Which white blood cell type is primarily involved in antibody production and cell-mediated immunity?

Lymphocytes are the white blood cells that handle adaptive immunity. B lymphocytes become plasma cells that secrete antibodies, providing antibody-mediated (humoral) immunity. T lymphocytes carry out cell-mediated immunity: cytotoxic T cells destroy infected or abnormal cells, and helper T cells coordinate and amplify the response, including helping B cells produce antibodies. Other white blood cells have different roles—monocytes/macrophages do phagocytosis, neutrophils are rapid responders to infection, and eosinophils target parasites and participate in allergic responses. So lymphocytes are the ones driving both antibody production and cell-mediated responses.
