Lipopolysaccharides, from E. coli O111:B4

Lipopolysaccharides are lipopolysaccharide endotoxins and TLR-4 activators that activate pathogenicity-associated molecular patterns (PAMPs) of the immune system and induce cell secretion of migrasomes. Lipopolysaccharides can be extracted from the outer leaflet of the outer membrane of Gram-negative bacteria and are composed of an antigenic O-specific chain, a core oligosaccharide, and lipid A. Lipopolysaccharides, from E. coli O111:B4 is a kind of endotoxins derived from E. coli[1][2][3][4][1].
