Histamine H2 receptors on foetal-bovine articular chondrocytes

Abstract
The dose-response curve of histamine-induced cAMP elevation in monolayer cultures of primary fetal-bovine articular chondrocytes was displaced to the right by cimetidine. H2, but not H1, antagonists prevented the histamine-induced cAMP elevation, suggesting histamine activates chondrocyte adenylate cyclase through an H2 receptor.
