title: Comparison of expression profiles induced by dust mite in airway epithelia reveals a common pathway.
abstract: BACKGROUND
  Airway epithelial cells have shown to be active participants in the defense against pathogens by producing signaling and other regulatory molecules in response to the encounter.
  
  
  METHODS
  In previous manuscripts, we have studied the effect of house dust mite (HDM) extract on both an epithelial cell-line (H292) and primary nasal epithelial cell. When we compare these responses we conclude that the H292 cells more closely resemble nasal epithelium of healthy controls (share 107 probe-sets) than of allergic individuals (share 17 probe-sets).
  
  
  RESULTS
  Interestingly, probably because of an absent intraindividual variation between samples, more probe-sets (8280) change expression significantly in H292 than in either healthy (555) or allergic (401) epithelium.
  
  
  CONCLUSIONS
  A direct comparison of all the responses in these epithelial cells reveals a core-response to HDM of just 29 genes. These genes (CCL20, IL-8, CXCL2, CXCL1, IL-1B, AREG, TNFAIP3, HBEGF, PTGS2, BMP2, LDLR, PLAUR, PLAU, NFKB2, NFKB1, JUN, ATF3, EGR1, NPC1, TICAM1, EPHA2, CTGF, DUSP1, SPRY1, TLR-3, complement factor C3, IVNS1ABP, SerpinB3, and PSAT1) have described links with allergy or inflammation and may even describe the well-established relationship between viral infections and allergic exacerbations or allergy development.
