Metabolic activation of phenol by human myeloperoxidase and horseradish peroxidase.
The oxidation of phenol catalyzed by human myeloperoxidase and horseradish peroxidase resulted in extensive binding of phenol-derived metabolites to boiled rat liver protein. This binding paralleled closely the removal of phenol from the incubations and was inhibited from 83 to 99% by the addition of the antioxidants, ascorbate and glutathione, suggesting that metabolism and binding were occurr...
متن کاملActivation of Ca2+-dependent signaling by TLR2.
Upon contact with airway epithelial cells, bacterial products activate Ca(2+) fluxes that are required for induction of NF-kappaB-dependent gene expression. TLR2 is apically displayed on airway cells, making it a likely transducer linking bacterial stimuli and kinases that affect Ca(2+) release. Using biochemical and genetic approaches, we demonstrate that TLR2 ligands stimulate release of Ca(2...
متن کاملMyeloperoxidase mediates neutrophil activation by association with CD11b/CD18 integrins.
Recruitment and activation of polymorphonuclear neutrophils (PMNs) reflects a primary immunological response to invading pathogens and has also emerged as a hallmark of vascular inflammation. One of the principal enzymes released upon PMN activation is myeloperoxidase (MPO), a heme protein that not only generates cytotoxic oxidants but also impacts deleteriously on nitric oxide-dependent signal...
متن کاملCa2+/Calmodulin Modulates TRPV1 Activation by Capsaicin
TRPV1 ion channels mediate the response to painful heat, extracellular acidosis, and capsaicin, the pungent extract from plants in the Capsicum family (hot chili peppers) (Szallasi, A., and P.M. Blumberg. 1999. Pharmacol. Rev. 51:159-212; Caterina, M.J., and D. Julius. 2001. Annu. Rev. Neurosci. 24:487-517). The convergence of these stimuli on TRPV1 channels expressed in peripheral sensory nerv...
متن کاملThe effect of stress and glucocorticoids on modulation of pain in mice: Interaction with activation of voltage dependent Ca2+ channel
Previous studies indicated that stress and glucocorticoids have modulatory effects on acute pain. The aim of present study was to determine the interaction between stress and glucocorticoids with activation of voltage dependent Ca2+ channel on modulation of acute pain in mice. Male albino mice (25-30 g) were used for this experiment. Tail flick and hot plate were used for evaluation of analgesi...
