim Although studies have associated elevated prenatal obesity with increased risk of various diseases in offspring, little is known regarding the immune system. The aim of this study was to evaluate the relationship between prenatal obesity and levels of cytokines in umbilical cord blood and development of allergic disease during the first 10 years of life in an offspring. Methods A cohort of term infants born at the ShaoXing Women and Children Hospitals in China in 2011 was enrolled in this study. Flow cytometry was performed to measure levels of various cord blood cytokines, namely IL1β, IL2, IL10, IL6, IL8, IL17, IL12, TNF-α and IFN-γ. Next, logistic regression was used to explore the association of prenatal BMI with the development of allergic disease. The relationship between levels of each cord blood cytokine with prenatal BMI, and allergic disease development was tested using linear and logistic regression analyses, respectively. Results After 10 years of follow-up, higher prenatal BMI was significantly associated with development of allergic disease in children (HR = 2.45, 95% CI:1.08-5.57, P = 0.033). We also adjusted for maternal age, education and infant gender, and found that prenatal BMI was significantly associated with higher levels of IL12 (P = 0.023) and IL1β (P = 0.049) in cord blood. Moreover, we adjusted for maternal age, education, allergic dermatitis, gestation age and infant gender, and found that increase in each unit (1.26 pg/ml) in IL17 was associated with a 55.5% higher risk of allergic disease in 10-year-old children (HR = 1.55, 95%Cl: 0.99-2.45, P = 0.056). Meanwhile, after adjusting for maternal age, education level, gestation age, prenatal BMI, gestational weight gain, infant gender and birthweight, we found that for every unit increase in IL10, IL6 and IL1β, the risk of overweight/obesity in children after 10-year follow-up increased by 18.7% (HR = 1.19, 95%Cl: 1.01-1.40, P = 0.042), 13.9% (HR = 1.14, 95%Cl: 1.02-1.27, P = 0.021) and 41.3% (HR = 1.41, 95%Cl: 1.02-1.95, P = 0.036), respectively. Conclusions Prenatal obesity was positively correlated with allergic diseases in offspring. Cord blood cytokine may play mediating roles in the associations of prenatal obesity with offspring allergic diseases.

Abstract
A high-fat diet plays a key role in the pathogenesis of colorectal cancer, and this effect on the gut can also occur in the offspring of mothers with a high-fat diet. In this review, we discuss the role of a high-fat diet in the pathogenesis of colorectal cancer and summarize the effects of a maternal high-fat diet on the activation of inflammation and development of colorectal cancer in offspring. Studies have found that a maternal high-fat diet primarily induces an inflammatory response in the colorectal tissue of both the mother herself and the offspring during pregnancy. This leads to the accumulation of inflammatory cells in the colorectal tissue and the release of inflammatory cytokines, which further activate the NF-κb and related inflammatory signaling pathways. Research suggests that high levels of lipids and inflammatory factors from mothers with a high-fat diet are passed to the offspring through the transplacental route, which induces colorectal inflammation, impairs the intestinal microecological structure and the intestinal barrier, and interferes with intestinal development in the offspring. This in turn activates the NF-κb and related signaling pathways, which further aggravates intestinal inflammation. This process of continuous inflammatory stimulation and repair may promote the uncontrolled proliferation of colorectal mucosal cells in the offspring, thus increasing their susceptibility to colorectal cancer.

Abstract
Background Commensal gut bacteria, including Lactobacillus, can produce metabolites that stimulate the release of gut antimicrobial peptides (AMPs) via the signal transducer and activator of transcription (STAT)3 pathway and prevent obesity-associated leaky gut and chronic inflammation. We have previously reported that wheat germ (WG) selectively increased cecal Lactobacillus in obese mice. Objectives This study investigated the effects of WG on gut STAT3 activation and AMPs (Reg3γ and Reg3β) as well as the potential of WG to inhibit nuclear Nf-κB-activation and immune cell infiltration in the visceral adipose tissue (VAT) of mice fed a Western diet (i.e., high-fat and sucrose diet [HFS]). Methods Six-wk-old male C57BL/6 mice were randomly assigned to 4 groups (n = 12/group): control (C, 10% fat and sucrose kcal) or HFS (45% fat and 26% sucrose kcal) diet with or without 10% WG (wt/wt) for 12 wk. Assessments include serum metabolic parameters jejunal AMPs genes, inflammatory markers, and phosphorylation of STAT3 as well as VAT NF-κBp65. Independent and interaction effects of HFS and WG were analyzed with a 2-factor ANOVA. Results WG significantly improved markers of insulin resistance and upregulated jejunal Il10 and Il22 genes. The HFS + WG group had a 15-fold increase in jejunal pSTAT3 compared with the HFS group. Consequently, WG significantly upregulated jejunal mRNA expression of Reg3γ and Reg3β. The HFS group had a significantly higher VAT NF-κBp65 phosphorylation than the C group, while the HFS + WG group suppressed this to the level of C. Moreover, VAT Il6 and Lbp genes were downregulated in the HFS + WG group compared with HFS. Genes related to macrophage infiltration in the VAT were repressed in the WG-fed mice. Conclusion These findings show the potential of WG to influence vital regulatory pathways in the gut and adipose tissue which may reduce the chronic inflammatory burden on these tissues that are important targets in obesity and insulin resistance.

