Definitions
- P2X receptors are non-selective ATP-gated ion channel receptors, purinergic receptors, that bind to extracellular ATP, mainly from damaged or inflamed tissues.
- the receptor is widely expressed in the nervous, immune, cardiovascular, skeletal, gastrointestinal, respiratory, endocrine and other systems, and is involved in the regulation of cardiac rhythm and contractility, the regulation of vascular tone, the regulation of nociception, especially chronic pain, and the contraction of the vas deferens during ejaculation. , bladder contraction during voiding, aggregation of platelets, activation of macrophages, apoptosis, and neuron-glial interactions and other physiological processes.
- P2X3 and P2X2/3 expressed in primary sensory neurons plays an important role in acute injury, hyperalgesia, and hypersensitivity in rodents.
- Many studies have shown that the up-regulation of P2X3 receptor expression can lead to the formation of hyperalgesia, which is involved in pain signaling.
- P2X3 knockout mice exhibited reduced pain responses, and P2X3 receptor antagonists were shown to reduce nociception in models of pain and inflammatory pain.
- P2X3 is distributed in primary afferent nerves around the airways and is capable of regulating cough.
- P2X3 receptors play an important role in cough reflex hypersensitivity. By antagonizing and binding to P2X3 receptors, the hypersensitivity of the cough reflex can be inhibited, thereby suppressing excessive coughing in patients with chronic cough.
- P2X3 antagonists can treat chronic obstructive pulmonary disease, pulmonary fibrosis, pulmonary hypertension or asthma, so P2X3 antagonists are also expected to become new drugs for the treatment of these diseases.
- P2X3 is involved in the afferent pathway that controls the bladder volume reflex, and P2X3 knockout mice have significantly reduced urination frequency and significantly increased bladder capacity.
- P2X3 antagonists may be potential drugs for the treatment of overactive bladder and other related diseases.
- P2X3 antagonists show great promise.
- the commonly used cough drugs gabapentin, morphine and amitriptyline, or speech pathology can improve cough in many patients, but they are not suitable for all patients, and gabapentin
- Such central drugs may have adverse side effects and are not suitable for long-term medication.
