Research Abstract |
Severely burn-injured hosts are known to be highly susceptible to bacterial infections/sepsis, and their outcomes become extremely poor due to infectious complications. Their host defense systems against infections, such as Th1-mediated cellular immunity, Th2-mediated humoral immunity and neutrophil-mediated immunity, are severely and multifactorially impaired. Multiple IL-18 injections can effectively restore these impaired immune responses in the immunocompromised mice receiving severe burn injury, thus improving their survival after bacterial infections. IL-18 therapy also restored burn injury-induced phenotypic alteration of Kupffer cells, namely increasing CD68+ Kupffer cells but decreasing CD11b+ Kupffer cells.
