SLAMF7

Signaling lymphocytic activation molecule family member 7 (SLAMF7), an activating receptor expressed on natural killer (NK) cells, can stimulate innate and adaptive immunity.

  • SLAMF7 is an activating receptor expressed on virtually all NK cells and other immune cell subsets1
    • SLAMF7 is not expressed on solid tissues or hematopoietic stem cells2
  • Engagement of SLAMF7 activates NK cells, the rapid responders of the immune system and the body’s first line of defense against cancer3,4
  • NK cells directly kill target cells, yet spare normal cells5
