The physical association of CD5 and the T cell antigen receptor (TcR)/CD3 complex on the surface of intact human lymphocytes was investigated using co-capping experiments and fluorescence resonance energy transfer (FRET) analyses. Antibody-induced capping of CD5 or CD3 and double indirect immunofluorescence labeling revealed a specific co-localization of a significant fraction of CD3 and CD5 molecules on the T cell surface. By means of FRET measurements we studied further the physical proximity of CD5 and the TcR/CD3 complex at the surface of normal lymphocytes. Significant fluorescence energy transfer was measured between CD5 and CD3 molecules indicating that the associated molecules were within 10 nm of one another. No energy transfer was observed between the integrin alpha 4 beta 7 and CD3 or CD5. The close physical proximity measured between CD5 and CD3 correlates with our co-capping data and taken together the results show that the association of CD5 and the TcR/CD3 complex first detected by immunoprecipitation occurs on the surface of human T cells under physiologically relevant conditions.
