Aminobisphosphonate-activated gammadelta T cells in immunotherapy of cancer: doubts no more.
BACKGROUND
Activated V gamma 9 V delta 2 T cells are able to kill most tumour cells because of recognition by T cell receptor and natural killer receptors.


OBJECTIVE
We discuss the possibility that the intentional activation of gammadelta T cells in vivo by aminobisphosphonates may represent a promising target for the design of novel and highly innovative immunotherapy in cancer patients.


METHODS
The antitumoral effects of gammadelta T cells both in vitro and in vivo have been demonstrated suggesting a new therapeutic approach for translation into the clinical setting.


CONCLUSIONS
V gamma 9 V delta 2 T lymphocytes represent a particularly interesting target for immunotherapeutic protocols based on N-aminobisphosphonate administration and several Phase I-II trials are ongoing investigating the activity of zoledronic acid plus IL-2 in solid tumours.
