Strains of mice in which certain GENES of their GENOMES have been disrupted, or "knocked-out". To produce knockouts, using RECOMBINANT DNA technology, the normal DNA sequence of the gene being studied is altered to prevent synthesis of a normal gene product. Cloned cells in which this DNA alteration is successful are then injected into mouse EMBRYOS to produce chimeric mice.

Goblet cell-specific expression mediated by the MUC2 mucin gene promoter in the intestine of transgenic mice. (1/560)

The regulation of MUC2, a major goblet cell mucin gene, was examined by constructing transgenic mice containing bases -2864 to +17 of the human MUC2 5'-flanking region fused into the 5'-untranslated region of a human growth hormone (hGH) reporter gene. Four of eight transgenic lines expressed reporter. hGH message expression was highest in the distal small intestine, with only one line expressing comparable levels in the colon. This contrasts with endogenous MUC2 expression, which is expressed at its highest levels in the colon. Immunohistochemical analysis indicated that goblet cell-specific expression of reporter begins deep in the crypts, as does endogenous MUC2 gene expression. These results indicate that the MUC2 5'-flanking sequence contains elements sufficient for the appropriate expression of MUC2 in small intestinal goblet cells. Conversely, elements located outside this region appear necessary for efficient colonic expression, implying that the two tissues utilize different regulatory elements. Thus many, but not all, of the elements necessary for MUC2 gene regulation reside between bases -2864 and +17 of the 5'-flanking region.  (+info)

Epidermal growth factor system regulates mucin production in airways. (2/560)

Goblet-cell hyperplasia is a critical pathological feature in hypersecretory diseases of airways. However, the underlying mechanisms are unknown, and no effective therapy exists. Here we show that stimulation of epidermal growth factor receptors (EGF-R) by its ligands, EGF and transforming growth factor alpha (TGFalpha), causes MUC5AC expression in airway epithelial cells both in in vitro and in vivo. We found that a MUC5AC-inducing epithelial cell line, NCI-H292, expresses EGF-R constitutively; EGF-R gene expression was stimulated further by tumor necrosis factor alpha (TNFalpha). EGF-R ligands increased the expression of MUC5AC at both gene and protein levels, and this effect was potentiated by TNFalpha. Selective EGF-R tyrosine kinase inhibitors blocked MUC5AC expression induced by EGF-R ligands. Pathogen-free rats expressed little EGF-R protein in airway epithelial cells; intratracheal instillation of TNFalpha induced EGF-R in airway epithelial cells, and subsequent instillation of EGF-R ligands increased the number of goblet cells, Alcian blue-periodic acid-Schiff staining (reflecting mucous glycoconjugates), and MUC5AC gene expression, whereas TNFalpha, EGF, or TGFalpha alone was without effect. In sensitized rats, three intratracheal instillations of ovalbumin resulted in EGF-R expression and goblet-cell production in airway epithelium. Pretreatment with EGF-R tyrosine kinase inhibitor, BIBX1522, prevented goblet-cell production both in rats stimulated by TNFalpha-EGF-R ligands and in an asthma model. These findings suggest potential roles for inhibitors of the EGF-R cascade in hypersecretory diseases of airways.  (+info)

Weaning anorexia may contribute to local inflammation in the piglet small intestine. (3/560)

Compromising alterations in villus-crypt structure are common in pigs postweaning. Possible contributions of local inflammatory reactions to villus-crypt alterations during the weaning transition have not been described. This study evaluated local inflammatory responses and their relationship with morphological changes in the intestine in 21-d-old pigs (n = 112) killed either at weaning (Day 0) or 0.5, 1, 2, 4 or 7 d after weaning to either milk- or soy-based pelleted diets. Cumulative intake averaged <100 g during the first 2 d postweaning, regardless of diet. During this period of weaning anorexia, inflammatory T-cell numbers and local expression of the matrix metalloproteinase stromelysin increased while jejunal villus height, crypt depth and major histocompatibility complex (MHC) class I RNA expression decreased. Upon resumption of feed intake by the fourth d postweaning, villus height and crypt depth, CD8(+) T cell numbers, MHC class I RNA expression and local expression of stromelysin returned to Day 0 values. Together the results indicate that inadequate feed intake during the immediate postweaning period may contribute to intestinal inflammation and thereby compromise villus-crypt structure and function.  (+info)

Cloning of the gene gob-4, which is expressed in intestinal goblet cells in mice. (4/560)

We isolated the novel cDNA gob-4, which was shown to be expressed in intestinal goblet cells. The deduced amino acid sequence is similar to the gene coding for the Xenopus laevis cement gland-specific XAG-2. These sequence and expression data suggest this gene may be involved in the secretory function.  (+info)

Nitric oxide synthase inhibitor attenuates intestinal damage induced by zinc deficiency in rats. (5/560)

