Galbanic acid delays the development of seizures by modulating the expression of TNFα, IL1β, and TLR4 genes and reducing hippocampal nitrite levels and may be useful in the treatment of epilepsy

Introduction and Objective

Epilepsy is one of the most common chronic brain disorders worldwide. This study aimed to determine the effect of Galbanic acid on seizures.

Materials and Methods

In this study, 40 NMRI mice were used and divided into 4 groups. The control group received 10 mg/kg normal saline. Three groups received Galbanic acid at doses of 10, 20, and 40 mg/kg. The positive control group received diazepam with a dose of 10 mg/kg. All injections were made intraperitoneally for one week. Seizures were induced in all mice by injection of 90 mg/kg Pentylenetetrazole (PTZ). Then the latency of seizure onset in each of the experimental groups was recorded. After anesthesia with Ketamine 100 mg/kg and Xylazine 10 mg/kg, blood samples were taken and after decapitation, the hippocampus was isolated and the expression of αTNF-, IL1β, and TLR4 genes in this region was measured.

Results

Galbanic acid increased the delay in seizure onset, decreased brain and serum nitrite levels, and decreased the expression of αTNF-, IL1β, and TLR4 genes in brain tissue compared to the control group (P < 0.01, p < 0.001).

Conclusion

Galbanic acid reduced nitrite and the expression of αTNF-, IL1β, and TLR4, leading to a decrease in neuroinflammation and, as a result, a delay in seizure onset in mice.

期刊介绍： Neuroscience Letters is devoted to the rapid publication of short, high-quality papers of interest to the broad community of neuroscientists. Only papers which will make a significant addition to the literature in the field will be published. Papers in all areas of neuroscience - molecular, cellular, developmental, systems, behavioral and cognitive, as well as computational - will be considered for publication. Submission of laboratory investigations that shed light on disease mechanisms is encouraged. Special Issues, edited by Guest Editors to cover new and rapidly-moving areas, will include invited mini-reviews. Occasional mini-reviews in especially timely areas will be considered for publication, without invitation, outside of Special Issues; these un-solicited mini-reviews can be submitted without invitation but must be of very high quality. Clinical studies will also be published if they provide new information about organization or actions of the nervous system, or provide new insights into the neurobiology of disease. NSL does not publish case reports.
