pubmed-article:2463306 | pubmed:abstractText | We previously reported that idiotype (Id)-loss, stable somatic variants of a B cell hybrid, 2C3E1, are generated both in vitro and in vivo, after interaction of the Id-positive tumor cells with autologous Id-specific effector T cells. The present investigation was undertaken to elucidate further the nature and functional characteristics of the effector T cells. We report here that the idiotype-specific cells mediating the generation of Id- tumor variants are Thy1+ L3T4+ Lyt-2- cells, which respond to specific idiotypic stimulation by secreting IL-2 in vitro. No IL-2 is secreted in response to unrelated Ig or an Id/Ig-2C3E1 tumor variant. Furthermore, the Id-specific T cells exert strong suppressive effects on the expression of 2C3E1 Ig and the effects can be reversed by blocking the L3T4+ T cells with monoclonal anti-L3T4 antibody in vitro during the initial 3 days of co-culture. After 4 days, the T cell-mediated suppression of the 2C3E1-Id is irreversible. In addition to the in vitro studies we have determined that the administration of anti-L3T4 mAb to mice just before priming with idiotype-bearing tumor cells also abrogates the suppressive effects of the idiotype primed spleen cells on Ig expression of 2C3E1. To study the Id-specific effector T cells in more detail we have generated functional Id-specific L3T4+ T cell lines. These T cell lines have been shown to recapitulate the generation of Id- tumor variants that we observed with Id-primed spleen cells. It is concluded that L3T4+, Id-specific Ts cells are responsible for the generation of somatic variants of the B cell hybrid 2C3E1 and that the induction or selection of these variants progresses from a reversible phase to an irreversible phase. | lld:pubmed |
