Core Tip

Core tip: P2Y1R is believed to be part of a high-sensitivity response to mechanical stimulation but whether it is involved in visceral hypersensitivity of irritable bowel syndrome is discussing. We detected its expression in the colon of a rat model of irritable bowel syndrome, and explored its regulatory role in visceral hypersensitivity with a specific agonist and an antagonist. The abdominal withdrawal reflex and electromyography tests showed effective changes after intervention. It was interesting to note that in case of combined treatment of the two drugs, the antagonist showed higher effects, which indicated that other P2 receptors might be involved in the hypersensitivity of irritable bowel syndrome.