A nitric oxide synthase (NOS) inhibitor, NG-nitro-L -arginine methyl ester (L-NAME), was given to zinc-deficient (ZD) rats to determine whether it prevents the intestinal damage usually observed under these conditions. Weanling male rats were given free access to a ZD diet (2 mg zinc/kg), whereas control rats including pair-fed (PF) and ad libitum consumption (AL) groups were given a zinc-supplemented (50.8 mg zinc/kg) diet for 4 wk. Half of the ZD rats received L-NAME (0.3 g/L in drinking water) for 3 wk starting at the wk 2 of the deficient period. Plasma zinc concentration in ZD rats was significantly lower (P < 0.05) than that of AL and PF rats. Administration of L-NAME did not alter this concentration. Intestinal zinc concentration did not differ among groups. However, metallothionein-1 (MT-1) mRNA level was significantly lower in the intestine of ZD rats than in AL or PF rats. Treatment of ZD rats with L-NAME did not affect this level. Intestinal microvascular permeability evaluated by Evans blue showed significantly higher extravasation in ZD rats than in AL rats, whereas L-NAME administration inhibited the extravasation. Expression of inducible NOS mRNA was observed in intestine of ZD but not of AL or PF rats, and there was no significant difference between ZD rats, regardless of L-NAME treatment. The activity ratio of inducible NOS to total NOS in ZD rats not receiving L-NAME was significantly higher than that in AL rats or ZD rats treated with L-NAME (P < 0.05). The number of apoptotic-positive and goblet cells in intestinal villi was significantly higher in ZD rats compared with AL or PF rats. L-NAME administration in ZD rats reversed this effect. These results indicate that inhibition of NOS ameliorates zinc deficiency-induced intestinal damage in rats.  (+info)

Overexpression of glycine-extended gastrin in transgenic mice results in increased colonic proliferation. (6/560)

Gastrin is a peptide hormone involved in the growth of both normal and malignant gastrointestinal tissue. Recent studies suggest that the glycine-extended biosynthetic intermediates mediate many of these trophic effects, but the in vivo relevance of glycine-extended gastrin (G-Gly) has not been tested. We have generated mice (MTI/G-GLY) that overexpress progastrin truncated at glycine-72 to evaluate the trophic effects of G-Gly in an in vivo model. MTI/G-GLY mice have elevated serum and colonic mucosal levels of G-Gly compared with wild-type mice. MTI/G-GLY mice had a 43% increase in colonic mucosal thickness and a 41% increase in the percentage of goblet cells per crypt. MTI/G-GLY mice exhibited increased colonic proliferation compared with wild-type controls, with an expansion of the proliferative zone into the upper third of the colonic crypts. Continuous infusion of G-Gly into gastrin-deficient mice for two weeks also resulted in elevated G-Gly levels, a 10% increase in colonic mucosal thickness, and an 81% increase in colonic proliferation when compared with gastrin-deficient mice that received saline alone. To our knowledge, these studies demonstrate for the first time that G-Gly's contribute to colonic mucosal proliferation in vivo.  (+info)

IL-4 induces mucin gene expression and goblet cell metaplasia in vitro and in vivo. (7/560)

Goblet cell metaplasia and mucus hypersecretion are important features in the pathogenesis of asthma. The cytokine IL-4 has been shown to play a role in animal models of asthma, where it induces Th2 lymphocyte differentiation and B lymphocyte IgE class switch. IL-4 has also been implicated in the differentiation of goblet cells via effects on lymphocytes and eosinophils. In this study we hypothesized that IL-4 induces airway epithelial cell mucin gene expression and mucous glycoconjugate production by direct action on these cells. In vitro, cultured airway epithelial cells (NCI-H292) expressed IL-4R constitutively, and IL-4 (10 ng/ml) induced MUC2 gene expression and mucous glycoconjugate production. In vivo, mouse airway epithelial cells expressed IL-4R constitutively, and IL-4 (250 ng) increased MUC5 gene expression and Alcian blue/periodic acid-Schiff-positive staining at 24 h; IL-4 did not increase inflammatory cell numbers in airway tissue or in bronchoalveolar lavage. TNF-alpha and IL-1beta levels in bronchoalveolar lavage were not increased in response to IL-4 instillation. These results indicate that airway epithelial cells express IL-4R constitutively and that IL-4 directly induces the differentiation of epithelium into mucous glycoconjugate-containing goblet cells.  (+info)

Immunolocalization of muscarinic and VIP receptor subtypes and their role in stimulating goblet cell secretion. (8/560)

