Enhanced effects of prostaglandin E1 and dibutyryl cyclic AMP upon human lymphocytes in the presence of cortisol.

The combined effects of cortisol and agents acting through a cyclic AMP-mediated mechanism have been studied in cultures of highly purified human peripheral lymphocytes. Incubation with prostaglandin E(1) (PGE(1)), dibutyryl cyclic AMP, or cortisol results in a concentration-dependent inhibition of [(3)H]-thymidine incorporation by both unstimulated and phytohemagglutinin (PHA)-stimulated lymph...

The effect of cyclic AMP and dibutyryl cyclic AMP on the permeability characteristics of the renal tubule.

The effect of adenosine-3',5'-cyclic monophosphate (cyclic AMP) and N(6),O(2)-dibutyryl adenosine-3',5'-cyclic monophosphate (dibutyryl cyclic AMP) on renal tubular permeability was studied by microinjection techniques in anesthetized diuretic rats. Radioactive inulin and mannitol were microinjected simultaneously into superficial proximal and distal convolutions and recovery of the isotopes wa...

Induction of cyclic AMP phosphodiesterase in Blastocladiella emersonii and its relation to cyclic AMP metabolism.

Extracts of vegetative cells of Blastocladiella emersonii contain 5% or less of the cyclic AMP phosphodiesterase activity in zoospore extracts. This difference in activity could be accounted for entirely by an increase in the differential rate of phosphodiesterase synthesis during sporulation, beginning after a lag period of about 60 min and extending for at least an additional 90 min into the ...
