Which immune cells are primarily involved in the production of antibodies?

The production of antibodies is primarily the responsibility of B cells, which are a type of lymphocyte. When B cells encounter an antigen, they undergo a process of activation and differentiation. Upon activation, they can transform into plasma cells, which are specialized to produce and secrete antibodies that are specific to that antigen. These antibodies play a critical role in the immune response by identifying and neutralizing pathogens such as bacteria and viruses.

While T cells, macrophages, and neutrophils are all important components of the immune system, they have different roles. T cells are primarily involved in cell-mediated immunity and can help activate B cells, but they do not produce antibodies directly. Macrophages act as phagocytes, engulfing and digesting cellular debris and pathogens. Neutrophils are also phagocytic cells, primarily involved in the acute inflammatory response and in responding to infections. Therefore, the primary role of antibody production lies distinctly with B cells.
