The present studies were designed to probe the role(s) of T cells in preventing or altering tolerance induction in hapten-specific B cells. This was accomplished by using hapten conjugates of normally immunogenic heterologous carriers to selectively inhibit 2,4-dinitrophenyl (DNP)-primed B cells in adoptive transfer experiments in vivo. The data provide strong indications that one critical role of T-cell participation in humoral responses to antigens is to circumvent the development of a tolerogenic signal that, in the absence of such T-cell function, might otherwise ensue after binding of the antigenic determinants by specific precursor B lymphocytes.
本研究旨在探究T细胞在预防或改变半抗原特异性B细胞耐受诱导中的作用。这是通过在体内过继转移实验中使用通常具有免疫原性的异源载体的半抗原缀合物来选择性抑制经2,4-二硝基苯基(DNP)致敏的B细胞来实现的。数据提供了有力的证据,表明T细胞参与对抗原的体液反应的一个关键作用是规避致耐受性信号的产生,在没有这种T细胞功能的情况下,特异性前体B淋巴细胞结合抗原决定簇后可能会产生这种信号。
