[Demonstration of T-lymphocyte differentiation in the tonsil by determination of surface markers with monoclonal antibodies and rosette technics].

By means of the monoclonal antibody BL-T2 and the E-rosette technique as well as by double-labelling of the E- and EAC-rosette forming cells with BL-T2, BL-Ig-L/1 and BL-DR it can be shown, that different marker patterns occur in the tonsillar lymphocyte subpopulations. These patterns are indications for T-cell differentiation processes inside the tonsil.
