We found that receptor activator of NF-κB (RANK) ligand (RANK-L (TNFSF11)) was significantly elevated in nasal polyps (NPs), and that the receptor of RANK-L, RANK, was expressed on ILC2s in human peripheral blood and NPs.
Compared with control subjects, although mRNA and protein expression of IL-37 were upregulated in diseased tissues, especially in nasal epithelial cells, in patients with CRS without nasal polyps or in patients with chronic rhinosinusitis with nasal polyps (CRSwNP), IL-37 levels in nasal secretions were reduced in patients with eosinophilic CRSwNP.
ACT-774312 is an antagonist of the chemoattractant receptor-homologous molecule expressed on T helper (Th) 2 cells (CRTH2), in development for the treatment of nasal polyposis or other allergic and type-2 inflammatory diseases.
Cytokine profile analysis showed that levels of Th17-associated mediators (myeloperoxidase, interleukin (IL)-8, IL-17A and IL-23), B-cell activating factor (BAFF) and Th1 cytokine (interferon-γ) were up-regulated in rNP compared to controls and pNP.

Our study found that H3K4me3 histone demethylase KDM2B (also known as JHDM1B) and transcriptional regulator Brg1 (also called SNF2-β or Smarca4) were significantly decreased in nasal mucosa of CRSwNP patients, and they were positively correlated.
Six months after surgery their levels were reversed to control values.CRSwNP patients with <i>S. epidermidis</i> isolated from sinus swabs showed upregulation of <i>TFF3</i> in MNT and NP as compared with patients with sterile swabs.
In addition, further investigation regarding the reason underlying miR-21 overexpression in CRSwNP could provide a molecular target for novel treatment strategies for nasal polyposis.

In our study, we observed a significantly higher level of CD80, CD274, CD273 and TLR1 in nasal polyps compared to blood samples from patients with CRSwNP.
