Objective: To determine if local reactivation of antigen-specific oral CD8+ TRM exacerbates ligature-induced periodontitis (LIP) in mice.
Summary: Topical application of virus-mimicking peptides during LIP increased alveolar bone loss, enhanced gingival and cervical lymph node inflammation, and upregulated gingival genes linked to innate immunity and cytotoxicity. Depleting CD103+ CD8+ TRM with αCD103-SAP prior to LIP prevented disease exacerbation, implicating these cells in periodontitis pathology.
Usage: Anti-CD103-SAP (IT-50) was administered in PBS at 5 μg (day -4), 2 μg (day 0), and 2 μg (day +4) relative to LIP induction.
