What is the primary role of lymphocytes in the immune response?

Lymphocytes play a crucial role in the immune response primarily through their ability to create antibodies. These white blood cells are pivotal in identifying and targeting specific pathogens, such as bacteria and viruses. There are different types of lymphocytes, including B cells and T cells. B cells are directly responsible for the production of antibodies, which are proteins that bind to specific antigens on the surface of pathogens. This binding neutralizes the pathogen and marks it for destruction by other immune cells.

In addition to their antibody-producing role, lymphocytes are also involved in cell-mediated immunity, especially through T cells, which can help directly kill infected host cells or aid other immune cells in the response. Their ability to adapt and remember specific pathogens also contributes to long-lasting immunity after infections or vaccinations.

Other options, while related to the immune system, do not specifically highlight the primary function of lymphocytes. For instance, the function of engulfing pathogens primarily pertains to phagocytes, like macrophages and neutrophils, which actively ingest and destroy foreign invaders. Releasing histamines is an action associated with mast cells and basophils during allergic reactions, playing a role in inflammation rather than the direct immune response mediated by lymphocytes.
