Proliferation of cells and intracellular c-AMP content: comparative investigations of autologous lymphatic cells from palatine tonsils, nasopharyngeal tonsils, and blood.

The c-AMP content and thymidine incorporation were determined in tonsillogenic, adenoid, and peripheral lymphatic cells. A significant c-AMP decrease with simultaneous increase of the thymidine incorporation compared to the blood lymphocytes was noted in the tonsillogenic and adenoid cells. The negative regulative effect of c-AMP on cell proliferation and the function of tonsils at this processes are discussed.
