A common feature of both diseases is aberrant immunity in respiratory epithelia that is mainly regulated by Toll-like receptors (TLRs), key regulators of innate immunity. The function of the flagellin-sensing TLR5 in airway epithelia and pathophysiology of COPD and LC has remained elusive. We performed case-control genetic association and functional studies on the importance of TLR5 in COPD and LC development, comparing Caucasian COPD/LC patients (n = 974) and healthy donors (n = 1283). Association analysis of three single nucleotide polymorphisms (SNPs) (rs725084, $rs2072493_N592S,$ and $rs5744174_F616L)$ indicated the minor allele of $rs2072493_N592S$ to be associated with increased risk for COPD (OR = 4.41, p < 0.0001) and NSCLC (OR = 5.17, p < 0.0001) development and non-small cell LC risk in the presence of COPD (OR = 1.75, p = 0.0031). The presence of minor alleles (rs5744174 and rs725084) in a co-dominant model was associated with overall survival in squamous cell LC patients. Functional analysis indicated that overexpression of the $rs2072493_N592S$ allele affected the activation of NF-κB and AP-1, which could be attributed to impaired phosphorylation of p38 and ERK. Overexpression of TLR5N592S was associated with increased chemosensitivity in the H1299 cell line. Finally, genome-wide transcriptomic analysis on WI-38 and H1299 cells overexpressing TLR5WT or TLR5N592S, respectively, indicated the existence of different transcription profiles affecting several cellular pathways potentially associated with a dysregulated immune response. Our results suggest that TLR5 could be recognized as a potential biomarker for COPD and LC development with functional relevance.}, keywords = {COPD (Other) / NSCLC (Other) / SNP (Other) / TLR5 (Other) / chemoresistance (Other) / survival (Other)}, cin = {B062 / HD01}, ddc = {570}, cid = {I:(DE-He78)B062-20160331 / I:(DE-He78)HD01-20160331}, pnm = {312 - Funktionelle und strukturelle Genomforschung (POF4-312)}, pid = {G:(DE-HGF)POF4-312}, typ = {PUB:(DE-HGF)16}, pubmed = {pmid:36140341}, doi = {10.3390/biomedicines10092240}, url = {https://inrepo02.dkfz.de/record/181827}, }
