Oesophageal adenocarcinoma (OAC) is an aggressive malignancy with poor prognosis, and incidence is increasing rapidly in the Western world. Mucosal-associated invariant T (MAIT) cells recognize bacterial metabolites and kill infected cells, yet their role in OAC is unknown. We aimed to elucidate the role of MAIT cells during cancer development by characterizing the frequency, phenotype, and function of MAIT cells in human blood and tissues, from OAC and its pre-malignant inflammatory condition Barretts oesophagus (BO). Blood and tissues were phenotyped by flow cytometry and conditioned media from explanted tissue was used to model the effects of the tumor microenvironment on MAIT cell function. Associations were assessed between MAIT cell frequency, circulating inflammatory markers, and clinical parameters to elucidate the role of MAIT cells in inflammation driven cancer. MAIT cells were decreased in BO and OAC blood compared to healthy controls, but were increased in oesophageal tissues, ...

The quest for new therapeutics and better follow-up of patients with inflammatory bowel diseases (IBD) requires the clearest possible picture of the immunological mechanisms underlying these complex pathologies. We identified recently a potential new player in this destructive game, a non-conventional T cell subset called Mucosal-Associated Invariant T (MAIT) cells. These cells were initially identified on the basis of their use of a semi-invariant TCR, made of the invariant V7.2-J33 TCR chain (now TCRAV1S2-AJ33) paired to a limited number of different TCR chains (1). Human MAIT cells are mostly CD8+ T cells with an effector/memory phenotype and expression of various chemokine receptors involved in extra-lymphoid migration. They also express most markers associated with IL-17 producing T cells, such as RORt, high CD161, IL-23R and CD26. They make up to 10% of peripheral blood and intestinal lamina propria T cells, and are even more abundant in the liver (2). The most striking feature of

The role unconventional T cells play in protective immunity in humans is unclear. Mucosal-associated invariant T (MAIT) cells are an unconventional T

Mucosal-associated invariant T (MAIT) cells are an innate-like T-cell population involved in anti-bacterial immunity. In human beings, MAIT cells are abundant, comprising ~10% of the CD8(+) T-cell compartment in blood. They are enriched at mucosal sites and are particularly prevalent within the liver. MAIT cells are defined by the expression of a semi-invariant T-cell receptor (Vα7.2-Jα33/12/20) and are restricted by the non-polymorphic, highly evolutionarily conserved MHC class Ib molecule, MHC-related protein (MR)1. MR1 has recently been shown to present an unstable pyrimidine intermediate derived from a biosynthetic precursor of riboflavin; riboflavin biosynthesis occurs in many bacteria but not in human beings. Consistent with this, MAIT cells are responsive to riboflavin-metabolizing bacteria, including Salmonella. In mouse models, MAIT cells have been shown to play a non-redundant role in anti-bacterial immunity, including against Escherichia coli, Klebsiella pneumoniae, and Mycobacterium bovis

The mucous membranes (or mucosae; singular: mucosa) are linings of mostly endodermal origin, covered in epithelium, which are involved in absorption and secretion. They line various body cavities that are exposed to the external environment and internal organs. It is at several places continuous with skin: at the nostrils, the lips, the ears, the genital area, and the anus. The sticky, thick fluid secreted by the mucous membranes and gland is termed mucus. The term mucous membrane refers to where they are found in the body and not every mucous membrane secretes mucus. Body cavities featuring mucous membrane include most of the respiratory system. The glans penis (head of the penis) and glans clitoridis and the inside of the prepuce (foreskin) and clitoral hood are mucous membranes, not skin. ...

