= B cell
An immune-cell lineage associated with <antibody> responses. Lineage-specific proliferation and clonal expansion should be distinguished from changes in a mixed sample.
A <B cell> displays an antigen-binding <receptor> and can differentiate into an antibody-secreting <plasma cell> or a memory <biological population>. Activation selects and expands particular binding specificities, allowing a rare lineage to contribute substantially to an <immune response>. <Immunobiology: The Immune System in Health and Disease, 5th edition by Charles A.
