Topics Covered

• Nuclear receptors comprise a superfamily of ligand- and signal-dependent transcription factors that regulate diverse aspects of reproduction, development, metabolism and immunity
• Recent studies have demonstrated that a subset of nuclear receptors can co-ordinately regulate aspects of inflammation and metabolism that impact on the development of atherosclerosis and type 2 diabetes by inhibiting transcriptional responses to toll like receptors
• The nuclear receptor co-repressor NCoR plays a key role in maintaining inflammatory response genes in a repressed state under basal conditions
• PPARg inhibits inflammatory responses by preventing the removal of NCoR from target genes
