Systems biology markup language (SBML) compliant network of interactions between C. difficile and cellular immune components created in CellDesigner. Reaction modifiers connect cell nodes to reaction arrows with green as indication of activation and red of inhibition. Species consist of C. difficile (Cdiff), infection-exacerbating commensal bacteria (CommH), protective commensal bacteria (CommB), dead commensal bacteria (CommD), epithelial cells (E), inflamed epithelial cells (Ei), neutrophils (N), macrophages (M), dendritic cells (tDC and eDC), T cells (nT, Treg, Th17, Th1) existing in multiple compartments lumen (Lum), epithelium (EP), lamina propria (LP), and mesenteric lymph node (MLN).
