ARTEFACTS: How do we want to deal with the future of our one and only planet?

The European Commission’s Science and Knowledge Service, the Joint Research Centre (JRC), decided to try working hand-in-hand with leading European science centres and museums. Behind this decision was the idea that the JRC could better support EU Institutions in engaging with the European public. The fact that European Union policies are firmly based on scientific evidence is a strong message which the JRC is uniquely able to illustrate. Such a collaboration would not only provide a platform to explain the benefits of EU policies to our daily lives but also provide an opportunity for European citizens to engage by taking a more active part in the EU policy making process for the future. A PILOT PROGRAMME To test the idea, the JRC launched an experimental programme to work with science museums: a perfect partner for three compelling reasons. Firstly, they attract a large and growing number of visitors. Leading science museums in Europe have typically 500 000 visitors per year. Furthermore, they are based in large European cities and attract local visitors as well as tourists from across Europe and beyond. The second reason for working with museums is that they have mastered the art of how to communicate key elements of sophisticated arguments across to the public and making complex topics of public interest readily accessible. That is a high-value added skill and a crucial part of the valorisation of public-funded research, never to be underestimated. Finally museums are, at present, undergoing something of a renaissance. Museums today are vibrant environments offering new techniques and technologies to both inform and entertain, and attract visitors of all demographics.JRC.H.2-Knowledge Management Methodologies, Communities and Disseminatio

Kupffer Cells and Their Mediators : The Culprits in Producing Distant Organ Damage after Trauma-Hemorrhage

Posttraumatic activation of macrophages enhances development of systemic inflammation/immunosuppression and organ dysfunction. We hypothesized that Kupffer cells are the main source of monocyte chemoattractant protein-1 (MCP-1) production after trauma-hemorrhage, that administration of 17β-estradiol (E2) after trauma-hemorrhage modulates MCP-1 release and reduces remote organ damage, and that salutary effects of E2 are mediated via estrogen receptor (ER)-α. To test these hypotheses, female B57BL/J6 mice received E2 (50 μg/25 g) or vehicle after trauma-hemorrhage and female 129 Sve ER-β(−/−) transgenic mice and ovariectomized wild-type mice received E2 or ER-α agonist propyl pyrazole triol (50 μg/25 g) after trauma-hemorrhage. Systemic MCP-1 and interleukin-6 and their release by liver, spleen, and lung macrophages were determined by flow cytometry 4 hours after trauma-hemorrhage. Prior Kupffer cell depletion with gadolinium chloride significantly decreased systemic MCP-1 and interleukin-6 after trauma-hemorrhage and was associated with decreased edema/neutrophil infiltration in lung and liver. Kupffer cells were the only macrophages showing significant MCP-1 release, which was markedly reduced by E2 or propyl pyrazole triol in wild-type and in ER-β(−/−) mice. Pretreatment of mice with anti-MCP-1 antiserum prevented an increase in myeloperoxidase and edema in lung and liver. These findings suggest that Kupffer cell-derived MCP-1 plays a major role in remote organ dysfunction after trauma-hemorrhage
