Abstract
INTRODUCTION An association between functional dyspepsia (FD) and wheat-containing foods has been reported in observational studies; however, an adaptive response has not been demonstrated. We examined whether antigens present in wheat could provoke a response from FD duodenal lymphocytes. METHODS Lamina propria mononuclear cells (LPMCs) were isolated from duodenal biopsies from 50 patients with FD and 23 controls. LPMCs were exposed to gluten (0.2 mg/mL) or gliadin (0.2 mg/mL) for 24 hours. Flow cytometry was performed to phenotype lymphocytes. Quantitative PCR was used to measure the expression of gliadin-associated T-cell receptor alpha variant ( TRAV ) 26-2. RESULTS In response to gliadin (but not gluten) stimulation, the effector Th2-like population was increased in FD LPMCs compared with that in controls and unstimulated FD LPMCs. Duodenal gene expression of TRAV26- 2 was decreased in patients with FD compared with that in controls. We identified a positive association between gene expression of this T-cell receptor variant and LPMC effector Th17-like cell populations in patients with FD, but not controls after exposure to gluten, but not gliadin. DISCUSSION Our findings suggest that gliadin exposure provokes a duodenal effector Th2-like response in patients with FD, supporting the notion that food antigens drive responses in some patients. Furthermore, these findings suggest that altered lymphocyte responses to wheat proteins play a role in FD pathogenesis.

Abstract
Background Functional dyspepsia is characterised by chronic symptoms of post-prandial distress or epigastric pain not associated with defined structural pathology. Increased peripheral gut-homing T cells have been previously identified in patients. To date, it is unknown if these T cells were antigen-experienced, or if a specific phenotype was associated with FD. Objective This study aimed to characterise T cell populations in the blood and duodenal mucosa of FD patients that may be implicated in disease pathophysiology. Methods We identified duodenal T cell populations from 23 controls and 49 Rome III FD patients by flow cytometry using a surface marker antibody panel. We also analysed T cell populations in peripheral blood from 37 controls and 61 patients. Where available, we examined the number of duodenal eosinophils in patients and controls. Results There was a shift in the duodenal T helper cell balance in FD patients compared to controls. For example, patients had increased duodenal mucosal Th2 populations in the effector (13.03 ± 16.11, 19.84 ± 15.51, p=0.038), central memory (23.75 ± 18.97, 37.52 ± 17.51, p=0.007) and effector memory (9.80±10.50 vs 20.53±14.15, p=0.001) populations. Th17 populations were also increased in the effector (31.74±24.73 vs 45.57±23.75, p=0.03) and effector memory (11.95±8.42 vs 18.44±15.63, p=0.027) subsets. Peripheral T cell populations were unchanged between FD and control. Conclusion Our findings identify an association between lymphocyte populations and FD, specifically a Th2 and Th17 signature in the duodenal mucosa. The presence of effector and memory cells suggest that the microinflammation in FD is antigen driven.

Abstract
Intestinal epithelia are critical for maintaining gastrointestinal homeostasis. Epithelial barrier injury, causing inflammation and vascular damage, results in inflammatory hypoxia, and thus, healing occurs in an oxygen-restricted environment. The transcription factor hypoxia-inducible factor (HIF)-1 regulates genes important for cell survival and repair, including the cell adhesion protein β1-integrin. Integrins function as αβ-dimers, and α-integrin-matrix binding is critical for cell migration. We hypothesized that HIF-1 stabilization accelerates epithelial migration through integrin-dependent pathways. We aimed to examine functional and posttranslational activity of α-integrins during HIF-1-mediated intestinal epithelial healing. Wound healing was assessed in T84 monolayers over 24 h with/without prolyl-hydroxylase inhibitor (PHDi) (GB-004), which stabilizes HIF-1. Gene and protein expression were measured by RT-PCR and immunoblot, and α-integrin localization was assessed by immunofluorescence. α-integrin function was assessed by antibody-mediated blockade, and integrin α6 regulation was determined by HIF-1α chromatin immunoprecipitation. Models of mucosal wounding and 2,4,6-trinitrobenzenesulfonic acid (TNBS)-induced colitis were used to examine integrin expression and localization in vivo. PHDi treatment accelerated wound closure and migration within 12 h, associated with increased integrin α2 and α6 protein, but not α3. Functional blockade of integrins α2 and α6 inhibited PHDi-mediated accelerated wound closure. HIF-1 bound directly to the integrin α6 promoter. PHDi treatment accelerated mucosal healing, which was associated with increased α6 immunohistochemical staining in wound-associated epithelium and wound-adjacent tissue. PHDi treatment increased α6 protein levels in colonocytes of TNBS mice and induced α6 staining in regenerating crypts and reepithelialized inflammatory lesions. Together, these data demonstrate a role for HIF-1 in regulating both integrin α2 and α6 responses during intestinal epithelial healing.NEW & NOTEWORTHY HIF-1 plays an important role in epithelial restitution, selectively inducing integrins α6 and α2 to promote migration and proliferation, respectively. HIF-stabilizing prolyl-hydroxylase inhibitors accelerate intestinal mucosal healing by inducing epithelial integrin expression.

