Integr. Neurosci."],"abstract":"<jats:p>Multiple sclerosis is a progressive autoimmune disorder of the myelin sheath and is the most common inflammatory disease of young adults. Up to 65% of multiple sclerosis patients have cognitive impairments such as memory loss and difficulty in understanding and maintaining attention and concentration. Many pharmacological interventions have been used to reverse motor impairments in multiple sclerosis patients; however, none of these drugs improve cognitive function. Melatonin can diffuse through the blood-brain barrier and has well-known antioxidant and anti-inflammatory properties with almost no side effects; it is, therefore, a promising neuroprotective supplement for many neurological diseases, such as multiple sclerosis, Alzheimer\u2019s disease, Parkinson\u2019s disease, ischemic stroke, and fibromyalgia. However, only some researches have assessed the effect of melatonin on cognitive dysfunction in multiple sclerosis. Here, we evaluated the effects of melatonin supplementation on memory defects induced by cuprizone in a mouse model of multiple sclerosis. Cuprizone (400 mg\/kg) and melatonin (80 mg\/kg) were administered to SWR\/J mice daily for 5 weeks. Open field, tail-flick, and novel object recognition behavioral tests were performed. Also, expression of cAMP-response element-binding protein, synaptophysin, and postsynaptic density protein 95 were measured in the prefrontal cortex. Melatonin significantly improved the memory defects induced by cuprizone toxicity by up-regulating cAMP-response element-binding protein and by increasing expression of the synapse-associated synaptophysin and postsynaptic density protein 95 genes in the prefrontal cortex. These results indicate that melatonin may provide protective effects against memory impairments associated with multiple sclerosis.<\/jats:p>","DOI":"10.31083\/j.jin.2020.02.32","type":"journal-article","created":{"date-parts":[[2020,7,1]],"date-time":"2020-07-01T07:12:20Z","timestamp":1593587540000},"source":"Crossref","is-referenced-by-count":33,"title":["Melatonin improves memory defects in a mouse model of multiple sclerosis by up-regulating cAMP-response element-binding protein and synapse-associated proteins in the prefrontal cortex"],"prefix":"10.31083","volume":"19","author":[{"given":"Badrah","family":"Saeed Alghamdi","sequence":"first","affiliation":[{"name":"Department of Physiology, Faculty of Medicine, King Abdulaziz University, Jeddah, 21589, Saudi Arabia"},{"name":"Neuroscience Unit, Faculty of Medicine, King Abdulaziz University, Jeddah, 21589, Saudi Arabia"},{"name":"Pre-Clinical Research Unit, King Fahad Medical Research Center, King Abdulaziz University, Jeddah, 21589, Saudi Arabia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hanin","family":"Abdulbaset AboTaleb","sequence":"first","affiliation":[{"name":"Department of Physiology, Faculty of Medicine, King Abdulaziz University, Jeddah, 21589, Saudi Arabia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"16242","published-online":{"date-parts":[[2020,6,30]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","unstructured":"Abo Taleb, H., A. and Alghamdi B.