A new study published by the Journal of Clinical Investigation has revealed that chronic inflammation is caused by obesity and alters the immune system and the gut microbial environment. The changes to the immune system consist of alterations to the mucosal-associated invariant T (MAIT) cells. MAIT cells are an innate-like T cell population that recognizes bacterial ligands and is enriched in mucosal and inflamed tissues. Obesity is associated with low-grade inflammation in fat tissue and dysfunctional fat cells produce inflammatory molecules. The fat tissue accumulation of immune cells such as macrophages, lymphocytes, neutrophils, and mast cells is a contributing factor in obesity and obesity-induced type 2 diabetes (T2D). In the fat tissue of lean people, the innate immune semi-invariant natural killer T (iNKT) cells are enriched in contrast to the fat tissue of obese patients. Mucosal-associated invariant T (MAIT) cells are a novel subset of innate-like immune cells found in peripheral ...

As the primary site of HIV-1 replication is the mucosa, a desirable feature of a HIV-1 vaccine would be the generation of immune responses at mucosal sites. We created an optimized CCL27 DNA construct as well as optimized SIV gag, pol, and env plasmids for immunizing rhesus macaques. Macaques (n=5/group) were immunized with SIV plasmids +/- CCL27. Both immunization groups had significant IFN-g responses against the encoded SIV antigens (~12,000 SFU/106 PBMCs). CD8+ T cell proliferation as measured by CFSE staining was similar between the groups at ~22%. While systemic immune responses were robust, co-delivery of CCL27 did not adjuvant peripheral responses similar to what was observed in mice. Interestingly, macaques that received CCL27 had greater antigen specific IgA at mucosal sites including bronchial lavage and fecal samples. In addition, CD4+ T cells secreting effector cytokines were enhanced in the CCL27 group at mucosal, but not peripheral sites when compared to the antigenic group alone. ...

Mucosal epithelia are the first tissue sites of contact of HIV with the human body during the course of infection, and these play a critical role in determining its success in establishing systemic infection. We have shown that experimental disruption of tight junctions of mucosal epithelium may facilitate HIV transmission across mucosal epithelia by paracellular penetration, which requires no viral replication and, therefore, antiretroviral therapy would not be expected to block such transmission. Human papillomavirus (HPV) is the most common sexually transmitted agent of the mucosal epithelium. We have also shown that the tight junctions in HPV-infected epithelial anal lesions are disrupted, suggesting that HPV dissemination within the mucosal epithelium may increase the risk of HIV transmission. It is well documented that oncogenic type HPV-infected anogenital epithelial lesions contain elevated levels of proinflammatory cytokines, including interferon gamma (IFN-_) and tumor necrosis ...

In the previous entry commented that many times the mucous membranes are important as indicative of the state of health of our dog. I take photos of my dog that I used in the previous post to show what would be a normal coloration of mucous membranes.. Usually the mucous membranes have a pinkish color. If they appear paler (in some cases they become completely white), they are indicative of anemia, severe bleeding or shock. Bluish mucous membranes indicate Cyanosis (Abnormal amount of hemoglobin, molecule that is responsible for transporting oxygen). If they are yellowish they are a sign of jaundice (increase of bilirubin) and therefore of a problem in the liver.. If they are dry it means that the animal is dehydrated.. The mucous membranes also serve to assess the Capillary Refill Time (CRT). It is a quick test to assess blood circulation. It is measured by pressing with a finger the mucosa (usually the gingival), after pressing a white mark remains in the place where we press with the finger, ...

Bacterial adhesins promote colonization at the initial stages of an infection by mediating attachment to host tissues, thus avoiding nonspecific host defenses such as mechanical clearance and allowing bacterial multiplication to occur within the host (1). To exert these functions, adhesins need to be presented at the surface of the bacterium. Like typical adhesins, B. pertussis FHA attaches the bacterium to receptors in the respiratory tract (17-21, 28). However, in addition to being surface-associated, large amounts of FHA are also released into the extracellular milieu (15). This has so far only been observed in vitro. In this work, we show for the first time that FHA is likely to also be released in vivo, and that its secretion is necessary for efficient colonization in a mouse model of infection. Our results support the paradigm that the secreted form of bacterial adhesins may participate in pathogenesis.. The use of B. pertussis strains deficient in FHA release but presenting FHA ...