PURPOSE: To determine the subtypes of cholinergic muscarinic receptors and receptors for vasoactive intestinal peptide (VIP) present in rat conjunctival goblet cells and whether cholinergic agonists and VIP stimulate goblet cell secretion. METHODS: Immunofluorescence studies were performed using antibodies against the m1, m2, and m3 muscarinic receptor subtypes and VIP receptors 1 and 2 (VIPR1 and VIPR2). The lectin Ulex europeus agglutinin I was used to measure glycoconjugate secretion, the index of secretion, from goblet cells in an enzyme-linked lectin assay. In this assay, pieces of conjunctiva were placed on filter paper and incubated for 15 to 120 minutes, with or without increasing concentrations of the cholinergic agonist carbachol or VIP. The muscarinic antagonist atropine and the muscarinic receptor-subtype-selective antagonists pirenzepine (M1), gallamine (M2), and 4-4-diphenylacetoxy-N-(2-chloroethyl)-piperidine hydrochloride (4-DAMP mustard; M3) were incubated with carbachol to determine specificity of receptor activation. RESULTS: Immunoreactivity to M2 and M3 receptors was found on goblet cell membranes subjacent to the secretory granules. Immunoreactivity to M1 receptor was not on goblet cells but was on the stratitfied squamous cells. Immunoreactivity to VIPR2 was found on goblet cells with a localization similar to that of the M2 and M3 receptors. VIPR1 was not found on goblet cells or on the stratified squamous cells. Carbachol and VIP induced a time- and concentration-dependent stimulation of glycoconjugate secretion. Carbachol, at 10(-4) M, induced a threefold increase in glycoconjugate secretion, which was completely inhibited by atropine (10(-5) M). Carbachol-induced secretion was inhibited 54% +/- 8% by pirenzepine (10(-5) M), 69% +/- 14% by gallamine (10(-5) M), and 72% +/- 11% by 4-DAMP mustard (10(-5) M). A twofold increase in glycoconjugate secretion was obtained with VIP at 10(-8) M. CONCLUSIONS: Cholinergic agonists, through M2 and/or M3 muscarinic receptors, and VIP, through VIPR2, regulate conjunctival goblet cell secretion, suggesting that goblet cell secretion in vivo is under the control of parasympathetic nerves.  (+info)

Purpose: To demonstrate the signaling transduction of TGFbRII→Smads⊣SPDEF→Muc5/ac axis for conjunctival goblet cell differentiation.. Methods: We employed conditional deletion of transforming growth factor β receptor II (TGFβRII) in keratin 14-positive stratified epithelia. Phenotypic and biochemical analyses of the resultant ocular surface were compared to the wild-type littermates at various stages.. Results: We found that, in the absence of an external phenotype, the ocular surface epithelium develops properly, but young mice displayed conjunctival goblet cell expansion, demonstrating that TGFβ signaling is required for normal restriction of goblet cells within the conjunctiva. We observed increased expression of SAM-pointed domain containing ETS transcription factor (SPDEF) in stratified conjunctival epithelial cells in TGFβRII cKO mice, suggesting that TGFβ restricted goblet cell differentiation directly by repressing Spdef transcription. Gain-of-function of Spdef in keratin ...
For immunofluorescence microscopy, the eyes were enucleated with the lids intact and fixed in 4% formaldehyde in phosphate-buffered saline (PBS; 145 mM NaCl, 7.3 mM Na2HPO4, and 2.7 mM NaH2PO4 [pH 7.2]), for 4 hours at 4°C. The eyes were then rinsed in 5% sucrose dissolved in PBS, placed overnight in 30% sucrose dissolved in PBS at 4°C, embedded in OCT, and frozen. Cryostat sections (6 μm) were placed on slides (Colorfrost/Plus; Fisher Scientific, Pittsburgh, PA) and kept at −20°C until use. Cultured goblet cells (CGCs) grown on glass coverslips were fixed in absolute methanol. Tissue sections and CGCs were then washed in PBS and blocked in PBS containing 1% bovine serum albumin, 4% goat serum, and 0.2% to 0.3% Triton X-100. The NT antibodies (NGF, BDNF, NT3, and NT4) were used at a dilution of 1:800. The NTr antibodies (TrkA, TrkB, TrkC, and p75) were used at a dilution of 1:200. All antibodies were diluted in PBS containing 0.3% Triton X-100 and incubated for 48 hours at 4°C. The ...
Mammalian anterior gradient 2 (AGR2), an endoplasmic reticulum protein disulfide isomerase, is involved in cancer cell growth and metastasis, asthma, and inflammatory bowel disease. Mice lacking Agr2 exhibit decreased Muc2 protein in intestinal goblet cells, abnormal Paneth cell development, ileitis, and colitis. Despite its importance in cancer biology and inflammatory diseases, the mechanisms regulating agr2 expression in the gastrointestinal tract remain unclear. Here, we investigated the mechanisms that control agr2 expression in the pharynx and intestine of zebrafish by transient/stable transgenesis, coupled with motif mutation, morpholino knockdown, mRNA rescue, and chromatin immunoprecipitation. A 350 bp DNA sequence with a hypoxia-inducible response element (HRE) and fork head response element (FHRE) within a region -4.5 to -4.2 kbp upstream of agr2 directed EGFP expression specifically in the pharynx and intestine. No EGFP expression was detected in the intestinal goblet cells of ...
The conjunctiva is a mucous membrane that covers the sclera and lines the inside of the eyelids. Throughout the conjunctiva are goblet cells that secrete mucins to protect the eye. Chronic inflammatory diseases such as allergic conjunctivitis and early dry eye lead to increased goblet cell mucin secretion into tears and ocular surface disease. The purpose of this study was to determine the actions of the inflammatory mediators, the leukotrienes and the proresolution resolvins, on secretion from cultured rat and human conjunctival goblet cells. We found that both cysteinyl leukotriene (CysLT) receptors, CysLT(1) and CysLT(2,) were present in rat conjunctiva and in rat and human cultured conjunctival goblet cells. All leukotrienes LTB(4), LTC(4), LTD(4), and LTE(4), as well as PGD(2), stimulated goblet cell secretion in rat goblet cells. LTD(4) and LTE(4) increased the intracellular Ca(2+) concentration ([Ca(2+)](i)), and LTD(4) activated ERK1/2. The CysLT(1) receptor antagonist MK571 ...
Resolution of inflammation is an active process mediated by pro-resolution lipid mediators. As resolvin (Rv) D1 is produced in the cornea, pro-resolution mediators could be effective in regulating inflammatory responses to histamine in allergic conjunctivitis. Two key mediators of resolution are the …
BACKGROUND: Goblet cell hyperplasia is a classic but variable pathologic finding in COPD. Current literature shows that smoking is a risk factor for chronic bronchitis but the relationship of these clinical features to the presence and magnitude of large airway goblet cell hyperplasia has not been well described. We hypothesized that current smokers and chronic bronchitics would have more goblet cells than nonsmokers or those without chronic bronchitis (CB), independent of airflow obstruction. METHODS: We recruited 15 subjects with moderate to severe COPD, 12 healthy smokers, and 11 healthy nonsmokers. Six endobronchial mucosal biopsies per subject were obtained by bronchoscopy and stained with periodic acid Schiff-Alcian Blue. Goblet cell density (GCD) was quantified as goblet cell number per millimeter of basement membrane. Mucin volume density (MVD) was quantified as volume of mucin per unit area of basement membrane. RESULTS: Healthy smokers had a greater GCD and MVD than nonsmokers and COPD
Goblet cell in the lining of the nasal epithelium, coloured transmission electron micrograph (TEM). The goblet cell (yellow) is full of mucus granules (purple) and is surrounded by microvilli (orange) coated columnar epithelial cells (brown). The squamous nasal epithelium is made up of both ciliated (not seen here) and microvilli coated columnar epithelial cells. Goblet cells are interspersed through this nasal epithelial layer. The goblet cells secrete mucus onto the surface of the nasal cavity (where the surface of the ciliated and microvilli coated columnar epithelial cells are exposed in the nasal cavity). Cilia and microvilli become coated with sticky mucus that helps trap foreign objects such as dust, bacteria and pathogens, preventing them from entering the lungs. Coordinated, wave-like beating of the cilia propels the mucus to the back of the nasopharynx where it is swallowed, thus removing foreign objects.

