title: Maturation of B-cell clones.
abstract: The maturation of B-cells was investigated in adoptive transfers and splenic foci. Anti-idiotypic antigens were used to identify clones responding to PC and dextran. A distinct temporal hierarchy of responsiveness could be observed in which the anti-TNP response appears first, followed by anti-dextran and anti-PC. Tolerance induction and anti-idiotype suppression were used as markers for maturing B-cells responding in splenic foci. A differential susceptibility to these manipulations establishes two types of progenitor cells. A scheme for the maturational steps of B-cells is proposed.
