Lymphocytes

B cells play a large role in the humoral immune response. In humans, B cells are produced and mature in the bone marrow. The human body produces several types of B cells. Each B cell is unique, with a distinctive cell surface receptor protein that binds to only one particular antigen. Once B cells encounter their antigen and receive a cy-tokine signal from helper T cells, they can further differentiate into one of two cells, plasma B cells or memory B cells. Plasma B cells secrete antibodies that induce the destruction of target antigens through a process known as opsonization. Memory B cells play an important role in long-term immunity. Once formed to a specific antigen, memory B cells are capable of rapidly responding to subsequent exposures to their target antigen.
