Therapeutic effects of peptide P140 in a mouse periodontitis model.

ABSTRACT: In our search for innovative drugs that could improve periodontal treatment outcomes, autophagy and its anomalies represent a potential target for therapeutic intervention. We sought to identify autophagy defects in murine experimental periodontitis and study the effectiveness of P140, a phosphopeptide known to bind HSPA8 and inhibit its chaperone properties, and that corrects autophagy dysfunctions in several autoimmune and inflammatory diseases. Experimental periodontitis was induced by placing silk ligature around mandibular first molars. Sick mice were treated intraperitoneally with either P140 or a control, scrambled peptide. After 10 days, mandibles were harvested and bone loss was measured by micro-CT. Immune cells infiltration was studied by histological analyses. Cytokines levels
