Abstract

Adenosine aggravates pain via the interactions of adenosine A2A receptor (A2AR) and adenosine A1 receptor (A1R). And heteromerization of A2AR and A1R can put adenosine into operation. Simultaneously, a growing body of information indicates Ca2+ participate in pain management. Our team proved the interaction between A1R and A2AR by Iem-spFRET method. In the present study, we estimated the influence of the dimerization on the concentration of intracellular Ca2+. These dates demonstrate that the interaction of pain-related receptors (A2AR and A1R) has a significant effect on intracellular Ca2+ signaling.
