LPS-binding protein (LBP) recognizes bacterial LPS and transfers it to CD14, thereby enhancing host cell stimulation, eventually resulting in pathogenic states such as septic shock. Recently, LBP also was shown to detoxify LPS by transferring LPS into HDL particles in vitro. Thus, the predominant in vivo function of LBP has remained unclear. To investigate(More)
LPS-binding protein (LBP) is a 60-kDa acute phase glycoprotein capable of binding the LPS of Gram-negative bacteria and facilitating its diffusion. This process is thought to be of potential importance in inflammatory reactions and pathogenic states such as septic shock syndrome. Here, we report on the identification of a LPS binding domain within the LBP(More)
It was the aim of this study to compare drug-resistant sublines of the murine P388 in relation to resistance markers, the resistant phenotype and immunogenicity. Resistance to drugs either belonging to the MDR type (Doxorubicin, Vincristine, Mitoxantrone) or to the non-MDR type (Methotrexate) was generated in vivo in order to mimic the clinical situation.(More)
We have cloned by homology screening from a rat brain cDNA library a GIRK3-type (Kir 3.3) inwardly rectifying K+ channel subunit with high structural similarity to other subfamily members whose activity is thought to be controlled by receptor-stimulated G proteins. When heterologously expressed both in Xenopus oocytes and in mammalian COS-7 cells, rbGIRK3(More)
Cell wall compounds of gram-positive bacteria are capable of inducing the biosynthesis of proinflammatory cytokines in CNS cells in a similar way as lipopolysaccharide (LPS) of gram-negative bacteria does. Astrocytes, which lack the CD14 LPS receptor, have also been shown to respond to LPS-stimulation by increased cytokine synthesis. However, almost nothing(More)
The transfer of lipids in aqueous environments such as serum has been attributed to a recently characterized class of proteins. Abnormal regulation of serum lipids by these proteins is thought to be a key event in the pathophysiology of cardiovascular diseases. Lipopolysaccharide (endotoxin) binding protein (LBP) was identified by virtue of its ability to(More)
Human vascular endothelial cells (HUVECs), which do not display the lipopolysaccharide (LPS) receptor CD14, were examined for protein tyrosine phosphorylation after LPS stimulation in the presence and absence of soluble CD14 (sCD14). By phosphotyrosine Western blotting and immunocomplex kinase assays we show that LPS was capable of inducing in these cells(More)
We have shown previously that phenol/water extracts derived from two novel Treponema species, Treponema maltophilum, and Treponema brennaborense, resembling lipoteichoic acid (LTA), induce cytokines in mononuclear cells. This response was lipopolysaccharide binding-protein (LBP)-dependent and involved Toll-like receptors (TLRs). Here we show that secretion(More)
Lipopolysaccharide (LPS) Binding Protein (LBP) is an acute phase protein with the ability to recognize bacterial LPS and transport it to the CD14 molecule or into HDL particles. It is synthesized in hepatocytes and secreted into the blood stream. LBP levels significantly rise during the acute phase response and levels of LBP may be important for an(More)
Newborn screening (NBS) protocols for cystic fibrosis (CF) are the first regional population-based programs to incorporate DNA analysis into their procedures. Research about these programs can inform policy and practice regarding how best to counsel families with abnormal NBS results. The grounded theory method guided interviews with 33 families whose(More)
