IL-10 and IL-10 receptor overexpression in oral giant cell lesions

2010

Objective: Central giant cell lesions (CGCL) and peripheral giant cell lesions (PGCL) occur in the jaws and contain osteoclast-like giant cells and mononuclear cells positive for the macrophage marker CD68. The participation of immune-inflammatory mechanisms has been proposed in the lesions development. As IL-10 is one of the most important anti-inflammatory cytokines and it is also an inhibitory cytokine to macrophage function and bone resorption, the purpose of the present study was to investigate its expression together with its receptor (IL-10R?) in CGCL and PGCL. Study Design: Six fragments of CGCL and seven fragments of PGCL were obtained by surgical excision. Frozen specimens were cu…
