LPS-binding proteins and receptors.
Macrophage activation by gram-negative lipopolysaccharide (LPS) has been extensively studied in an attempt to define the mechanisms that underlie innate immunity against bacterial pathogens. Dysregulation of these same mechanisms contributes to the pathophysiological consequences of bacterial sepsis. The biological actions of LPS are mediated, at least in part, by both LPS-binding proteins and ...
متن کاملCyclic Limulus anti-lipopolysaccharide (LPS) factor-derived peptide CLP-19 antagonizes LPS function by blocking binding to LPS binding protein.
Inflammation and septic shock due to endotoxins from Gram-negative bacteria infection continue to pose significant challenges to human healthcare. It is, therefore, necessary to develop therapeutic strategies targeting endotoxins, such as lipopolysaccharide (LPS), to prevent their potentially systemic effects. Pathogenesis due to Gram-negative bacteria involves LPS binding to the host LPS-bindi...
متن کاملDifferential regulation of lipopolysaccharide (LPS) activation pathways in mouse macrophages by LPS-binding proteins.
LPS binding to its receptor(s) on macrophages induces the synthesis of inflammatory mediators involved in septic shock. While the signaling mechanism(s) remains to be fully defined, the human LPS-binding protein (LBP) is known to regulate responses to LPS by facilitating its binding to CD14 on human monocytes. The structurally related bactericidal permeability increasing protein (BPI) differs f...
متن کاملAssociation between protective efficacy of anti-lipopolysaccharide (LPS) antibodies and suppression of LPS-induced tumor necrosis factor alpha and interleukin 6. Comparison of O side chain-specific antibodies with core LPS antibodies
Two-core LPS antibodies, the rabbit J5 polyclonal antiserum and the human anti-lipid A IgM mAb HA-1A, did not improve the survival of mice challenged with E. coli O111 or P. aeruginosa 3, or with the LPS extracted from them, and did not decrease the incidence of Shwartzman reactions in rabbits challenged with O111 LPS. In contrast, O side chain-specific rabbit antisera were protective in these ...
