Intercellular Transfer by Phage Receptor Site Lipopolysaccharide

Nature New Biology, 1972
TREATMENT of Escherichia coli cells with lysozyme and EDTA partially removes the outer layer of the cell wall containing lipopolysaccharide (LPS), leaving osmotically unstable spheroplasts1. These can be infected with phage nucleic acid2 and can produce viable phage particles.

Lipopolysaccharide is the receptor for kappa phage inSerratia marcescens

Antonie van Leeuwenhoek, 1991
Kappa phage active on Serratia marcescens can form plaques on white and red strains with identical efficiencies. To identify the kappa phage receptor, the inactivation of the phage was studied after incubation with several bacterial subcellular fractions.

Lipopolysaccharide and TNFα regulate the expression of GDNF, neurturin and their receptors

NeuroReport, 2003
Inflammatory processes in the brain may trigger specific neuroprotective responses in glial cells. Here, we show that bacterial lipopolysaccharide strongly up-regulates glial derived neurotrophic factor (GDNF) mRNA while it down-regulates that of neurturin.

Lipopolysaccharide-induced apoptosis of olfactory receptor neurons in rats

Acta Oto-Laryngologica, 2007

Lipopolysaccharide Decreases Scavenger Receptor mRNA In Vivo

Journal of Interferon & Cytokine Research, 1997
Lipopolysaccharide (LPS) downregulates scavenger receptor (ScR) activity in cultured macrophages through release of tumor necrosis factor-alpha (TNF-alpha). However, LPS administration in vivo stimulates cytokine release from both macrophages and lymphocytes, the combined effects of which could alter ScR expression differently from TNF-alpha in ...

Regulation of Intracellular Polymorphonuclear Leukocyte Fc Receptors by Lipopolysaccharide

Cellular Immunology, 1994
Endotoxemia, in man, has been associated with an autooxidative reduction in the bioavailability of polymorphonuclear leukocyte receptors. The location and mechanisms of this phenomena have remained unclear; we investigated the effects of lipopolysaccharide (LPS) on intracellular Fc gamma receptor expression.

Pronase destroys the lipopolysaccharide receptor CD14 on Kupffer cells

American Journal of Physiology-Gastrointestinal and Liver Physiology, 1999
CD14 is a lipopolysaccharide (LPS) receptor distributed largely in macrophages, monocytes, and neutrophils; however, the role of CD14 in activation of Kupffer cells by LPS remains controversial. The purpose of this study was to determine if different methods used to isolate Kupffer cells affect CD14.

Lipopolysaccharide-induced lung injury: Role of P2X7 receptor

Respiratory Physiology & Neurobiology, 2011
P2X7 receptors have been involved in inflammatory and immunological responses, and their activation modulates pro-inflammatory cytokines production by LPS-challenged macrophages.To determine the role of P2X7R in LPS-induced acute lung injury in mice.Wild-type (C57BL/6) and P2X7 knockout mice received intratracheal injection of saline or Escherichia ...

Functional Aspects and Nature of the Lipopolysaccharide-Receptor of Human Erythrocytes

Journal of Infectious Diseases, 1973
We have isolated for the first time from human erythrocytes a physicochemically homogeneous lipo-glycoprotein that is rich in neuraminic acid, has a molecular weight of 228,000, and prevents attachment to erythrocytes of unheated and heated, smooth and rough endotoxin of all gram-negative bacteria tested.

Inhibition of bovine gingival laminin receptor by bacterial lipopolysaccharide

Archives of Oral Biology, 1991
A laminin receptor was isolated from bovine gingival epithelial-cell membrane. After solubilization with octylglucoside, the receptor was subjected to affinity chromatography on laminin-coupled Sepharose and eluted with cation-free EDTA buffer yielding on SDS-PAGE a 67 kDa protein band. After radioiodination, the protein was incorporated into liposomes
