[Comparative study of different types of rosette-forming cells in human peripheral blood and tonsils]

E-, EA-, and EAC-reaction of rosette formation and detection of surface immunoglobulins were applied to the comparative study of the peripheral blood lymphocytes populations and tonsils in man. The relative lymphocyte content with different surface characteristics differed significantly in these populations. In detection of surface immunoglobulins on EAC-rosette forming cells it was revealed that not all the C3-lymphocytes of the tonsils bore surface Ig. A possibility of appearance of the C3-receptor on the activated T-lymphocytes is discussed.
