Recurrent respiratory papillomatosis (RRP) is a rare, chronic disease caused by human papillomaviruses (HPVs) types 6 and 11 that is characterized by the polarization of adaptive immune responses that support persistent HPV infection. Respiratory papillomas express elevated mRNA levels of IL-36γ, a pro-inflammatory cytokine in comparison to autologous clinically normal laryngeal tissues; however there is no evidence of inflammation in these lesions. Consistent with this, respiratory papillomas do not contain TH1-like CD4(+) T-cells or cytotoxic CD8(+) T-cells, but instead contain a predominance of TH2-like and T regulatory cells (Tregs). In addition, papillomas are also infiltrated with immature Langerhans cells (iLC). In this study we show that papilloma cells express IL-36γ protein, and that human keratinocytes transduced with HPV11 have reduced IL-36γ secretion. We now provide the first evidence that peripheral blood-derived iLCs respond to IL-36γ by expressing inflammatory cytokines and chemokines. When stimulated with IL-36γ, iLCs from patients with RRP had lower expression levels of the TH2-like chemokine CCL-20 as compared to controls. Patients' iLCs also had decreased steady state levels of CCL-1, which is a pro-inflammatory chemokine. Moreover, CCL-1 levels in iLCs inversely correlated with the severity of RRP. The combined decrease of TH1- and a TH2-like chemokines by iLCs from patients could have consequences in the priming of IFNγ expression by CD8(+) T-cells. Taken together, our results suggest that in RRP, there is a defect in the pro-inflammatory innate immune responses made by iLCs in response to IL-36γ. The consequence of this defect may lead to persistent HPV infection by failing to support an effective HPV-specific, TH1-/Tc1-like adaptive response, thus resulting in the predominant TH2-/Treg micromilieu present in papillomas.
