The immunoresponsive gene 1 （IRG 1） protein has crucial functions in embryonic implantation and neurodegeneration. IRG1 promotes endotoxin tolerance by increasing A20 expression in macrophages through reactive oxygen species （ROS）. The cytoprotective protein heme oxygenase-1 （HO-1）, which generates endogenous carbon monoxide （CO）, is expressed in the lung during Lipopolysaccharide （LPS） tolerance and cross tolerance. However, the detailed molecular mechanisms and functional links between IRG1 and HO-1 in the innate immune system remain unknown. In the present study, we found that the CO releasing molecule-2 （CORM-2） and chemical inducers of HO- 1 increased I RG 1 expression in a time- and dose-dependent fashion in RAW264.7 cells. Furthermore, inhibition of HO-1 activity by zinc protoporphyrin IX （ZnPP） and HO-1 siRNA significantly reduced expression of IRG1 under these conditions. In addition, treatment with CO and HO-1 induction significantly increased A20 expression, which was reversed by ZnPP and HO-1 siRNA. LPS-stimulated TNF-a was significantly decreased, whereas IRG1 and A20 were increased by CORM-2 application and HO-1 induction, which in turn were abrogated by ZnPP. Interestingly, siRNA against IRG1 and A20 reversed the effects of CO and HO-1 on LPS-stimulated TNF-a production. Additionally, CO and HO-1 inducers significantly increased IRG1 and A20 expression and downregulated TNF-a production in a LPS-stimulated sepsis mice model. Furthermore, the effects of CO and HO-1 on TNF-α production were significantly reversed when ZnPP was administered. In conclusion, CO and HO-1 induction regulates IRG1 and A20 expression, leading to inhibition of inflammation in vitroand in an in vivomice model.

Carbon monoxide （CO） can act as an anti-inflammatory effector in mouse models of lung injury and disease, through the downregulation of pro-inflammatory cytokines production, though the underlying mechanisms remain unclear. The nucleotide-binding oligomerization domain-, leucine-rich region-, and pyrin domain-containing-3 （NLRP3） inflammasome is a protein complex that regulates the maturation and secretion of pro-inflammatory cytokines, including interleukin-1β （IL-1β）. In this report, we show that the CO-releasing molecule （CORM-2） can stimulate the expression of pyrin, a negative regulator of the NLRP3 inflammasome. CORM-2 increased the transcription of pyrin in the human leukemic cell line （THP-1） in the absence and presence of lipopolysaccharide （LPS）. In THP-1 cells, CORM-2 treatment dose-dependently reduced the activation of caspase-1 and the secretion of IL-lp, and increased the levels of IL-IO, in response to LPS and adenosine 5＇-triphosphate （ATP）, an NLRP3 inflammasome activation model. Genetic interference of IL-10 by small interfering RNA （siRNA） reduced the effectiveness of CORM-2 in inhibiting IL-1β production and in inducing pyrin expression. Genetic interference of pyrin by siRNA increased IL-lp production in response to LPS and ATP, and reversed CORM-2-dependent inhibition of caspase-1 activation. CO inhalation （250 ppm） in vivo increased the expression of pyrin and IL-10 in lung and spleen, and decreased the levels of IL-1β induced by LPS. Consistent with the induction of pyrin and IL-10, and the downregulation of lung IL-1β production, CO provided protection in a model of acute lung injury induced by intranasal LPS administration. These results provide a novel mechanism underlying the anti-inflammatory effects of CO, involving the IL-10-dependent upregulation of pyrin expression.

Background: Four factors determine the quality of an implantology kit: 1) Heat generated by the drills;2) Morphology of the osteotomy according to the diameter of the implant;3) Efficiency of collecting autologous bone;and 4) Osteotomy execution time. Materials and Methods: This article examines the heat produced by drills during osteotomy, focusing on the effect of the following factors: drilling technique;volume of autologous bone harvested;drilling time;implant primary stability;and the percentage of osseointegrated implants after primary healing. Discussion: The four factors mentioned above are analyzed based on the data obtained for sequential, biological, and One Drill milling techniques. Conclusions: 1) One Drill is the fastest technique for performing the osteotomy;2) All techniques stay within the biological temperature range of living bone, with the lowest increase in temperature achieved using One Drill with irrigation;3) The bone harvested showed no statistically significant differences between biological milling and the One Drill technique, both far superior to the sequential technique;and 4) There is no statistically significant difference in the number of osseointegrated implants among the three techniques analyzed.