The exposure of materials to the respiratory tract can result in a variety of tissue effects including irritation, inflammation and downstream effects such as goblet cell hyperplasia (GCH). GCH is the elevated expression of Goblet cells in the airway and is involved in various diseases that can lead to debilitation conditions. IIVS uses human reconstructed airway tissues (RHuA) from both MatTek and Epithelix to assess exposures that may lead to GCH as an indicator of risk to human health.. A variety of materials can induce changes to the respiratory epithelium. Some of these exposures result in low level toxicities or adverse events that may not manifest as overt cytotoxicity, but may perturb cell systems to generate signaling pathways resulting in the expression of inflammatory mediators such as cytokines. RHuA that are exposed to certain cytokines for prolonged periods of time will overexpress goblet cells. This effect requires several weeks and IIVS use of high quality, long-term cultures of ...
Innate immune signaling pathways contribute to the protection of host tissue when bacterially challenged. Colonic goblet cells are responsible for generating the two mucus layers that physically separate the luminalmicrobiota from the host epithelium. Analysis of colonic tissues from multiple mouse strains allowed us to identify a sentinel goblet cell (senGC) localized to the colonic crypt entrance. This cell nonspecifically endocytoses and reacts to the TLR2/1, TLR4, and TLR5 ligands by activating the Nlrp6 inflammasome downstream of TLR-and MyD88-dependent Nox/Duox reactive oxygen species synthesis. This triggers calcium ion-dependent compound exocytosis ofMuc2 mucin fromthe senGC and generates an intercellular gap junction signal; in turn, this signal induces Muc2 secretion from adjacent goblet cells in the upper crypt, which expels bacteria. Thus, senGCs guard and protect the colonic crypt from bacterial intruders that have penetrated the inner mucus layer. ...
Lung diseases that involve dysfunctional development and regeneration of the pseudostratified proximal airway epithelium are a leading cause of morbidity and mortality. A hallmark of the response of the proximal airways to both injury and disease is an increase in the goblet cell lineage with a concomitant increase in mucin production and altered morphology of the pseudostratified epithelium. We show that Foxp1/4 play a central role in restricting secretory cell fate in the proximal airways of the lung by regulation of a novel pathway involving direct repression of the protein disulfide isomerase Agr2. Ectopic expression of Agr2 alone can promote the goblet cell fate in the secretory epithelium of the lung. This result, along with previous findings that Agr2 is essential for intestinal goblet cell development (Zhao et al., 2010), suggests that Agr2 is a central player in defining goblet cell fate and function in the epithelium of multiple tissues including the lung and intestine. Given that ...
Fkh6 was deleted from the genome of embryonic stem cells by targeting the gene with a neomycin resistance gene, the standard technique for producing knockout mice through homologous recombination. Homozygous null mice (Fkh6−/−) did not express Fkh6 mRNA. Importantly, they also displayed changes in gastrointestinal epithelial cell proliferation and differentiation. Normally in fetal mice, the small intestine develops from a stratified into a columnar epithelium. This transition is associated with the invagination and condensation of mesenchyme. Rudimentary villi then grow, the timing of which was delayed in the Fkh6−/− mice. When villi did appear, they were less well developed and were shorter, wider and fewer in number. Although all four epithelial cell types (enterocytes, goblet cells, enteroendocrine cells, and Paneth cells) were present in the null mice, goblet cell numbers were increased in the proximal intestine. Normally there are fewer goblet cells in the proximal than in the ...
Next, we demonstrated, on the basis of morphological analysis of paraffin-embedded swiss rolls prepared from the intestinal tracts of DBZ-treated mice, that this Muc2 overexpression is associated with a massive and homogeneous goblet cell conversion, all along the small intestine and colonic crypts. Interestingly, at a high concentration of DBZ, this goblet cell conversion has been reported to be partial and heterogeneous in the intestinal adenomas of ApcMin mice (van Es et al., 2005), suggesting that some neoplastic cells could be resistant to GSI. Altogether, these findings suggest that the early steps of intestinal neoplasia are characterized by the resistance of some intestinal epithelial cells to the effect of GSI on goblet cell conversion, even at high concentrations. Finally, we also showed that DBZ elicits a homogeneous increase in lysozyme-positive Paneth cells in their normal location, the small intestine, a finding in line with reports using Math1-deficient mice, showing that Math1 ...

