gene has been suggested to bind LPP. In our two-locus interaction analysis, the LPP locus and a locus containing KIF13A was one of the 101 interaction pairs. KIF13A is a motor protein, which shuttles vesicles containing AP-1 and the mannnose-6- phosphate receptor. KIF13A was significantly down-regulated in intestinal biopsies from CD patients in our gene expression analysis. SVIL is associated with cell-focal adhesions, which are important for rapidly moving cells such as for example immune cells but also for motility and polarity of intestinal epithelial cells. SVIL mRNA was down-regulated in our gene expression analysis, however, not significant after correction for multiple testing. Another gene present in these networks was the gene encoding for the immune molecule CD40. CD40 has been shown to regulate immune responses to another parasite, Leishmania Major, by shared signaling through p38 MAPK and ERK1/2. CD40 also regulates DUSP expression and activity, which in turn contribute to anti-leishmanial functions. It has been suggested that Leishmania Major inhibits CD40-triggered p38 MAPK signaling as part of an immune evasion strategy. Another overrepresented category from GeneTrail was the extracellular matrix. Also, in the two most significant Ingenuity networks from the 603 marker analyses, ECM molecules and matrix metalloproteinases were included. The ECM represents a major barrier to parasites like amoebas and leishmania. Parasites produce a wide variety of proteases to break down the ECM in order to access essential nutrients and invade host tissue. A different situation when the ECM is degraded is during nutrient deprivation. In this way the ECM can provide energy for starving host cells. Just like gluten, the ECM has an unusually high AZD5363 biological activity proline content. MMPs are enzymes, which break down ECM making proline readily available as a nutritional source. Pandhare and co-workers have shown that energy or nutrient stress activates MMPs as well as the degradation of proline and furthermore demonstrated that, as the levels of glucose decreased to 1 mM and lower in the medium, 333994-00-6 chemical information intracellular proline increased almost 2-fold. If gluten lingering in the intestine conveys a signal of ECM degradation, several other mec
