Abstract: Pain-related acid-sensing ion channels 3 (ASIC3), the most sensitive acceptor to such a pH change, has been shown to be predominantly expressed in the peripheral nervous system. Over recent years, there has been increased evidence that ASIC3 may lead to the pathogenesis of chronic inflammatory pain diseases because that it is predominantly expressed in dorsal root ganglia (DRG) neurons making it a good candidate for a pain sensor. It has been shown that increased expression of ASIC3 mRNA and protein was found in DRG of rodents with inflamed joints and ASIC3 gene knock-out mice (ASIC3-/-) exhibited no enhanced hyperalgesia in inflamed joint. These findings suggest that under the physiological or pathological circumstance, ASIC3 have an important biological effect on the sensor information, especially pain transmission of the spinal cord level, which might be a promising therapeutic target for arthritis pain. In this study, we will briefly discuss the biological features of ASIC3 and summarize recent advances on the role of ASIC3 in the arthritis and during the course of its treatment.
