After decades of successful clinical use, the exact molecular mechanisms by which the anti-resorptive bisphosphonate drugs (BPs) exert their effects are now being revealed. In addition to their anti-resorptive effects, it is now apparent that nitrogen-containing BPs (N-BPs) have immunomodulatory properties. Specifically, these drugs activate immune cells called gamma, delta T lymphocytes. In this chapter we discuss the mechanism of gamma, delta T cell activation by N-BPs and propose that N-BPs may provide a safe and effective means for manipulating gamma,delta T cell activity in future immunotherapeutic approaches.
