Topology and dynamics of signaling networks: In search of transcriptional control of the inflammatory response

Over the past several decades, to develop a fundamental understanding of lammation's progression, research has focused on extracellular mediators, such as cytokines, as characteristic components of lammatory response. These efforts have recently been complemented by advances in proteomics that allow analysis of multiple signaling proteins in parallel, to provide more complete mechanistic models of lammation. In this review, we discuss various techniques for assessing protein activity, as well as computational techniques that are well suited for interpreting large amounts of proteomic data to generate signaling networks or for modeling the dynamics of known network interactions. We also discuss examples that explore these experimental and computational techniques in tandem to generate signaling networks under various conditions and that link those networks to transcriptional activity. Further advancements in this field will likely provide an explicit description of lammatory response, paving the way for better diagnostics and therapies in clinic.
