Background & Objective: Aging brings with it its own age concerns; they are often associated with stress and the development of emotional issues such as anxiety and depression. Many authors have described stress as a possible trigger for the development of a series of psychiatric and metabolic pathologies, and the hormone cortisol at high levels seems to be the link between stress and the development of dysfunctions. In view of the context already presented that older people, due to biological and psychosocial issues, are more stressed, that stress is a trigger for chronic diseases and that this population in most cases consumes a great quantity of drugs, it is justified the search for nutritional elements that can contribute to the fight against stress. One of the potent nutritional elements is a much-consumed fruit in America's avocado (Persea americana). It contains a rich nutritional matrix with functional properties, which makes it relevant to carry out in vitro studies on the potential effect of supplementation with avocado oil in a stress neuronal model. Therefore, the objective of this study was to evaluate in vitro, the potential neuroprotective effect of avocado against neural aged-cells (SH-SY5Y) exposed to cortisol. Methods: The effect of supplementation of SH-SY5Y neural cell culture with avocado pulp oil exposed to cortisol was evaluated. The following parameters were analyzed in 24 and 72 hours: viability, rate of cell proliferation and variables associated with oxidative stress and apoptotic markers. Results: Avocado showed a protective effect against exposure of neural cells to cortisol. Increasing their viability and proliferation and reversing apoptosis caused by cortisol, observed in the decline of the protein levels of BAX, BCL-2 and caspase 3 and 8, as well as the genotoxic effect observed on 8-hydroxy-2'-deoxyguanosine as an increase in antioxidant enzymes such as SOD, CAT and GPX. Conclusion: Despite the methodological in vitro protocol limitations, results suggested that avocado oil could have neuroprotective effect against neural aged-cells exposed to cortisol. These data could be relevant to development of a supplement that helps to decrease stress consequences, mainly in the elderly.