Abstract
Obesity in pregnancy is currently the leading cause of gestational complications for the mother and fetus worldwide. Maternal obesity (MO), common in western societies, impedes development of intestinal epithelium in the fetuses, which causes disorders in the nutrient absorption and intestine-related immune responses in offspring. Here, using a mouse model of maternal exercise (ME), we found that exercise during pregnancy protects the impairment of fetal intestinal morphometrical formation and epithelial development due to MO. MO decreased villus length and epithelial proliferation markers in E18.5 fetal small intestine, which was increased due to ME. The expression of the epithelial differentiation markers, Lyz1, Muc2, and Tff3, in fetal small intestine was decreased due to MO, but protected by ME. Consistently, the biomarkers related to mitochondrial biogenesis and oxidative metabolism were downregulated in MO fetal small intestine but recovered by ME. Apelin injection to dams partially mirrored the beneficial effects of ME. ME and apelin injection activated AMPK, the downstream target of apelin receptor signaling, which might mediate the improvement of fetal epithelial development and oxidative metabolism. These findings suggest that ME, a highly accessible intervention, is effective in improving fetal intestinal epithelium of obese dams. Apelin-AMPK-mitochondrial biogenesis axis provides amenable therapeutic targets to facilitate fetal intestinal development of obese mothers.

Abstract
Obesity is a complex metabolic condition considered a worldwide public health crisis, and a deeper mechanistic understanding of obesity-associated diseases is urgently needed. Obesity comorbidities include many associated cancers and are estimated to account for 20% of female cancer deaths in the USA. Breast cancer, in particular, is associated with obesity and is the focus of this review. The exact causal links between obesity and breast cancer remain unclear. Still, interactions have emerged between body mass index, tumor molecular subtype, genetic background, and environmental factors that strongly suggest obesity influences the risk and progression of certain breast cancers. Supportive preclinical research uses various diet-induced obesity models to demonstrate that weight loss, via dietary interventions or changes in energy expenditure, reduces the onset or progression of breast cancers. Ongoing and future studies are now aimed at elucidating the underpinning mechanisms behind weight-loss-driven observations to improve therapy and outcomes in patients with breast cancer and reduce risk. This review aims to summarize the rapidly emerging literature on obesity and weight loss strategies with a focused discussion of bariatric surgery in both clinical and preclinical studies detailing the complex interactions between metabolism, immune response, and immunotherapy in the setting of obesity and breast cancer.

Abstract
BACKGROUND Maternal diet during pregnancy can impact progeny health and disease by influencing the offspring's gut microbiome and immune development. Gut microbial metabolism generates butyrate, a short-chain fatty acid that benefits intestinal health. Here we assess the effects of antenatal butyrate on the offspring's gastrointestinal health. We hypothesized that antenatal butyrate supplementation will induce protection against colitis in the offspring. METHODS C57BL/6 mice received butyrate during pregnancy and a series of experiments were performed on their offspring. RNA sequencing was performed on colonic tissue of 3-week-old offspring. Six-8-week-old offspring were subjected to dextran sulfate sodium-induced colitis. Fecal microbiome analysis was performed on the 6-8-week-old offspring. RESULTS Antenatal butyrate supplementation dampened transcript enrichment of inflammation-associated colonic genes and prevented colonic injury in the offspring. Antenatal butyrate increased the offspring's stool microbiome diversity and expanded the prevalence of specific gut microbes. CONCLUSIONS Antenatal butyrate supplementation resulted in downregulation of genes in the offspring's colon that function in inflammatory signaling. In addition, antenatal butyrate supplementation was associated with protection against colitis and an expanded fecal microbiome taxonomic diversity in the offspring. IMPACT Dietary butyrate supplementation to pregnant mice led to downregulation of colonic genes involved in inflammatory signaling and cholesterol synthesis, changes in the fecal microbiome composition of the offspring, and protection against experimentally induced colitis in the offspring. These data support the mounting evidence that the maternal diet during pregnancy has enduring effects on the offspring's long-term health and disease risk. Although further investigations are needed to identify the mechanism of butyrate's effects on fetal gut development, the current study substantiates the approach of dietary intervention during pregnancy to optimize the long-term gastrointestinal health of the offspring.

Abstract
OBJECTIVES Intestinal flora is considered closely related to the occurrence of inflammatory bowel disease (IBD). This study aimed to discover whether diverse diet conditions during early life lead to different intestinal flora structure and impact different susceptibility to IBD. METHODS We performed a randomized, controlled trial to investigate the relationship between maternal diet, intestinal flora, and susceptibility of IBD in offspring mice. We treated the maternal mice with different dietary conditions (maternal high fat, high protein, or normal diet, and offspring continued maternal diets or changed to normal diet), and then extracted bacterial meta-genomic DNA from the intestinal mucosa of the offspring during the early life and adult stages. We amplified and sequenced the conserved gene v3-v4 of the bacterial 16 S ribosomal RNA. After dextran sulphate sodium intervention, we evaluated the susceptibility to intestinal inflammation with hematoxylin and eosin stains and disease activity index scores. RESULTS The number of species and alpha diversity of weaning mice (3 wk old) fed a maternal high-protein diet were significantly lower than those of the control diet group (P < 0.05). Among adult (8 wk old) offspring rats, the alpha diversity of mice that continued on a high-protein diet remained significantly decreased (P < 0.05). In addition, 12 kinds of weak bacteria were found in weaning mice fed a maternal high-protein diet compared with the control group. Offspring that continued in the maternal high-protein group had increased disease activity index and pathologic scores after weaning. CONCLUSIONS In general, our study shows that a maternal high-protein diet during early life can negatively regulate the intestinal flora diversity of offspring mice. A high-protein diet during early life led to higher susceptibility of IBD in offspring rats.