Mucosal melanoma is a rare disease epidemiologically and molecularly distinct from cutaneous melanoma developing from melanocytes located in mucosal membranes. Little is known about its therapy. In this paper, we aimed to evaluate the results of immunotherapy and radiotherapy in a group of patients with advanced mucosal melanoma, based on the experience of five high-volume centers in Poland and Italy. There were 82 patients (53 female, 29 male) included in this retrospective study. The median age in this group was 67.5 (IQR: 57.25–75.75). All patients received anti-PD1 or anti-CTLA4 antibodies in the first or second line of treatment. Twenty-three patients received radiotherapy during anti-PD1 treatment. In the first-line treatment, the median progression-free survival (PFS) reached six months in the anti-PD1 group, which was statistically better than 3.1 months in the other modalities group (p = 0.004). The median overall survival (OS) was 16.3 months (CI: 12.1–22.3) in the whole cohort.

Often it causes big discomfort for a woman and it makes sexual life of a woman very complicated and reduces her life quality. Until now the treatment alternative was hormonal therapy (which is often contraindicated, e.g. after the treatment of breast cancer, or not recommended), phytoestrogens therapy (unfortunately, it is effective not for all women) and lubricants for improving sexual intercourse.. Thanks to the most advanced technology, the treatment with the laser Er:YAG (SMOOTH) is a safe and effective way for a women to get rid of vaginal mucosa atrophy symptoms and to feel comfortable in her everyday life and her intimate life.. ...

This study provides evidence that the female cervicovaginal mucosa can be an effective site for induction and boosting of effector memory CD8+ T cell responses using a non-replicating viral vector. Previous studies involving live viruses or attenuated replicating vectors left open the possibility that the presence of these cells in the cervicovaginal mucosa might have resulted from their immune induction at remote sites. Trafficking of the virus/vector and expression of the antigen in other tissues could lead to subsequent recruitment of immunocytes to the cervicovaginal mucosa. We have focused our studies on the induction of effector T cell responses, rather than antibodies, because the efficient induction of cervicovaginal mucosa T cells by a non-replicating vaccine had not previously been demonstrated. In contrast, it is now recognized, thanks to the remarkable efficacy of the commercial HPV prophylactic vaccines, that systemic immunization with a protein antigen, in this case a virus-like ...

Background: Streptococcus pneumoniae (the pneumococcus) remains a leading cause of infectious mortality worldwide. Acquisition of the pneumococcus occurs at the nasopharyngeal mucosa and elicits a rapid influx of neutrophils (PMNs) to the nasal lumen. However, the pneumococcus efficiently eludes clearance by PMNs and persists in the nasopharynx weeks after the acute inflammatory response recedes, amplifying the risk of invasive disease. A growing number of studies implicate the secreted phospholipid platelet-activating factor (PAF) as an important local mediator of PMN recruitment and activation in response to mucosal infections. While the pneumococcus has been shown to secrete a cell wall-bound esterase, Pce, which efficiently hydrolyzes PAF in vitro, it remains unknown whether regulation of local PAF concentration influences pneumococcal survival during colonization. Methods: We make use of atraumatic colonization of the murine nasopharynx to model carriage in the human upper respiratory ...

A survey based on both literary data and the authors own results, concerning the mechanisms of sIgA-mediated antibacterial immunity, is presented. Secretory IgA is characterized as a specific component of the immune system of mucous membranes, which can recognize harmful bacterial and distinguish them from indigenous microflora physiologically colonizing the mucous membranes, to fix them to the mucous membrane surface and to direct further factors, such as mucin, lysozyme,etc. (which form the effector component of the mucous membrane immunity system) for thvir final inactivation and neutralization.

