Glucagon-Like Peptide-1 Receptor Agonist Liraglutide Ameliorates the Development of Periodontitis

Figure 1

Histological evaluation of the gingiva. Liraglutide decreased the inflammatory cell invasion in periodontitis. (a) Schematic images of periodontal tissue with (periodontitis) and without (normal) ligation. The squares represent the parts shown in the below figures. (b) Upper panels: H&E staining of the periodontal tissues around the tooth 14 days after ligation. Lower panels: detection of iNOS-positive inflammatory cells in the gingiva. The black arrows mark iNOS-positive inflammatory cells. 0 μm. (c) Quantification of iNOS-positive inflammatory cells in the gingiva. The results are expressed as the (). and .
