摘要:: Cellular interactions involved in the T cell-dependent activation of B cells were analyzed by using lines and clones of helper T cells specific for determinants expressed on the B cell surface. Activation of male antigen-, M locus-, and H-2-specific T cells was shown to support polyclonal Ig production by a population of B cells that did not require T-cell-B-cell interaction for induction/amplification. However, these T cells alone did not activate gradient-purified small (resting) B cells. The activation of small B cells was shown to require not only a signal derived through an antigen-specific T-helper cell-B cell interaction but in addition a second signal that could be provided by anti-Ig antibodies.
