Whole-genome methylation profiling of monocytes and alveolar-like monocyte-derived macrophages from healthy controls and NSAID-exacerbated respiratory disease (N-ERD) patients

ABSTRACT: NSAID-exacerbated respiratory disease (N-ERD) represents a particularly severe endotype of chronic rhinosinusitis with nasal polyps (CRSwNP), which affects around 10-16% of CRSwNP patients. N-ERD is characterized by severe and refractory nasal polyposis, bronchial asthma and intolerance to non-steroidal anti-inflammatory drugs (NSAIDs), including aspirin. Today, the pathogenesis of AERD remains incompletely understood and curative treatments are lacking. Macrophages are important source and target cells of arachidonic acid metabolites during type 2 inflammation, that have been neglected in N-ERD pathogenesis despite their presence in the nasal mucosa of N-ERD patients. Using a genome-wide methylomics approach, we identified persistent differences in monocytes and alveolar-like monocyte-der
