Correlation between active E-rosettes and antigens defined on peripheral lymphocytes by OKT 4 and OKT 8 monoclonal...

A relationship has been sought between the classical marker, active E-rosette and the surface antigens of T-lymphocytes, defined by OKT 4 and 8 monoclonal antigens, in the peripheral blood of normal human people. It was found that no significant correlation existed in the case of OKT 4 antigen; conversely the OKT 8-positive cells were significantly enriched after E-rosette-forming cell isolation (about 2.5 times in comparison with the negatively selected cells). In this latter case, some partial correlation could exist between SRBC-high affinity of T-lymphocytes and the subsets defined by OKT 8 antigen.
