Receptors for IgG molecules on human lymphocytes forming spontaneous rosettes with sheep red cells

A mixed rosette techinque with sheep red blood cells (SRBC) and ox erythrocytes heavily coated with rabbit antibody (EA) was employed to simultaneously idnetify human peripheral blood T lymphocytes and IgG receptor‐bearing cells. The findings of a noticeable proportion of „mixed resettes”︁ in peripheral blood lymphocytes freshly drawn from normal individuals and of an even higher number of these mixed rosettes in cell suspension kept in culture media supplemented with fetal calf serum provide evidence for the capacity iof human T cells to express membrane receptors for antigen‐antibody complexes.
