    Notes: Interleukin (IL-)10 has been demonstrated to inhibit endotoxin-induced production of a number of pro-inflammatory cytokines. The present study sought to compare the appearances in the circulation of IL-10, IL-6 and IL-8, and to assess the roles ofendogenously produced platelet-activating factor (PAF) and IL-6 in IL-10 release during endotoxaemia in chimpanzees. Intravenous injection of endotoxin (lot EC-5, 4 ng/kg, n = 8) induced a transient rise in serum IL-10concentrations, peaking after 2 h (213 ± 70 pg/ml; P 〈 0.05). No correlations existed between peak IL-10 levels, and peak IL-6 and IL-8 levels. Neither infusion of the specific PAF antagonist TCV-309(n = 4), nor infusion of a neutralizing anti-IL-6 monoclonal antibody (n = 4) influenced endotoxin-induced IL-10 release. IL-10 release elicited by injection of endotoxin is not mediated by PAF or IL6.

    Description / Table of Contents: Summary In pneumonia the initiation, maintenance, and resolution of inflammation is dependent upon the complex network of pro-inflammatory and anti-inflammatory cytokines. Much of our knowledge of the role of cytokines in the pathogenesis of pneumonia is derived from animal studies on experimental pneumonia. In contrast to systemic infection, where excessive production of pro-inflammatory cytokines is detrimental, causing organ failure and death, local production of pro-inflammatory cytokines is necessary for host defense against the invasive pathogen. Conversely, the anti-inflammatory cytokine IL-10 impairs host defense in local infections like pneumonia, while it protects against excessive immune activation, like sepsis. Studies on the role of cytokines in pneumonia in humans and animals are discussed in detail.
    Notes: Zusammenfassung Bei einer Pneumonie hängen das Aufkommen, das Fortbestehen und der Ausgang einer Entzündung von einem komplexen Netzwerk pro- und anti-entzündliche Zytokine ab. Vieles, was wir über die Rolle der Zytokine in der Pathogenese der Pneumonie wissen, wurde in tierexperimentellen Pneumoniestudien erhoben. Gegenüber systemischen Infektionen, in welchen eine Überproduktion der pro-entzündlichen Zytokine schädlich ist und zum Organversagen und zum Tod führt, ist eine lokale Produktion von pro-entzündlichen Zytokinen notwendig zur Immuna-Abwehr gegen die invasiven Erreger. Umgekehrt hindert das anti-entzündliche Zytokin IL-10 die Host-Abwehr bei lokalen Infekten wie der Pneumonie, während es gegen einer übermäßige Immunaktivierung, wie Sepsis, schützt. Studien über die Rolle der Zytokine bei einer Pneumonie bei Mensch und Tier werden ausführlich diskutiert.