Abstract
The present study aims to investigate the roles of scutellarin (SCU) on acute alcohol intestinal injury. Mice were divided into six groups: alcohol, three administration, negative control and positive drug bifendate control. The administration group mice were intraperitoneally injected with SCU for 3 consecutive days followed by alcohol gavage at an interval of 1 h. After the mice were sacrificed, colon tissue damage was evaluated by histopathological examination; the activities of inducible nitric oxide synthase (iNOS) and catalase (CAT), as well as the content of malondialdehyde (MDA) were detected using biochemical kits; the levels of inflammatory cytokines mRNA were determined by real-time fluorescence quantitative PCR; the protein expression levels of hemeoxygenase-1 (HO-1) and phosphorylated nuclear factor-ĸB p65 were measured via western blotting. The results showed that alcohol induced severe colon morphological degradation, epithelia atrophy, and more inflammatory cells infiltration in the submucosa. SCU treatment prevented this process, especially in the middle and high dose groups. Alcohol treatment caused excessive lipid peroxidation product accumulation of MDA, restrained the activity of antioxidant enzyme CAT, induced HO-1 expression in the colon, whereas low dose SCU treatment significantly down-regulated the MDA level, enhanced the CAT level, and accelerated HO-1 signals. SCU prevented alcohol stimulation triggered inflammatory response in colon tissues through significantly downregulating the iNOS activity, transcript levels of Tnf-α, Il-1β and Il-6, and phosphorylation levels of NF-κB p65. These findings suggest that SCU protects the colon via antioxidant and anti-inflammatory mechanisms, making it a promising drug against alcohol-induced colon damage.

Abstract
The immature immune system at birth and environmental stress increase the risk of infection in nursing pigs. Severe infection subsequently induces intestinal and respiratory diseases and even cause death of pigs. The nutritional and physiological conditions of sows directly affect the growth, development and disease resistance of the fetus and newborn. Many studies have shown that providing sows with nutrients such as functional oligosaccharides, oils, antioxidants, and trace elements could regulate immunity and the inflammatory response of piglets. Here, we reviewed the positive effects of certain nutrients on milk quality, immunoglobulin inflammatory response, oxidative stress, and intestinal microflora of sows, and further discuss the effects of these nutrients on immunity and the inflammatory response in the offspring.

Abstract
The etiopathogenesis of the autoimmune disease type 1 diabetes (T1D) is still largely unknown, however, both genetic and environmental factors contribute to the development of the disease. A major contact surface for environmental factors is the gastrointestinal (GI) tract, where barrier defects in T1D likely cause diabetogenic antigens to enter the body tissues, contributing to beta-cell autoimmunity. Human and animal research imply that increased intestinal permeability is an important disease determinant, although the underlying methodologies, interpretations and conclusions are diverse. In this review, an updated comprehensive overview on intestinal permeability in patients with T1D and animal models of T1D is provided in the categories: in vivo permeability, ex vivo permeability, zonulin, molecular permeability and blood markers. Across categories, there is consistency pointing towards increased intestinal permeability in T1D. In animal models of T1D, the intestinal permeability varies with age and strains implying a need for careful selection of method and experimental setup. Furthermore, dietary interventions that affect diabetes incidence in animal models does also impact the intestinal permeability, suggesting an association between increased intestinal permeability and T1D development.

Abstract
Alteration of programming of the intestinal wall maturation may be responsible for non-communicable chronic diseases in adulthood. It may originate from prenatal exposure of mothers to deleterious environmental factors such as pesticides or western diet. This work was undertaken to determine whether disturbances of the digestive tract function and of innate immunity of offspring at adulthood could be due to maternal exposure to a pesticide, chlorpyrifos (CPF) and a High Fat Diet (HFD) starting 4 months before gestation and lasting until weaning of offspring. Fifty-one male Wistar rats coming from 4 groups of dams exposed to CPF, HFD, both and control were followed from birth to 8 weeks of age. They were fed standard chow and received no treatment. The maternal pesticide exposure slows down fetal and postnatal weight gain without histological injuries of the gut mucosa. CPF or HFD both induced modifications of tight junctions and mucins genes expressions without inducing an increase in epithelial permeability or an inflammatory state. Co-exposure to both CPF and HFD did not exacerbate the effects observed with each factor separately. Despite the lack of direct contact except through breast milk until weaning, CPF or HFD maternal exposure have demonstrated preliminary gut barrier impacts on offspring.

