[Research progress of exploring the treatment of sepsis based on cholinergic anti-inflammatory pathway]

The cholinergic anti-inflammatory pathway (CAP) is an important neuroimmunomodulatory mechanism that innervates the spleen through vagus nerve efferent and splenic nerve relay, and acts on macrophages by transforming adrenergic stimulation into cholinergic signal by spleen T cells, which plays an anti-inflammatory effect, and maintains the balance of inflammatory response. Due to the critical role of the imbalance of pro-inflammatory and anti-inflammatory responses in the physiological process of sepsis, regulating the activity of the CAP has become an important focus in the treatments of sepsis. Based on the understanding of the CAP, vagus nerve stimulation, drug agonists mimicking cholinergic signals, and acupuncture are currently applied in the research and exploration of sepsis treatment. This article summarizes the recent progress and prospects of the CAP mechanism, biological effects, and application in sepsis treatment.
