Biophysical chemistry of lipopolysaccharide specific bacteriophages
… of O antigen in its host´s outer membrane lipopolysaccharide molecule. This is mediated by tailspikes, mainly β helical appendages on phage P22 short non contractile tail apparatus (podovirus). The O antigen of all three Salmonella enterica hosts is built from tetrasaccharide repeating …

Antibody Response to Lipopolysaccharide of Salmonella Typhimurium
This differential mAb recognition of O-Ag had a direct correlation with the differential level of protection mediated by individual mAbs in mice challenged with virulent S. typhimurium. Therefore, a subtle modification of O-Ag such as acetylation has a profound effect on the host immune response.

Antioxidants Facilitate Recovery From Lipopolysaccharide Induced Sickness
Collectively, these data suggest that alpha-T and selenium do not prevent SB but promote recovery from LPS-induced sickness in adult and aged mice. This is particularly important given that the elderly population often experience marginal nutrient deficiencies, are immunocompromised and highly …

Behavioral and Physiological Responses to Lipopolysaccharide in the Chicken
… this concept to birds by demonstrating that lipopolysaccharide (LPS) injected intraperitoneally (i.p.) increases body temperature (T$\sb{\rm b}$), reduces feed intake, increases somnolence, decreases plasma (Fe) and (Zn), increases plasma (Cu), and elevates plasma corticosterone. To determine …

Pronthocyanidin-Rich Cranberry-FractionInduced Alteration of Periodontal Pathogen Lipopolysaccharide Functions
<p>The cranberry (species: Vaccinium macrocarpon, family: Ericaceae) is a polyphenolicrich berry fruit native to North America and exhibits numerous beneficial properties for human health, such as inhibition of human cancer cell line proliferation and prevention of urinary tract colonization by …

Elucidating Human Inflammasome Responses To Legionella Pneumophila And Lipopolysaccharide Variants
… order to release pathogen-derived products, such lipopolysaccharide (LPS), into the cytosol for downstream host sensing and inflammasome activation. In contrast to mice, which possess 11 GBPs, humans have 7 GBPs and their role in inflammasome activation in human macrophages is poorly understood. …

Effects of β-funaltrexamine on lipopolysaccharide-induced inflammation and behavior
Inflammation plays a crucial role in the development, progression, and severity of many prevalent systemic and neurological pathologies. A growing body of evidence has found that inflammation is a key aspect of cardiovascular disease, autoimmune disorders, cancer, neurodegenerative diseases, and …

LECTINS FROM THE HORSESHOE CRAB, LIMULUS POLYPHEMUS, REACTIVE WITH BACTERIAL LIPOPOLYSACCHARIDE
… of precipitating various components of the lipopolysaccharide molecule from R mutants of Salmonella minnesota. Precipitation-inhibition studies using 2-keto-3-deoxyoctonate (KDO) have supported the hypothesis that this acidic residue is the immunodeterminant group in the core region of the …

The interaction of antimicrobial peptides with lipopolysaccharide aggregates and model membranes.
Lipopolysaccharides (LPS) released from the outer membrane (OM) of Gram negative bacteria form aggregates which trigger an in ammatory response in humans and can result in severe septic shock. LPS molecules are heterogenic, macroamphiphilic oligosaccharides with a pro-in ammatory activity strictly …

Molecular Mechanisms Governing Persistent Induction of Pro-Inflammatory Genes by Lipopolysaccharide
… lipocalin 2 (LCN2) in response to 100 ng/mL of lipopolysaccharide (LPS) in kidney fibroblasts was examined. It appears that the intracellular signaling network responsible for the persistent induction of LCN2 requires both activator protein-1 (AP-1) and CCAAT/enhancer binding protein delta …

Effects of Lipopolysaccharide Induced Inflammatory Response on Early Embryo Survival in Ewes
… a gram-negative bacteria cell wall component, lipopolysaccharide (LPS) or tumor necrosis factor-alpha (TNF-&agr;), to induce an innate immune system acute phase response (APR). The induction of the APR and its reactant molecules, such as TNF-&agr; and acute phase proteins (APP), haptoglobin …

Characterization and differentiation of a soluble lipopolysaccharide type antigen from Treponema hyodysenteriae.
… chemically extracted to selectively remove a lipopolysaccharide-like substance (LPSLS). The different LPSLS were analyzed electrophoretically, immunologically, and chemically. SDS-PAGE demonstrated migratory differences that were unique for individual serotypes/strains. Additional differences …

Immunoprotective effects of lipopolysaccharide detoxification by a novel microbial-derived alkaline phosphatase
Lipopolysaccharide (LPS) is a major outer cell wall component of Gram-negative bacteria, including Escherichia coli and Salmonella enterica, which have important health and economic consequences in animal agriculture. LPS is a recognized endotoxin that stimulates toll-like receptors, which are …

Identification of Acyloxyacyl Hydrolase, a Lipopolysaccharide Detoxifying Enzyme, in the Murine Urinary Tract
… the bioactive center of Gram-negative bacterial lipopolysaccharides (LPS). Such limited deacylation has been shown to attenuate cytokine and chemokine responses to LPS, suggesting a role for AOAH in modulating (downregulating) inflammatory responses to invading Gramnegative bacteria. Prior to the …