Background: The absorptive and goblet cells are the main cellular types encountered in the intestine epithelium. The cell lineage Caco-2 is a model commonly used to reproduce the features of the bowel epithelium. However, there is a strong debate regarding the value of Caco-2 cell culture to mimick in vivo situation. Indeed, some authors report in Caco-2 a low paracellular permeability and an ease of access of highly diffusible small molecules to the microvilli, due to an almost complete lack of mucus. The HT29-5M21 intestinal cell lineage is a mucin-secreting cellular population. A co-culture system carried out in a serum-free medium and comprising both Caco-2 and HT29-5M21 cells was developed. The systematic use of a co-culture system requires the ...
Cystic fibrosis (CF) results from mutations in CFTR, which encodes an anion channel that mediates transepithelial secretion of chloride and bicarbonate. A hallmark of CF is mucoviscidosis, the secretion of tenacious, viscous mucus that plugs ducts and glands of epithelia-lined organs, including the lungs and intestines. Goblet cells secrete mucins; however, it is not clear if these cells have altered exocytosis in the CF intestine. Jinghua Liu and colleagues at the University of Missouri evaluated goblet cells within intestinal organoid cultures from a murine CF model. Compared to those from WT mice, CF goblet cells exhibited altered exocytosis, including granule swelling and incomplete mucus discharge. Additionally, CF goblet cells exhibited distorted morphology and ectopic granule localization. Increasing the luminal bicarbonate concentration largely restored abnormal exocytosis defects, suggesting goblet cell alterations directly result from loss of CFTR function. Mucin granules within CF ...
Differentiated primary cultures of airway epithelia. Cells were obtained from the University of Iowa Cells and Tissue Core. Epithelial cells were isolated from the trachea and bronchi by enzymatic digestion, seeded onto collagen-coated, semipermeable membranes (0.6 cm2 Millicell-PCF; MilliporeSigma), and grown at the air-liquid interface as previously described (142). Culture medium, a 1:1 mixture of DMEM/F12, was supplemented with 2% Ultroser G (PALL Corp.). Differentiated epithelial cells were used at least 14 days after seeding. All experiments were performed on passage-0 primary cells obtained from fresh tissue. Media were changed every 2 days. At every media change, 20 μl basolateral media were uniformly added to the apical surface to allow basolateral and apical exposure to treatment conditions. Treatment conditions included IL-13 (20 ng/ml), IL-17 (20 ng/ml), geldanamycin (25 μM), and HDAC6 inhibitor ISOX (10 μM). Treatment durations are indicated in the results section corresponding ...

