Cell adhesion (immune system) molecules pathway containing P. gingivalis differentially regulated genes in calvarial tissue at P ≤ 0.05, adapted from Pathway Express and using the Kyoto Encyclopedia of Genes and Genomes nomenclature. Red indicates up-regulation, blue indicates repressed, and green indicates no change in gene expression. An arrow indicates a molecular interaction resulting in activation, and a line without an arrowhead indicates a molecular interaction resulting in inhibition.
