The conditions leading to the activation/differentiation of T-helper (Th) cells dedicated for B-cell antibody production are still poorly characterized. We now demonstrate that interleukin-6 (IL-6) promotes the differentiation of naive T lymphocytes into helper cells able to promote B-cell activation and antibody secretion. IL-6-driven acquisition of B-cell help capacity requires expression of the signal transducer and activator of transcription 3 (STAT3), but not STAT4 or STAT6 transcription factors, suggesting that the ability to provide help to B cells is not restricted to a well-defined Th1 or Th2 effector population. T cell-specific STAT3-deficient mice displayed reduced humoral responses in vivo that could not be related to an altered expansion of CXCR5-expressing helper T cells. IL-6 was shown to promote IL-21 secretion, a cytokine that was similarly found to promote the differentiation of naive T cells into potent B-cell helper cells. Collectively, these data indicate that the ability to provide B-cell help is regulated by IL-6/IL-21 through STAT3 activation, independently of Th1, Th2, Th17, or follicular helper T cell (T(FH)) differentiation [less ▲]

Interleukin (IL)-6 has long been considered as an osteoresorptive factor. However, recent data indicate that IL-6 could influence bone formation in conditions of increased bone turnover. In this paper, the effects of IL-6 and its soluble receptor on osteoblast proliferation, differentiation and apoptosis are readdressed. A brief summary of IL-6 signaling after binding to its receptor is provided and hypotheses concerning IL-6 and the central control of bone formation are also highlighted. (c) 2005 Elsevier Inc.

A central question in health hazard associated with environmental pollution is the evaluation of level of exposure to a mixture of carcinogens and the estimation of the global health impact on the residents. The point is important to found a public health decision for site intervention or residents relocalisation. Belgium had to face such a problem at Mellery, a village which became internationally famous some years ago, when local residents denonced a local pollution originating from an industrial waste depository facility situated only 500 m from the centre of their village, in a former sand quarry. A central piece of the actions of the authorities was the original campaign organised to measure directly the level of exposure to carcinogens of a large group of voluntary local residents, children included, by measuring biomarkers of exposure in blood lymphocytes : for its high sensitivity, the frequency of sister chromatid exchanges (SCES) had been chosen. This biomonitoring method, quite commonly used to monitor occupational environment, had never before been applied to evaluate the potential health impact of the environment on a general population. Such data, although sophisticate and integrative, are only indicators of exposure and cannot be used, so far, as individual quantitative predictors of the possible evolution of the health of the individual persons. First designed as an epidemiological study, the campaign at Mellery revealed so high exposure levels that the experts did not keep with the original experimental line and decided to release individual information to the concerned persons, without much preparation nor risk communication policy. Several groups (experts, local doctors, local and regional authorities, public agencies and residents associations) were active integrating the information in their respective discourses, giving them specific interpretative and competing meanings. Any scenario for intervention had to be embedded in some meaningful and legitimating discourse : a quite difficult task for the authorities. The evolution of the expertise system used for public decision-making were marked by several such uncertainties (geological, biological, medical) but also by the difficult integration of health related aspects within environment interventions in the regulatory structures in Belgium : health responsibilities are scattered between federal and "communautaire" bodies, while most of the environmental actions are funded at the regional level. In this first heavy case, the young regional institutions reacted in a disorganized manner: they choose to not put at risk their frail power equilibrium and to not reconsider the attribution of the responsibilities. The authors propose to analyse how peculiar interlocking of the biological and political uncertainties were at the core of the general failure in public risk management around this landfill site: Mellery, after 10 years and a huge budget for site treatment, is still a nightmare for environmental authorities in Southern Belgium.

Architecture is often perceived as "not pure". Too much or not enough, It resists in many rankings. But this fundamental indeterminacy can be seen as an obstacle to the rationality or becoming itself a real subject of research. We believe that architecture can help other disciplines' researchers to interrupte their "dogmatic slumber." [less ▲]
