We showed previously and we confirm here that macrophages from three mouse strains are differentially sensitive to the inhibition of expression of key inflammatory proteins (iNOS-II, IL-1 beta) by dexamethasone, a specific glucocorticoid receptor agonist (C57BL/6>DBA/2>BALB/c). Here we show that aldosterone (a specific mineralocorticoid agonist) has no(More)
We have reported previously that PGE(2) inhibits dendritic cells (DC) functions. Because E prostanoid receptor (EPR) subtypes involved in this action are unknown, expression and functions of these receptors were examined in DC. Western blot and flow cytometry analyses showed that all EPRs were coexpressed in DC. In a dose-dependent manner,(More)
Recognition of lipopolysaccharide (LPS), the endotoxin of gram-negative bacteria, by microglia occurs through its binding to specific receptors, cluster of differentiation 14 and toll-like receptor-4. LPS binding to these receptors triggers the synthesis of proinflammatory cytokines that coordinate the brain innate immune response to protect the CNS of the(More)
Male and female mice from different control strains (C57BL/6, DBA/2, BALB/c) and the nonobese diabetic (NOD) strain, a spontaneous model of type 1 diabetes, were subjected to various stressors (restraint, lipopolysaccharide or interleukin-1 injection). Significant differences were measured among strains in blood glucose, insulin and corticosterone levels(More)
There is considerable evidence that host genetic factors are important in determining susceptibility to mycobacterial infections. More recently, functional genetic mutations affecting IL-10 receptor 1 (IL-10R1) were described. In this study, we investigated the relationship of IL-10R1 S138G loss-of-function polymorphism (A536G: rs3135932) with(More)