Abstract
Preeclampsia is a devastating hypertensive pregnancy disorder that currently affects 2%–8% of pregnancies worldwide. It is associated with maternal and fetal mortality and morbidity and adverse health outcomes both in mom and offspring beyond pregnancy. The pathophysiology is not completely understood, and there are no approved therapies to specifically treat for the disease, with only few therapies approved to manage symptoms. Recent advances suggest that aberrations in the composition of the microbiome may play a role in the pathogenesis of various diseases including preeclampsia. The maternal and uteroplacental environments greatly influence the long‐term health outcomes of the offspring through developmental programming mechanisms. The current review summarizes recent developments on the role of the microbiome in adverse pregnancy outcomes with a focus on preeclampsia. It also discusses the potential role of the maternal microbiome in fetal programming; explores gut‐targeted therapeutics advancement and their implications in the treatment of preeclampsia.

Abstract
Background Excessive fluoride can lead to chronic neurodegeneration characterized by neuron and myelin loss and memory dysfunction. The gut–brain axis hypothesis suggests that gut microbiota plays a crucial role in regulating brain function. Thus, using probiotics to adjust the gut microenvironment may be a potential therapy for mental diseases. Methods Mice in the prob group were administrated with Lactobacillus johnsonii BS15 for 28 days prior to and throughout a 70-day exposure to sodium fluoride. The drinking water of all groups (F and prob groups) except the control group were replaced by high-fluoride water (100 mg NaF/L) on day 28. Animals in each group were divided into two subsets: one underwent behavioral test, and the other was sacrificed for sampling. The mRNA expression level and protein content related to inflammatory reaction in the ileum and hippocampus were respectively detected by reverse transcription quantitative polymerase chain reaction (RT-qPCR) and enzyme-linked immunosorbent assay (ELISA). The mRNA expression levels of proteins related to myelin structure, apoptosis, and memory in the hippocampus and tight junction proteins in the ileum were determined by RT-qPCR and/or immunohistochemistry. Gut permeability markers (D-lactate and diamine oxidase (DAO)) in the serum were also examined by ELISA. Results The results showed that fluoride exposure induced a lower spontaneous exploration (P < 0.05) in T-maze test, which indicated an impairment of memory. Spontaneous exploration of BS15-treated mice was significantly higher (P < 0.05) than that in F group. Fluoride reduced (P < 0.05) levels of myelin structural protein (proteolipid protein) and neurogenesis-associated proteins (brain-derived neurotrophic factor and cAMP/Ca2+ responsive element-binding protein), induced disordered inflammatory cytokines (TNF-α, IFN-γ, and IL-6; P < 0.05), increased pro-apoptotic genes (caspase-3; P < 0.05), and decreased anti-apoptotic genes (Bcl-2; P < 0.05) in the hippocampus, of which the influences were reversed by BS15. BS15 treatment exerted significant preventive effects on reversing the gut inflammation induced by excessive fluoride intake by reducing (P < 0.05) the levels of pro-inflammatory cytokines (tumor necrosis factor-alpha (TNF-α) and interferon-gamma (IFN-γ)) and remarkably increasing (P < 0.05) the level of anti-inflammatory cytokines (IL-10). Moreover, the serum DAO activity and D-lactate concentration significantly increased by fluoride were also reduced (P < 0.05) by BS15. This result indicated the profitable effect of BS15 on gut permeability. Conclusion L. johnsonii BS15 intake could benefit the neuroinflammation and demyelination in the hippocampus by improving the gut environment and ameliorating fluorine-induced memory dysfunction.

Abstract
The surge of obesity across generations has become an increasingly relevant issue, with consequences for associated comorbidities in offspring. Data from longitudinal birth cohort studies support an association between maternal obesity and offspring nonalcoholic fatty liver disease (NAFLD), suggesting that perinatal obesity or obesogenic diet exposure reprograms offspring liver and increases NAFLD susceptibility. In preclinical models, offspring exposed to maternal obesogenic diet have increased hepatic steatosis after diet-induced obesity; however, the implications for later NAFLD development and progression are still unclear. Although some models show increased NAFLD incidence and progression in offspring, development of nonalcoholic steatohepatitis with fibrosis may be model dependent. Multigenerational programming of NAFLD phenotypes occurs after maternal obesogenic diet exposure; however, the mechanisms for such programming remain poorly understood. Likewise, emerging data on the role of paternal obesity in offspring NAFLD development reveal incomplete mechanisms. This review will explore the impact of parental obesity and obesogenic diet exposure on offspring NAFLD and areas for further investigation, including the impact of parental diet on disease progression, and consider potential interventions in preclinical models.

Abstract
Simple Summary Our novel findings suggest that excessive backfat thickness of sows at days 109 of gestation exacerbates the metabolic disorder of perinatal sows, reduces the number and litter weight of piglets born alive, and adversely affects the intestinal health of sows and their offspring piglets. Moreover, the current study also provides an important theoretical reference for strengthening the control of body condition in sows during reproductive cycle. Abstract This study explored the effect of obesity of sows in late pregnancy on metabolic status of perinatal sows and performance, intestinal health, and immune system of offspring piglets. Sixty multiparous Landrance × Large White sows were selected in this study. Sows were divided into two groups according to backfat thickness (normal backfat thickness group, =17 mm; excessive backfat thickness group, ≥21 mm) at days 109 of gestation. The excessive backfat thickness of sows during late pregnancy decreased the total number and litter weight of piglets born alive. Compared with normal backfat thickness sows, the excessive backfat thickness sows had increased levels of plasma glucose, IL-6, and TNF-α and homeostasis model assessment insulin resistance values. The excessive backfat thickness also reduced total superoxide dismutase but increased thiobarbituric acid reactive substances in plasma of perinatal sows. Additionally, the fecal levels of TNF-α were increased but those of IL-10 were decreased in piglets from excessive backfat thickness sow. These findings indicate that the obesity of sows during late pregnancy aggravates the metabolic disorder of perinatal sows, reduces the number of piglets born alive, and adversely affects the intestinal health of sows and their offspring piglets.

