text: Yo, check it out, here's the deal
  I'ma break it down, keepin' it real
  The causes of inflammation, let me explain
  It's them persistent pathogens and irritatin' materials, man, they're a pain
  
  When you inhale carbon nanotubes, listen up, y'all
  Epithelioid granulomas form, that's the call
  Fibrosis in the lungs, interstitial reaction
  It's a pathological response, causing some traction
  
  In the mesothelium, it's a similar sight
  High aspect ratio nanomaterials takin' flight
  Asbestos fibers, they got that power
  Inject 'em intraperitoneal, they cause a shower
  
  Some engineered nanomaterials, they be playin' the same game
  Actin' like asbestos, it's a cause for some shame
  Lungs and mesothelium, they feel the effect
  Potential health risks, yo, we gotta protect
  
  Our hypothesis is this, listen close, my friend
  In 3D cultures, nonadherent macrophages will descend
  Epithelioid granulomas, they gonna arise
  High aspect ratio nanomaterials, nothin' but surprise