Omentin-1, also known as intelectin-1, is a recently identified novel adipocytokine of 313 amino acids, which is expressed in visceral (omental and epicardial) fat as well as mesothelial cells, vascular cells, airway goblet cells, small intestine, colon, ovary, and plasma. The level of omentin-1 expression in (pre)adipocytes is decreased by glucose/insulin and stimulated by fibroblast growth factor-21 and dexamethasone. Several lines of experimental evidence have shown that omentin-1 plays crucial roles in the maintenance of body metabolism and insulin sensitivity, and has anti-inflammatory, anti-atherosclerotic, and cardiovascular protective effects via AMP-activated protein kinase/Akt/nuclear factor-κB/mitogen-activated protein kinase (ERK, JNK, and p38) signaling ...
They noticed that the airway lining kept an excess of goblet cells (mucus-producing cells) because of a cup-like shape. The number of goblet cells increased as a result of two cellular mechanisms. One mechanism let the cells live longer because of the cilia, small hairs that help remove remains out of the lungs. The other mechanism provoked those cells to change into goblet cells ...

Background: Ovarian cancer G protein-coupled receptor 1 (OGR1) stimulation by extracellular protons causes the activation of G proteins and subsequent cellular functions. However, the physiological and pathophysiological roles of OGR1 in airway responses remain largely unknown.. Objective: We examined whether OGR1 is involved in the asthmatic inflammatory responses.. Methods: Mice deficient in OGR1 were sensitized and challenged with ovalbumin (OVA) to measure airway inflammation and hyperresponsiveness. To examine the involvement of dendritic cells (DCs) in the airway responses, OVA-pulsed bone marrow-derived DCs were intratracheally transferred. Functional OGR1 expression and its activities in relation to migration in DCs were examined in vitro.. Results: OGR1-deficient mice are resistant to the cardinal features of asthma, including airway eosinophilia, bronchial hyperresponsiveness, and goblet cell metaplasia, in association with a remarkable inhibition of TH2 cytokine production, in an ...

Goblet cells reside throughout the gastrointestinal (GI) tract and are responsible for the production and preservation of a protective mucus blanket by synthesizing and secreting high molecular weight glycoproteins known as mucins. The concept of the mucus layer functioning as a dynamic protective barrier is suggested by studies showing changes in mucins in inflammatory conditions of the GI tract, by the altered goblet cell response in germ-free animals, and by the enhanced mucus secretion seen in response to infections. The mucin-containing mucus layer coating the GI epithelium is the front line of innate host defense. Mucins are likely to be the first molecules that invading pathogens interact with at the cell surface and thus, can limit binding to other glycoproteins and neutralize the pathogen. This review will focus on what is known about goblet cell response in various GI infections and the regulatory networks that mediate goblet cell function and mucin production in response to intestinal insults
It has been found by immunohistochemical staining that antigens normally found in gastric and/or intestinal epithelial cells are expressed in most differentiated duct cell carcinomas of the pancreas. Among 88 such tumors, 93% and 92%, respectively, expressed M1 and cathepsin E, markers of gastric surface-foveolar epithelial cells, 51% expressed pepsinogen II, a marker of gastroduodenal mucopeptic cells, 48% expressed CAR-5, a marker of colorectal epithelial cells, and 35% expressed M3SI, a marker of small intestinal goblet cells. Most of the tumors also expressed normal pancreatic duct antigens; 97% expressed DU-PAN-2, and 59% expressed N-terminus gastrin-releasing peptide. In agreement with these findings, electron microscopy revealed malignant cells with fine structural features of gastric foveolar cells, gastric mucopeptic cells, intestinal goblet cells, intestinal columnar cells, pancreatic duct epithelial cells, and cells with features of more than one cell type. Normal pancreatic duct epithelium
Epithelial hyperplasia and metaplasia are common features of inflammatory and neoplastic disease, but the basis for the altered epithelial phenotype is often uncertain. Here we show that long-term ciliated cell hyperplasia coincides with mucous (goblet) cell metaplasia after respiratory viral clearance in mouse airways. This chronic switch in epithelial behavior exhibits genetic susceptibility and depends on persistent activation of EGFR signaling to PI3K that prevents apoptosis of ciliated cells and on IL-13 signaling that promotes transdifferentiation of ciliated to goblet cells. Thus, EGFR blockade (using an irreversible EGFR kinase inhibitor designated EKB-569) prevents virus-induced increases in ciliated and goblet cells whereas IL-13 blockade (using s-IL-13Rα2-Fc) exacerbates ciliated cell hyperplasia but still inhibits goblet cell metaplasia. The distinct effects of EGFR and IL-13 inhibitors after viral reprogramming suggest that these combined therapeutic strategies may also correct ...

Damage to and shedding of the airway epithelium is observed in bronchial biopsies in asthma. The shedded epithelial cell clusters have been described in sputum as creola bodies. It is however still under debate whether this is an artifact of the sampling procedure. Thus, the loss of surface epithelium in mild asthma is variable and in some studies it has not been significant different from controls (7). In other studies (8) a correlation between bronchial hyperresponsiveness and the degree of epithelial shedding have been observed. In COPD, squamous cell metaplasia and goblet cell hyperplasia and loss of ciliated epithelial cells are reported in the large airways (2).. Increased numbers of goblet cells is observed in chronic bronchitis (9). In fatal asthma as well as in chronic bronchitis, the number of mucus glands is increased. There are data supporting that this may not be the case in COPD with a marked emphysematous phenotype (10). In severe asthma, the airways can be obstructed by mucus. ...

