text: Yo, check it out, listen up, here's the scoop,
  Talkin' 'bout functional high-affinity interleukin-2 receptors, that's the truth.
  IL-2R, three transmembrane proteins in the mix,
  IL-2R alpha, beta, and gamma, that's the fix.
  
  We did some research on them immature mouse thymocytes,
  Investigated IL-2R alpha and beta genes, don't you see?
  Previous work showed IL-2R alpha briefly on their surface,
  When these cells differentiate, that's the purpose.
  
  Stimulated IL-2R alpha+ and IL-2R alpha- cells, that's the plan,
  Phorbol 12-myristate 13-acetate and calcium ionophore in hand.
  Synthesis of IL-2R alpha and IL-2R beta mRNA, it's a thrill,
  Autocrine stimulation by IL-2, that's the skill.
  
  IL-1 and IL-2, they synergize real tight,
  120-fold increase in IL-2R alpha mRNA, outta sight.
  14-fold increase in IL-2R beta mRNA levels, that's the game,
  Stimulated cells got both transcripts, ain't that insane?
  
  But hold up, these interleukins don't make 'em mature,
  No differentiation to be found, that's for sure.
  IL-2, it's the boss in regulating IL-2R expression,
  In them normal immature thymocytes, it's the obsession.
  
  We think this interleukin response is part of a plan,
  A homeostatic mechanism, boostin' production, understand?
  When stress hits hard, increase them thymocytes, that's the key,
  IL-2 playin' a major role, keepin' things in harmony, you see?
