title: Lithium: a modulator of cyclic AMP-dependent events in lymphocytes?
abstract: Theophylline, salbutamol, isoproterenol, and dibutyryl cyclic AMP inhibited E-rosette formation by human T lymphocytes and immunoglobulin M secretion from human plaque-forming B cells and augmented T-suppressor cell activity in three patients with agammaglobulinemia. Lithium chloride increased mitogen-induced lymphocyte proliferation and inhibited suppressor cell activity. In the presence of lithium, the effects of all the drugs except dibutyryl cyclic AMP could be prevented. The data suggest a role for lithium in the modulation of cyclic AMP-dependent events in lymphocytes. Its potential role as an inhibitor of suppressor cell activity warrants further attention.
