text: Yo, check it out, here's the scoop
  We got some genes, immunity-related group
  TNF family members, chemokine receptors too
  Transcription factors, CD4+ CD3- crew
  
  We sorted these cells, phenotype in mind
  Compared gene expression, a unique find
  Distinct from dendritic cells, that's for sure
  Plasmacytoid dendritic cells, T cells, B cells, no allure
  
  NK cells, they ain't the same
  But CD4+ CD3- cells, they share the name
  Embryonic and neonatal tissues in line
  Similar genetic fingerprint, that's the sign
  
  But hold up, there's a difference to see
  Only adult populations express OX40L and CD30L, can't you see?
  IL-7 signals, they regulate CD30L's game
  That's what we reported, ain't it a shame?
  
  In this study, neonatal and adult cells shine
  They both express death receptor 3, it's prime
  TL1A, the ligand, steps in the scene
  Up-regulates OX40L, neonatal cells sheen
  
  And here's the kicker, the proof we present
  Neonatal cells, they adapt, they reinvent
  After transfer to adult, they rise above
  Up-regulate CD30L and OX40L, that's love
