Guidance Document for Executive Order Number 17, March 25, 2010

Executive Order 17, signed by Governor Chester J. Culver on September 25, 2009, emphasizes revitalization of historic properties and cultural and entertainment districts and also supports safe and healthy work places, sustainable design and cost effective use of state resources. Specifically, the Executive Order requires that State entities managing or leasing real estate on behalf of the State shall give priority to the needs of public entities and the populations they serve consistent with the cost effective use of state revenues. It also indicates that existing resources and facilities shall be used where adequate, cost competitive and appropriate for efficient and effective current state operations.

The roles of granulocyte-macrophage colony-stimulating factor and interleukin 3 in stromal cell-mediated hemopoiesis in vivo.

Adherent cells from murine long-term marrow cultures (LTMC) were examined for presence of mRNA for granulocyte-macrophage colony-stimulating factor (GM-CSF) and interleukin 3 (Il-3). Six hours after medium replacement, GM-CSF mRNA was detected but was no longer detectable 24 h after feeding; Il-3 mRNA was not detected at any time. Neutralizing antibodies against these factors had no effect on hemopoiesis. Exogenous Il-3 increased cell production, notably mature erythroid progenitors, whereas GM-CSF had little long-term effect even at high concentrations. Furthermore, GM-CSF appeared to be specifically removed from the medium, whereas virtually all of the Il-3 could be recovered under identical incubation conditions. These results show that Il-3 is not required for maintaining long-term hemopoiesis in vitro, whereas the precise role of GM-CSF in this system remains unclear.

The Role of Interleukin-2 in Memory CD8 Cell Differentiation

The current literature on the role of interleukin (IL)-2 in memory CD8(+) T-cell differentiation indicates a significant contribution of IL-2 during primary and also secondary expansion of CD8(+) T cells. IL-2 seems to be responsible for optimal expansion and generation of effector functions following primary antigenic challenge. As the magnitude of T-cell expansion determines the numbers of memory CD8(+) T cells surviving after pathogen elimination, these events influence memory cell generation. Moreover, during the contraction phase of an immune response where most antigen-specific CD8(+) T cells disappear by apoptosis, IL-2 signals are able to rescue CD8(+) T cells from cell death and provide a durable increase in memory CD8(+) T-cell counts. At the memory stage, CD8(+) T-cell frequencies can be boosted by administration of exogenous IL-2. Significantly, only CD8(+) T cells that have received IL-2 signals during initial priming are able to mediate efficient secondary expansion following renewed antigenic challenge. Thus, IL-2 signals during different phases of an immune response are key in optimizing CD8(+) T-cell functions, thereby affecting both primary and secondary responses of these T cells.

Interleukin-1 receptor antagonist gene (IL-1RN) polymorphism is a predictive factor of clinical pregnancy after IVF.

BACKGROUND: Only 25% of IVF transfer cycles lead to a clinical pregnancy, calling for continued technical progress but also more in depth analysis of patients' individual characteristics. The interleukin-1 (IL-1) system and matrix metalloproteinases (MMPs) are strongly implicated in embryo implantation. The genes coding for IL-1Ra (gene symbol IL-1RN), IL-1beta, MMP2 and MMP9 bear functional polymorphisms. We analysed the maternal genetic profile at these polymorphic sites in IVF patients, to determine possible correlations with IVF outcome. METHODS: One hundred and sixty women undergoing an IVF cycle were enrolled and a buccal smear was obtained. The presence of IL-1RN variable number of tandem repeats and IL-1B + 3953, MMP2-1306 and MMP9-1562 single nucleotide substitutions were determined. Patients were divided into pregnancy failures (119), biochemical pregnancies (8) and clinical pregnancies (33). RESULTS: There was a 40% decrease in IL-1RN*2 allele frequency (P = 0.024) and a 45% decrease in IL-1RN*2 carrier status in the clinical pregnancy group as compared to the pregnancy failure group (P = 0.017). This decrease was still statistically significant after a multivariate logistic regression analysis. The likelihood of a clinical pregnancy was decreased accordingly in IL-1RN*2 carriers: odds ratio = 0.349, 95% confidence interval = 0.2-0.8, P = 0.017. The IL-1B, MMP2 and MMP9 polymorphisms showed no correlation with IVF outcome. CONCLUSIONS: IL-1RN*2 allele carriage is associated with a poor prognosis of achieving a pregnancy after IVF.