Abstract
*MDD is the predominant cause of “Years of life lived with disability” and “Years of life lost because of premature death” as a consequence of the disorder per se, comorbidities (cardiovascular, diabetes) and the high suicide rate. The problem is increasing due to higher depression frequency with age and growing life-longevity. One third of patients do not respond adequately to conventional therapies and “more of the same” drugs will not solve the problem. Consequently, there exists a crucial need to develop treatments with different modes of action. *Neuropeptide Y (NPY) and neuropeptide S (NPS) have been mapped in brain of MDD and PTSD rodent models. NPY is reduced in genetic and environmental depression models and in PTSD and can be reversed by antidepressants. These findings are parallel to the decreased NPY in humans diagnosed with MDD and PTSD. *NPS found in locus caeruleus regulates anxiety and stress–related behaviors and intranasal administration is anxiolytic in rat. The intranasal effects in humans are being explored. *Based on known biology and our findings, we hypothesized that NPY could be a target for MDD and PTSD, the reasoning being analogous to insulin treatment in insulin deficient diabetes, and conducted - the first ever - double blind, placebo controlled trials of insufflated NPY in MDD and PTSD (Sayed et al 2018, Mathé et al 2020). In conclusion, intranasal NPY is opening a promising new avenue for efficient, fast acting treatment of MDD and PTSD.

Abstract
Liver inflammation is a common extraintestinal manifestation in inflammatory bowel disease (IBD), yet, the mechanisms driving gut-liver axis inflammation remain poorly understood. IBD leads to a breakdown in the integrity of the intestinal barrier causing an increase in portal and systemic gut-derived antigens, which challenge the liver. Here, we examined the role of platelet activating factor receptor (PAFR) in colitis-associated liver damage using dextran sulfate sodium (DSS) and anti-CD40-induced colitis models. Both DSS and anti-CD40 models exhibited liver inflammation associated with colitis. Colitis reduced global PAFR protein expression in mouse livers causing an exclusive re-localization of PAFR to the portal triad. The global decrease in liver PAFR was associated with increased sirtuin 1 while relocalized PAFR expression was limited to Kupffer cells (KCs) and co-localized with toll-like receptor 4. DSS activated the NLRP3-inflammasome and increased interleukin (IL)-1β in the liver. Antagonism of PAFR amplified the inflammasome response by increasing NLRP3, caspase-1, and IL-1β protein levels in the liver. LPS also increased NLRP3 response in human hepatocytes, however, overexpression of PAFR restored the levels of NLPR3 and caspase-1 proteins. Interestingly, KCs depletion also increased IL-1β protein in mouse liver after DSS challenge. These data suggest a protective role for PAFR-expressing KCs during colitis and that regulation of PAFR is important for gut-liver axis homeostasis.

