[Immunological analysis of human lymphocytes bearing different surface receptors]

Cell surface receptors on human lymphocytes being studied, essential differences were revealed in a relative content of E-, EA- and EAC-rosette-forming cells in peripheral blood and tonsils. In tonsils, part of lymphocytes carrying receptors for sheep erythrocytes have been shown to possess C'3-receptors for sheep erythrocytes. Apparently, C'-receptor,--being B-lymphocyte surface marker,--may also appear at definite stages of T-cell differentiation.
