Structurally, they are composed of three parts: O-antigen, core oligosaccharide, and Lipid A, and can be identified by the monoclonal antibody MAb J8-4C10. This compound can increase pro-inflammatory cytokines in plasma, leading to activation of the hypothalamic-pituitary-adrenal (HPA) axis and causing oxidative damage to the adrenal glands. However, the pathogenic activity of Lipopolysaccharides from *E. coli* O26:B6 can be inhibited by PD149163 (HY-123434).

Lipopolysaccharides from E. coli O127:B8 (LPS, from Escherichia coli (O127:B8)) are endotoxins and TLR-4 activators extracted from the bacterium E. coli O127:B8. This smooth (S) type LPS features a typical tripartite structure: an O antigen, an R3 core oligosaccharide, and lipid A. When lipopolysaccharides from E. coli O127:B8 activate TLR-4 on immune cells, they can trigger inflammatory responses and ileal contractility, making them useful for developing intestinal inflammation models.

Lipopolysaccharides, from E. coli O128:B12 (LPS, from Escherichia coli [O128:B12]) are lipid polysaccharide endotoxins and TLR-4 activators derived from E. coli O128:B12, characterized as a smooth (S) type LPS. This compound features a typical three-part structure: O antigen, R3 core oligosaccharide, and lipid A. It activates TLR-4 in immune cells, is useful for developing neonatal brain inflammation models in animals, and may impact preterm birth in neonates.

Lipopolysaccharides, from E. coli (Escherichia coli) K-235, are endotoxins derived from Escherichia coli and serve as TLR-4 activators. They are an S-type LPS capable of activating pathogen-associated molecular patterns (PAMP) of the immune system and inducing the secretion of exosomes. This compound is characterized by a typical three-part structure comprising the O-antigen, core oligosaccharide, and Lipid A. Additionally, lipopolysaccharides from E. coli K-235 stimulate mitogenesis in C57BL 10ScN spleen cells and, when purified by butanol and deoxycholate methods, can stimulate spleen cells from C57BL 10ScCR and C3H HeJ mice.
