<p>Lipopolysaccharides are a heterogeneous group of molecules that include endotoxins, lipid A, and core oligosaccharide. They are released from the cell wall of gram-negative bacteria as a result of bacterial lysis. Lipopolysaccharides are potent activators of immune cells, inducing the secretion of pro-inflammatory cytokines such as tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β). TNF-α is also known to induce the production of other pro-inflammatory cytokines including IL-6, IL-8, IL-10, and IL-12. Lipopolysaccharides have been shown to cause liver damage in animals by increasing plasma alanine aminotransferase levels.
