Despite persistent research on its etiology and pathophysiology, many aspects remain unclear. Predominant neurobiological research and traditional pharmacotherapies have pointed out the monoamine hypothesis as a pivotal factor in the pathophysiology of depression. However, emerging perspectives on the monoamine hypothesis highlight the significance of the cholinergic system, a major regulator of diverse CNS functions encompassing attention, arousal, cognition, and memory. Cognitive impairments were frequently observed in depression along with other symptoms i.e. low mood and anhedonia. A comprehensive literature search was conducted across multiple databases (PubMed, Scopus, and Web of Science) from their inception until May 2023. We screened 1,200 articles, of which 400 full-text articles were assessed for eligibility, and 231 studies met the inclusion criteria. The review included both pre-clinical and clinical studies focusing on the role of acetylcholine (ACh) and its receptors in depression. Data extraction and quality assessment were performed independently by two reviewers. In literature, both pre-clinical and clinical studies suggest that elevated central ACh levels may contribute to depression, prompting investigations into intervention strategies targeting mAChRs/nAChRs and AChE. These receptors have become a critical target in drug-design strategies aimed at addressing depression-like symptoms. In addition, research has demonstrated a significant antidepressant-like effect of AChEIs in a dose-dependent manner in animal models. Hence, this evidence over the past decades underscores the pivotal role of the cholinergic system in mood regulation, offering promise for novel depression treatments. In this review, we tried to summarize the historical evolution of the cholinergic system from early discoveries to its role in the pathophysiology of depression. It presents evidence for the involvement of mAChRs and nAChRs, as well as AChE, in depression. By outlining the cholinergic theory of depression, this review suggests a novel therapeutic approach, emphasizing the role of ACh in the complex depression pathophysiology, and presenting avenues for further research and the development of targeted interventions.</p>","PeriodicalId":29871,"journal":{"name":"Current Reviews in Clinical and Experimental Pharmacology","volume":"20 3","pages":"180-204"},"PeriodicalIF":1.3,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144200236","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Chemotherapy is the primarily used regimen for cancer treatment; however, it also brings severe side effects. Chemotherapy-induced Peripheral Neuropathy (CIPN) and Chemotherapy-induced Cognitive Impairment (CICI) are two main complications occurring in chemotherapy. They are both associated with nervous system injury and are therefore collectively referred to as Chemotherapy-induced Neuropathy (CIN). CIPN induces neuralgia and numbness in limbs, while CICI causes amnesia and cognitive dysfunction. Currently, there are no effective therapeutics to prevent or cure CIN, so research into new drugs to alleviate CIN becomes urgent. Oxidative stress and neuroinflammation are the common pathogenic mechanisms of CIPN and CICI. Excessive Reactive Oxygen Species (ROS) and pro-inflammatory cytokines cause peripheral nervous system damage and hence CIPN. Peripheral ROS and cytokines also change the permeability of the blood-brain barrier, thereby increasing oxidative stress and neuroinflammation in the central nervous system, ultimately leading to CICI. Several antidepressants have been used to treat CIN and exhibited good clinical effects. Their potential pharmacological mechanism has been reported to ameliorate oxidative stress and neuroinflammation, guiding a new feasible way for effective therapeutic development against CIN.

Motor, psychological, and cognitive symptoms characterize HD, a neurodegenerative disease. One prominent movement disorder associated with HD is chorea, which results in uncontrollably jerky movements of the muscles. HD has no known cure; instead, symptom management with a variety of medication options is the main goal. Effective management is essential because chorea has a significant impact on patients' quality of life. Dutetrabenazine is the first deuterated medication to receive approval from the US Food and Drug Administration (FDA) for the therapeutic treatment of chorea in Huntington's disease (HD). Treating chorea associated with HD may benefit from the use of deutetrabenazine. The novel compound deutetrabenazine contains deuterium. It inhibits CYP2D6 metabolism, prolongs the half-lives of active metabolites, and may cause persistent systemic exposure while maintaining significant pharmacological action. Deutetrabenazine decreases the release of monoamines, including dopamine, in the synaptic cleft by inhibiting the VMAT2 vesicular monoamine transporter. For chorea, this mechanism has a therapeutic effect. For the treatment of choreiform movement and tardive dyskinesia in HD, the FDA approved deutetrabenazine in 2017. Here we highlight, Deutetrabenazine as a promising new treatment for Huntington's disease chorea, for patients with chorea, deutetrabenazine offers hope for an enhanced quality of life.
