We have previously shown a relation between inflammatory cytokines and expression of JE‐specific genes, such as amelotin (AMTN) 5, 6, 7, 8, odontogenic ameloblast‐associated protein (ODAM) and follicular dendritic cell‐secreted protein (FDC‐SP) 9, 10, 11, during dental development and regeneration of JE in gingival epithelial cells and a Porphyromonas gingivalis (Pg)‐ and Aggregatibacter actinomycetemcomitans‐infected mouse periodontitis model 12. The gene discussed is ODAM; the disease is periodontitis.