Abstract
BACKGROUND Colorectal cancer is the third most common cancer worldwide. Almost half of those that have a potentially curative resection go on to develop metastatic disease. A recognized risk for recurrence is perioperative systemic inflammation and sepsis. Neutrophil extracellular traps have been implicated as promotors of tumor progression. We aimed to examine the evidence in the literature for an association between neutrophil extracellular traps and postoperative metastasis in colorectal cancer. MATERIALS AND METHODS Studies published between 2000 and December 2018 that examined the role of neutrophil extracellular traps in sepsis and inflammation in colorectal cancer and in relation to tumor-related outcomes were identified through a database search of Cochrane, CINAHL, and MEDLINE. Quality and bias assessment was carried out by 2 reviewers. RESULTS Of 8,940 screened and of the 30 studies included, 21 were observational, 5 were in vivo experimental, 1 was in vitro, and 3 used a combination of these approaches. CONCLUSION There is clear evidence from the literature that presence of a preoperative systemic inflammatory response predicts cancer recurrence following potentially curative resection, but the evidence for association of sepsis and progression is lacking. There is robust experimental evidence in murine models showing that neutrophil extracellular traps are present in sepsis and are associated with cancer progression. Some human observational studies corroborate the prognostic significance of neutrophil extracellular traps in progression of colorectal cancer. Further human studies are needed to translate the experimental evidence and to definitively associate sepsis and neutrophil extracellular traps with poor colorectal cancer-specific outcomes.

Abstract
Abstract
Background: Triple negative breast cancer (TNBC) is a highly metastatic and aggressive subtype of breast cancer which lacks receptors for-estrogen, progesterone and human epidermal growth factor 2. It accounts for approximately 10-20% of all breast cancer cases. It is commonly diagnosed in younger African-American women less than 40 years. There are no targeted therapies for this breast cancer subtype, therefore, chemotherapy and surgery remain the only options for treatment. However, there is a high chance of recurrence within three years of diagnosis and the majority of deaths occurs within the five years of diagnosis. High genomic aberration is a common event in this cancer where the differentially expressed genes in TNBC could be due to the variations in copy number of those genes. The dissemination of primary cancer cells to the lymphatic system represents one of the first signs of meta-static spread. In TNBC, any LN involvement is associated with worse disease-free and overall survival. Therefore, identification of copy number variations (CNVs) within LN metastases in this highly aggressive breast cancer subtype may serve as an indicator of prognosis. Objectives: The aim of the current study was to define regions of copy number gain or loss that are associated with metastasis to the lymph node in TNBC and their association with gene expression. Methods: Partek Genomic Suite was used to analyse the copy number variations in the study cohort containing 23 invasive ductal carcinoma (IDC), 12 lymph node metastasis (LNmets) and 3 normal adjacent tissues (NAT); as well as in validation cohort containing 70 IDC samples (Avery-Kiejda KA, Genom Data.2017;14:1-4).All the breast cancer samples were TNBC. The genomic segmentation algorithm was used for copy number detection. Moreover, their association with gene expression was also analysed using previous gene expression datasets (Accession No.GSE78758). Additionally, GO-enrichment and pathway analysis was performed to identify functional groups and pathways affected by copy number changes. Results: More CNV regions were amplified compared to loss in both the study and the validation cohort. The whole genome copy number profile was similar between IDC and lymph node metastases with 81% (263 in total) of amplified CNVs present in LNmets also present in matched IDCs, implying that many of the alterations in the primary tumour were carried over in metastasis. Very few genes were deleted and of those that were, only 2 were common to IDCs and LNmets. No significant CNVs were observed in NAT. Frequent amplification was mainly observed in chromosome 1q, 8q and 10p whereas the deletion in 4q, 5q and 14q was common in both IDC and metastasis samples. In total, 95 genes (66 gains and 29 losses) were only present in LNmet and not in IDCs from either the study or validation cohorts. According to GO-enrichment analysis, these LNmet associated genes were mainly enriched for DNA-binding transcription activity, cell fate specification and negative regulation of EGFR signalling pathway. Conclusion: This study has identified several regions of CNV in a well-defined TNBC cohort that could play major role in metastasis to lymph node.

