The blood–brain barrier and the blood-cerebrospinal fluid barriers are melatonin-binding sites. Among the several melatonin actions, the most characteristic one is the regulation of sleep-wake cycles, melatonin has anti-inflammatory and antioxidant properties. Since brain barriers disruption can arise from inflammation and oxidative stress, knowing the influence of melatonin on the integrity of brain barriers is extremely important.

Here we review how 5α-reductase inhibitors (5ARIs), drugs used to treat benign prostatic hyperplasia and alopecia, exhibit beneficial effects in PD animal models. 5ARIs show neuroprotective properties in brain and gut dopaminergic systems, and reduce dyskinesias in rodent model of PD. Additionally, the 5ARI finasteride dampened dopaminergic-induced drug gambling in PD patients. Neuroprotection and antidyskinetic activities of 5ARIs in animal models of PD suggest their potential repurposing in men with PD to address gut dysfunction, protect brain DA and inhibit dyskinesias.</div></div>","PeriodicalId":12469,"journal":{"name":"Frontiers in Neuroendocrinology","volume":"75 ","pages":"Article 101156"},"PeriodicalIF":6.5,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142368190","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The receptors that mediate rapid corticosteroid actions are located at or close to the plasma membrane, though many of the receptor characteristics remain unresolved. Rapid-onset corticosteroid effects play a role in fast neuroendocrine feedback as well as in higher brain functions, including increased aggression and anxiety, and impaired memory retrieval. The rapid non-genomic corticosteroid actions precede and complement slow-onset, long-lasting transcriptional actions of the steroids. Both rapid and slow corticosteroid actions appear to be indispensable to adapt to a continuously changing environment, and their imbalance can increase an individual’s susceptibility to psychopathology.</p></div>","PeriodicalId":12469,"journal":{"name":"Frontiers in Neuroendocrinology","volume":"74 ","pages":"Article 101146"},"PeriodicalIF":6.5,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0091302224000268/pdfft?md5=ed5c2dd9ec5d11f96ed806ffed5069e1&pid=1-s2.0-S0091302224000268-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141616209","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Higher levels of testosterone were associated with improved recognition and heightened sensitivity to threatening faces. In contrast, higher cortisol levels positively impacted emotion regulation ability. Indirect evidence from neuroimaging research suggested a link between higher testosterone levels and difficulties in cognitive emotion regulation. However, this notion must be investigated in future studies using different emotion regulation strategies and considering social status.
