A judge at a dog show saw a young girl watching from the sidelines.
The girl had autism, and she'd brought her stuffed animal.
So the judge stopped, walked over to her, and asked if she wanted to show her dog, just like the others.
This is what happened.

Many questions unanswered from the FDA report:
Colleagues I've consulted with are very surprised by this as we haven't seen. Questions:
-what was the clinical status of the patients in terms of immunosuppression, prior therapy, conditioning chemotherapy,
Woman on left and right are the same person. SLE before and after CD19 CAR-T treatment. 🤯
Due to wax and wane in SLE, it has been hard to prove drugs work. Much easier when you cure patients! No relapses for 8 patients 4-29 months followup.

Antibody levels are easy to measure, T cell responses are not. Which is why Ab titers get the vast amount of attention, which does not equal relative importance.

What she's describing is more like a light dimmer than an on-off switch.
