The lipopolysaccharides (LPS) are ubiquitous components of the outer leaflet of the outer membrane of all gram-negative bacteria and are the principal toxic products of these organisms (1). The membrane anchor of LPS is lipid A, a central phosphodisaccharide unit that is attached to multiple [beta]-hydroxy fatty acid chains. LPS also contains the novel sugar, 3-deoxy-D- mannooctulosonic acid (KDO). Although generally believed to be restricted to prokaryotes, specifically the gram-n...

Response of the blood cell of the american horseshoe crab, limulus polyphemus, to a lipopolysaccharide-like molecule from the green alga chlorella.(Brief Article)
The Biological Bulletin ; R. L. Pardy (1) The granular amebocyte is the single cell type in the general circulation of the horseshoe crab, Limulus polyphemus, and functions as the most important element in the immune system of the animal. The cytoplasm of the cell is packed with granules containing multiple immune effector
Gram-negative bacterial LPS induced poor uterine receptivity and implantation failure in mouse: Alterations in IL-1[beta] expression in the preimplantation embryo and uterine horns
Infectious Diseases in Obstetrics and Gynecology ; Abstract Genito-urinary tract or systemic infections of the gram-negative bacteria in pregnant women, causes abortions, preterm labor, and several other perinatal complications. LPS is the most potent antigenic component of the gram-negative bacterial cell wall and is known to modulate the
Effect of Bacterial Endotoxins on Superovulated Mouse Embryos In Vivo: Is CSF-1 Involved in Endotoxin-Induced Pregnancy Loss?
Infectious Diseases in Obstetrics and Gynecology ; Mammalian embryonic development is regulated by several cytokines and growth factors from embryonic or maternal origins. Since CSF-1 plays important role in embryonic development and implantation, we investigated its role in gram-negative bacterial LPS-induced implantation failure. The effect of
Norepinephrine Is a More Potent Inhibitor of Tumor Necrosis Factor Over a Range of Doses Than Dopamine
The American Surgeon ; In the current study, we test the hypothesis that norepinephrine has greater anti-inflammatory effects versus dopamine over a range of doses in a model of lipopolysaccharide (LPS)-stimulated cytokine release in human saphenous vein. Segments of saphenous vein were cut and separated into 1 mm 1 mm

HIV Impairs TNF-[alpha] Release in Response to Toll-Like Receptor 4 Stimulation in Human Macrophages In Vitro
American Journal of Respiratory Cell and Molecular Biology ; The molecular mechanisms for increased risk of bacterial pneumonia in HIV+ persons remain incompletely understood. Recognizing the critical role of Toll-like receptor (TLR) signaling in host defense, this study showed that human U937 macrophage stimulation by the TLR4-specific ligand, lipid A
Cytoskeletal organization of Limulus amebocytes pre- and post-activation: comparative aspects.
The Biological Bulletin ; Introduction Only a single cell type--the granular amebocyte--is believed to circulate in the hemolymph (blood) of Limulus polyphemus, the American horseshoe crab. However, the amebocyte is multifunctional with respect to innate immune mechanisms, playing a role in phagocytosis, wound healing, and
Dandelion (Taraxacum officinale) flower extract suppresses both reactive oxygen species and nitric oxide and prevents lipid oxidation in vitro.
Phytomedicine: International Journal of Phytotherapy & Phytopharmacology ; Abstract Flavonoids and coumaric acid derivatives were identified from dandelion flower (Taraxacum officinale). Characteristics of chain-breaking antioxidants, such as extended lag phase and reduced propagation rate, were observed in oxidation of linoleic acid emulsion with the addition of
