Endotoxin LPS (Lipopolysaccharide) is a component of the outer membrane of Gram-negative bacteria that potently promotes the activation of macrophages and microglia cells, which are important sensors of infection by bacteria, fungi, and viruses, in both the periphery and the CNS (Central Nervous System). There are several known LBP (LPS-Binding Proteins) present on macrophage membranes, including CD14, CD11b/18, and TLR (Toll-like Receptors). TLRs are mammalian homologs of the Drosophila Toll receptor and are involved in initiat...