In the gastric mucosa of a patient with Helicobacter pylori infection and a precancerous lesion called incomplete intestinal metaplasia (Genta stain), the gastric cells lining a gland have been replaced by absorptive intestinal cells with visible brush border and goblet cells, which are normally present in the intestine, but not in the stomach. Goblet cells contain acidic mucins stained blue by Alcian blue. This type of precancerous transformation is caused by long-term infection with H. pylori, visible in the lumen of the gland as curved bacterial rods stained black by silver stain. A few bacteria invade the goblet cells and can be found within blood capillaries, where they bind to red blood cells (see Aspholm et al. 2006).. ...

Members of the trefoil family are characterized by having at least one copy of the trefoil motif, a 40-amino acid domain that contains three conserved disulfides. They are stable secretory proteins expressed in gastrointestinal mucosa. Their functions are not defined, but they may protect the mucosa from insults, stabilize the mucus layer and affect healing of the epithelium. This gene is expressed in goblet cells of the intestines and colon. This gene and two other related trefoil family member genes are found in a cluster on chromosome 21.

We have previously found that tracheal instillation of trimellitic anhydride conjugated to guinea pig serum albumin induces acute bronchoconstriction and airway plasma exudation in sensitised animals, responses mediated primarily via histamine release. In the present study, neural mechanisms mediating bronchoconstriction and goblet cell secretion were determined in trimellitic anhydride-sensitised guinea pigs using the ganglionic blocker hexamethonium to eliminate efferent reflex mechanisms, pretreatment with capsaicin to eliminate afferent mechanisms, or cimetidine and mepyramine to eliminate ...
The intestinal epithelium is rich in γδ T cells and the gut is a site of residence for a wide variety of pathogens, including nematodes. Although CD4+ T-cell receptor (TCR) -αβ+ T helper type 2 T cells are essential for the expulsion of intestinal nematodes, little information is available on the function of γδ T cells in this type of infection. Here, we demonstrate two major functions of γδ T cells as a potently protective T-cell population against Nippostrongylus brasiliensis infection using γδ T-cell-deficient (TCR-δ(-/-) ) mice. First, γδ T cells are required to initiate rapid expulsion of adult worms from the intestine and to limit egg production. Second, γδ T cells prevent the pathological intestinal damage associated with nematode infection, evident by increased clinical disease and more severe microscopic lesions in infected TCR-δ(-/-) mice. γδ T-cell deficiency led to delayed goblet cell hyperplasia in association with reduced expression of phosphorylated STAT6, MUC2, Trefoil

Disturbance of the mucus layer has been implicated variety of intestinal diseases. We have recently investigated the the mucus layer in colon ischemia-reperfusion (IR). Using a newly and rat colon IR model, we showed that colon ischemia leads to mucus breakdown. This allowed intraluminal bacteria to interact with the epithelium, which was associated with an inflammatory response. found goblet cells to respond immediately by expelling their mucin the gut lumen, which flushed bacteria from the colonic crypts and rapid restoration of the mucus layer during reperfusion. Our study might why ischemic colitis tends to have favorable outcomes and can often be conservatively.. AB - In ...
Bronchi are tube like structures that allow air to be transported from the surrounding atmosphere to the lung. The respiratory system (airways) consists of the trachea (essentially a large bronchi) that branch off into smaller and smaller bronchi before reaching the most distal lung alveoli, where oxygen can be transferred to the blood. The respiratory bronchus is lined by respiratory epithelium comprising an admixture of pseudostratified ciliated columnar epithelium, goblet cells (mucin producing cells also termed mucous cells) and basal cells that function as progenitor cells for both the ciliated columnar cells and goblet cells. Ciliated cells are about five times more numerous than goblet cells in the central airways and the ratio of ciliated cells increases in the smaller and peripheral bronchi (bronchioles) as the goblet cells diminish. The basal cells are more abundant in the proximal airways, where they form more or less, a continuous layer and gradually diminish in number in peripheral ...
May be involved in mediating calcium-activated chloride conductance (PubMed:8537359). May play critical roles in goblet cell metaplasia, mucus hypersecretion, cystic fibrosis and AHR. May be involved in the regulation of mucus production and/or secretion by goblet cells. Involved in the regulation of tissue inflammation in the innate immune response. May play a role as a tumor suppressor. Induces MUC5AC.
The airway epithelium made up of ciliated cells and goblet cells forming a tight barrier to the outside world. Inset: In a healthy airway epithelium, goblet cells secrete mucin proteins that are incorporated into a thick gel that coats the luminal side of airways and is propelled out of the lung by the beating of cell-surface cilia. In asthma and other airway disease, this mucociliary defense mechanism does not function as effectively and mucus can become trapped and form mucus plugs. Four general mechanisms of mucus dysfunction have been described, including the following: (a) mucus dehydration leading to collapse of the periciliary brush mucus layer, (b) excess production of mucins such as Muc5AC, (c) abnormal tethering of mucus strands to the goblet cell surface, and (d) mucus crosslinking during inflammation. In the presence of eosinophilic airway inflammation, eosinophil peroxidase (EPX), together with other oxidant molecules, can crosslink mucus strands, leading to a more viscous gel that ...
Ecabet Sodium is a prescription eye drop for the treatment of dry eye syndrome. It is a new class of molecules that increases the quantity and quality of mucin produced by conjunctival goblet cells and corneal epithelia. Mucin is a glycoprotein component of tear film that lubricates while retarding moisture loss from tear evaporation. Ecabet Sodium is currently marketed in Japan as an oral agent for treatment of gastric ulcers and gastritis.
Columnar epithelial cells are elongated and column-shaped and have a height of at least four times their width. Their nuclei are elongated and are usually located near the base of the cells. Columnar epithelium forms the lining of the stomach and intestines. The cells here may possess microvilli for maximising the surface area for absorption and these microvilli may form a brush border. Other cells may be ciliated to move mucus in the function of mucociliary clearance. Other ciliated cells are found in the fallopian tubes, the uterus and central canal of the spinal cord. Some columnar cells are specialized for sensory reception such as in the nose, ears and the taste buds. Hair cells in the inner ears have stereocilia which are similar to microvilli. Goblet cells are modified columnar cells and are found between the columnar epithelial cells of the duodenum. They secrete mucus, which acts as a lubricant. Single-layered non-ciliated columnar epithelium tends to indicate an absorptive function. ...

