text: Yo, listen up, I got a story to tell
  'Bout them Vγ2Vδ2 cells, they fightin' like hell
  Microbial and tumor immunity, that's their game
  They monitor them pyrophosphate metabolites, no shame
  
  Bisphosphonate treatment, it's the key
  Isoprenoid metabolites, lettin' Vγ2Vδ2 see
  They recognize, they kill, tumors don't stand a chance
  No need for MHC expression or mutations, it's a dance
  
  Clinical trials, over 400 patients, they've seen
  Adoptive immunotherapy with Vγ2Vδ2, a dream
  Few side effects, but partial and complete remissions few
  But we ain't stoppin', we got somethin' new
  
  Checkin' inhibitory receptors, that's the plan
  PD-1, CTLA-4, LAG-3, and TIM-3, a whole clan
  Ex vivo expansion, 14 days in the lab
  Then stimulated by pamidronate-treated tumor cells, grab
  
  PD-1, LAG-3, TIM-3, they show up strong
  When Vγ2Vδ2 gettin' their groove on
  PC-3 prostate cancer cells, they feel the heat
  Co-culture with Vγ2Vδ2, PD-L1 increased, it's sweet
  
  But wait, there's more, we ain't done yet
  Anti-PD-1 mAb treatment, you won't forget
  Immunodeficient NSG mice, PC-3 tumors in sight
  Vγ2Vδ2 with checkpoint blockade, they takin' flight
  
  Tumor volume reduced to zero, in just five weeks
  PD-1 checkpoint blockade, it's what they seek
  Adoptive immunotherapy, gamma-delta style
  Prostate tumors, they can't deny, it's worthwhile
  
  These results, they show the way
  PD-1 checkpoint blockade, a game-changer, I say
  Human γδ T cells, they got the power
  In the fight against prostate tumors, they'll devour
