B lymphocytes relate to which adaptive immunity?

B lymphocytes drive the humoral arm of adaptive immunity. They mature in the bone marrow and, when activated by a specific antigen (often with help from helper T cells), differentiate into plasma cells that secrete antibodies into the blood and other body fluids. These antibodies neutralize pathogens, mark them for destruction through opsonization, and can activate the complement system, helping to clear infections. Memory B cells formed during this response provide long-lasting protection by responding rapidly to future encounters with the same antigen. In contrast, cell-mediated immunity is mainly T cell–driven and targets infected or abnormal host cells, while innate immunity is non-specific and immediate. Autoimmune processes involve immune responses against self, not a distinct adaptive pathway like humoral immunity.
