Setting it Straight: In the node - Part 1
Having discussed the interactions that allow naïve lymphocytes to enter the lymph nodes (#39), how the lymph nodes function in a broadly biological sense and what happens when effector and memory T cells and B cells exit, then head off around the body (#40) it’s time to backtrack a little and summarise what happens in the node.
