Here we show that elevated cAMP levels in T cells correlate with the expression of the potent transcriptional repressor ICER ( inducible cAMP early repressor ) previously described in the hypothalamic-pituitary-gonadal axis .
 protein: ICER; cell type: T cells; protein: inducible cAMP early repressor; protein: potent transcriptional repressor
