title: Effect of tuftsin on the phagocytotic activity of the unicellular Tetrahymena. Does primary interaction develop imprinting?
abstract: The natural mammalian phagocytosis stimulator tetrapeptide tuftsin stimulated also the phagocytosis of the unicellular Tetrahymena. The selectivity of the Tetrahymena was not complete, as threonin-free tuftsin provoked a greater response. Treatment with tuftsin did not develop functional imprinting, however the binding capacity of cell membrane significantly increased after the first treatment.