Humans have populations of innate-like T lymphocytes with an invariant TCR α-chain that recognize nonpeptide Ags, including invariant NKT (iNKT) cells and mucosal-associated invariant T (MAIT) cells. iNKT cell involvement in human asthma is controversial, whereas there has been little analysis of MAIT cells. Using peripheral blood cells from 110 participants from the Urban Environment and Childhood Asthma (URECA) birth cohort study, these cells were analyzed for number and function. We determined whether iNKT cell or MAIT cell frequency at 1 y is correlated with the cytokine polarization of mainstream CD4+ T cells and/or the development of asthma by age 7 y. Dust samples from 300 houses were tested for iNKT cell antigenic activity. Our results show that a higher MAIT cell frequency at 1 y of age was associated with a decreased risk of asthma by age 7 y. The frequency of MAIT cells was associated with increased production of IFN-γ by activated CD4+ T cells from the URECA cohort. iNKT cell ...

Bronchial asthma often starts in early childhood. Clinical manifestation of the disease is likely due to inflammatory processes in the airways initiated by various stimuli. Developed remodelling is regularly observed in the bronchial mucosa of adult asthmatics but we still lack information about its onset and latter development with the natural course of the disease. In this study, we analysed histological findings in bronchial biopsies obtained from very young children (under 4 yr of age). We hypothesized that initial undetectable changes in the airway epithelium of children predisposed to asthma may be one of the first mechanisms leading to morphological changes in the bronchial mucosa. ...

The C-type lectin-like receptor CD161 is expressed by lymphocytes found in human gut and liver, as well as blood, especially natural killer (NK) cells, T helper 17 (Th17) cells, and a population of unconventional T cells known as mucosal-associated invariant T (MAIT) cells. The association of high CD161 expression with innate T-cell populations including MAIT cells is established. Here we show that CD161 is also expressed, at intermediate levels, on a prominent subset of polyclonal CD8+ T cells, including antiviral populations that display a memory phenotype. These memory CD161(int)CD8+ T cells are enriched within the colon and express both CD103 and CD69, markers associated with tissue residence. Furthermore, this population was characterized by enhanced polyfunctionality, increased levels of cytotoxic mediators, and high expression of the transcription factors T-bet and eomesodermin (EOMES). Such populations were induced by novel vaccine strategies based on adenoviral vectors, currently in trial

Before treating gastritis, it is important to determine the cause of the condition first.. It is difficult to treat gastritis if the cause of the damage to the mucous layer is not eliminated first.. Many causes can be remedied at home, by simply eliminating things from your diet such as alcohol, excessive fats, or over the counter pain relievers.. Other causes may take a doctor to diagnose and treat such as the H. Pylori infection.. Remedies for Gastritis aim at soothing the various symptoms and restoring the mucous layer of the stomach. Slippery elm is highly effective at symptom relief because the mucilage has anti-inflammatory properties which can sooth the inflammation of the stomach lining.. The mucilage also has a gel viscosity that coats the stomach in a protective layer, giving it protection from further damage.. This protection allows healing to take place by aiding the stomach in rebuilding the stomach lining.. Slippery elm is often taken with the amino acid glutamine, Acidophilus, ...

Under the tongue, we as a whole have a mucous film. Mucous films are thin layers of tissue that line depressions in the body and spread the outside of our organs. Some mucous layers do as the name proposes, and discharge bodily fluid-like the films that line the nose.. These films are slightly contrasted with skin, which has numerous layers. Underneath is a free layer of connective tissue, in addition to loads of little vessels. Head to a mirror and investigate your tongue, and youll see a few.. When you hold CBD under your tongue, the dynamic mixes in the arrangement are consumed through the mucous layer and enter the circulation system.

BACKGROUND: Mucosal melanoma (MM) is a rare but diverse cancer entity. Prognostic factors are not well established for Caucasians with MM. PATIENTS AND METHODS: We analysed the disease course of 444 patients from 15 German skin cancer centres. Disease progression was determined with the cumulative incidence function. Survival times were estimated with the Kaplan-Meier method. Prognostic parameters were identified with multivariate Cox regression analysis. RESULTS: Common anatomic sites of primary tumours were head and neck (MMHN, 37.2%), female genital tract (MMFG, 30.4%) and anorectal region (MMAN, 21.8%). MMAN patients showed the highest vertical tumour thickness (p = 0.001), had a more advanced nodal status (p = 0.014) and a higher percentage of metastatic disease (p = 0.001) at diagnosis. Mutations of NRAS (13.8%), KIT (8.6%) and BRAF (6.4%) were evenly distributed across all tumour site groups. Local relapses were observed in 32.4% and most commonly occurred in the MMHN group (p = 0.016). ...