Abstract
STUDY QUESTION Are any microRNAs (miRNAs) that target the placental renin-angiotensin system (RAS) in the human placenta suppressed in early gestation? SUMMARY ANSWER Overall, 21 miRNAs with predicted RAS mRNA targets were less abundant in early versus term placentae and nine were more highly expressed. WHAT IS KNOWN ALREADY Regulation of human placental RAS expression could alter placental development and therefore normal pregnancy outcome. The expression of genes encoding prorenin (REN), angiotensinogen, (pro)renin receptor, angiotensin converting enzyme 2, and the angiotensin II type 1 receptor are highest in early gestation, at a time when oxygen tension is at its lowest. Studies have shown that the human placental RAS is sensitive to oxygen, as are some miRNAs that regulate RAS mRNAs. We propose that in early pregnancy, the prevailing low O2 tension, by suppression of levels of miRNAs that target RAS mRNAs, results in increased expression of RAS mRNAs and encoded proteins. As gestation proceeds and the prevailing oxygen tension rises, abundance of these miRNAs increases, and placental RAS mRNA expression is suppressed. STUDY DESIGN, SIZE, DURATION The expression of miRNAs was compared in human placentae collected in early (10-11 weeks; n = 7) and mid-gestation (14-18 weeks; n = 8) with placenta collected at term (38-40 weeks; n = 8). Expression of placental miRNAs in women with early (29-35.1 weeks; n = 8) or late-onset pre-eclampsia (PE) (>34-weeks gestation; n = 8) and gestational age matched preterm (31.6-35.1 weeks; n = 8) and term normotensive controls were also compared. PARTICIPANTS/MATERIALS, SETTING, METHODS Agilent Human miRNA microarray v19 was used to detect up to 2006 miRNAs in four placentae from each group. Statistically different levels of expression were determined and refined using predictive modelling. Placental miRNAs predicted to target RAS mRNAs were identified in three databases. Differences detected on the array were confirmed for some miRNAs by semi-quantitative RT-PCR (qPCR, n = 7-8 for all groups). Two differentially expressed miRNAs that were known to target human renal REN mRNA (miR-181a-5p and miR-663) were transfected into human HTR-8/SVneo trophoblast cells to examine their effect on placental REN expression and prorenin levels. MAIN RESULTS AND THE ROLE OF CHANCE In early gestation placentae, 186 miRNAs were differentially expressed compared with term placentae (109 increased, 77 decreased). Thirty of the differentially expressed miRNAs were predicted to target RAS components. In mid-gestation placentae, 117 miRNAs were differentially expressed compared with term placentae (69 increased, 48 decreased). Of these, 19 had RAS mRNAs as predicted targets. Eight miRNAs that were lower in early gestation and predicted to target RAS mRNAs were confirmed by qPCR. All showed an increase during gestation and could influence the transgestational profile of the human placental RAS. Additionally, on the array, three miRNAs predicted to target RAS mRNAs (miR-892c-3p, miR-378c and miR-514b-3p) were overexpressed in placentae from women with late-onset PE (P = 3.6E-10, P = 1.8E-05, P = 5.3E-06; respectively). miR-663, which suppresses renal REN mRNA expression, was overexpressed in early-onset PE placentae as determined by qRT-PCR analysis (P = 0.014). Transfection of miR-181a-5p and miR-663 into HTR-8/SVneo trophoblast cells suppressed REN mRNA expression (P = 0.05) and prorenin protein production (P = 0.001). LARGE SCALE DATA Data can be found via GEO accession number GSE109832. LIMITATIONS, REASONS FOR CAUTION Further validation that the differentially expressed miRNAs do indeed directly target RAS mRNAs and affect placental development and function is required. This study is limited by the small sample size. Therefore independent validation in a larger cohort is required. WIDER IMPLICATIONS OF THE FINDINGS We propose that suppression of miRNAs that target the placental RAS in early gestation is partly responsible for the increase in RAS expression at this time, in order to promote placental development. Later in pregnancy, we have detected overexpression of several miRNAs in placentae from women with PE. These may prove to be biomarkers for early detection of women at risk of developing PE. Since the placenta produces at least two miRNAs that were found in the kidney to target REN mRNA, and that also target placental REN mRNA, the escape of these miRNAs into the maternal circulation in excess amounts could affect maternal renal REN mRNA production and thereby disturb maternal fluid and electrolyte homoeostasis.

