title: [Influence of carbon monoxide on the expression of adhesion molecules stimulated with tumor necrosis factor-alpha and interleukin-1beta on human gingival fibroblasts].
abstract: OBJECTIVE
  To investigate the influence of carbon monoxide on the expression of adhesion molecules stimulated by inflammatory cytokines on human gingival fibroblasts.
  
  
  METHODS
  Human gingival fibroblasts were stimulated with 50 ng x mL(-1) tumor necrosis factor (TNF)-alpha and 10 ng x mL(-1) interleukin (IL)-1beta concurrently in the presence or absence of 500 micromol x L(-1) carbon monoxide releasing molecule (CORM). Expression of intercellular adhesion molecule (ICAM)-1, vascular cell adhesion molecule (VCAM)-1 at protein and mRNA level was examined by Western blot and reverse transcription polymerase chain reaction (RT-PCR), respectively. Activity of transcription factor NF-kappaB was evaluated by reporter gene assay.
  
  
  RESULTS
  Expression of ICAM-1 and VCAM-1 on human gingival fibroblasts increased dramatically after concurrent stimulation of TNF-alpha and IL-1beta, while CORM inhibited the upregulation of ICAM-1 and VCAM-1. CORM decreased the activity of NF-KB stimulated by TNF-alpha and IL-1beta.
  
  
  CONCLUSIONS
  Carbon monoxide could be a promising way in treating of periodontitis.
