Previously, we observed increased serum levels of damage-associated molecular patterns (DAMPs) during COPD exacerbations. Here, gene expression of DAMP receptors was measured in peripheral blood neutrophils of COPD patients during stable disease and severe acute exacerbation. The expression of toll-like receptor (TLR) 2, TLR4 and NLR family, pyrin domain-containing 3 (NLRP3) was significantly increased, while serum levels of the soluble form of the decoy receptor for advanced glycation end-product (sRAGE) were decreased during exacerbation. Together, these data indicate that increased DAMP signalling contributes to activation of neutrophils during COPD exacerbations.
