Saliva levels of 3 antimicrobial peptides (HNP 1-3, LL-37, and S100) derived from epithelial and neutrophils are also elevated in patients with Behcet’s disease, a chronic inflammatory disease associated with systemic vascular inflammation [117], and HNP 1-3 and LL-37 levels exhibited an association with disease severity, perhaps reflecting the elevated level of enhanced local and systemic innate immune responses in Behcet’s disease [118]. Here, CAMP is linked to Behcet disease.
