Background: Neopterin, a marker of cellular immune activation, is produced by human macrophages after induction by interferon gamma that is secreted by T lymphocytes. Neopterin concentrations in diverse body fluids have been reported to increase in parallel with bacteria in the clinical course of infections. Therefore, determination of neopterin in body fluids was thought to be useful for predicting the prognosis and diagnosis of aggressive forms of periodontal disease, in which the cell-mediated immune response plays an important role in immunopathogenesis. The aim of the present study was to observe the role of neopterin in the pathogenesis of aggressive periodontitis (AgP).
