RESUMO
Autonomic nervous system (ANS) imbalances are involved in the etiology of cancer, allergy, and collagen diseases. Previously, we hypothesized that FoxO and HSF-1 limit autonomic stress responses via negative feedback on the ANS. Here, we evaluated the role of AKT, a negative regulator of FoxO, during activation of the ANS by loneliness stress in mice. Spontaneous motility was increased during loneliness stress and decreased after release from stress. The AKT activator SC79 attenuated stress-induced spontaneous motility, whereas the AKT inhibitor API-2 prevented decreases in motility after stress release. Our results show that AKT activity regulates ANS responses to loneliness stress.
