Abstract
A high percentage of human cord-blood lymphocytes bears receptors for peanut agglutinin. Determination of the presence of other lymphocyte markers (erythrocyte rosettes, membrane Ig, .alpha.-naphthyl-acetate esterase, Ia antigens) in the peanut-positive cells indicated that they include both T and B cells. The peanut receptor, also expressed by blast cells of most acute, but not chronic leukemias, seems to be a marker of immaturity for both T and B lymphocyte subsets in man as it is in the mouse.
