Biological model of crosstalk between inflammatory and regulatory pathways in the gut. Solid lines represent either a reaction that induces cell differentiation from one type to another or the promotion by a cell type of a particular reaction. Dotted lines represent an inhibitory effect of a cell type on an interaction. The inflammatory pathway (right) is triggered by pathogenic (foreign) bacteria, Bf, and the regulatory pathway (left) is triggered by residential (commensal) bacteria, Bc. Each is described in the text along with other abbreviations.
