We have previously shown that prostaglandin E2 and other cAMP elevating agents inhibit the nuclear transcription of the human IL-2 gene by interfering with a Ca(2+)-sensitive T cell signal transduction pathway. Calcineurin, a Ca2+/calmodulin-dependent 2B protein phosphatase, is an essential component of the T cell receptor signal transduction pathway(More)
Engagement of the T cell receptor for antigen activates phospholipase C resulting in an increase in intracellular free calcium concentration ([Ca2+]i) and activation of protein kinase C (PKC). Increased [Ca2+]i activates Ca2+/calmodulin-dependent kinases including the multifunctional Ca2+/calmodulin-dependent protein kinase II (CaM-K II), as well as(More)
