1 Prostaglandin E2 and other cyclic AMP elevating agents inhibit interleukin 2 gene transcription by counteracting calcineurin-dependent pathways. Dinoprostone interleukin 2 Homo sapiens
2 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. Dinoprostone interleukin 2 Homo sapiens
3 We report here that PGE2 markedly reduces the IL-2 promoter activity that is induced by a constitutively active form of calcineurin. Dinoprostone interleukin 2 Homo sapiens
4 In contrast to the complete inhibition of promoter activity produced by the immunosuppressants cyclosporin A and FK-506, this partial block suggests that PGE2 modulates downstream events needed for lymphokine gene activation. Dinoprostone interleukin 2 Homo sapiens
