The Role of the Transcription Factor CREB in Immune Function JOURNAL OF IMMUNOLOGY Wen, A. Y., Sakamoto, K. M., Miller, L. S. 2010; 185 (11): 6413-6419

Abstract

CREB is a transcription factor that regulates diverse cellular responses, including proliferation, survival, and differentiation. CREB is induced by a variety of growth factors and inflammatory signals and subsequently mediates the transcription of genes containing a cAMP-responsive element. Several immune-related genes possess this cAMP-responsive element, including IL-2, IL-6, IL-10, and TNF-?. In addition, phosphorylated CREB has been proposed to directly inhibit NF-?B activation by blocking the binding of CREB binding protein to the NF-?B complex, thereby limiting proinflammatory responses. CREB also induces an antiapoptotic survival signal in monocytes and macrophages. In T and B cells, CREB activation promotes proliferation and survival and differentially regulates Th1, Th2, and Th17 responses. Finally, CREB activation is required for the generation and maintenance of regulatory T cells. This review summarizes current advances involving CREB in immune function--a role that is continually being defined.
