α7 nicotinic acetylcholine receptor (α7nAChR) is widely expressed in the central nervous system and immune system, and plays a neuro-immunoregulatory role. On the one hand, α7nAChR is involved in the transmission of neurotransmitters, the conduction of excitatory signals and the maintenance of synaptic plasticity, which is of great significance for maintaining the normal and stable neurocognitive function. On the other hand, as an important part of the cholinergic anti-inflammatory pathway, α7nAChR is involved in the regulation of physiological and pathological processes such as inflammatory response, oxidative stress, apoptosis and autophagy in the central system, and plays an immunomodulatory and neuroprotective role, thus being potential target for improving perioperative neurocognitive function. This article reviews the biological characteristics of α7nAChR and its effect on perioperative neurocognitive function, in order to provide ideas and methods for clinical improvement of perioperative neurocognitive function in surgical patients.
