The function of NK cells was also improved as shown by an increase in IFN-γ secretion and cytotoxic activity against an HPV+ cell line. This crosstalk between NK cells and DCs needed CD40 interaction and IL-12p70 secretion, whereas NKG2D was not implicated. Our results provide insight into how VLPs interact with innate immune cells and how NK cells and DCs play a role in the immune response induced by this vaccine agent. “
“Citation Sharma D, Singh A, Trivedi SS, Bhattacharjee J. Role of endothelin and inflammatory cytokines in pre-eclampsia – a pilot north Indian study. Am J Reprod Immunol 2011; 65: 428–432 Problem  Pre-eclampsia is new onset hypertension

during pregnancy with proteinuria. The initiating event in pre-eclampsia is postulated to involve reduced Selumetinib nmr placental perfusion, which leads

to widespread dysfunction of the maternal vascular endothelium. Cytokines also appear to contribute to the development of the pathological condition. The aim of this study was to evaluate the role of cytokines in pre-eclampsia and to study the relationship between endothelin-1 and cytokines with the severity of the disease. Method of study  This cross-sectional study included 300 women with pre-eclampsia and 200 healthy pregnant women. Their blood samples were analyzed for endothelin-1 and inflammatory cytokines. Results  Increased endothelin-1 and cytokines [tumor necrosis factor-α, interleukin-2 (IL-2) and γ-interferon (IFN-γ)] levels were found in pre-eclampsia (P < 0.001). Significant positive correlation was seen between endothelin-1 and cytokine level (IL-2 KPT-330 cost and IFNγ) in the pre-eclamptic group (P = 0.001). Conclusion  We conclude that pre-eclampsia is associated with increased levels of both endothelin-1 and circulating inflammatory cytokines, which points toward the role of endothelial and inflammatory components. “
“Research on infectious diseases DNA ligase using animal models has been a successful example of translational research. However, because chronic infections are

still one of the main causes of death and disability in the world, it is expected that a great number of mice will continue to be used to address this subject. Although increasing awareness regarding animal welfare has led to novel recommendations for animal housing enrichment, studies evaluating the impact of these modifications on the immune response to infection are lacking. The present study shows that validated and recommended simple environmental enrichment does not interfere with the immune response to chronic infection with Mycobacterium avium for up to 20 weeks, as assessed by the bacterial load in the spleen and lung, by the number and activation status of the main cell populations of the immune system and the serum concentration of interferon-gamma. Therefore, enrichment can be encouraged without concern regarding comparability of results among laboratories studying this type of chronic infections.
