To examine the molecular interaction among lipopolysaccharide-binding protein (LBP), chylomicrons, and bacterial endotoxin in neutralizing bacterial toxicity.
Assessed the kinetics and binding capacity of LBP and lipopolysaccharide (LPS) to chylomicrons across varying doses.
Quantified inflammatory cytokine secretion from peripheral blood mononuclear cells (PBMC) exposed to LPS in the presence of LBP-chylomicron complexes.
Compared LPS-inactivating capacities of postprandial chylomicrons against LDL, VLDL, and HDL, and evaluated detoxification of Gram-positive lipoteichoic acid.
LBP associated directly with chylomicrons, accelerating dose-dependent LPS binding and substantially reducing endotoxin-induced cytokine secretion in PBMC.
At physiological postprandial concentrations, chylomicrons exhibited greater LPS-inactivating capacity than low-density, very-low-density, and high-density lipoproteins.
Incubation with LBP and chylomicrons effectively detoxified lipoteichoic acid derived from Gram-positive bacteria.
