Abstract

The role of monocytes in human T-cell activation by monoclonal antibodies (mAb) recognizing CD3 molecule or by 2 mAb pairs directed against different epitopes of CD2 "GT2+T11(1)" or "D66+T11(1)" has been studied. It appears that HLA-cl I molecules from monocytes are involved in the early activation phase of T-cells stimulated by CD3 or CD2 when direct contacts between T-cells and monocytes are required. Thus, pretreatment of monocytes with HLA-cl I mAb inhibited IL 2 receptor appearance and IL 2 synthesis on T-cells stimulated by CD3 mAb or CD2 "GT2+T11(1)" mAb pair.
