The dynamics of molecular, immune and physiological features of the host and the gut microbiome, and their interactions before and after onset of laying in two hen strains.

Abstract
Aggregation of data, including deep sequencing of mRNA and miRNA data in jejunum mucosa, abundance of immune cells, metabolites, or hormones in blood, composition of microbiota in digesta and duodenal mucosa, and production traits collected along the lifespan, provides a comprehensive picture of lifelong adaptation processes. Here, respective data from two laying hen strains (Lohmann Brown-Classic (LB) and Lohmann LSL-Classic (LSL) collected at 10, 16, 24, 30, and 60 wk of age were analyzed. Data integration revealed strain- and stage-specific biosignatures, including elements indicative of molecular pathways discriminating the strains. Although the strains performed the same, they differed in the activity of immunological and metabolic functions and pathways and showed specific gut-microbiota-interactions in different production periods. The study shows that both strains employ different strategies to acquire and maintain their capabilities under high performance conditions, especially during the transition phase. Furthermore, the study demonstrates the capacity of such integrative analyses to elucidate molecular pathways that reflect functional biodiversity. The bioinformatic reduction of the multidimensional data provides good guidance for further manual review of the data.

A defective interleukin-17 receptor A1 causes weight loss and intestinal metabolism-related gene downregulation in Japanese medaka, Oryzias latipes. Sci Rep 2021; 11:12099. [PMID: 34103614 PMCID: PMC8187396 DOI: 10.1038/s41598-021-91534-3] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2020] [Accepted: 05/27/2021] [Indexed: 02/08/2023] Open
Abstract
In the intestine, the host must be able to control the gut microbiota and efficiently absorb transiently supplied metabolites, at the risk of enormous infection. In mammals, the inflammatory cytokine interleukin (IL)-17A/F is one of the key mediators in the intestinal immune system. However, many functions of IL-17 in vertebrate intestines remain unclarified. In this study, we established a gene-knockout (KO) model of IL-17 receptor A1 (IL-17RA1, an IL-17A/F receptor) in Japanese medaka (Oryzias latipes) using genome editing technique, and the phenotypes were compared to wild type (WT) based on transcriptome analyses. Upon hatching, homozygous IL-17RA1-KO medaka mutants showed no significant morphological abnormality. However, after 4 months, significant weight decreases and reduced survival rates were observed in IL-17RA1-KO medaka. Comparison of gene-expression patterns in WT and IL-17RA1-KO medaka revealed that various metabolism- and immune-related genes were significantly down-regulated in IL-17RA1-KO medaka intestine, particularly genes related to mevalonate metabolism (mvda, acat2, hmgcs1, and hmgcra) and genes related to IL-17 signaling (such as il17c, il17a/f1, and rorc) were found to be decreased. Conversely, expression of genes related to cardiovascular system development, including fli1a, sox7, and notch1b in the anterior intestine, and that of genes related to oxidation-reduction processes including ugp2a, aoc1, and nos1 in posterior intestine was up-regulated in IL-17RA1-KO medaka. These findings show that IL-17RA regulated immune- and various metabolism-related genes in the intestine for maintaining the health of Japanese medaka.

Abstract
Neonates and infants are particularly susceptible to infections, for which outcomes tend to be severe. Vaccination is a key strategy for preventing infectious diseases, but the protective immunity achieved through vaccination typically is weaker in infants than in healthy adults. One possible explanation for the poor acquisition of vaccine-induced immunity in infants is that their innate immune response, represented by toll-like receptors, is immature. The current system for developing pediatric vaccines relies on the confirmation of their safety and effectiveness in studies involving the use of mature animals or adult humans. However, creating vaccines for neonates and infants requires an understanding of their uniquely immature innate immunity. Here we review current knowledge regarding the innate immune system of neonates and infants and challenges in developing vaccine adjuvants for those children through analyses of cord blood.

