title: [The role of interleukin 1 in infection and sepsis].
abstract: Interleukin(IL-)-1 is the prototype of a proinflammatory cytokine, produced in response to infection and other forms of trauma. At low concentrations IL-1 brings about increases in a number of defense mechanisms, particularly immunologic and inflammatory responses. However, over- or continued production of IL-1, as seen for example during septic infection, significantly contributes to pathological reactions such as hemodynamic shock. Thus, it is not surprising that IL-1 activities are tightly regulated, most notably at the levels of transcription and secretion. Additional regulation is provided by the action of a protein, that blocks the binding of IL-1 to its receptors. This protein, termed IL-1-receptor antagonist (IL-1ra) has been cloned recently, and may provide the possibility of specific therapeutic measures.
