Cells of the innate immune system regulate immune responses through the production of antimicrobial peptides, chemokines, and cytokines, including human beta-defensins (hBDs) and CCL20. In this study, we examined the kinetics of primary human oral epithelial cell (HOEC) production of CCL20 and hBDs in response to Fusobacterium nucleatum, a commensal bacterium of the oral cavity, which we previously showed promotes HOEC induction of hBDs. HOECs secrete maximal levels of CCL20 at 6 h, following stimulation by F. nucleatum cell wall (FnCW). The kinetics of CCL20 release is distinct from that of hBD-2 and -3, which peaks after 24 h and 48 h of FnCW stimulation, respectively. FnCW-induced release of CCL20 by HOECs requires both transcriptional and translational activation. Release of CCL20 by HOECs is inhibited by brefeldin A, suggesting that it is secreted through a vesicle transport pathway. Other epithelium-derived agents that FnCW induces, such as hBD-2, hBD-3, tumor necrosis factor alpha (TNF-α) and interleukin-1β (IL-1β), are also able to release CCL20. By focusing on mitogen-activated protein kinases, we show that both extracellular signal-regulated kinase 1/2 and p38, but not JNK, are required for hBD-, TNF-α-, and IL-1β-induced secretion of CCL20 by HOECs. The ability of FnCW and its induced hBDs to produce proinflammatory cytokines and CCL20 suggests the broad role of F. nucleatum and human antimicrobial peptides in primary immune responses elicited by oral epithelium.
