ABSTRACT
<p><b>OBJECTIVE</b>To investigate the influence of carbon monoxide on the expression of adhesion molecules stimulated by inflammatory cytokines on human gingival fibroblasts.</p><p><b>METHODS</b>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.</p><p><b>RESULTS</b>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.</p><p><b>CONCLUSION</b>Carbon monoxide could be a promising way in treating of periodontitis.</p>
