Natural killer (NK) cells are lymphocytes, immune cells which have a powerful arsenal of cytotoxic weaponry that they can use against tumors.

Unfortunately, tumors protect themselves using a protective microenvironment that shields them from attack from NK cells. This microenvironment promotes tumor growth and survival and has an immunosuppressive effect that blunts the attempts of NK cells to infiltrate the tumor and destroy it. That was until now and this new discovery.
