Abstract

Methylxanthines and catecholamines both inhibit antigenically induced histamine release from human leukocytes. They act synergistically to inhibit the reaction, but must be present when antigen is added; preincubation is not effective. Since both increase cellular levels of cyclic 3 ', 5'-adenosine monophosphate it is postulated that this compound plays a role in the regulation of allergic histamine release.
