title: Cyclic adenosine 3',5'-monophosphate response to dopamine in mouse lymphoid cells and cell lines.
abstract: Cyclic adenosine 3',5'-monophosphate responses to dopamine and isoproterenol were studied in mouse and rat spleen, thymus, lymph nodes and Peyer's patches lymphocytes and in 7 mouse cell lines of T- and B-lymphoid derivation. The responses of normal cells to dopamine were moderate, of the same extent, but selective to spleen and thymus in mouse, and to spleen and lymph nodes in rat. The YAC-1 T lymphoma cell line was sensitive to dopamine with a higher magnitude than normal lymphoid cells. Dopamine was less potent than isoproterenol in all cells, and whereas dopamine-sensitive and isoproterenol-sensitive cells, or dopamine-insensitive and isoproterenol-insensitive cells were found, no cell type was dopamine-sensitive and isoproterenol-insensitive. Altogether, these results suggest that only a small subset of lymphocytes is susceptible to the cAMP-elevating action of dopamine.
