“…In this study, we introduce an in silico mechanistic modeling approach to investigate the dynamics of the post-burn immune response. Agent-based modeling (ABM) techniques, specifically the Glazier-Graner-Hogeweg (GGH) model ( 30 ), is used to simulate the behavior of inflammatory agents and the dynamics of entities involved in burn wound inflammation ( 31 , 32 ). By combining relevant experimental knowledge, data from existing experimental animal burn models, and mathematical principles ( 33 , 34 ), our approach provides a comprehensive framework for studying the intricate dynamics of the (acute) immune response in burn wounds.…”

IntroductionBurns are characterized by a massive and prolonged acute inflammation, which persists for up to months after the initial trauma. Due to the complexity of the inflammatory process, Predicting the dynamics of wound healing process can be challenging for burn injuries. The aim of this study was to develop simulation models for the post-burn immune response based on (pre)clinical data.MethodsThe simulation domain was separated into blood and tissue compartments. Each of these compartments contained solutes and cell agents. Solutes comprise pro-inflammatory cytokines, anti-inflammatory cytokines and inflammation triggering factors. The solutes diffuse around the domain based on their concentration profiles. The cells include mast cells, neutrophils, and macrophages, and were modeled as independent agents. The cells are motile and exhibit chemotaxis based on concentrations gradients of the solutes. In addition, the cells secrete various solutes that in turn alter the dynamics and responses of the burn wound system.ResultsWe developed an Glazier-Graner-Hogeweg method-based model (GGH) to capture the complexities associated with the dynamics of inflammation after burn injuries, including changes in cell counts and cytokine levels. Through simulations from day 0 – 4 post-burn, we successfully identified key factors influencing the acute inflammatory response, i.e., the initial number of endothelial cells, the chemotaxis threshold, and the level of chemoattractants.ConclusionOur findings highlight the pivotal role of the initial endothelial cell count as a key parameter for intensity of inflammation and progression of acute inflammation, 0 – 4 days post-burn.
