Abstract Innate immune receptors recognize microorganism-specific motifs. One such receptor-ligand complex is formed between the mammalian Toll-like receptor 4 (TLR4)-MD2-CD14 complex and bacterial lipopolysaccharide (LPS). Recent research indicates that there is significant phylogenetic and individual diversity in TLR4-mediated responses. In addition, the diversity of LPS structures and the differential recognition of these structures by TLR4 have been associated with several bacterial diseases. This review will examine the hypothesis that the variability of bacterial ligands such as LPS and their innate immune receptors is an important factor in determining the outcome of infectious disease.
