  Interferon-gamma ( IFN-gamma ), also known as type II interferon, is an important immunoregulatory gene that has multiple effects on the development, maturation, and function of the immune system. IFN-gamma mRNA and protein are expressed predominantly by T cells and large granular lymphocytes. The IFN-gamma mRNA is induced/inhibited in these cell types by a wide variety of extracellular signals, thus implicating a number of diverse, yet convergent signal transduction pathways in its transcriptional control. In this review, I describe how DNA methylation and specific DNA binding proteins may regulate transcription of the IFN-gamma gene in response to extracellular signals.
