So I guess a couple of things. And I will say with respect to dose, again, there's a lot of literature and obviously clinical experience with NK cells versus T cells. And let's just stick in the lymphoma space because it's the easiest to compare and contrast. In the lymphoma space, obviously, with CAR T cells, in the approved CAR T cells, we've seen doses that are fairly modest compared to an NK cell. I mean, we've seen doses in the 100 million to 200 million range. Single-dose 100 million to 200 million cells with YESCARTA is the recommended dose, is the dose that's used today. I mean, that's exceptionally low compared to NK cell and the history of donor-derived NK cell. If you look at the history of donor-derived NK cell therapy and you go back and you look at the history, my gosh, people are giving not 900 million cells, they're giving like 5 billion, 6 billion, 7 billion, 8 billion cells. So back to Daina's question, I mean, the history of donor-derived NK cell therapy in order to try and drive even modest efficacy, folks have been delivering a multiple of the NK cell compartment that actually just exists within your body which obviously, now when we've always said and others in the industry will say the same thing, if you really want to make an NK cell efficacious, you're going to have to engineer in functional elements. And I think with those engineering in functional elements, whether it be a CAR or CD16 receptor or what have you, I do think you'll see dose levels of NK cells, lower dose levels of NK cells be more efficacious but clearly, they are going to be at dose levels I think that are higher than T cells. And I think that gets back to a little bit of the nature of a T versus an NK. When a T cell gets activated, it is quite capable of undergoing significant expansion and proliferation and they do persist longer compared to an NK cell which is not going to significantly expand as a T cell would and it's nowhere it is not going to functionally persist as long as a T cell. So I think we've always believed and I think it's playing out that the NK cell doses and schedules will be different than what you have typically seen with T cells. The good news, I would say, from -- with respect to the NK cell community, while it may require higher doses, while it may require multiple doses, safety profile I still think is significantly differentiated compared to a T cell.
