Functional characterization of OR51B5 and OR1G1 in human lung epithelial cells as potential drug targets for non-type 2 lung diseases

Background Hypersensitivity to odorants like perfumes can induce or promote asthma with non-type 2 inflammation for which therapeutic options are limited. Cell death of primary bronchial epithelial cells (PBECs) and the release of the pro-inflammatory cytokines interleukin-6 (IL-6) and IL-8 are key...

description Background Hypersensitivity to odorants like perfumes can induce or promote asthma with non-type 2 inflammation for which therapeutic options are limited. Cell death of primary bronchial epithelial cells (PBECs) and the release of the pro-inflammatory cytokines interleukin-6 (IL-6) and IL-8 are key in the pathogenesis. Extra-nasal olfactory receptors (ORs) can influence cellular processes involved in asthma. This study investigated the utility of ORs in epithelial cells as potential drug targets in this context. Methods We used the A549 cell line and primary bronchial epithelial cells using air–liquid interface culture system (ALI-PBECs). OR expression was investigated by RT-PCR, Western blot, and Immunofluorescence. Effects of OR activation by specific ligands on intracellular calcium concentration, cAMP, Phospholipase C (PLC), cell viability, and IL-6 and IL-8 secretion were analyzed by calcium imaging, enzyme immunoassays, Annexin V/ propidium iodide -based fluorescence-activated cell staining or by ELISA, respectively. Results By screening A549 cells, the OR51B5 agonists Farnesol and Isononyl Alcohol and the OR1G1 agonist Nonanal increased intracellular Ca2 + . OR51B5 and OR1G1 mRNAs and proteins were detected. Both receptors showed a preferential intracellular localization. OR51B5- but not OR1G1-induced Ca2 + dependent on both cAMP and PLC signaling. Farnesol, Isononyl Alcohol, and Nonanal, all reduced cell viability and induced IL-8 and IL-6 release. The data were verified in ALI-PBECs. Conclusion ORs in the lung epithelium might be involved in airway-sensitivity to odorants. Their antagonism could represent a promising strategy in treatment of odorant-induced asthma with non-type 2 inflammation. Graphical Abstract
