TLDR
The identification of this pathway for LPS-induced monocyte stimulation may aid in the development of treatments for diseases in which Gram-negative sepsis or endotoxemia are involved.Abstract:
The primary structure of lipopolysaccharide binding protein (LBP), a trace plasma protein that binds to the lipid A moiety of bacterial lipopolysaccharides (LPSs), was deduced by sequencing cloned complementary DNA. LBP shares sequence identity with another LPS binding protein found in granulocytes, bactericidal/permeability-increasing protein, and with cholesterol ester transport protein of the plasma. LBP may control the response to LPS under physiologic conditions by forming high-affinity complexes with LPS that bind to monocytes and macrophages, which then secrete tumor necrosis factor. The identification of this pathway for LPS-induced monocyte stimulation may aid in the development of treatments for diseases in which Gram-negative sepsis or endotoxemia are involved.read more

TL;DR: The mammalian Tlr4 protein has been adapted primarily to subserve the recognition of LPS and presumably transduces the LPS signal across the plasma membrane.

CD14, a receptor for complexes of lipopolysaccharide (LPS) and LPS binding protein.
TL;DR: CD14, a differentiation antigen of monocytes, was found to bind complexes of LPS and LBP, and blockade of CD14 with monoclonal antibodies prevented synthesis of TNF-alpha by whole blood incubated with LPS.

Toll-like receptors in the induction of the innate immune response
Alan Aderem,Richard J. Ulevitch +1 more
TL;DR: A group of proteins that comprise the Toll or Toll-like family of receptors perform this role in vertebrate and invertebrate organisms and it is therefore not surprising that studies of the mechanism by which they act has revealed new and important insights into host defence.

LPS induction of gene expression in human monocytes
Mausumee Guha,Nigel Mackman +1 more
TL;DR: This work has elucidated how LPS is recognized by monocytes and macrophages of the innate immune system and activates a variety of transcription factors that include NF-kappaB (p50/p65) and AP-1 (c-Fos/c-Jun), which coordinate the induction of many genes encoding inflammatory mediators.

TL;DR: A procedure for eucaryotic structural gene isolation which involves the construction and screening of cloned libraries of genomic DNA is presented and Restriction mapping and hybridization studies reveal the presence of closely linked beta-globin genes.

TL;DR: Results indicate that the high level of cytotoxicity mediated by CF supernatants and monocytes on WEHI 164 clone 13 cells is due to TNF as the effector molecule.
