yeah and and it's it's beyond antigen delivery for just phagocytosis or education it's also for conservation of that tissue niche or resident memory as well marion

yeah i mean i think um we don't see cells go completely away when antigen is not there.

But it's sort of this waxing and waning phenomenon, I think, like with the tertiary lymphoid structures.

I think after response, they do shrink down again, and we can see They get smaller.

But if you have another exposure, they can get bigger again pretty quickly.

So it's almost like a lymph node.

You know, you can rest down but then expand again.

And so what have we learned?
