Secretory leukocyte protease inhibitor regulates human periodontal ligament cell production of pro-inflammatory cytokines
Objective: Regulation of immune-like cell properties of periodontal ligament (PDL) cells is not understood. We investigate the importance of secretory leukocyte protease inhibitor (SLPI) for production of pro-inflammatory cytokines in human PDL cells. Materials and methods: PDL cells were isolated from teeth extracted for orthodontic reasons. Cellular location of SLPI was investigated by immunocyt
