Isolation of lipopolysaccharide endotoxin.
Endotoxins, generally produced by gram-negative bacteria, are responsible for harmful effects in many diseases. These toxic compounds of nonprotein nature are part of the intact bacterial cells as opposed to the protein exotoxins found in cell-free broth cultures. Reviews concerning endotoxins have been published by Burrows (l), and by Westphal et al. (2). This report deals with the isolation, ...
متن کاملOptimized Mouse BMDC Isolation and Culture under Endotoxin-Free Conditions
Introduction: Dendritic cells are very important in basic studies and vaccine research, but isolation and culture of these cells face challenges due to their small number in tissues. Since there is no standard method, we addressed some of the factors affecting the efficiency of dendritic cell isolation and culture from BALB/c mouse bone marrow. Materials & Methods: Bone marrow cells isolated...
متن کاملLipopolysaccharide detoxification by endotoxin neutralizing protein.
Endotoxin neutralizing protein (ENP), a recombinant form of the anti-lipopolysaccharide factor that was isolated from amebocytes of the American horseshoe crab, Limulus polyphemus, detoxifies lipopolysaccharide (LPS) both in vitro and in vivo. Using the Limulus amebocyte lysate assay, LPS was detoxified by ENP at a 1 to 1 weight ratio (1:1). When isolated rat aortic rings were preincubated for ...
متن کاملLipopolysaccharide: an endotoxin or an exogenous hormone?
Conventional models of the pathogenesis of sepsis assume that microorganisms or their products are necessarily injurious to the host. In contrast, an evolutionary perspective suggests that host-microbial interactions are a symbiotic model and that disease results from the disruption of a mutually beneficial homeostatic state. Lipopolysaccharide (LPS) from gram-negative bacteria is a prototypica...
متن کاملEndotoxin interactions with lipopolysaccharide-responsive cells.
Recent work has identified two proteins that work together to enable many cell types to respond to endotoxin. These two proteins, lipopolysaccharide (LPS) binding protein (LBP) and CD14, also participate in cellular internalization of endotoxin, which may occur independently of cellular activation. Current work with antibodies to LBP and CD14 as well as "knockout" mice in the context of LPS-ini...
