Neuropilin-2 regulates airway inflammation in a neutrophilic asthma model.

ABSTRACT:

Background

Asthma is a heterogenous disease that can be classified into eosinophilic (type 2-high) and noneosinophilic (type 2-low) endotypes. The type 2-low endotype of asthma can be characterized by the presence of neutrophilic airway inflammation that is poorly responsive to corticosteroids. Dysregulated innate immune responses to microbial products including Toll-like receptor (TLR) ligands have been associated with the pathogenesis of neutrophilic asthma. The key molecules that regulate inflammatory responses in individuals with neutrophilic asthma remain unclear. We previously reported that the immunoregulatory receptor neuropilin-2 (NRP2) is expressed by murine and human alveolar macrophage (AM) and suppresses lipopolysaccharide (LPS)-induced neutrophilic airway inflammation
