1 Addition of IL-1 to macrophage-depleted primary cultures of mouse Leydig cells caused a dose-dependent decrease in cAMP-dependent testosterone production and 17 alpha-hydroxylase/C17-20 lyase (P450c17) mRNA levels. Cyclic AMP interleukin 1 complex Mus musculus
2 IL-1 caused a dose-dependent decrease in 8-Br-cAMP-stimulated P450c17 levels (0.2 U/ml by 31 +/- 9%, 2 U/ml by 82 +/- 12%, and 10 or 20 U/ml by 100% compared to that in cells treated with 8-Br-cAMP alone). Cyclic AMP interleukin 1 complex Mus musculus
3 The inhibitory effect of IL-1 on 8-Br-cAMP-stimulated P450c17 expression was reversible. Cyclic AMP interleukin 1 complex Mus musculus
