| Hazard Information | Back Directory | [Uses]
Exendin (5-39) is a potent glucagon-like peptide 1 (GLP-1) receptor antagonist. Exendin (5-39) improves memory impairment in β-amyloid protein-treated rats[1]. | [in vivo]
Exendin (5-39) (intracerebroventricular injection; 0.3 μg; once daily; 1-week) increases GLT-1 protein levels in the hippocampus of male Wistar rats. Additionally, hippocampal slices are prepared from Ex-treated or vehicle rats,Exendin (5-39) decreases fEPSP decay time and increases the input-output relation and decreased the paired-pulse ratio in the dentate gyrus (DG). Furthermore, Ex inhibits long-term depression but not long-term potentiation in the DG[1]. | Animal Model: | Wistar rats (3 weeks old and 18 days pregnant)[1] | | Dosage: | 0.3 μg | | Administration: | Intracerebroventricular injection; 0.3 μg; once daily; 1-week | | Result: | Inhibited GLT-1 protein levels and inhibited long-term depression in rats.
