A mechanism responsible for the induction of NP-specific first order (inducer) suppressor cells (TS1) is described. TS1 cells are induced by i.v. administration of hapten-coupled splenic cells. Their activity is assessed by the adoptive transfer of NP-specific suppression during the afferent phase of the contact sensitivity response. NP-coupled firmly adherent, FcR+, I-A-bearing macrophages induce TS1. The antigen-presenting cells required for TS1 induction lack the Thy-1 and Lyt-1 markers, and are resistant to 500 R irradiation and to cyclophosphamide treatment. NP-coupled dendritic cells fail to induce TS1 activity. The induction of TS1 cells is genetically restricted by genes that map in the I-J region of the H-2 complex. The NP-coupled antigen-presenting cells must share at least one I-J allele with the TS1 donor for effective induction of TS1 activity. To minimize allogeneic effects in these studies, the activity of the TS1 population was assessed by adoptive transfer into syngeneic recipients. The present results are compared with the mechanisms required for the induction of second and third order suppressor cells.
