Do tumor necrosis factor-α and Porphyromonas gingivalis lipopolysaccharides decrease periostin in human periodontal ligament fibroblasts?
Inflammatory mediators (TNF-α) and bacterial virulence factors (P. gingivalis LPS) decrease periostin expression in human PDL fibroblasts. These results support a potential mechanism by which periostin alterations could act as a contributing factor during periodontal disease progression.
Hepatic steatosis in children is positively associated with circulating levels of PAI-1 independent of body mass index, insulin resistance, and inflammatory markers. Further studies are needed to clarify the potential role of PAI-1 as a therapeutic target in pediatric nonalcoholic fatty liver disease.
