Lipopolysaccharides, from S. enterica serotype typhimurium

LPS, from Salmonella enterica (Serotype typhimurium)

Carbohydrates

Lipopolysaccharides, from S. enterica serotype typhimurium, are a kind of lipid-polysaccharide endotoxin. Smooth Gram-negative bacteria's lipopolysaccharides are made up of three components: lipid A, core oligosaccharide, and O antigen (OAg). The O antigen is a polymer of sugar repeat units (RUs); the Wzz protein regulates the length of the O antigen in lipopolysaccharides, and the number of RUs attached to lipid A is determined by the modal value set by the Wzz protein. S. enterica typhimurium has two Wzz proteins: Wzz_ST (which makes the modal range of the O antigen between 16 and 35 RUs) and Wzz_fepE (which makes the modal value over 100 RUs). Mutating the genes corresponding to these two proteins causes the formation of short-chain O antigen chains and significantly reduces bacterial pathogenicity .

Lipopolysaccharides, from S. enterica serotype minnesota

LPS, from Salmonella enterica (Serotype minnesota)

Carbohydrates

Lipopolysaccharides (LPS) are specific endotoxins and one of the major components of the cell wall of Gram-negative bacteria. Lipopolysaccharides consist of three parts: lipid A, core oligosaccharide, and O-specific polysaccharide. Lipopolysaccharides are powerful immune stimulants that can activate the host immune system, particularly by binding to Toll-like receptor 4 (TLR4) on the surface of immune cells, triggering an inflammatory response. The LPS of most Salmonella serotypes has a complex O-antigen (OAg) structure, with the number of OAg units in the core polysaccharide varying between 16 and over 100 repeats. Mutations in OAg-regulating factors that alter the OAg structure can change the interaction between Salmonella and epithelial cells. Strains with long OAg have increased SPI1-T3SS effector protein translocation and invasion. Strains completely lacking OAg exhibit increased invasiveness and higher adhesiveness. This product is derived from Salmonella enterica serotype Minnesota. Lipopolysaccharides, from S. enterica serotype minnesota, can be used to study host immune system activation and its role in inflammation and immune regulation .
