Antibody responses are initiated in lymph nodes close to the site of initial infection (so - called draining lymph nodes, or DLNs), where antigen - presenting cells, helper T cells, and antibody - producing B cells migrate to and interact to form so - called «germinal centers» and produce a highly specific antibody response.