Abstract
Epidemiological data reveal an association between obesity and inflammatory bowel disease (IBD). Furthermore, animal models demonstrate that maternal high-fat diet (HFD) and maternal obesity increase susceptibility to IBD in offspring. Here we report that excess calorie intake by neonatal mice, as a consequence of maternal HFD, forced feeding of neonates or low litter competition, leads to an increase during weaning in intestinal permeability, expression of pro-inflammatory cytokines and hydrogen sulfide production by the microbiota. These intestinal changes engage in mutual positive feedback that imprints increased susceptibility to colitis in adults. The pathological imprinting is prevented by the neutralization of IFN-γ and TNF-α or the production of hydrogen sulfide, or by normalization of intestinal permeability during weaning. We propose that excess calorie intake by neonates leads to multiple causally linked perturbations in the intestine that imprint the individual with long-term susceptibility to IBD.

Abstract
The combination of Puerariae Lobatae Radix (PLR) and Chuanxiong Rhizoma (CXR) is commonly used to treat cerebrovascular diseases. This work aimed to clarify the mechanisms of their action in treating cerebral ischemic stroke from the perspective of gut microecology. The PLR and CXR combination effectively improved the neurological function, reduced the cerebral infarction and relieved the complications of cerebral ischemic stroke, including dyslipidemia, increased blood viscosity and thrombotic risk. Cerebral ischemic stroke triggered gut microbial disturbances by enriching pathogens and opportunistic microorganisms, including Bacteroides, Escherichia_Shigella, Haemophilus, Eubacterium_nodatum_group, Collinsella, Enterococcus, Proteus, Alistipes, Klebsiella, Shuttleworthia and Faecalibacterium. Cerebral ischemic stroke also increased the intestinal permeability, disrupted the gut barrier and caused intestinal microbial translocation. Occludin, claudin-5 and ZO-1 levels in the brain-gut barriers showed a high positive correlation. However, the combination remodeled the gut microecology by modulating endogenous bacteria whose effects may mitigate cerebral damage, such as Alloprevotella, Ruminococcaceae, Oscillospira, Lachnospiraceae_NK4B4_group, Akkermansia and Megasphaera, protected the brain-gut barriers by increasing claudin-5 and ZO-1 levels; and weakened the gut microbiota translocation by decreasing diamine oxidase, lipopolysaccharide and d-lactate. Although nimodipine effectively reduced the cerebral infarction, it did not relieve the gut microbiota dysbiosis and instead aggravated the gut barrier disruption and microbiota translocation. In conclusion, cerebral ischemic stroke caused gut microbiota dysbiosis, increased intestinal permeability, disrupted the gut barrier and triggered gut microbiota translocation. The PLR and CXR combination was an effective treatment for cerebral ischemic stroke that relieved the gut microbiota dysbiosis and brain-gut barriers disruption.

Front Immunol 2018; 9:2608. [PMID: 30483266 PMCID: PMC6243010 DOI: 10.3389/fimmu.2018.02608] [Citation(s) in RCA: 77] [Impact Index Per Article: 12.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2018] [Accepted: 10/23/2018] [Indexed: 12/11/2022] Open
Abstract
Background: Accumulating evidence shows that high fat diet is closely associated with inflammatory bowel disease. However, the effects and underlying mechanisms of maternal high fat diet (MHFD) on the susceptibility of offspring to colitis in adulthood lacks confirmation. Methods: C57BL/6 pregnant mice were given either a high fat (60 E% fat, MHFD group) or control diet [10 E% fat, maternal control diet (MCD) group] during gestation and lactation. The intestinal development, mucosal barrier function, microbiota, and mucosal inflammation of 3-week old offspring were assessed. After weaning all mice were fed a control diet until 8 weeks of age when the microbiota was analyzed. Offspring were also treated with 2% DSS solution for 5 days and the severity of colitis was assessed. Results: The offspring in MHFD group were significantly heavier than those in MCD group only at 2–4 weeks of age, while no differences were found in the body weight between two groups at other measured time points. Compared with MCD group, MHFD significantly inhibited intestinal development and disrupted barrier function in 3-week old offspring. Although H&E staining showed no obvious microscopic inflammation in both groups of 3-week old offspring, increased production of inflammatory cytokines indicated low-grade inflammation was induced in MHFD group. Moreover, fecal analysis of the 3-week old offspring indicated that the microbiota compositions and diversity were significantly changed in MHFD group. Interestingly after 5 weeks consumption of control diet in both groups, the microbiota composition of offspring in MHFD group was still different from that in MCD group, although the bacterial diversity was partly recovered at 8 weeks of age. Finally, after DSS treatment in 8-week old offspring, MHFD significantly exacerbated the severity of colitis and increased the production of proinflammatory cytokine. Conclusions: Our data reveal that MHFD in early life can inhibit intestinal development, induce dysbiosis and low-grade inflammation and lead to the disruption of intestinal mucosal barrier in offspring, and enhance DSS-induced colitis in adulthood.