Animals (Basel) 2019; 9:ani9060309. [PMID: 31159303 PMCID: PMC6617192 DOI: 10.3390/ani9060309] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2019] [Revised: 05/21/2019] [Accepted: 05/29/2019] [Indexed: 12/31/2022] Open
Abstract
Simple Summary Clinical mastitis is one of the most common diseases in sheep and is of major economic concern due to treatment costs, inadequate lamb growth and premature eliminate of ewes. To preliminarily explore possible regulatory roles of proteins involved in the host-pathogen interactions during intramammary infection triggered by this disease in meat sheep, mammary tissues were harvested from sheep with healthy and clinical mastitis caused by natural infection, and the differentially expressed proteins were identified in an infected group when compared to a healthy group, using comparative proteomics based on two-dimensional electrophoresis. Further enrichment analyses indicated that most of the differentially expressed proteins mainly engaged in regulating immune responses and metabolisms. These findings offer candidate proteins for further studies on molecular mechanisms of host defense response and metabolism in sheep cases. Abstract Clinical mastitis is still an intractable problem for sheep breeding. The natural immunologic mechanisms of the mammary gland against infections are not yet understood. For a better understanding of the disease-associated proteins during clinical mastitis in meat sheep, we performed two-dimensional electrophoresis (2-DE)-based comparative proteomic analyses of mammary tissues, including from healthy mammary tissues (HMTs) and from mammary tissues with clinical mastitis (CMMTs). The 2-DE results showed that a total of 10 up-regulated and 16 down-regulated proteins were identified in CMMTs when compared to HMTs. Of these, Gene Ontology (GO) and Kyoto Encyclopaedia of Genes and Genomes (KEGG) enrichment analyses revealed that most proteins were associated with immune responses or metabolisms. The results of qRT-PCR and Western blot for randomly selected four differentially expressed proteins (DEPs) including superoxide dismutase [Mn] (SOD2), annexin A2 (ANAX2), keratin 10 (KRT10) and endoplasmic reticulum resident protein 29 (ERP29) showed that their expression trends were consistent with 2-DE results except ANXA2 mRNA levels. This is an initial report describing the 2-DE-based proteomics study of the meat sheep mammary gland with clinical mastitis caused by natural infection, which provides additional insight into the immune and metabolic mechanisms during sheep mastitis.

Abstract
Despite its direct exposure to huge amounts of microorganisms and foreign and dietary antigens, the gut mucosa maintains intestinal homeostasis by utilizing the mucosal immune system. The gut mucosal immune system protects the host from the invasion of infectious pathogens and eliminates harmful non-self antigens, but it allows the cohabitation of commensal bacteria in the gut and the entry of dietary non-self antigens into the body via the mucosal surface. These physiological and immunological activities are regulated by the ingenious gut mucosal immune network, comprising such features as gut-associated lymphoid tissue, mucosal immune cells, cytokines, chemokines, antimicrobial peptides, secretory IgA, and commensal bacteria. The gut mucosal immune network keeps a fine tuned balance between active immunity (against pathogens and harmful non-self antigens) and immune tolerance (to commensal microbiota and dietary antigens), thus maintaining intestinal healthy homeostasis. Disruption of gut homeostasis results in persistent or severe gastrointestinal infection, inflammatory bowel disease, or allergic inflammation. In this review, we comprehensively introduce current knowledge of the gut mucosal immune system, focusing on its interaction with allergic inflammation.

Gene expression profiles in peripheral blood mononuclear cells correlate with salience network activity in chronic visceral pain: A pilot study. Neurogastroenterol Motil 2017; 29:10.1111/nmo.13027. [PMID: 28191693 PMCID: PMC5503466 DOI: 10.1111/nmo.13027] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/20/2016] [Accepted: 12/12/2016] [Indexed: 12/17/2022]
Abstract
BACKGROUND Distinct gene expression profiles in peripheral blood mononuclear cells (PBMCs) consistent with increased sympathetic nervous system activity have been described in different populations under chronic stress. Neuroinflammatory brain changes, possibly related to the migration of primed monocytes to the brain, have been implicated in the pathophysiology of chronic pain. Irritable bowel syndrome (IBS) is a stress-sensitive gastrointestinal disorder associated with altered brain-gut interactions and increased sympathetic/vagal tone and anxiety. Reports about immune alterations in IBS are conflicting. This pilot study aimed to test how PBMC gene expression inflammatory profiles are correlated with altered brain signatures in the salience system. METHODS Sixteen IBS and 16 healthy controls (HCs) completed resting state MRI scans. Gene expression profiles in PBMCs were assessed using human transcriptome array-2. Bioinformatic analyses determined differential expression of PBMCs between IBS and HCs. Partial least squares, a multivariate analysis technique, was used to identify disease correlations between PBMC gene expression profiles and functional activity in the brain's salience network. KEY RESULTS Regions of the salience network, including the mid cingulate cortex, and mid and superior temporal gyrus were positively correlated with several pro-inflammatory genes (interleukin 6, APOL2) in IBS, but negatively correlated with several anti-inflammatory genes (KRT8, APOA4) in HCs. CONCLUSIONS & INFERENCES Based on rodent studies, one may speculate that chronically activated stress signaling pathways in IBS maintain a pro-inflammatory state in the periphery. Alternatively, primed monocytes may migrate to the brain during stress, inducing regional neuroinflammatory changes in salience regions involved in the modulation of visceral sensitivity.
