title: Effect of cyclic AMP and theophylline on phagocytotic activity of Tetrahymena pyriformis.
abstract: Dibutyril cAMP and the cPDE-inhibitor theophylline both enhance the phagocytotic activity of Tetrahymena. Theophylline and cAMP-activating histamine are synergistic. It follows that the cAMP-adenylcyclase system functions in the unicellular animal Tetrahymena.