Abstract
Extra-intestinal manifestations (EIM) are common in inflammatory bowel disease (IBD). One such EIM is sub-clinical pulmonary inflammation, which occurs in up to 50% of IBD patients. In animal models of colitis, pulmonary inflammation is driven by neutrophilic infiltrations, primarily in response to the systemic bacteraemia and increased bacterial load in the lungs. Platelet activating factor receptor (PAFR) plays a critical role in regulating pulmonary responses to infection in conditions, such as chronic obstructive pulmonary disease and asthma. We investigated the role of PAFR in pulmonary EIMs of IBD, using dextran sulfate sodium (DSS) and anti-CD40 murine models of colitis. Both models induced neutrophilic inflammation, with increased TNF and IL-1β levels, bacterial load and PAFR protein expression in mouse lungs. Antagonism of PAFR decreased lung neutrophilia, TNF, and IL-1β in an NLRP3 inflammasome-dependent manner. Lipopolysaccharide from phosphorylcholine (ChoP)-positive bacteria induced NLRP3 and caspase-1 proteins in human alveolar epithelial cells, however antagonism of PAFR prevented NLRP3 activation by ChoP. Amoxicillin reduced bacterial populations in the lungs and reduced NLRP3 inflammasome protein levels, but did not reduce PAFR. These data suggest a role for PAFR in microbial pattern recognition and NLRP3 inflammasome signaling in the lung.

Abstract
Human placental renin-angiotensin system (RAS) expression is highest in early gestation, at a time when placental oxygen tension is at its lowest (1-3%), and promotes placental development. Some miRNAs predicted to target RAS mRNAs are downregulated in early gestation. We tested the hypothesis that low oxygen suppresses expression of miRNAs that target placental RAS mRNAs, thus increasing concentrations of RAS mRNAs. HTR-8/SVneo cells were cultured in 1, 5 and 20% oxygen for 48 h. Differences in miRNA expression were measured on an Affymetrix miRNA microarray (n = 3/group). Those predicted to target RAS mRNAs, or that were decreased in early gestation, were confirmed by qPCR (n = 9/group). RAS protein levels were assessed by ELISAs or immuno-blotting. Microarray analysis identified four miRNAs predicted to target RAS mRNAs that were differentially expressed between 1 and 5% oxygen. Using qPCR, 15 miRNAs that target the RAS were measured in HTR-8/SVneo cells. Five miRNAs were downregulated in 1% compared with 5% oxygen. Expression of a number of RAS mRNAs (ATP6AP2, AGT, ACE and AGTR1) were increased in either, or both, 1 and 5% oxygen compared with 20% oxygen. AGT protein levels were increased in 1% oxygen compared with 5%. Further validation is needed to confirm that these miRNAs target RAS mRNAs directly and that placental development is partly regulated by oxygen-sensitive miRNAs that target RAS mRNAs. Since placental oxygen tension changes across gestation, changes in expression of these miRNAs may contribute to the transgestational changes in placental RAS expression and the resulting effects on placental development.

Abstract
The functional maturation of spermatozoa that is necessary to achieve fertilization occurs as these cells transit through the epididymis, a highly specialized region of the male reproductive tract. A defining feature of this maturation process is that it occurs in the complete absence of nuclear gene transcription or de novo, protein translation in the spermatozoa. Rather, it is driven by sequential interactions between spermatozoa and the complex external milieu in which they are bathed within lumen of the epididymal tubule. A feature of this dynamic microenvironment are epididymosomes, small membrane encapsulated vesicles that are secreted from the epididymal soma. Herein, we report comparative proteomic profiling of epididymosomes isolated from different segments of the mouse epididymis using multiplexed tandem mass tag (TMT) based quantification coupled with high resolution LC-MS/MS. A total of 1640 epididymosome proteins were identified and quantified via this proteomic method. Notably, this analysis revealed pronounced segment-to-segment variation in the encapsulated epididymosome proteome. Thus, 146 proteins were identified as being differentially accumulated between caput and corpus epididymosomes, and a further 344 were differentially accumulated between corpus and cauda epididymosomes (i.e., fold change of ≤ -1.5 or ≥ 1.5; p, < 0.05). Application of gene ontology annotation revealed a substantial portion of the epididymosome proteins mapped to the cellular component of extracellular exosome and to the biological processes of transport, oxidation-reduction, and metabolism. Additional annotation of the subset of epididymosome proteins that have not previously been identified in exosomes revealed enrichment of categories associated with the acquisition of sperm function (e.g., fertilization and binding to the zona pellucida). In tandem with our demonstration that epididymosomes are able to convey protein cargo to the head of maturing spermatozoa, these data emphasize the fundamental importance of epididymosomes as key elements of the epididymal microenvironment responsible for coordinating post-testicular sperm maturation.

