The murine neonatal Fc receptor, FcRn, carries out two functions: materno-fetal IgG delivery and maintenance of serum IgG homeostasis. During human pregnancy maternal IgG is transferred across placental syncytiotrophoblasts presumably by the human homolog of FcRn, hFcRn. Trophoblast-derived BeWo cells express hFcRn endogenously and can be considered as a(More)
Neointima formation involves tissue expression of matrix proteins and growth factors. The role of alphavbeta3, but not alphavbeta5 integrin in vascular cells has been sufficiently investigated. The aim of the present study was to determine and compare the function of alphavbeta3 and alphavbeta5 integrins in rat aortic (RASMC) and human coronary vascular(More)
Systemic inflammation leads to increased expression of spinal cyclooxygenase (COX)-2 and to a subsequent increase of prostaglandin (PG) biosynthesis, which contribute to the development of hyperalgesia and allodynia. In this study, endotoxin caused a sequential induction of membrane bound prostaglandin E synthase-1 and lipocalin-type PGD synthase (L-PGDS)(More)
The human neonatal Fcgamma-receptor (hFcRn) involved in overall maternal-fetal IgG transmission is expressed in placental villous syncytiotrophoblast. However, the role of hFcRn in IgG transport and trafficking across this cell layer is poorly characterized. To gain insight into this mechanism we have overexpressed functional hFcRn in trophoblast-derived(More)
Although prostaglandin (PG)D2 is one of the main metabolites of the cyclooxygenase (COX) pathway of arachidonate metabolism in the brain, relatively little is known about the regulation of PGD2 biosynthesis in the spinal cord during systemic inflammation. Therefore, the present study was aimed at investigating the effect of endotoxin treatment on spinal(More)
CD40-CD154-mediated signaling has recently been described as playing a role in cellular functions involved in atherosclerotic processes. CD40 is expressed in macrophages, lymphocytes, endothelial cells, and vascular smooth muscle cells. However, cross-sectional studies investigating the expression of CD40 in atherosclerotic lesions are lacking. In the(More)
Enhanced biosynthesis of prostaglandin (PG)D(2) and subsequent formation of 15-deoxy-Delta(12,14)-PGJ(2) has been suggested to contribute to resolution of inflammation. The primary aim of the present study in mouse heart was, therefore, to determine at the transcriptional level if there is sequential induction of PGE and PGD synthases (S) during(More)
Interleukin-6 (IL-6) participates in the host response to injury and infection in the central nervous system (CNS). We identified strawberry notch homolog 2 (Sbno2) as an IL-6-stimulated gene in murine astrocytes. Sbno2 is a mouse homolog of the sno gene in Drosophila but little is known about the regulation or function of the mammalian gene. Here we(More)
human umbilical venous endothelial cells. 7E3 binding correlated with alphavbeta3-expression in all cell types. Integrin-mediated cell functions were analysed with adhesion and spreading assays on vitronectin. In human umbilical venous endothelial cells, these functions were mediated by alphavbeta3 and in human iliac arterial smooth muscle cells by(More)
BACKGROUND AND AIMS Prostaglandin [PG] D2 activates two receptors, DP and CRTH2. Antagonism of CRTH2 has been shown to promote anti-allergic and anti-inflammatory effects. We investigated whether CRTH2 may play a role in Crohn's disease [CD], focusing on eosinophils which are widely present in the inflamed mucosa of CD patients and express both receptors.(More)
