What side effects are being seen with NK cell therapy?

What side effects are being seen with NK cell therapy? In general, the side effects of NK cells are actually, they're pretty well tolerated. We haven't seen very much graft versus host disease from these off the shelf products. There can be some infusion reactions and that's true for anything that's a little bit foreign. If they've been infused and sometimes stimulated with, for example, IL-2, which is interleukin-2, which might help boost the NK cell, sometimes patients have reactions to those as well. As far as things like cytokine release syndrome, this is something that you'd see more with the engineered or more specific NK cell products. Again, has not been too scary as far as things like considering side effects from cellular therapy. I really think this might be a good way to go for off the shelf safe therapy that might be effective, at least to tide patients over to get a more effective therapy or to make their therapy last longer.
