Effects of Serotonergic Compounds on Stress-Induced Behavior in Rats.
Abstract
Because our earlier experiments with fenfluramine and serotonin antagonists did not provide encouraging results, we decided to study effects of endotoxin (lipopolysaccharide, LPS) and interleukin- 1, (IL-1) which are known to reduce food intake, and which we have shown also alter cerebral serotonergic and noradrenergic metabolism. Thus it is possible that there is a relationship between the activation of these cerebral neurotransmitter systems and the hypophagia. Specifically, it can be hypothesized that LPS- and IL-1-induced hypophagia are related to the increased noradrenergic and serotonergic activity. This hypothesis has been tested using a variety of neurotransmitter receptor antagonists for their ability to antagonize LPS- or IL-1-induced hypophagia in mice. Several behavioral experiments were completed.