If you look at the response rate in those who got ipilimumab with nivolumab, a more potent and somewhat more toxic regimen, we are looking at a 37% response rate for the nivolumab patients versus a 60% response rate for those who had standard cutaneous melanoma. The progression-free survival was only about 5.5 months in the combination regimen versus 11-plus months for those with standard cutaneous melanoma.[1] It seemed clear that patients will not do quite as well when they have mucosal melanoma as when they have cutaneous melanoma, when receiving either PD-1 antibodies such as nivolumab alone or in combination with ipilimumab. However, it is clear that there is benefit. Patients will respond. Some patients will have long-term survival. It remains to be seen what drugs could be added to these regimens that will bring the response rate, the progression-free survival, and the overall survival up to what we see with cutaneous melanoma patients. ...

The PIANO trial is an open-label, single-arm, multicentre phase II trial of PLX3397 in advanced acral and mucosal melanoma. All eligible patients will receive PLX3397 1000mg/day as monotherapy and will remain on treatment as long as they are deriving benefit (at the treating Investigators discretion).. The primary objective of this study is to assess the efficacy of PLX3397 by review of the number of patients who are progression-free at 6 months. Additional objectives include assessing the safety of PLX3397, overall survival and (for a sub-set of patients) biomarker research.. A maximum of 24 eligible patients may be treated in this study. In order to recruit 24 patients, it is expected that a total of approximately 240 patients will need to be consented and screened for the KIT mutation, as only KIT mutant patients are eligible (and this is estimated to be 10-15% of this patient population). An interim analysis by the Independent Data Monitoring Committee will be done after 9 patients have ...

In this study human tissue of the respiratory tract was examined retrospectively. It was extremely difficult to collect an adequate number of cases who had died an acute death since necroscopic examination in these cases is rare. The data presented support the findings of other investigators who described DCs in human lung tissue and, for the first time, yield information on the initial occurrence and frequency of mature DCs in the human tracheal mucosa.. Animal data suggest an increase in bone marrow progenitor cells of DC and the immigration of these cells into different lung compartments.26 27 Since it has been shown that the number of DCs in the respiratory mucosa increases faster than neutrophil granulocytes after bacterial stimulation, local stimulation and ongoing proliferation might also be involved.28 Interestingly, our data are in line with recent findings in very young mice in whom few DCs were found in the airways.

WFDC2/HE4 encodes a poorly characterised secretory protein that shares structural similarity to the multifunctional host defence protein, SLPI, through possession of two conserved Whey Acidic Protein/four disulphide-core (WFDC) domains. Like SLPI, WFDC2 is expressed in multiple epithelia within the respiratory tract and although its function remains unresolved, recent evidence supports its role as an antiproteinase. We have previously shown that it is over-expressed in lung diseases characterised by abnormalities of protease/antiprotease balance, including cystic fibrosis. Nothing is known about the distribution of WFDC2 in the mouse. In this study we have systematically localized the protein in normal adult mice as well in a number of mouse models characterised by epithelial remodelling. Strong WFDC2 staining is seen throughout the airway epithelium from the trachea down to the smallest airways. Staining is also seen in tracheal submucosal glands. No staining is seen in the peripheral lung. ...

SJS targets the skin and the mucous membranes. Mucous membranes are found all over the body as they line the cavities or passages inside the body, such as the lungs, mouth, nostrils, ears, digestive tract, anus and genitalia. They are also adjacent to the skin. SJS can be a very grave condition because it causes the skin and mucous membranes to become inflamed. The inflammation would quickly aggravate and damage not only the mucous membranes but the major organs of the body as well.. Stevens Johnson Syndrome is brought forth when the body negatively reacts to certain drugs. Under normal conditions, the body metabolizes the chemicals from the medicine the same way as the digestive system digests food. However, with SJS, a chemical component of the drug causes a wrong metabolic response by stimulating the body to excrete protein that would severely affect the cells on the outermost skin layer or epidermis. This abnormal immune response weakens the skins integrity, making it susceptible to foreign ...

