Which cells are responsible for the production of antibodies?

The production of antibodies is primarily the function of B lymphocytes, also known as B cells. When B cells are activated, often by encountering a specific antigen, they undergo differentiation into plasma cells. These plasma cells are responsible for synthesizing and secreting antibodies that target specific pathogens or foreign substances in the body.

B cells form an essential part of the adaptive immune response, providing a mechanism for long-lasting immunity. Once they have encountered a pathogen, some B cells become memory B cells, which remain in the body and respond more swiftly and effectively if the same pathogen is encountered again in the future.

Other cell types mentioned, such as macrophages, play a different role in the immune response by engulfing and digesting pathogens. Memory T cells are involved in cell-mediated immunity and do not produce antibodies. Basophils are primarily associated with inflammatory responses and allergic reactions but do not produce antibodies either. Hence, the unique role of B lymphocytes in antibody production distinguishes them as the correct answer.
