Hi, John. Thanks for that excellent question. I mean, you know, the manufacturing at the end, you know, is, you know, one of the, you know, big differences, you know, that can result in the, in a difference in the outcome. We don't have all the details of, you know, how different programs that have taken CD19 CAR T into the autoimmune space, you know, have been manufactured. But, definitely, you know, we do feel strongly believe that how the cells are prepared, you know, whether the cells are frozen before administration or administered without freezing, all these things together with, you know, the way that the cells are expanded, you know, makes a big difference. Unfortunately, the details are somewhat lacking because, the information are somewhat kept as a proprietary information, but I think that is a very important question.
