Recently, significant progress had been made in understanding the T-B
lymphocyte interactions that control humoral immunity. This review hig
hlights experiments that demonstrate a central role for interactions b
etween T-cell-B-cell-activating molecule (CD40 ligand) expressed on T
cells and CD40 on B cells in B-cell activation and immunoglobulin isot
ype switching, both in vitro and in vivo.
