Antigen requirements for induction of B-memory cells: studies with dinitrophenyl coupled to T-dependent and T-independent carriers
H Braley-Mullen
Mice were primed with dinitrophenyl (DNP) (trinitrophenyl, TNP) coupled to
thymus-independent (TI) or thymus-dependent (TD) carriers. B cells from
these mice were transferred to irradiated recipients with T cells from
keyhole limpet hemocyanin (KLH)-primed mice. After secondary immunization
with DNP-KLH a significant DNP-specific IgG memory response was produced
only by mice which received B cells which had been primed with TD antigens.
TI antigens were unable to induce differentiation of B-cell precursors to
IgG producing memory B cells but they did not suppress the induction of
B-memory cells by TD antigens. The results indicate that TI antigens fail
to activate a cell type which is required for the induction of memory B
cells.
