Ichthyosiform dermatosis is a term referred to a group of disorders that have as their basis a disorder of keratinization (1). These conditions which are present at birth result in a generalized dry, scaly skin without any inflammation. There are several types of ichthyosis based on their clinical presentation and mode of inheritance. The most common types are: ichthyosis vulgaris, X-linked recessive ichthyosis, epidermolytic hyperkeratosis (bullous), lamellar ichthyosis and non-bullous ichthyosiform erythroderma...

BACKGROUND & AIMS: Little is known about the prevalence and burden of undiagnosed celiac disease in individuals younger than 50 years old. We determined the prevalence and morbidity of undiagnosed celiac disease in individuals younger than 50 years in a community. METHODS: We tested sera from 31,255 residents of Olmsted County, Minnesota (younger than 50 years old) without a prior diagnosis of celiac disease assay using an assay for immunoglobulin A (IgA) against tissue transglutaminase (tTG); in subjects with positive test results, celiac disease was confirmed using an assay for endomysial IgA...

OBJECTIVES: Limited pediatric data exist examining the trend and predictors of anti-tissue transglutaminase (atTG) normalization over time in children with celiac disease (CD). We aimed to evaluate time to normalization of atTG in children after CD diagnosis, and to assess for independent predictors impacting this duration. METHODS: A retrospective chart review was completed in pediatric CD patients diagnosed from 2007 to 2014 at the Stollery Children's Hospital Celiac Clinic (Edmonton, Alberta)...

Astrocytes play numerous complex roles that support and facilitate the function of neurons. Further, when there is an injury to the central nervous system (CNS) they can both facilitate or ameliorate functional recovery depending on the location and severity of the injury. When a CNS injury is relatively severe a glial scar is formed, which is primarily composed of astrocytes. The glial scar can be both beneficial, by limiting inflammation, and detrimental, by preventing neuronal projections, to functional recovery...

Natural biomaterials, such as chitosan and collagen, are useful for biomedical applications because they are biocompatible, mechanically robust and biodegradable, but it is difficult to rapidly and tightly bond them to living tissues. Here, we demonstrate that the microbial enzyme transglutaminase (mTG) can be used to rapidly (< 5 min) bond chitosan and collagen biomaterials to the surfaces of hepatic, cardiac and dermal tissues, as well as to functionalized polydimethylsiloxane (PDMS) materials that are used in medical products...

Celiac disease is usually diagnosed by demonstrating gluten enteropathy in small bowel biopsy. Celiac specific antibodies are used as an initial screening test. The goal of this study is to test the relationship of the anti-tTG titer and severity of histological changes in Jordanian children with celiac disease. Method. The medical records of 81 children who had elevated anti-tTG titer and had duodenal biopsies available were retrospectively reviewed. Result. Assessing the association of anti-tTG titer with duodenal histopathological changes, 94% of those with high anti-tTG titer (≥180 U/mL) had histological evidence of celiac disease...

Uncombable hair syndrome (UHS), also known as "spun glass hair syndrome," "pili trianguli et canaliculi," or "cheveux incoiffables" is a rare anomaly of the hair shaft that occurs in children and improves with age. UHS is characterized by dry, frizzy, spangly, and often fair hair that is resistant to being combed flat. Until now, both simplex and familial UHS-affected case subjects with autosomal-dominant as well as -recessive inheritance have been reported. However, none of these case subjects were linked to a molecular genetic cause...

Deposition of amyloid-beta (Aβ) peptides has been shown to induce the release of inflammatory factors by activated microglia and brain infiltrating monocytes/macrophages. Interestingly, the enzyme transglutaminase 2 (TG2) has been shown to play a key role in neuroinflammation and regulation of transcription factors involved in immunomodulation. In this study, we aimed to better elucidate the mechanisms underlying TG2 involvement in the pro-inflammatory signaling pathway activated by fibrillar Aβ1-42 in THP-1 monocytes...

