title: WDPCP regulates the ciliogenesis of human sinonasal epithelial cells in chronic rhinosinusitis.
abstract: Damage to the mucociliary clearance system is a typical change in the pathogenesis in chronic rhinosinusitis. However, the mechanisms underlying cilia loss remain unclear. WDPCP is a key protein essential for ciliogenesis, and is also an effector of the planar cell polarity signaling system. In this study, we sought to determine the role of WDPCP in cilia loss in patients with chronic rhinosinusitis. We demonstrated the expression of WDPCP in human sinonasal epithelium from patients with chronic rhinosinusitis and control subjects. We also used air-liquid interface to culture primary human sinonasal epithelial cells in-vitro model and to investigate WDPCP function. We then explored links between rhinosinusitis, WDPCP and inflammation. Accompanied with cilia loss, expression of WDPCP in human sinonasal epithelium from patients with chronic rhinosinusitis was decreased significantly compared with control subjects. In vitro study, we found that WDPCP level increased at first, and then decreased. Inhibiting WDPCP expression could lead to the poor quantity and length of cilia with reduced expression of Septin7. Also, Th1 type inflammatory mediators could decrease the expression of WDPCP. In conclusion, inflammatory cytokines cause reduced WDPCP expression, which contributes to impaired ciliogenesis in human rhinosinusitis.
