Primary Sjögren's syndrome (pSS) is a systemic autoimmune disease marked by dry mouth/dry eye symptoms as a result of the destruction of the salivary and lacrimal glands. Patients with pSS may be at risk for the development of mucosa-associated lymphoid tissue (MALT) lymphoma. Testing of autoantibodies in the oral fluid of patients with pSS or MALT lymphoma using immunoassays may lead to a simple and noninvasive clinical tool for diagnostic or prognostic applications.

Selection for prolificacy in modern pig farming has resulted in increasing litter sizes. Since rearing large litters is challenging, artificial rearing of piglets with a milk replacer is an alternative strategy. It is hypothesized that the development of the piglets' mucosa-associated lymphoid tissues (MALT) is affected by these artificial conditions. Read More

Mucosa-associated lymphoid tissue lymphoma translocation protein 1 (MALT1) is an intracellular cysteine protease (paracaspase) that plays an integral role in innate and adaptive immunity. The phenothiazine mepazine has been shown to inhibit the proteolytic activity of MALT1 and is frequently used to study its biological role. MALT1 has recently been suggested as a therapeutic target in rheumatoid arthritis. Read More

Infection of the human stomach caused by is very common, as the pathogen colonizes more than half of the world's population. It is associated with varied outcomes of infection, such as peptic ulcer disease, gastric ulcers, and mucosa-associated lymphoid tissue lymphoma, and is generally considered a risk factor for the development of gastric adenocarcinoma. Cholesteryl glucosides (CGs) constitute a vital component of the cell wall of and contribute to its pathogenicity and virulence. Read More

Background And Objective: The stomach plays an important role in obesity and obesity-related diabetes; yet, little is known about key pathways in the gastric mucosa associated with obesity and diabetes.

Methods: We performed gene microarray and real time-polymerase chain reaction (RT-PCR) on gut mucosa samples from control subjects (CON), patients with simple obesity (OB), and patients with obesity and comorbid diabetes (OD) (n = 3 per group). Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses were used to predict the functional significance of differentially expressed genes. Read More

Background And Aims: This study aimed to characterise the mucosa-associated microbiota in ileal Crohn's disease (CD) patients and in healthy controls in terms of host genotype and inflammation status.

Methods: The mucosa-associated microbiota of intestinal pinch biopsies from 15 ileal CD patients with mild and moderate disease and from 58 healthy controls were analysed by 16S ribosomal sequencing to determine microbial profile differences between (1) IL23R, NOD2 and ATG16L1 genotypes in healthy subjects, (2) ileal CD patients and control subjects, and (3) inflamed and non-inflamed mucosal tissue in CD patients.

Results: The protective variant of the IL23R gene (rs11209026) significantly impacted the microbial composition in the ileum of healthy subjects and was associated with an increased abundance of phylotypes within the Christensenellaceae family as well as increases in diversity and richness.

Mucosa-associated invariant T (MAIT) cells are unconventional innate-like T cells that recognize microbial riboflavin metabolites presented by the MHC class I-like protein MR1. Human MAIT cells predominantly express the CD8α coreceptor (CD8), with a smaller subset lacking both CD4 and CD8 (double-negative, DN). However, it is unclear if these two MAIT cell subpopulations distinguished by CD8α represent functionally distinct subsets. Read More

Objective: In the 2016 American College of Rheumatology/European League Against Rheumatism classification criteria for primary Sjögren's syndrome (pSS), pre-existing lymphoma is not an exclusion criterion for pSS diagnosis, as in earlier criteria. We aimed to explore whether there are differences between pSS patients with and without pre-existing lymphoma at pSS diagnosis.

Method: Patients with ICD-7-10 codes for Sjögren's syndrome (SS) and a diagnosis of malignant lymphoma before or after SS diagnosis were identified by linking the Swedish Patient Register 1964-2007 with the Cancer Register 1990-2007 (n = 224). Read More

Purpose Of Review: Like the rest of the gastrointestinal tract, the small intestine is colonised by microbes, but how this "microbiome" affects the immune system and digestive functions has largely been overlooked, especially in the "omics" era. Here, we present recent findings that show that the diversity, density and interactions of these microbes in the small intestine can play an important role in the pathogenesis of a number of gastrointestinal and extraintestinal disorders.

Recent Findings: Changes in the small intestinal mucosa-associated microbiota (SI-MAM) have been shown to occur with inflammatory bowel diseases, functional gastrointestinal disorders, metabolic disorders such as obesity and type 2 diabetes. Read More

Inflammatory bowel disease (IBD) is a multifactorial disease which arises as a result of the interaction of genetic, environmental, barrier and microbial factors leading to chronic inflammation in the intestine. Patients with IBD had a higher risk of developing colorectal carcinoma (CRC), of which the subset was classified as colitis-associated cancers. Genetic polymorphism of innate immune receptors had long been considered a major risk factor for IBD, and the mutations were also recently observed in CRC. Read More

Despite the negative results of blocking IL-17 in Crohn's disease (CD) patients, selective modulation of Th17-dependent responses warrants further study. Inhibition of retinoic acid-related orphan receptor gamma (RORγt), the master regulator of the Th17 signature, is currently being explored in inflammatory diseases. Our aim was to determine the effect of a novel oral RORγt antagonist (BI119) in human CD and on an experimental model of intestinal inflammation. Read More

MALT1 is a unique enzyme among this clan because it recognizes the basic amino acid arginine in the P1 pocket. Previous studies carried out with natural amino acids revealed the substrate specificity of the P4-P1 pockets of MALT1 but have provided only limited information about the catalytic preferences of this enzyme.

The MALT1 (Mucosa associated lymphoid tissue lymphoma translocation protein 1) paracaspase couples antigen receptors on lymphocytes to downstream signaling events. Activation of MALT1 is known to involve stimulus-dependent CBM complex formation, that is, the recruitment of BCL10-bound MALT1 to a CARD-Coiled Coil protein. Beyond this canonical, CBM-dependent mechanism of MALT1 activation, recent studies suggest that MALT1 protease activity may be triggered by alternative mechanisms. Read More
