英文摘要Our previous study found that activation of adenosine A1 receptor (A(1)R) induced phosphorylation of delta opioid receptor (DOR) and desensitization of its downstream signaling molecules, cAMP and Akt. To further investigate the effect of A(1)R agonist on DOR signaling and the underlying mechanism, we examined the effect of A(1)R activation upon binding of its agonist N6-cyclohexyl-adenosine (CHA) on DOR-mediated Raf-1/MEK/ERK activation, and found that prolonged CHA exposure resulted in downregulation of DOR-mediated Raf-1/MEK/ERK signaling pathway. CHA-treatment time dependently attenuated Raf-1-Ser338 phosphorylation induced by [D-Pen2,5] enkephalin (DPDPE), a specific agonist of DOR, and further caused downregulation of the Raf-1/MEK/ERK signaling pathway activated by DOR agonist. Moreover, CHA exposure time-dependently induced the phosphorylation of Raf-1-Ser289/296/301, the inhibitory phosphorylation sites that were regulated by negative feedback, thereby inhibiting activation of the MEK/ERK pathway, and this effect could be blocked by MEK inhibitor U0126. Finally, we proved that the heterologous desensitization of the Raf-1/MEK/ERK cascade was essential in the regulation of anti-nociceptive effect of DOR agonists by confirming that such effect was inhibited by pretreatment of CHA. Therefore, we conclude that the activation of A(1)R inhibits DOR-mediated MAPK signaling pathway via heterologous desensitization of the Raf-1/MEK/ERK cascade, which is a result of ERK-mediated Raf-1-Ser289/296/301 phosphorylation mediated by activation of A(1)R.
