Post-transcriptional regulons coordinate the initiation and resolution of inflammation.

Transcriptional control mechanisms chart the course of the inflammatory response by synthesizing mRNAs encoding proteins that promote or inhibit inflammation. Because these mRNAs can be long-lived, turning off their synthesis does not rapidly stop or change the direction of inflammation. Post-transcriptional mechanisms that modify mRNA stability and/or translation provide more rapid and flexible control of this process and are particularly important in coordinating the initiation and resolution of inflammation. Here, I review the surprising variety of post-transcriptional control mechanisms that regulate the initiation and resolution of inflammation and discuss how these mechanisms are integrated to coordinate this essential process.