Abstract
Trichloroethylene (TCE) is a widespread environmental pollutant associated with immunotoxicity and autoimmune disease. Previous studies showed that mice exposed from gestation through early life demonstrated CD4+ T cell alterations and autoimmune hepatitis. Determining the role of one environmental risk factor for any disease is complicated by the presence of other stressors. Based on its known effects, we hypothesized that developmental overnutrition in the form of a moderately high-fat diet (HFD) consisting of 40% kcal fat would exacerbate the immunotoxicity and autoimmune-promoting effects of low-level (<10 μg/kg/day) TCE in autoimmune-prone MRL+/+ mice over either stressor alone. When female offspring were evaluated at 27 weeks of age we found that a continuous exposure beginning at 4 weeks preconception in the dams until 10 weeks of age in offspring that TCE and HFD promoted unique effects that were often antagonistic. For a number of adiposity endpoints, TCE significantly reversed the expected effects of HFD on expression of genes involved in fatty acid synthesis/insulin resistance, as well as mean pathology scores of steatosis. Although none of the animals developed pathological signs of autoimmune hepatitis, the mice generated unique patterns of antiliver antibodies detected by western blotting attributable to TCE exposure. A majority of cytokines in liver, gut, and splenic CD4+ T cells were significantly altered by TCE, but not HFD. Levels of bacterial populations in the intestinal ileum were also altered by TCE exposure rather than HFD. Thus, in contrast to our expectations this coexposure did not promote synergistic effects.

Abstract
The concordance rate for developing autoimmune disease in identical twins is around 50% demonstrating that gene and environmental interactions contribute to disease etiology. The environmental contribution to autoimmune disease is a wide-ranging concept including exposure to immunotoxic environmental chemicals. Because the immune system is immature during development suggests that adult-onset autoimmunity may originate when the immune system is particularly sensitive. Among the pollutants most closely associated with inflammation and/or autoimmunity include Bisphenol-A, mercury, TCDD, and trichloroethylene. These toxicants have been shown to impart epigenetic changes (e.g., DNA methylation) that may alter immune function and promote autoreactivity. Here we review these autoimmune-promoting toxicants and their relation to immune cell epigenetics both in terms of adult and developmental exposure.

Abstract
Inflammatory responses elicited by LRR and PYD domains-containing protein 3 (NLRP3) inflammasome is induced by a wide variety of stress signals including infectious agents and cellular disorders. E. coli O157:H7 causes serious gastrointestinal diseases that results in severe inflammation and oxidative stress, causing host cell damage. In this study, we found that E. coli O157:H7 infection induced NLRP3 assembly, caspase-1 activation and interleukin (IL)-1β and IL-18 release in Caco-2 cells. Infection also resulted in mitochondrial dysfunction with disrupted mitochondrial potential and mitochondrial complex-I activity, as well as the cytosolic release of cytochrome c and altered mitochondrial respiratory chain. The damage of mitochondria led to increased production of reactive oxygen species (ROS) and cytosolic release of mitochondrial DNA. Moreover, ROS was required for E. coli O157:H7 induced NLRP3 assembly as inhibiting mitochondrial ROS release by ROS scavengers Mito-TEMPO and N-acetylcysteine abrogated NLRP3 inflammasome activation in Caco-2 cells in response to E. coli O157:H7. Quercetin, one of the most important flavonoids in plant origin foods, had a protective role in inhibiting NLRP3 activation upon E. coli O157:H7 infection by protecting mitochondrial integrity and inhibiting mitochondrial ROS release. In addition, E. coli O157:H7 infection inhibited the host autophagy while quercetin treatment augmented autophagy activation, which further blocked ROS generation and IL-1β and IL-18 release. In summary, E. coli O157:H7 infection induced mitochondrial ROS release and NLRP3 assembly in host cells, while quercetin exerted a preventive role in host cells upon E. coli O157:H7 infection partially due to prevention of ROS production and activation of autophagy.

Abstract
Because human energy metabolism evolved to favor adiposity over leanness, the availability of palatable, easily attainable, and calorically dense foods has led to unprecedented levels of obesity and its associated metabolic co-morbidities that appear resistant to traditional lifestyle interventions. However, recent progress identifying the molecular signaling pathways through which the brain and the gastrointestinal system communicate to govern energy homeostasis, combined with emerging insights on the molecular mechanisms underlying successful bariatric surgery, gives reason to be optimistic that novel precision medicines that mimic, enhance, and/or modulate gut-brain signaling can have unprecedented potential for stopping the obesity and type 2 diabetes pandemics.

