Predicted dynamics of Th1 and Th2 cells in mouse models of acute inflammation. A differential equation model of acute inflammation was modified to include DC, Th1 cells, and Th2 cells. The model was partially calibrated against trajectories of TNF-α, IL-6, IL-10, and NO2−/NO3− obtained from C57Bl/6 mice subjected to endotoxemia (A), surgical cannulation trauma (B), or surgical cannulation+hemorrhagic shock (C). Predicted trajectories of Th1 and Th2 cells are shown for the three inflammatory scenarios.
