Heterogeneity of Rhizobium lipopolysaccharides [PDF]

Journal of Bacteriology, 1984
The lipopolysaccharides ( LPSs ) from strains of Rhizobium leguminosarum, Rhizobium trifolii, and Rhizobium phaseoli were isolated and partially characterized by mild acid hydrolysis and by polyacrylamide gel electrophoresis. Mild acid hydrolysis results in a precipitate which can be removed by centrifugation or extraction with chloroform.

Lipopolysaccharide Binding Protein-mediated Complexation of Lipopolysaccharide with Soluble CD14 [PDF]

Journal of Biological Chemistry, 1995
Endotoxin (lipopolysaccharide; LPS) activates a wide variety of host defense mechanisms. In mammals LPS binding protein (LBP) and CD14 interact with LPS to mediate cellular activation. Using sucrose density gradients and a fluorescent endotoxin derivative we have investigated the mechanism of LPS binding to LBP and the soluble form of CD14 (sCD14). LPS

Dual‐Nanoparticle Engineered Hydrogel Reverses Bicellular Oxidative Stress to Accelerate Diabetic Fracture Healing

Advanced Functional Materials, EarlyView.
CD105‐LNPs and PS‐LNPs can deliver α‐lipoic acid to bone marrow mesenchymal stem cells and bone marrow‐derived macrophages, reversing high glucose‐induced oxidative stress while enhancing osteogenesis and M2 polarization. Integrating both nanoparticles into glucose‐responsive hyaluronic acid hydrogel forms DLNPs@HA hydrogel, which accelerates diabetic ...

Immune cell profile and metabolic preference following intramuscular lipopolysaccharide injection of highly inbred and advanced intercross genetic lines

Frontiers in Veterinary Science
Lipopolysaccharide (LPS), a gram-negative bacterial cell wall component commonly used in animal models of inflammation, is also universally found in poultry environments. Documented LPS effects in production animals include reduced feed intake and weight

Distribution of endotoxin (lipopolysaccharide) in the tissues of lipopolysaccharide-responsive and -unresponsive mice [PDF]

Infection and Immunity, 1978
We examined the distribution of bacterial lipopolysaccharide (LPS) in LPS-responsive (C3H/St) and LPS-unresponsive (C3H/HeJ) mice. The results reported here demonstrate that the rates of removal of an immunological or a toxic dose of LPS from the circulation are the same in both strains of mice.

Immunological and Physiological Differences Between Layer- and Broiler Chickens after Concurrent Intratracheal Administration of Lipopolysaccharide and Human Serum Albumin [PDF]

, 2010
Layers and broilers were concurrently intratracheally challenged with 0.5 mg Lipopolysaccharide (LPS) and 0.1 mg Human Serum Albumin (HuSA) at 3 weeks of age.

The aggregation of Brucella abortus occurs under microaerobic conditions and promotes desiccation tolerance and biofilm formation [PDF]

, 2012
Brucella abortus causes brucellosis mainly in cattle. The infection is transmitted to humans by ingestion of animal products or direct contact with infected material.

Recognition of lipopolysaccharide pattern by TLR4 complexes

Experimental and Molecular Medicine, 2013
Lipopolysaccharide (LPS) is a major component of the outer membrane of Gram-negative bacteria. Minute amounts of LPS released from infecting pathogens can initiate potent innate immune responses that prime the immune system against further infection ...

Biomaterial Strategies for Targeted Intracellular Delivery to Phagocytes

Advanced Functional Materials, EarlyView.
Phagocytes are essential to a functional immune system, and their behavior defines disease outcomes. Engineered particles offer a strategic opportunity to target phagocytes, harnessing inflammatory modulation in disease. By tuning features like size, shape, and surface, these systems can modulate immune responses and improve targeted treatment for a ...
