Abstract
CD13/aminopeptidase N (APN) is a multifunctional ectoenzyme that is involved in anti-inflammatory reactions, control of immune reactions and differentiation of many cellular systems. In this study, we first demonstrated that CD13/APN was expressed on human gingival fibroblast (hGF). T helper (Th) 2 cell type cytokines such as IL-4 and IL-13, but not IL-2 or IL-15, preferentially increased the expression of CD13/APN, resulting in the inhibition of FMLP-mediated neutrophil activation through the degradation by CD13/APN on HGF. Our data suggested that CD13/APN expressed by hGF could contribute to the anti-inflammatory response in periodontal tissue, and may be involved in disease processes mediated by Th2 cells.
