This cytokine appears to be a critical regulator of the inflammatory pathways leading to systemic inflammatory response syndrome and subsequent multiple organ dysfunction syndrome. This report provides an integrated scheme describing the manner by which MIF controls the neurohormonal response and the adaptive immune system namely the T-helper Th 1 and Th2 lymphocytes which results in the release of pro-inflammatory cytokines and the anti-inflammatory cytokine interleukin-10. The development of systemic inflammatory response syndrome and subsequent development of multiple organ dysfunction syndrome appear to be related to MIF levels and the balance of Th1 and Th2 function. Introduction For the survival for all living creatures an appropriate and balanced immune response to invading micro-organisms is essential. However in the case of cardiovascular surgery resembling sepsis and injury an exaggerated inflammatory response described as systemic inflammatory response syndrome SIRS may result in multiple organ dysfunction syndrome MODS . The report by de Mendonga-Filho and coworkers 1 included in this issue of Critical Care demonstrates that a SIRS cytokine namely macrophage migration .
