Lipopolysaccharides can have substantial impacts on human health, primarily through interactions with the immune system. LPS is a potent activator of the immune system and is a pyrogen (agent that causes fever). [4] In severe cases, LPS can trigger a brisk host response and multiple types of acute organ failure [5] which can lead to septic ...
Lipopolysaccharide binding protein (LBP) is a protein that in humans is encoded by the LBP gene. [5] [6]LBP is a soluble acute-phase protein that binds to bacterial lipopolysaccharide (or LPS) to elicit immune responses by presenting the LPS to important cell surface pattern recognition receptors called CD14 and TLR4.
Part of the bacterial order Bacteroidales present in the human gut, Parabacteroides are commonly found within the gut microenvironment. Parabacteroides species constitute a significant component of microbiota along the digestive tract , benefitting from a commensal relationship with the human body.
Human microbiota are microorganisms (bacteria, viruses, fungi and archaea) found in a specific environment. They can be found in the stomach, intestines, skin, genitals and other parts of the body. [1] Various body parts have diverse microorganisms. Some microbes are specific to certain body parts and others are associated with many microbiomes.
CD14 (cluster of differentiation 14) is a human protein made mostly by macrophages as part of the innate immune system. [ 5 ] [ 6 ] It helps to detect bacteria in the body by binding lipopolysaccharide (LPS), a pathogen-associated molecular pattern (PAMP).
Bacteroides thetaiotaomicron is a common bacterium in the human gut microbiome that has evolved alongside humans to support digestion and general health. Over time, this bacterium developed the ability to break down complex carbohydrates into simple sugars, which helps the host species get more energy from the food it eats.
Chemical structure of lipid A as found in E. coli [1]. Lipid A is a lipid component of an endotoxin held responsible for the toxicity of gram-negative bacteria.It is the innermost of the three regions of the lipopolysaccharide (LPS), also called endotoxin molecule, and its hydrophobic nature allows it to anchor the LPS to the outer membrane.

Lipopolysaccharide, or LPS, is the major pathogenic factor on the cell wall of Gram-negative bacteria. Gram-positive bacteria has a similar component named Lipoteichoic acid, or LTA. HDL has the ability to bind LPS and LTA, creating HDL-LPS complexes to neutralize the harmful effects in the body and clear the LPS from the body. [9]
