Research Abstract |
Ovarian cancer G protein-coupled receptor 1 (OGR1) stimulation by extracellular protons causes the activation of G proteins and subsequent cellular functions. We showed that OGR1-deficient mice are resistant to the cardinal features of asthma, including airway eosinophilia, airway hyperresponsiveness, and goblet cell metaplasia in a murine allergic asthma model. On the other hand, acidic pH alone induced a substantial production of connective tissue growth factor (CTGF) and enhanced transforming growth factor-beta-induced CTGF mRNA and protein expression through OGR1 in human airway smooth muscle cells. Our results suggest that OGR1 plays an important role in the pathogenesis of allergic airway inflammtion and airway remodelling and OGR1 may be a therapeutic target of asthma.