Abstract
BACKGROUND Subtle histopathologic features such as eosinophilia and increased mast cells have been observed in functional gastrointestinal disorders (FGIDs), including functional dyspepsia (FD) and the irritable bowel syndrome (IBS). The mechanisms that drive recruitment of these cells to the gastrointestinal tract remain unexplained, largely due to the heterogeneity in phenotypes among patients diagnosed with such conditions. We aimed to systematically review the literature and collate the evidence for immune activation in FD and IBS, and where possible, detail the nature of activation. METHODS Seven literature databases were searched using the keywords: 'functional gastrointestinal disorder', FGID, 'functional dyspepsia', 'non-ulcer dyspepsia', 'idiopathic dyspepsia', 'irritable bowel syndrome', IBS and 'immun*'. RESULTS Fifty-one papers reporting discordant immune features met the selection criteria for this review. Changes in lymphocyte populations, including B and T lymphocyte numbers and activation status were reported in IBS and FD, in conjunction with duodenal eosinophilia in FD and increased colonic mast cells in IBS. Increases in circulating α4+β7+ gut-homing T cells appear to be linked to the pathophysiology of both FD and IBS. Studies in the area are complicated by poor phenotyping of patients into subgroups and the subtle nature of the immune activity involved in FD and IBS. CONCLUSIONS Alterations in proportions of gut-homing T lymphocytes in both FD and IBS indicate that a loss of mucosal homeostasis may drive the symptoms of FD and IBS. There is indirect evidence that Th17 responses may play a role in FGIDs, however the evidence for a Th2 immune phenotype in FD and IBS is limited. Although immune involvement is evident, large, well-characterised patient cohorts are required to elucidate the immune mechanisms driving the development of FGIDs.

Abstract
Mutation of p53 is a common feature of cancer. Breast cancer is the most common malignancy that develops in women; however, somatic mutation of p53 is rare, suggesting that p53 becomes inactivated by other mechanisms. p53 is expressed as smaller isoforms, some of which inhibit wild-type p53. There are no studies that have examined the relative expression of all isoforms in this disease. We have analysed the relative messenger RNA expression of the p53 isoforms, Δ40, Δ133, β and γ in a panel of 6 breast cancer cell lines, 148 breast cancers specimens and 31 matched normal adjacent tissues by semi-quantitative real-time reverse transcription-PCR and analysed their relationship to clinical features and outcome. We have identified several important clinical associations, particularly with Δ40p53, which was expressed at levels that were ~50-fold higher than the least expressed isoform p53γ. Δ40p53 was significantly upregulated in tumour tissue when compared with the normal breast and was significantly associated with an aggressive breast cancer subtype-triple negative. Additionally, p53β expression was significantly negatively associated with tumour size and positively associated with disease-free survival, where high levels of p53β were protective, particularly in patients with a mutation in p53, suggesting p53β may counteract the damage inflicted by mutant p53. In conclusion, the relative expression of p53 isoforms is related to clinical features of breast cancer and outcome. These results have implications for the stratification of breast cancer based on p53 function and may provide an alternate explanation for deregulated p53 signalling in breast cancer.

Abstract
1. Plants and their biologically active chemical constituents, sometimes called secondary metabolites or bioactives, present numerous opportunities for the improvement of livestock production by inclusion in the diet. 2. Many such plant derived materials have well established therapeutic values in man; however, their potential as feed additives in animal production, particularly of poultry, remains largely unexploited. 3. There is increasing evidence indicating that they can be efficient in controlling diseases, and plant bioactives may also influence production parameters such as feed efficiency and product quality. 4. It has been reported that they may even replicate some of the effects of antibiotic growth promoters, which were banned from use in Europe from 2006. 5. This review assesses the status of plant bioactives in poultry production and their mode of action on avian physiology, particularly in the digestive tract.
