Keywords: celiac disease, exosome and immune modulation, microarray analysis, pathogenesis, transcription factors. Impairment of protein trafficking by direct interaction of gliadin peptides with actin. Gut —8. This analysis is based on the assumption that the similarity of gene expression profiles within a given cluster is suggestive of a similar regulation. Conti Bellocchi 1Giuseppina C. After RNA purification and cDNA synthesis, each sample underwent a microarray screen on a whole-transcriptome scale, and the hybridization results were visualized by hierarchical clustering. Both heterodimers are expressed on antigen-presenting cells and are responsible for the high affinity to gluten peptides and their efficient presentation to T-cells 7. Concordance, disease progression and heritability of celiac disease in Italian twins. Figure 6presenting the heatmap analysis performed on the KEGG pathways, summarizes all the findings described above. For the same genes, the relative expressions vs.

Curr Gastroenterol Rep. Table 2 reports the functional annotation of these genes, and specifically the KEGG pathways resulting significantly enriched among genes belonging to cluster 1.
On one hand, this has the potential of modifying the gene expression picture of acceptor cells, where mRNA incorporated into exosomes may be translated and microRNA exert their regulatory role Figure 4.
The p -value was calculated for the pathways associated with DEG of the various clusters, against the null hypothesis that the enrichment for a particular pathway is random. After RNA purification and cDNA synthesis, each sample underwent a microarray screen on a whole-transcriptome scale, and the hybridization results were visualized by hierarchical clustering. No use, distribution or reproduction is permitted which does not comply with these terms.

|Nature — However, epidemiological data suggest that further predisposing loci might exist Supplementary Table 2 reports the probes for which the log 2 of the ratio vs.
Furthermore, microarray technology still appears a powerful tool for investigating new therapeutic targets, and circulating mononuclear cells were confirmed to be an essential source of information on mucosal immunity in celiac patients. This suggests that in active CD there is a pattern similar to healthy controls and that this pattern is then shut down following the GFD. A 10 mL sample of whole peripheral blood was drawn from each subject at the Gastroenterology Unit, Policlinico G.
These data are confirmed by the heatmap analysis shown in Figure 4.

A further well-represented class represents genes encoding coagulation factors, including the subunits of the heterodimeric von Willebrandt factor. No intermix was observed between the family members and the external controls. Immunogenetic pathogenesis of celiac disease and non-celiac gluten sensitivity.
The sharing of a common household environment and a partially overlapping genetic background seem to shape the overall PBMC gene expression more than the CD status.
As above, nearly all of the genes result down-regulated at comparable levels in all cases.

|Indeed, one member of the family, namely the father, died from a heart attack a few months later being enrolled in this study, the mother developed a B-cell lymphoma localized in the central nervous system, while the clinical findings of the others especially the daughters meanwhile have probably evolved and are no longer similar to what we have pictured through the microarray analysis presented here.
Am J Hum Genet. The demographic and clinical features of the eight total patients and controls are listed in Table 1.
PubMed Abstract Google Scholar. To our knowledge, a comparable cohort of patients has never been addressed and analyzed to define the PBMC gene expression, and this represent a novelty that this study brings to the literature, despite its limitations. The two daughters cc3 and cc4 are indicated as healthy-related H-r1 and H-r2.
