Contribution of receptors to 'Neisseria meningitidis' interactions with human macrophages [PDF]

open access: yes, 2004
N. meningitidis is a gram-negative human pathogen that invades human cells, evades immune responses and goes on to cause meningococcal disease, sepsis and death.

Synthetic Toll-Like Receptors for Control of Innate Immunity With Far-Red Light. [PDF]

open access: yesAdv Sci (Weinh)
Synthetic Toll‐like receptors (TLRs) are engineered by replacing their natural sensing regions with a far‐red‐light‐responsive module from a bacterial phytochrome. These synthetic receptors enable light‐controlled regulation of immune signaling in mammalian cells.

Genes, Receptors, Signals and Responses to Lipopolysaccharide Endotoxin [PDF]

open access: yesScandinavian Journal of Immunology, 2000
C3H/HeJ inbred mice have been very useful for identifying genetic elements responsible for endotoxin‐mediated responses. Depending on the type of assays employed, Tlr‐2, Tlr‐4 and Lps/Ran have been shown to be important in lipopolysaccharide (LPS)‐mediated responses. The concept of a single LPS gene being responsible for the genetic defect found in C3H/

Lipopolysaccharide Inhibits the Channel Activity of the P2X7 Receptor [PDF]

open access: yesMediators of Inflammation, 2011
The purinergic P2X7 receptor (P2X7R) plays an important role during the immune response, participating in several events such as cytokine release, apoptosis, and necrosis. The bacterial endotoxin lipopolysaccharide (LPS) is one of the strongest stimuli of the immune response, and it has been shown that P2X7R activation can modulate LPS-induced ...

Survey of innate immune responses to Burkholderia pseudomallei in human blood identifies a central role for lipopolysaccharide.

open access: yesPLoS ONE, 2013
B. pseudomallei is a gram-negative bacterium that causes the tropical infection melioidosis. In northeast Thailand, mortality from melioidosis approaches 40%.

Macrophages exposed continuously to lipopolysaccharide and other agonists that act via toll-like receptors exhibit a sustained and additive activation state [PDF]

open access: yes, 2001
Background: Macrophages sense microorganisms through activation of members of the Toll-like receptor family, which initiate signals linked to transcription of many inflammation associated genes.

Heat shock inhibits lipopolysaccharide-induced tissue factor activity in human whole blood [PDF]

open access: yes, 2007
Background During gram-negative sepsis, lipopolysaccharide (LPS) induces tissue factor expression on monocytes. The resulting disseminated intravascular coagulation leads to tissue ischemia and worsens the prognosis of septic patients.

Modulation of Toll-like receptor activity by leukocyte Ig-like receptors and their effects during bacterial infection. [PDF]

open access: yes, 2010
Toll-like receptors (TLRs) are a potent trigger for inflammatory immune responses. Without tight regulation their activation could lead to pathology, so it is imperative to extend our understanding of the regulatory mechanisms that govern TLR expression ...

Microglia activated by microbial neuraminidase contributes to ependymal cell death

open access: yesFluids and Barriers of the CNS, 2021
The administration of microbial neuraminidase into the brain ventricular cavities of rodents represents a model of acute aseptic neuroinflammation. Ependymal cell death and hydrocephalus are unique features of this model.

L-selectin — a signalling receptor for lipopolysaccharide

open access: yesChemistry & Biology, 1997
The activation of leukocytes by bacterial cell-wall lipopolysaccharide contributes to the pathogenesis of septic shock. We propose that in neutrophils, and possibly other leukocytes, L-selectin can act as a low-affinity lipopolysaccharide receptor.
