The monocyte depleted peripheral blood mononuclear cells were saparated into B, CD,4,+, and CD,8,+, subpopulations by a Panning technique with McAb CD,4, and CD,8,. The purity of the B, CD,4,+, and CD,8,+, subpopulations was 82.7%, 90.4%and 90.8% respectively, which was estimated by an indirect immunofluorescence technique. More than 92% of the three subpopulations were viable according to the trypan blue exclusion test. The modulation function of ConA-induced CD,4,+, and CD,8,+, cells and the effect of 10 Gy ,60,Co γ rays on them were investigated by the ,3,HTdR incorporation method. It demonstrated that the transformation of LPS-induced B lymphocytes was suppressed by the ConA-induced CD,4,+, and CD,8,+, cells. After irradiation, the suppressor activity of ConA-induced CD,4,+, and CD,8,+, cells did not decrease. It also showed that the suppressor activity ,of, ConA-induced CD,8,+, cells was enhanced by the ConA-induced CD,4,+, cells significantly, and the suppressor activity of ConA-induced CD,4,+, cells was also enhanced by the ConA-induced CD,8,+, cells. After irradiation, the enhancement effects of the ConA-induced CD,4,+, and CD,8,+, cells disappeared.
