Abstract

Purpose of Review

To review innate lymphoid cells (ILCs) and their role in chronic rhinosinusitis (CRS).

Recent Findings

The immune system consists of the innate and adaptive response. Until the recognition of ILCs, chronic inflammatory diseases were characterized by cytokines linked only to T helper cells. However, these immune responses are now described more broadly to include contributions from both the innate and adaptive immunity. In CRS, focus had been on ILC2s in CRS with nasal polyps. These studies also highlight the importance of epithelial cell–derived cytokines in coordinating these responses. In addition to indirect crosstalk via cytokines, ILCs and T helper cells can utilize the OX40/OX40 ligand and major histocompatibility complex class II pathways to directly interact and coordinate responses.

Summary

In addition to T helper cells, ILCs contribute to the inflammatory response associated with CRS. The understanding of these cells along with pathways that activate and perpetuate these cells leads to new potential therapeutic targets for CRS treatment.

Nat Immunol. 2016;17(11):1291–9 This prospective observational study follows a small cohort of SCID patients before and after hematopoietic stem cell transplantation, which reconstituted the T cells without much effect on the ILC population. With follow-up from 7 to 39 years, there were no increase in susceptibility to diseases as compared to control cohort with intact T cell and ILC populations. This suggests that for immune homeostasis, ILCs may be redundant to T cells. CrossRefGoogle Scholar

Clin Immunol. 2016;170:1–8 Using flow cytometry analysis, the authors analyzed the prevalence of ILC2s within inflamed sinus mucosa and peripheral from healthy controls, eosinophilic, and non-eosinophilic CRSwNP and CRSsNP patients. They confirmed an elevated prevalence of ILC2s in CRSwNP but showed a correlation of elevated ILC2s and eosinophilic CRSwNP.

In a mouse model of parasitic infection using Nippostrongylus brasiliensis, abolishing OX40L ILC2s resulted in an inability to mount an effective Th2 and Treg cell response.
