text: Yo, check it out, here's the scientific scoop,
  We assessed class II antigens on intestinal epithelial cells, whoop!
  Using avidinbiotin-peroxidase technique, oh so slick,
  HLA-DR be reppin' mostly in the small bowel, quick!
  
  But hold up, in the colon, it's a bit diminished,
  Still there, but the expression ain't fully finished.
  HLA-DP staining, a little less in sight,
  And as for HLA-DQ, it's nowhere in our sight.
  
  In inflammatory bowel disease, things took a turn,
  Both HLA-DR and HLA-DP started to churn.
  Their expression increased, but HLA-DQ stayed away,
  Seems like a defect, those cells couldn't convey.
  
  Now let's talk 'bout T84, a cell line so fly,
  Treated with interferon gamma, oh my, oh my!
  HLA-DQ and HLA-DP, they didn't show,
  But HLA-DR was present, yo, don't you know?
  
  We checked the RNAs too, all three subclasses in view,
  HLA-D was detectable, posttranscriptional issue, true.
  Intestinal epithelium got some defects, it seems,
  Explaining why they're unique as antigen-presenting machines.
  
  So there you have it, the science rap I spit,
  Expressing class II antigens, no need to quit.
  Now you know the deal with intestinal epithelial cells,
  They got their own style as antigen-presenting rebels!
