IL-32 Isoforms Levels in GCF and Plasma of the Patients With Periodontitis

Interleukin (IL)-32, which has been recently reported to be associated with periodontitis, has been suggested to have pleiotropic effect due to its 9 different isoforms. The aim of this study was to investigate the levels of IL-32α, IL-32β, IL-32γ, IL-32δ isoforms in gingival crevicular fluid (GCF) and plasma before and after nonsurgical periodontal treatment in patients with periodontitis (P).Twenty-seven P and 27 periodontally healthy controls (C) were recruited in this study. Periodontitis patients were performed nonsurgical periodontal treatment. GCF and plasma sampling and clinical periodontal parameters were evaluated before and 1 month after treatment. Enzyme-linked immunosorbent assay was used to analyze the levels of IL-32α, IL-32β, IL-32γ, IL-32δ isoforms in GCF and plasma samples.
