T cell-depleted, Sephadex G-10-passed unstimulated splenic B cells from C57BL/6 mice stimulated splenic T cells from CKB mice to produce IL 2 and to proliferate. The stimulatory ability of the unstimulated B cells was eliminated by 4000 rad irradiation of the unstimulated stimulator B cells. LPS-activated B cells could stimulate responder T cells more efficiently than unstimulated B cells. For further analysis of allostimulation by B cells, we established a series of alloreactive T cell hybridomas. Forty-five percent of these alloreactive T cell hybridomas could be stimulated to produce IL 2 by either macrophage-dendritic cells or unstimulated B cells. Fifty-five percent of these alloreactive T cell hybridomas could be stimulated by macrophage-dendritic cells but not by unstimulated B cells. T cell hybridomas that were not reactive with unstimulated B cells were also nonreactive to LPS-activated B cells. Analysis of two representative I-Ab-reactive T cell hybridoma clones, B cell-reactive clone CB-11.4 and B cell-nonreactive clone HTB-9.3, revealed again that the stimulatory ability of unstimulated B cells was sensitive to 4000 rad irradiation in the activation of CB-11.4 clone and that CB-11.4 could be stimulated more efficiently by LPS-activated B cells than by unstimulated B cells, but HTB-9.3 could not be stimulated by LPS-activated B cells. Thus, there may be two distinct types of T cells in the alloreaction: B-cell-reactive and B cell-nonreactive.
