Abstract
The major goal of this study was to evaluate the influence of gangliosides (GANG) treatment on the onset of adaptive changes and the sequelae induced by stress exposure. With this purpose, the behavioral response to 5-methoxy-N,N-dimethyltryptamine (5-MeODMT, 5 mg/kg, IP) and motor activity were evaluated in rats previously submitted either to a single restraint session (2 h) or to a daily restraint event for 3 consecutive days, combined or not to GANG administration (30 mg/kg IP). GANG was always injected 2 h before stress exposure. In addition, differences in body weights were recorded throughout the experiments. A similar behavioral response after 5-MeODMT was observed between saline (SAL) and GANG unstressed rats. Exposure to one or three restraint sessions did not modify the behavioral response to 5-MeODMT, whereas the association of GANG and stress during 3 consecutive days enhanced forepaw treading and hindlimb abduction. SAL-treated animals submitted to a single or to three stressful stimuli showed reduced locomotion and rearing. The combination of GANG and stress for 3 days, but not after a unique association, reversed the decrease on motor activity induced by the aversive experience. The decrease of body weights produced by one or three stress sessions was recovered only in animals treated with GANG and stress for 3 days. These findings suggest that GANG may accelerate the onset of adaptive changes on 5-HT1 sites and attenuate certain sequelae induced by previous stress experience.
