The mammalian immune system is an evolutionary wonder. It's capable of recognizing and destroying cancer cells, and it can deploy armies of antibodies against viruses, bacteria, parasites and fungi.

When this occurs, the body creates aggregates of immune cells—the TLSs—at the diseased tissue site. These ad-hoc immune system outposts boost the immune response locally.
