<unk>  is part of a complex system of communication that governs basic<unk> ular activities and coordinates<unk>  actions.  The ability of<unk> s to perceive and correctly respond to their microenvironment is the basis of development, tissue repair, and immunity as well as normal tissue homeostasis.  Errors in<unk> ular information processing are responsible for diseases such as cancer, autoimmunity, and diabetes.  By understanding<unk> , diseases may be treated effectively and, theoretically, artificial tissues may be yielded.
Traditional work in biology has focused on studying individual parts of<unk>  pathways.  Systems biology research helps us to understand the underlying structure of<unk>  networks and how changes in these networks may affect the transmission and flow of information.
