T gamma delta as tumor cell killers

il-15 convert Tgamma delta cells into nk-like cells which specialize in fighting cancer.

Hypothesis:

The delta one version focuses on early cancer wearing nkp44 and nkp30 while the delta two T cells with DNAM-1 focus on late cancers specifically the metastasized cancers wearing cd155.

Tgamma delta and cancer, they act with NK and alone

nkp44 binds the ligands on tumors: mll5 or pdgf-dd (cell cycle ligand and growth factor ligand)

note that in pregnancy NK cells do not have nkp44 or DNAM-1 on them

Not all the Tgammadeltas act like NK
