Which cells are primarily associated with adaptive immunity?

Adaptive immunity relies on specialized lymphocytes that recognize specific antigens, with the primary players being B cells and T cells. B cells respond to pathogens by becoming plasma cells that secrete antibodies, which neutralize invaders and mark them for destruction. T cells come in several forms, including helper T cells that coordinate the immune response and cytotoxic T cells that kill infected cells. Both lineages derive from lymphoid precursors and create diverse, antigen-specific receptors, enabling targeted responses and memory upon re-exposure. Macrophages are part of the innate system, providing early defense and also presenting antigens to T cells, but they are not the main agents of adaptive specificity. NK cells are also innate lymphocytes and do not generate the antigen-specific receptors characteristic of B and T cells. Erythrocytes (red blood cells) do not participate in immune recognition.