Abstract
OBJECTIVE Maternal high-fat diet (HFD) may alter the offspring intestinal immune system, thereby enhancing susceptibility toward inflammatory bowel disease. The objective of the current study was to investigate the impact of maternal HFD on offspring intestinal health using a mouse model of dextran sulfate sodium (DSS)-induced colitis. METHODS Dams were provided with either HFD (60%) or control diet. After weaning, female offspring from both groups were kept on 45% HFD. At 14 weeks of age, offspring were subjected to 2.5% DSS in drinking water for 5 days, followed by 5 days of recovery. RESULTS Offspring from maternal HFD had higher body weight gain before DSS induction and had higher liver and fat weights with increased adipocyte size at necropsy. When subjected to DSS treatment, HFD offspring had accelerated body weight loss and exaggerated disease activity index. HFD offspring had an elevated histopathological score and interleukin (IL)-1β, IL-6, and IL-17 expression with upregulated NF-κB signaling. Maternal HFD resulted in enhanced neutrophil infiltration associated with elevated expression of monocyte chemoattractant protein-1. Furthermore, maternal HFD suppressed AMP-activated protein kinase activity and decreased sirtuin 1 and p53 protein contents in offspring gut. CONCLUSIONS Maternal HFD consumption predisposes offspring to a higher susceptibility to develop inflammatory bowel disease.

Abstract
Background and aims The impairment of intestinal epithelial barrier is the main etiologic factor of inflammatory bowel disease. The proper intestinal epithelial proliferation and differentiation is crucial for maintaining intestinal integrity. Metformin is a common anti-diabetic drug. The objective is to evaluate the protective effects of metformin on ileal epithelial barrier integrity using interleukin-10 deficient (IL10KO) mice. Methods Wild-type and IL10KO mice were fed with/without metformin for 6 weeks and then ileum was collected for analyses. The mediatory role of AMP-activated protein kinase (AMPK) was further examined by gain and loss of function study in vitro. Results Compared to wild-type mice, IL10KO mice had increased proliferation, reduced goblet cell and Paneth cell lineage differentiation in the ileum tissue, which was accompanied with increased crypt expansion. Metformin supplementation mitigated intestinal cell proliferation, restored villus/crypt ratio, increased goblet cell and Paneth cell differentiation and improved barrier function. In addition, metformin supplementation in IL10KO mice suppressed macrophage pro-inflammatory activity as indicated by reduced M1 macrophage abundance and decreased pro-inflammatory cytokine IL-1β, TNF-α and IFN-γ expressions. As a target of metformin, AMPK phosphorylation was enhanced in mice treated with metformin, regardless of mouse genotypes. In correlation, the mRNA level of differentiation regulator including bmp4, bmpr2 and math1 were also increased in IL10KO mice supplemented with metformin, which likely explains the enhanced epithelial differentiation in IL10KO mice with metformin. Consistently, in Caco-2 cells, metformin promoted claudin-3 and E-cadherin assembly and mitigated TNF-α-induced fragmentation of tight junction proteins. Gain and loss of function assay also demonstrated AMPK was correlated with epithelial differentiation and proliferation. Conclusions Metformin supplementation promotes secretory cell lineage differentiation, suppresses inflammation and improves epithelial barrier function in IL10KO mice likely through activation of AMPK, showing its beneficial effects on gut epithelial.

Abstract
The incidence and prevalence of inflammatory bowel disease (IBD) continues to rise with time, signifying its emergence as a global disease. Clinical onset of IBD, comprising Crohn's disease and ulcerative colitis, typically occurs before or at peak reproductive age. Although active disease in female patients is associated with reduced fertility and adverse obstetric outcomes in pregnancy, the molecular mechanisms underlying this altered reproductive course, and its impact on IBD transmission to offspring, remain poorly understood. Clinical and experimental studies have now begun to elucidate the hormonal, environmental, and microbial factors that modulate immune-reproductive cross talk in IBD and define their impact on maternal health, fetal development, and heritability of disease risk. Evolving insight into maternal-fetal imprinting in IBD has important implications for patient counseling and disease management during pregnancy and may help predict clinical outcomes for both mother and child.

Abstract
Goji berry (Lycium barbarum) exerts immune modulation and suppresses inflammation in vitro and in vivo. We hypothesized that Goji berry had beneficial effects on dextran sulfate sodium (DSS)-induced colitis in C57BL/6 mice through suppressing inflammation. Six-week-old male C57BL/6 mice were supplemented with a standard AIN-93G diet with or without 1% (w/w) Goji berry for 4 weeks. Then, colitis was induced by supplementing 3% DSS in drinking water for 7 days, followed by 7 days of remission period to mimic ulcerative colitis symptoms. Goji berry supplementation ameliorated DSS-induced body weight loss, diminished diarrhea and gross bleeding, and resulted in a significantly decreased disease activity index, as well as DSS-associated colon shortening. Moreover, 30% mortality rate caused by DSS-induced colitis was avoided because of Goji berry supplementation. Histologically, Goji berry ameliorated colonic edema, mucosal damage and neutrophil infiltration into colonic intestinal tissue in response to DSS challenge, which was associated with decreased expression of chemokine (C-X-C motif) ligand 1 and monocyte chemoattractant protein-1, as well as inflammatory mediators interleukin-6 and cyclooxygenase-2. In conclusion, Goji supplementation confers protective effects against DSS-induced colitis, which is associated with decreased neutrophil infiltration and suppressed inflammation. Thus, dietary Goji is likely beneficial to inflammatory bowel disease patients as a complementary therapeutic strategy.