Hypoxia is an important regulator of normal and cancer stem cell (CSC) differentiation. Colorectal CSCs from SW1222, LS180, and CCK81 colorectal cancer-derived cell lines are able to differentiate into complex 3D lumen-containing structures in normoxia, whereas in hypoxia, they form undifferentiated dense colonies that have reduced expression of the enterocyte differentiation marker CDX1, lack goblet cell formation, and have increased expression of BMI1 and activated Notch1. Hypoxia increases the clonogenicity of CSCs, which is cumulative as each round of hypoxia enriches for more CSCs. The hypoxic phenotype is reversible, because cells from hypoxic-dense colonies are able to reform differentiated structures when regrown in normoxia. We show that CDX1 is able to stimulate the generation of lumens even in hypoxia and has a negative feedback on BMI1 expression. Knockdown of CDX1 reduces lumen formation but does not affect goblet cell formation, suggesting that enterocytes and goblet cells form from
Dietary factors, including bile acids, are important in the causation of colorectal cancer (CRC). We have previously shown that in vitro exposure of colorectal mucosal biopsies to low concentrations of bile acids produces apoptosis selectively in goblet cells. Apopotosis is an important mechanism for clearing DNA-damaged cells. Inhibition of apoptosis would result in increasing accumulation of DNA-damaged cells, resulting in increased cancer risk. We compared the percentage of apoptosis induced by bile acids in mucosal biopsies from CRC patients with that of noncancer subjects.. Mucosal biopsies from 15 to 20 cm from the anal verge were incubated in 1 mm sodium deoxycholate, and the percentage of goblet cells undergoing apoptosis was quantitated. Seven patients with a history of CRC within the previous 5 years were compared with 18 noncancer subjects [4 neoplasia free and 14 with small (≤9 mm) polyps only].. The CRC patients had a significantly lower percentage of apoptosis than noncancer ...
An asthma attack is when, after a period of time when aperson has had only a few or no symptoms of asthma, the asthma gets worse all of a sudden, usually because of being exposed to one or more triggers. When the asthma attack happens, the tissue inside the airways swell because of inflammation - which is how the body tries to protect itself from harmful things, like germs and irritants. When the tissues swell the opening (called the lumen) in the airway gets very narrow. The smooth muscles (which are the kind of muscles in the body that do not contract voluntarily, like the ones in the arm) around the bronchi and bronchioles begin to spasm or contract which makes the opening in the airway even narrower. This is called a bronchospasm. Inside the lining of the airways are glands called, submucosal glands, and above them, closer to the opening in the airway are cells called goblet cells - because they are shaped kind of like a goblet, which is a type of cup. The submucosal glands and the goblet ...

Air is drawn in to the lungs via the trachea due to low pressure in the lungs, created by movement of the ribs and diaphragm. The trachea divides into two bronchi which carry air to and from each lung. Within in each lung there are bronchioles leading to aveoli which are the site of gas exchange.. Everyone has a thin layer of mucus produced continuously from goblet cells in the walls of the airway. Any dust, debris or microorganisms become trapped in the mucus and are continually removed by the wave-like beating of cilia that cover the epithelial cells.. People with CF have mucus that is drier than usual resulting in a sticky mucus layer that the cilia find difficult to move. This increases the chances of lung infection and makes gas exchange less efficient.. White blood cells fight the infections and pathogens within the mucus but as they die they break down, releasing DNA which makes the mucus even stickier. Repeated infections can weaken the bodys ability to fight the pathogens and cause ...
