One of the main histopathological hallmarks of\n                    <jats:sc>AD<\/jats:sc>\n                    is the deposition of amyloid plaques in the brain. Despite some epidemiological studies demonstrating that cigarette smoke is a factor in predisposing people to\n                    <jats:sc>AD<\/jats:sc>\n                    , nicotine, the principal alkaloid of\n                    <jats:italic>Nicotiana Tobacco<\/jats:italic>\n                    , has been widely studied for its ability to improve cognitive performance, both in animal models and in human studies. Several hypotheses have been proposed to explain the mechanism of action underlying the beneficial effect of nicotine in\n                    <jats:sc>AD<\/jats:sc>\n                    ; however, this is still questioned. To gain new insights into the molecular mechanism underlying nicotine's neuroprotective action in\n                    <jats:sc>AD<\/jats:sc>\n                    , we performed NMR metabolomics on SH\u2010SY5Y neuroblastoma cells treated with A\u03b2(1\u201342) in the presence of nicotine. Our data show that the neuroprotective action of nicotine resides in its ability to restore the systemic unbalanced metabolism associated with\n                    <jats:sc>AD<\/jats:sc>\n                    . In particular, nicotine reverses most A\u03b2(1\u201342)\u2010induced metabolic impairments, including those related to amino acid metabolism, especially neurotransmission, as well as alterations in energy and membrane phospholipid metabolism.\n
