Our results demonstrate that IL-6 is a key mediator of erythropoietic collapse during T. gondii infection and that BMSCs may be the relevant source of IL-6. This study also suggests that the bone marrow stroma is functionally different during an immune response, and that BMSCs are potential mediators of changes in HP composition as a consequence of inflammation.

SA0184 Human Blood Eosinophils: An Extrarenal Source of Converting Inactive Vitamin D to Its Active Form and Potential Role in Inflammation.Devendra Agrawal*1, Divya Pankajakshan1, J. Christopher Gallagher2. 1Creighton University School of Medicine, USA, 2Creighton University Medical Center, USA Rationale: Vitamin D, especially its most active metabolite 1,25-dihydroxyvitamin D3 or calcitriol, is essential in regulating calcium http://www.selleckchem.com/products/obeticholic-acid.html homeostasis, immune modulation, cell proliferation and differentiation. Although extra-renal synthesis of calcitriol associated with inflammatory diseases is known to occur in macrophages and epithelial cells, little is known on the existence of enzymes involved in vitamin D synthesis and metabolism in circulating immune cells. In this study, we examined such enzymes in human blood eosinophils and also investigated the effect of calcitriol, administered in vivo or added exogenously, on the expression of intracellular molecules involved in inflammation in purified white blood cells (WBCs). Methods: Peripheral blood was drawn from healthy volunteers and WBCs were purified http://www.selleckchem.com/products/Adriamycin.html (purity >97%; viability >98%) and stimulated in vitro with calcitriol (100 nM) for 24 hrs. We also purified WBCs from the blood of vitamin D-deficient (25-OHD levels