Two unique forms of cytochrome P-450 (P-450), designated NMa and NMb, were recently isolated in this laboratory from nasal microsomes of rabbits. In the present study, polyclonal antibodies to the purified nasal cytochromes were prepared. Immunochemical analysis with specific rabbit anti-NMa and sheep anti-NMb antibodies indicated that P-450 isozymes identical to or having a high structural homology with NMa are present in both olfactory and respiratory mucosa, as well as in liver, but NMb was detected only in the olfactory mucosa. Neither form was detected in other tissues examined, including brain, esophageal mucosa, heart, intestinal mucosa, kidney, and lung. The specific occurrence of NMb in the olfactory mucosa was further substantiated by the detection and specific inhibition by anti-NMb of the formation of unique NMb-dependent metabolites of testosterone in olfactory microsomes but not in microsomes from liver or respiratory mucosa. Similar experiments with antibodies to previously ...

Lymphocytes expressing a Testosterone levels cell receptor (TCR) composed of Vgamma9 and Vdelta2 stores represent a small small percentage of human being thymocytes. people overlap intensive in their moving repertoire. This type of selection indicates the existence of a monomorphic antigen-presenting molecule that is definitely an subject of current study but continues to be incompletely described. While selection on a monomorphic delivering molecule may appear uncommon, related systems form the alpha dog beta Capital t cell repertoire including the intense good examples of NKT or mucosal-associated invariant Capital t cells (MAIT) and the much less dramatic amplification of general public Vbeta string rearrangements powered by specific MHC substances and connected with level of resistance to virus-like pathogens. Choosing and amplifying general public Capital t cell receptors whether alpha dog beta or gamma delta, are essential methods in developing an anticipatory TCR repertoire. Cell ...

By: Dr. Deborah Moskowitz Many menopausal women experience some form of vaginal dryness or irritation due to the thinning of the vaginal mucosa that typically occurs as hormone levels decline. Severity of symptoms may vary from woman to woman, even if their vaginal mucosa appear similarly affected. Some women experience only occasional discomfort while for…

Our laboratory seeks to understand how T cells integrate diverse local microbial and environmental stimuli at mucosal sites to shape distinct, and dynamic immune processes inhealth and disease. T cells are a key component of host defense against pathogenic infection in barrier mucosal surfaces, which are common sites of microbial entry. Often these potent, anti-pathogenic inflammatory responses need to be tightly regulated to maintain barrier integrity and vital physiologic functions. The mucosal immune system in the female reproductive tract (FRT) has evolved to mount a robust anti-pathogen defense while maintaining tolerance towards an immunologically foreign fetus. Thus, the FRT provides a unique model system to study T cell adaptation to diverse environmental inputs. Our research program is aimed to develop a more complete understanding of the fundamental biology of T cells in the reproductive mucosae.Further, we seek to apply this knowledge to informing improved vaccination strategies, ...

The absorbance power of diosmectite also allows DIONIT to interact with the glycoproteins of the mucous layer covering the gastroduodenal wall, changing their physical characteristics so to form a protective gel against acid hypersecretion and gastrolesive substances. Fibers, thanks to their bifidogenic and lactogenic effects, are able to restore the endogenous microflora balance, thus normalizing intestinal transit.. Ingredients ...

A 67-year-old man presents with diplopia, blurred vision in his left eye, and an intermittent headache, all for around two weeks. Further questioning reveals recurrent left-sided nasal stuffiness with a blood-streaked mucus discharge for around six months. He has refused to obtain medical attention thus far, and it was only today that his family members were able to persuade him to see a doctor. His medical, surgical, and family histories are otherwise unremarkable, and he is not on any medications ...
