Skap2 is required for defense against k. Pneumoniae infection and neutrophil respiratory burst

Klebsiella pneumoniae is a respiratory, blood, liver, and bladder pathogen of significant clinical concern. We show that the adaptor protein, SKAP2, is required for protection against K. pneumoniae (ATCC 43816) pulmonary infections. Skap2-/-mice had 100-fold higher bacterial burden when compared to wild-type and burden was controlled by SKAP2 expression in innate immune cells. Skap2-/-neutrophils and monocytes were present in infected lungs, and the neutrophils degranulated normally in response to K. pneumoniae infection in mice; however, K. pneumoniae-stimulated reactive oxygen species (ROS) production in vitro was abolished. K. pneumoniae-induced neutrophil ROS response required the activity of SFKs, Syk, Btk, PLC2, and PKCs. The loss of SKAP2 significantly hindered the K. pneumoniae-induced phosphorylation of SFKs, Syk, and Pyk2 implicating SKAP2 as proximal to their activation in pathogen-signaling pathways. In conclusion, SKAP2-dependent signaling in neutrophils is essential for K. pneumoniae-activated ROS production and for promoting bacterial clearance during infection.

The beta2 Integrin Mac-1 Induces Protective LC3-Associated Phagocytosis of Listeria monocytogenes

The intracellular pathogen Listeria monocytogenes (L.m.) is targeted by the autophagic machinery, but the molecular mechanisms involved and consequences for anti-listerial immunity remain enigmatic. Here, we demonstrate that L.m. infection of macrophages in vivo exclusively evokes LC3-associated phagocytosis (LAP), but not canonical autophagy, and that targeting of L.m. by LAP is required for anti-listerial immunity. The pathway leading to LAP induction in response to L.m. infection emanates from the beta2 integrin Mac-1 (CR3, integrin alphaMbeta2), a receptor recognizing diverse microbial ligands. Interaction of L.m. with Mac-1 induces acid sphingomyelinase-mediated changes in membrane lipid composition that facilitate assembly and activation of the phagocyte NAPDH oxidase Nox2. Nox2-derived reactive oxygen species then trigger LC3 recruitment to L.m.-containing phagosomes by LAP. By promoting fusion of L.m.-containing phagosomes with lysosomes, LAP increases exposure of L.m. to bactericidal acid hydrolases, thereby enhancing anti-listerial activity of macrophages and immunity of mice. Listeria monocytogenes are targeted by the autophagic machinery via unclear molecular mechanisms. Gluschko and Herb et al. demonstrate that LC3-associated phagocytosis, but not canonical autophagy, is required for elimination of L. monocytogenes by macrophages and activated by the beta2 integrin Mac-1 (CR3, integrin alphaMbeta2).

Chemiluminescence of phthalhydrazide derivatives in organized media: Interactions with surfactants and cyclodextrins

The chemiluminescent oxidation of some phthalhydrazide derivatives, luminol (LUM), isoluminol (ISOL), N-(4-aminobutyl)-N-ethylisoluminol (ABEI) and N-(6-aminohexyl)-N-ethylisoluminol (AHEI), has been carried out in micellar media and in the presence of natural cyclodextrins (CDs), using Co(II) as catalyst and H2O2 as oxidant. The cationic cetyltrimethylammonium bromide (CTAB) and, in a lesser extent, the anionic sodium dodecyl sulfate (SDS) produce quenching in the chemiluminescence (CL) of all the luminophores at concentrations above the cmc, whereas slight enhancements are attained with the non-ionic pentaethylene glycol monododecyl ether (C12E5). On the contrary, the incorporation of the CDs to the reaction produces a remarkable intensification of the CL. Binding of the luminophores to the macrocycles and the micelles has been studied by Pulsed-Gradient-Spin-Echo-NMR (PGSE-NMR) and fluorescence anisotropy. The cationic CTAB decreases the emission mainly due to charge compensation as a result of the association of the luminophores and the luminescent intermediates to the micelles. The presence of the alkyl substituents of ABEI and AHEI provides an additional hydrophobic contribution to the binding process. SDS quenches this reaction as the micelles retain Co(II) on their anionic layer. The protection and stabilization of these luminophores or their luminescent intermediates provided by the cavities of the CDs make this family of cyclic oligosaccharides much more suitable agents than the surfactants for enhancing the CL in aqueous media for this specific reaction.

Chemiluminescent immunoassay technology: what does it change in autoantibody detection?

Diagnostic technology is rapidly evolving, and over the last decade, substantial progress has been made even for the identification of antibodies, increasingly approaching this type of diagnostic to that of automated clinical chemistry laboratory. In this review, we describe the analytical and diagnostic characteristics of chemiluminescence technology in its strength and in its applicability for a more rapid and accurate diagnosis of autoimmune diseases. The wide dynamic range, greater than that of immunoenzymatic methods, the high sensitivity and specificity of the results expressed in quantitative form, the high degree of automation and the clinical implications related to the reduction in the turnaround time, and the ability to run a large number of antibody tests (even of different isotypes), directed towards large antigenic panels in random access mode, make this technology the most advanced in the clinical laboratory, with enormous repercussions on the workflow and on the autoimmunology laboratory organisation. Further improvements are expected in the coming years with the development of new analytical platforms such as the flow-injection chemiluminescent immunoassay, the two-dimensional resolution for chemiluminescence multiplex immunoassay and the magnetic nanoparticles chemiluminescence immunoassay, which will likely result in additional increases in the clinical efficacy of antibody tests.

