Exacerbation of CNS inflammation and neurodegeneration by systemic LPS treatment is independent of circulating IL-1β and IL-6

<p>Abstract</p> <p>Background</p> <p>Chronic neurodegeneration comprises an inflammatory response but its contribution to the progression of disease remains unclear. We have previously shown that microglial cells are primed by chronic neurodegeneration, induced by the ME7 strain of prion disease, to synthesize limited pro-inflammatory cytokines but to produce exaggerated responses to subsequent systemic inflammatory insults. The consequences of this primed response include exaggerated hypothermic and sickness behavioural responses, acute neuronal death and accelerated progression of disease. Here we investigated whether inhibition of systemic cytokine synthesis using the anti-inflammatory steroid dexamethasone-21-phosphate was sufficient to block any or all of these responses.</p> <p>Methods</p> <p>ME7 animals, at 18-19 weeks post-inoculation, were challenged with LPS (500 μg/kg) in the presence or absence of dexamethasone-21-phosphate (2 mg/kg) and effects on core-body temperature and systemic and CNS cytokine production and apoptosis were examined.</p> <p>Results</p> <p>LPS induced hypothermia and decreased exploratory activity. Dexamethasone-21-phosphate prevented this hypothermia, markedly suppressed systemic IL-1β and IL-6 secretion but did not prevent decreased exploration. Furthermore, robust transcription of cytokine mRNA occurred in the hippocampus of both ME7 and NBH (normal brain homogenate) control animals despite the effective blocking of systemic cytokine synthesis. Microglia primed by neurodegeneration were not blocked from the robust synthesis of IL-1β protein and endothelial COX-2 was also robustly synthesized. We injected biotinylated LPS at 100 μg/kg and even at this lower dose this could be detected in blood plasma. Apoptosis was acutely induced by LPS, despite the inhibition of the systemic cytokine response.</p> <p>Conclusions</p> <p>These data suggest that LPS can directly activate the brain endothelium even at relatively low doses, obviating the need for systemic cytokine stimulation to transduce systemic inflammatory signals into the brain or to exacerbate existing pathology.</p

Who benefits and how? Public expectations of public benefits from data-intensive health research

The digitization of society and academic research endeavours have led to an explosion of interest in the potential uses of population data in research. Alongside this, increasing attention is focussing on the conditions necessary for maintaining a social license for research practices. Previous research has pointed to the importance of demonstrating “public benefits” from research for maintaining public support, yet there has been very little consideration of what the term “public benefits” means or what public expectations of “public benefits” are. In order to address this pressing issue a series of deliberative workshops with members of the public were held across Scotland in May and June 2017. The workshops aimed to engage a cross-section of the Scottish population in in-depth discussions of the ways that the public – or publics – might benefit from data-intensive health research. The findings reported here discuss workshop participants’ understandings and expectations of health research; who they considered to be “the public” that should benefit from health research and; in what ways they felt “the public” should benefit. Workshop participants’ preference was clearly for the widest possible public benefit to be felt by all, but they also acknowledged the value in research aiming to primarily benefit vulnerable groups within society. A key focus of discussions was the extent to which workshop participants were confident that potential public benefits would be realised. A crucial consideration then is the extent to which mechanisms and political support are in place to realise and maximise the public benefits of data-intensive health research

Jamaican Universities Aiding the Design of an Urban Public Space

Many governments are actively seeking solutions to address the economic crises bedeviling their countries. University/college towns have proven to be successful models of opportunities for attracting investments for economic development while at the same time promoting optimal health outcomes. Harvard, MIT and Newcastle universities provide examples of successful models of universities aiding in spatial design and planning of towns or neighborhoods where they are located to yield sustainable development. The Government of Jamaica has supported the proposal from the University of Technology, Jamaica, (UTech, Jamaica Ja.) to redesign the Papine area in St. Andrew into a university town, given its proximity to the two largest universities in Jamaica, UTech, Ja. and the University of the West Indies (UWI). Both institutions collaborated by using cutting-edge scholarly research and design approaches to propose workable solutions that can promote economic development and healthy lifestyle in an area designated as a university town. The research found that SOPARC was a feasible and reliable instrument for assessing park user variables and associated contextual variables. However, for the proposed design to be executed and maintained, the study recommends establishing a body such as a University District/Town Council with oversight responsibility for planning and land use management of the area
