T/F Natural killer cells need to see an antigen before they can kill it.
Ans: False, they "naturally" know how to fight things. This is why they make up part of the
innate immune system.
What do B cells do?
Ans: Turn into plasma cells which produce antibodies, or turn into memory cells which
remember antigen information. They also serve as antigen presenting cells.
Where do antibodies come from?
