| Research Abstract |
To establish the clinical relevance of the orphan receptors as novel therapeutic targets for treatment of asthma, we examined the expression of the orphan receptors in airway smooth muscle, the orphan receptor-mediated airway remodeling and its intracellular signaling pathways.
The orphan receptor GPR40, 41, 43, 84, 119, 120 and 132 were expressed on airway smooth muscle cells. We identified that the long-chain free fatty acids, which are natural ligands for GPR40, stimulated airway smooth muscle cell proliferation. Furthermore, we revealed that PI3 kinase and Akt are involved in GPR40-mediated airway smooth muscle cell proliferation.
