BACKGROUND A T-cell-mediated immune response may be responsible for the enteropathy seen in coeliac disease (CD), but it is unclear whether this is initiated in the epithelium or the lamina propria. We studied the site and number of cells expressing mRNA encoding the cytokines interleukin-2 (IL-2),

In coeliac disease, gliadin peptides p56-88, p57-68 and p31-49 have been demonstrated to be involved in the pathogenic damage of the small intestine via their immunogenicity or toxicity to epithelial cells. To try to understand the mechanism of their toxicity, we investigated the effect of synthetic

Oral immunization with gliadin (GLI) can induce immunoglobulin A mesangial deposits (IgA nephropathy [IgAN]) in mice. A role for GLI in human IgAN has been inferred from an association with celiac disease, increased serum anti-GLI IgA in patients with IgAN, and benefit from a gluten-free diet

The downstream cascade of the inflammatory response to gliadin in celiac intestinal mucosa encompasses the early activation of the innate immunity that triggers the adaptive response. Therefore, the in vitro study of the pathogenic mechanism of celiac disease (CD) on enterocytes alone or mucosal T

Identifying antagonist peptides able to inhibit the abnormal immune response triggered by gliadin peptides in celiac disease (CD) is an alternative therapeutic strategy for CD. The aim of this study was to evaluate the antagonist effect of 10mer, a decapeptide (sequence QQPQDAVQPF) from

Celiac disease (CD) is a chronic, immune-mediated disorder of the gut, driven by T cells reacting locally to a distinct antigen, gliadin. Thus, CD offers the opportunity to study the T cell memory response to gliadin and whether gut tropism and T helper cell type 1 (Th1) polarization, which

Celiac disease (CD) is an immune disease triggered by the cereal antigen gliadin, resulting in villous atrophy in the small intestine. Susceptibility to the development of CD is strongly influenced by genes in the major histocompatibility complex, in particular alleles of the DQ genes in the class

Our aim in this study was to determine soluble tumor necrosis factor (TNF)-like weak inducer of apoptosis (sTWEAK) and interleukin-17A (IL-17A) levels in celiac disease, and their association with the gluten diet and autoantibodies. Eighty patients with celiac diagnosis and 80 healthy control

Dietary components may have an important role in maintaining a balanced gut microbiota composition. Celiac disease is an autoimmune enteropathy caused by gliadins, and has been associated with a reduced proportion of Bifidobacterium in gut microbiota. This study evaluates the influence of

Gliadin, a component of wheat gluten known to be an important factor in the etiology of celiac disease, is related to several other diseases through its enhancing effect on intestinal paracellular permeability. We investigated the significance of gliadin in non-steroidal anti-inflammatory drug

Coeliac disease (CD) is a very common food-sensitive enteropathy, which is triggered by gluten ingestion and is mediated by CD4(+) T cells. In addition, alterations in the intestinal microbiota that is normally involved in the homeostasis of GALT (gut-associated lymphoid tissue) seem to play a role

The autoimmune enteropathy, coeliac disease (CD), is triggered by ingestion of gluten-containing grains. We recently reported that the chemokine receptor CXCR3 serves as a receptor for specific gliadin peptides that cause zonulin release and subsequent increase in intestinal permeability. To explore

Celiac disease (CD) is a chronic enteropathy triggered by intake of gliadin, the toxic component of gluten. This study aims at evaluating the capacity of different Bifidobacterium strains to counteract the inflammatory effects of gliadin-derived peptides in intestinal epithelial (Caco-2) cells. A

Wheat gliadin is the triggering agent in coeliac disease. In this study, we documented that proteolytic fragments of gliadin, in contrast to other food antigens, induced interleukin (IL)-8 and tumour necrosis factor-alpha (TNF-alpha) production and significantly increased interferon

In this study, we have developed a type B gelatin nanoparticle based siRNA delivery system for silencing of intestinal transglutaminase-2 (TG2) and interleukin-15 (IL-15) genes in cultured human intestinal epithelial cells (Caco-2) and murine alveolar macrophage cells (J774A.1). Small interfering
