Tissue Resident Macrophages hang out in the area of initial infection, waiting for “that guy” to show up again.
This is specifically the bit I’m struggling with. How will they know it’s “that guy”?
It’s a bit like saying “We know this criminal uses disguises. We’ve given everyone copies of his mugshot, which they’ve used for target practice. Now if he wanders in wearing a disguise, people will recognise him.”
As I understand it, “hidden” is a relative thing.
I guess this is the answer?
Going back to my analogy, you’re saying his disguises are pretty simple. So he might wear glasses or a fake beard, but he isn’t likely to turn up in a full clown outfit, with multi-coloured hair, make up, and a big red nose.
Thank you so much for taking the time to explain, I really appreciate it.
