Subcellular signaling and response network. A) Conceptual model of the intracellular pathways governing viral-host-cell interactions, featuring viral internalization, virus sensing by the cell, viral replication, IFN production, IFN sensing, activation of ISGs, suppression of viral functions by ISG proteins, and suppression of cell immunity by the viral protein NS1. In our computational model, each cell agent contains a BSN, which includes key nodes and interactions that represent the main components of the conceptual model, implemented using the MaBoSS framework. See Supplemental Figure 1 for a code-level diagram with all nodes and logic operators. B) The agent-based tissue includes healthy, infected and dead epithelial cell objects on a 2D lattice, implemented in the CompuCell3D framework. Simulated cells interact with the extracellular concentration fields of virus and IFN. Cells’ behaviors depend on their state (healthy, infected, dead) and internal network state.
