mA Methylated Long Noncoding RNA LOC339803 Regulates Intestinal Inflammatory Response.

Cytokine mediated sustained inflammation increases the risk to develop different complex chronic inflammatory diseases, but the implicated mechanisms remain unclear. Increasing evidence shows that long noncoding RNAs (lncRNAs) play key roles in the pathogenesis of inflammatory disorders, while inflammation associated variants are described to affect their function or essential RNA modifications as N-methyladenosine (mA) methylation, increasing predisposition to inflammatory diseases. Here, the functional implication of the intestinal inflammation associated lncRNA LOC339803 in the production of cytokines by intestinal epithelial cells is described.

Preparation of pepsin trypsin digested gliadin for stimulation experiments.

Celiac disease (CD) is a complex immune disorder of the intestine that developes in genetically susceptible individuals. CD develops as an intolerance to ingested gluten proteins (gliadins, secalins, hordeins and avenins), being gliadin one of the most immunogenic. Here we present a protocol for the preparation of digested gliadin for laboratory use, a fundamental axis for in vitro and in vivo stimulation studies related to celiac disease research.
