ALLOANTIGEN RECOGNITION IS PRECEDED BY NONSPECIFIC ADHESION OF CYTOTOXIC T-CELL AND TARGET-CELLS SCIENCE Spits, H., VANSCHOOTEN, W., Keizer, H., VANSEVENTER, G., VANDERIJN, M., TERHORST, C., deVries, J. E. 1986; 232 (4748): 403-405

Abstract

T-cell receptors bind antigens only when the antigens are exposed on the cell surface. This can be studied best in the interaction of cytolytic T lymphocytes (CTL) with target cells because the recognition and binding event can be separated from the lytic phase. Studies with CTL clones specific for HLA-A2 and HLA-B7 demonstrated that conjugates of CTL's and target cells can be formed in the absence of specific antigen recognition. Furthermore, T-cell receptor and target antigen cannot interact unless there is conjugate formation. This indicates that nonspecific conjugate formation between CTL's and target cells precedes the recognition of specific antigen by the T-cell receptor.