Abstract
Background The objective of this study was to investigate the effects of maternal high fat intake on intestinal development and transcriptional profile. Methods Eight gilts with similar age and body weight were randomly allocated into 2 groups receiving the control and high fat diets (HF diet) from d 30 to 90 of gestation, with 4 gilts each group and one gilt each pen. At d 90 of gestation, two fetuses each gilt were removed by cesarean section. Intestinal samples were collected for analysis of morphology, enzyme activities and transcriptional profile. Results The results showed that feeding HF diet markedly increased the fetal weight and lactase activity, also tended to increase intestinal morphology. Porcine Oligo Microarray analysis indicated that feeding HF diet inhibited 64 % of genes (39 genes down-regulated while 22 genes up-regulated),which were related to immune response, cancer and metabolism, also markedly modified 33 signal pathways such as antigen processing and presentation, intestinal immune network for IgA production, Jak-STAT and TGF-ß signaling transductions, pathways in colorectal cancer and glycerolipid metabolism. Conclusion Collectively, it could be concluded that maternal high fat intake was able to increase fetal weight and lactase activity, however, it altered the intestinal immune response, signal transduction and metabolism.

Abstract
Increasing evidence, both functional and morphological, supports the concept of increased intestinal permeability as an intrinsic characteristic of type 1 diabetes (T1D) in both humans and animal models of the disease. Often referred to as a 'leaky gut', its mechanistic impact on the pathogenesis of T1D remains unclear. Hypotheses that this defect influences immune responses against antigens (both self and non-self) predominate, yet others argue hyperglycemia and insulitis may contribute to increased gut permeability in T1D. To address these complicated issues, we herein review the many conceptual role(s) for a leaky gut in the pathogenesis of T1D and suggest ways that if true, therapeutic interventions aimed at the gut-pancreas axis may prove promising for future therapeutic interventions.

Maternal High-fat Diet Accelerates Development of Crohn's Disease-like Ileitis in TNFΔARE/WT Offspring. Inflamm Bowel Dis 2015; 21:2016-25.

Abstract
BACKGROUND Maternal high-fat diet (HFD) and obesity increases the risk of the offspring to develop inflammatory processes in various organs including the gut. We hypothesized that maternal diet-induced obesity programs the fetal gut towards inflammation in a mouse model of genetically-driven Crohn's disease (CD)-like ileitis. METHODS TNF(WT/WT) and TNF(ΔARE/WT) dams were fed an experimental control diet (CTRLD; 13 kJ% fat) or HFD (48 kJ%). Offspring mice were fed CTRLD or HFD at 4 weeks of age. Metabolic characteristics and severity of CD-like ileitis was assessed in 8- and 12-week old WT and ARE offspring measuring tissue histopathology and markers of inflammation in the distal ileum as well as plasma cytokine and LPS levels. To study prenatal effects, we laser microdissected fetal intestinal epithelial cells at 17.5 days postconception and performed microarray-based global gene expression analysis. RESULTS Maternal HFD significantly accelerated the severity of CD-like ileitis in HFD-fed ARE mice at early life stages associated with increased mucosal neutrophil infiltration, Il12p40 expression, and portal vein LPS levels. In contrast to WT mice, metabolic characteristics of ARE offspring were not affected by maternal HFD. Gene expression patterns in fetal intestinal epithelial cells of ARE mice remained largely unchanged under conditions of maternal diet-induced obesity suggesting that the positive association of intestinal inflammation, portal vein endotoxemia, and plasma TNF levels is independent of prenatal conditioning of the gut epithelium. CONCLUSIONS Maternal HFD promotes the early onset of severe CD-like ileitis in genetically susceptible offspring independent of metabolic alterations.

Abstract
Studies have demonstrated that epigenetic changes such as DNA methylation, histone modification, and chromatin remodeling are linked to an increased inflammatory response as well as increased risk of chronic disease development. A few studies have begun to investigate whether dietary nutrients play a beneficial role by modifying or reversing epigenetically induced inflammation. Results of these studies show that nutrients modify epigenetic pathways. However, little is known about how nutrients modulate inflammation by regulating immune cell function and/or immune cell differentiation via epigenetic pathways. This overview will provide information about the current understanding of the role of nutrients in the epigenetic control mechanisms of immune function.

Abstract
Obesity in pregnant women is a growing public health concern that negatively affects fetal development and has long-term impacts on offspring health. The placenta plays an essential role in nutrient transport to the fetus and supports fetal growth and development. Maternal obesity (MO) induces an exacerbated proinflammatory milieu in the placenta providing an inflammatory environment for fetuses. The gut is one of the largest immune organs and mainly develops during the fetal stage. Maternal obesity and the corresponding inflammatory uteroplacental environment affect gut development, incurring inflammatory responses in the fetal intestine that further prime or program the offspring gut to enhance inflammation and impair intestinal barrier integrity. This review summarizes the impact of MO on inflammatory responses in placenta and fetal intestine and the long-term effects on offspring intestinal health. Because "leaky gut" is one of the main etiological factors for a number of common diseases, including inflammatory bowel diseases, type I diabetes, and related autoimmune diseases, the adverse effect of MO on the overall health of progeny is further discussed.
