Septic shock, the most severe problem of sepsis, is a lethal condition caused by the interaction of a pathogen-induced long chain of sequential intracellular events in immune cells, epithelium, endothelium, and the neuroendocrine system. The lethal effects of septic shock are associated with the production and release of numerous pro-inflammatory(More)
Previous studies have shown that melatonin acts through specific receptors, including MT(1) and MT(2) membrane receptors as well as a nuclear receptor belonging to the orphan nuclear receptor family. Therefore, the goal of this study was to determine whether melatonin receptors mRNA is expressed in mouse peripheral tissues. To study the different receptors(More)
The OPG/RANKL/RANK system is important in the balance between bone formation and resorption. We used primary human osteoblasts (hOBs) cells to examine the impact of 17-beta-estradiol (E2) or/and 1,25-dihydroxyvitamin D (1,25D) in OPG/RANKL system in 28 post-menopausal (PM) women; (a) with hip fracture (OP) or (b) with osteoarthritis (OA). The hOB from OP(More)
Mast cells take part of armamentarium immunologic for host defense against parasitic and bacterial infections. They are derived from bone marrow progenitors and can be activated by immunological and chemical stimuli in order to get its degranulation. The activation of mast cells generates a signalling cascade leaded to the rapid release of vasoactives and(More)
BACKGROUND Food allergy, in particular peanut allergy, is a growing concern in Western countries. The prevalence of allergy to peanut, which currently stands at 1.4%, nearly tripled between 1997 and 2008. Allergic sensitization is a particularly difficult process to study as it is clinically silent. We sought to identify key pathways and mediators(More)
A comparison has been made of the abilities of bone marrow cells and lymph node cells to induce tolerance of skin when inoculated into neonatal rats known to differ only with regard to non-MHC incompatibilities, including putative skin-specific (Skn) antigens. Each recipient received 50 x 10(6) cells, and tolerance was confirmed by the permanent acceptance(More)