In vitro effects of very low levels of aflatoxin B1 on free radicals production and bactericidal activity of bovine blood neutrophils

As one of the most potent and hazardous feed/food-originated mycotoxins, aflatoxin (AF) B1 is regarded as a potent immunosuppressor in dairy cows. Neutrophils (PMN), as key effector cells against pathogens, have a high potential to kill engulfed microbes. To investigate the in vitro effects of very low doses of AFB1 on blood PMN functions, we examined the effects of biologically relevant concentrations of AFB1 on the phagocytosis and non-phagocytosis dependent luminol, representative of mainly intracellular free radicals, and isoluminol, representative of mainly extracellular free radicals, chemiluminescence (CL), necrosis and apoptosis of PMN. Isolated blood PMN from healthy dairy cows (n=12) were exposed to 0, 0.01, 0.05 and 0.5ng/ml of AFB1 for 0.5 and 18h depending on the assay. Further, blood PMN of healthy dairy cows (n=8) were exposed to 0.5ng/ml of AFB1 for 3h and myeloperoxidase (MPO) activity, superoxide anion (O2-) production, phagocytosis and killing activities against Staphylococcus (S.) aureus and Escherichia (E.) coli, were examined. Though the effect of extremely low doses of AFB1 were less pronounced, at 0.5ng/ml the production of free radicals was greatly enhanced, especially extracellularly. In contrast to isoluminol CL, the AFB1-treated PMN showed a remarkably impaired phagocytosis-depended luminol CL. PMN necrosis and apoptosis were not affected by AFB1. MPO activity, O2- production, phagocytosis rates and killing of E. coli and S. aureus by AFB1-treated PMN were significantly lower than those of non-treated ones. Our results show the extracellularly pro-oxidant and antiphagocytic properties of very low doses of AFB1 for bovine PMN. The scope of the suppressive effects of the in vitro AFB1 levels on cellular innate immune functions should be considered for high yielding dairy cows.

Chapter 5 Chemiluminescence immunoassays: the early work

At this stage it is possible to appreciate the early developments in chemiluminescence immunoassay and gain an understanding of the approaches used. Though several detailed examples have been discussed, the list is by no means exhaustive as can be seen from the many systems that have been briefly mentioned. It will be seen in Chapter 7 that only a few systems have stood the test of time and have gained acceptance as methods that can be applied to routine analytical situations.

Detection of superoxide anion and hydrogen peroxide production by cellular NADPH oxidases

Background: The recent recognition that isoforms of the cellular NADPH-dependent oxidases, collectively known as the NOX protein family, participate in a wide range of physiologic and pathophysiologic processes in both the animal and plant kingdoms has stimulated interest in the identification, localization, and quantitation of their products in biological settings. Although several tools for measuring oxidants released extracellularly are available, the specificity and selectivity of the methods for reliable analysis of intracellular oxidants have not matched the enthusiasm for studying NOX proteins. Scope of review: Focusing exclusively on superoxide anion and hydrogen peroxide produced by NOX proteins, this review describes the ideal probe for analysis of O2-? and H2O 2 generated extracellularly and intracellularly by NOX proteins. An overview of the components, organization, and topology of NOX proteins provides a rationale for applying specific probes for use and a context in which to interpret results and thereby construct plausible models linking NOX-derived oxidants to biological responses. The merits and shortcomings of methods currently in use to assess NOX activity are highlighted, and those assays that provide quantitation of superoxide or H2O2 are contrasted with those intended to examine spatial and temporal aspects of NOX activity. Major conclusions: Although interest in measuring the extracellular and intracellular products of the NOX protein family is great, robust analytical probes are limited. Several reliable methods for measurement of extracellular O2-? and H2O2 by NOX proteins are available.Chemiluminescent probes for both extracellular and intracellular O2-? and H2O2 detection have shortcomings that limit their use.Options for quantitation of intracellular O2-? and H2O2 are very limited.However, non-redox sensitive probes and genetically encoded reporters promise to provide spatial and temporal detection of O2 -? and H2O2. General significance: The widespread involvement of NOX proteins in many biological processes requires rigorous approaches to the detection, localization, and quantitation of the oxidants produced.

Clinical performance evaluation of a novel rapid response chemiluminescent immunoassay for the detection of autoantibodies to extractable nuclear antigens

Background: We analyzed the performance of a novel ENA screening chemiluminescent immunoassay (CIA) and the confirmation QUANTA Flash tests. Methods: Sera (n = 1079) from patients referred to a rheumatology clinic were screened by QUANTA Flash ENA7 (INOVA Diagnostics). All positive (n = 89) and a matched control group (n = 90) were reflexed for autoantibodies to the individual antigens. Moreover, sera from patients with systemic lupus erythematosus (SLE, n = 252), systemic sclerosis (SSc, n = 64), polymyositis/dermatomyositis (PM/DM, n = 72), Sjoegren’s syndrome (SjS, n = 39) as well as disease controls (n = 605) were tested by ENA7 CIA and by Quanta Lite ENA6 ELISA (INOVA). Results: 89/1079 (8.3%) samples were ENA7 CIA positive with the following reactivity profile: RNP (36.0%), Sm (13.5%), Scl-70 (9.0%), Jo-1 (0.0%), Ro60 (44.9%), Ro52 (39.3%) and SS-B (24.7%). In the negative group, the reactivity profile was: RNP (1.1%), Sm (1.1%), Scl-70 (2.2%) and 0.0% for Jo-1, Ro60, Ro52 and SS-B. The positive/negative/total agreements (ENA7 CIA vs. confirmation assays) were 95.3%/91.5%/93.3%. The sensitivity of the ENA7 CIA was 62.3% in SLE, 54.7% in SSc, 92.3% in SjS, 50.0% in PM/DM, and 61.8% in the total systemic autoimmune rheumatic disease (SARD) population (specificity 95.0%). Conclusion: The QUANTA Flash ENA7 CIA is a reliable screening test.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.SDS of cas: 3682-14-2, you can also check out more blogs about3682-14-2