Transglutaminases (TGs) are a family of enzymes that catalyse the formation of isopeptide bonds between the γ-carboxamide groups of glutamine residues and the ε-amino groups of lysine residues leading to cross-linking reactions among proteins. Four members, TG1, TG2, TG3, and TG5, of the nine mammalian enzymes are expressed in the skin. TG1, TG3 and TG5 crosslinking properties are fundamental for cornified envelope assembly. In contrast, the role of TG2 in keratinization has never been studied at biochemical level in vivo...

Fractioning and/or preheating treatment on the rheological properties of myofibrillar protein (MP) gels induced by microbial transglutaminase (MTG) has been reported that they may improve the functional properties. However, the optimum condition was varied depending on the experimental factors. This study was to evaluate the effect of red bean protein isolate (RBPI) on the rheological properties of MP gels mediated by MTG as affected by modifications (fractioning: 7S-globulin of RBPI and/or preheat treatment (pre-heating; 95℃/30 min): pre-heating RBPI or pre-heating/7S-globulin)...

Transglutaminase is an enzyme family responsible for post-translational modification such as protein cross-linking and the attachment of primary amine and/or deamidation of glutamine-residue in proteins. Medaka (Oryzias latipes), a recently established model fish, has similar functional proteins to those characterized in mammals. Previously, we found the apparent orthologues that correspond to human transglutaminases in medaka. In this study, regarding the medaka orthologue of human tissue-type transglutaminase (OlTGT), recombinant protein was expressed in an active form in bacteria cultured at low temperature...

BACKGROUND: Dermatitis herpetiformis (DH) is characterized by the presence of anti-tissue transglutaminase (tTG) IgA antibodies in patient sera. In 2002, anti-epidermal transglutaminase (eTG) antibodies have been identified in DH patients. Nowadays, their role is still controversial. AIM: To evaluate any association between presence/absence of anti-eTG antibodies and cutaneous manifestations during the follow-up. METHODS: Anti-eTG and anti-tTG antibodies from 13 patients on gluten-free diet (GFD) were studied during follow-up on ELISA...

The rheological behavior, gel properties and nanostructure of complex modified fish scales gelatin (FSG) by pectin and microbial transglutaminase (MTGase) were investigated. The findings suggested that MTGase and pectin have positive effect on the gelation point, melting point, apparent viscosity and gel properties of FSG. The highest values of gel strength and melting temperature could be observed at 0.8% (w/v) pectin. Nevertheless, at highest pectin concentration (1.6% w/v), the gel strength and melting temperature of complex modified gelatin gels decreased...

BACKGROUND: Alopecia areata (AA) is a noncicatricial (nonscarring) alopecia. The association between AA and celiac disease (CD) is debatable. Several studies declare the relationship between AA and CD as measurement of celiac autoantibodies (anti-gliadin IgA and anti-gliadin IgG), but a few studies consider anti-tissue transglutaminase IgA. The aim of this study was to evaluate the frequency distribution of celiac autoantibodies (all of them) in patients with AA compared with controls...

Leukocyte infiltration into the central nervous system (CNS) is a key pathological feature in multiple sclerosis (MS) and the MS animal model experimental autoimmune encephalomyelitis (EAE). Recently, preventing leukocyte influx into the CNS of MS patients is the main target of MS therapies and insight into cell behaviour in the circulation is needed for further elucidation of such therapies. In this study, we aimed at in vivo visualization of monocytes in a time-dependent manner during EAE. Using intravital two-photon microscopy (IVM), we imaged CX3CR1(gfp/gfp) mice during EAE, visualizing CX3CR1-GFP(+) monocytes and their dynamics in the spinal cord vasculature...

Celiac disease is a chronic inflammatory autoimmune enteropathy based disorder that is triggered by the ingestion of gluten in genetically susceptible individuals. The global prevalence of 1% to 2% represents only the tip of the iceberg. The diagnosis is confirmed by positive specific antibody, anti-transglutaminase or anti-endomysium, specific lesions of the small intestine and a response to strict gluten-free diet. The diagnosis is difficult and often delayed because the clinical variability is very large, ranging from digestive clinical presentation "classic" to "atypical" symptoms, often extra-intestinal, that are sometimes attributed to a concomitant disease or a complication...
