Meteorin-like Levels in Individuals With Periodontitis

Study Overview
=================
Brief Summary
-----------------
Metrnl has proven to be an inflammatory-related immunoregulatory cytokine and shown to play a role in the pathogenesis of human inflammatory diseases. Metrnl is highly expressed from the oral mucosa to the esophagus. Periodontitis is a chronic inflammatory disease that can start with localized inflammatory reactions created by the supporting tissues surrounding the teeth against microorganisms and then result in loss of teeth. The authors think that Metrnl may play a role in the periodontitis. The aim of this study is to compare the Metrnl, TNF-α, IL-1β, TGF-β, IL-10 and VEGF levels of healthy and periodontitis individuals.

Detailed Description
-----------------
Periodontitis is a destructive chronic inflammatory disease that can start with localized inflammatory reactions created by the supporting tissues surrounding the teeth against microorganisms and then result in loss of teeth. Cytokines play an important role in inflammation that occurs in periodontal disease. Tumor Necrosis Factor-α (TNF-α), Interleukine -1β ( IL-1β )and Interleukine-6 (IL-6), Prostaglandin E2 (PGE2) and Interferon gamma (IFN- γ) levels are associated with periodontal destruction in the pathogenesis of periodontal disease. Vascular endothelial growth factor (VEGF) are important features of inflammation, wound healing and bone healing. Cytokines such as Interleukine-10 (IL-10) and transforming growth factor- β (TGF-β) have been reported to decrease periodontal disease progression rate. Gingival crevicular fluid shows the cellular response in the periodontium. The most important host-related ingredients are inflammatory markers, including cytokines, enzymes, and interleukins. Saliva analysis is used in the diagnosis of systemic conditions as well as in the diagnosis of oral pathologies. Meteorin- like (Metrnl) is a protein that plays a role in natural and acquired immune-related functions and inflammatory responses, and expressed in barrier tissues (skin and mucosa) as well as various macrophage populations, from dendritic cells and some granulocytes. Metrnl has proven to be an inflammatory-related immunoregulatory cytokine and shown to play a role in the pathogenesis of human inflammatory diseases. Metrnl, which is highly expressed from the oral mucosa to the esophagus, may play a role in the onset of periodontitis and an effective marker in preventing the progression of destruction. We think that Metrnl plays an important role in periodontitis, an inflammatory disease. The aim of this study is to compare the Metrnl, TNF-α, IL-1β, TGF-β, IL-10 and VEGF levels of healthy and periodontitis individuals
