title: Cytokine expression profile over time in burned mice.
abstract: The persistent inflammatory response induced by a severe burn increases patient susceptibility to infections and sepsis, potentially leading to multi-organ failure and death. In order to use murine models to develop interventions that modulate the post-burn inflammatory response, the response in mice and the similarities to the human response must first be determined. Here, we present the temporal serum cytokine expression profiles in burned mice in comparison to sham mice and human burn patients. Male C57BL/6 mice were randomized to control (n=47) or subjected to a 35% TBSA scald burn (n=89). Mice were sacrificed 3, 6, 9, 12, 24, and 48 h and 7, 10, and 14 days post-burn; cytokines were measured by multi-plex array. Following the burn injury, IL-6, IL-1beta, KC, G-CSF, TNF, IL-17, MIP-1alpha, RANTES, and GM-CSF were increased, p<0.05. IL-2, IL-3, and IL-5 were decreased, p<0.05. IL-10, IFN-gamma, and IL-12p70 were expressed in a biphasic manner, p<0.05. This temporal cytokine expression pattern elucidates the pathogenesis of the inflammatory response in burned mice. Expression of 11 cytokines were similar in mice and children, returning to lowest levels by post-burn day 14, confirming the utility of the burned mouse model for development of therapeutic interventions to attenuate the post-burn inflammatory response.
