Innate Immune Response Agent-based Model (IIRABM)

What is being modeled?
Systemic Inflammation represented at the endothelial-blood interface
Description & purpose of resource

The Innate Immune Response Agent-Based Model (IIRABM) is a two-dimensional abstract representation of the human endothelial-blood interface.  This abstraction is designed to model the endothelial-blood interface for a traumatic (in the medical sense) injury, and does so by representing this interface as the unwrapped internal vascular surface of a 2D projection of the terminus for a branch of the arterial vascular network. The IIRABM operates by simulating multiple cell types and their interactions, including endothelial cells, macrophages, neutrophils, TH0, TH1, and TH2 cells as well as their associated precursor cells.  The simulated system dies when total damage (defined as aggregate endothelial cell damage) exceeds a pre-defined threshold.
