Chemiluminescence

Radioactive reagents have been gradually replaced by nonisotopic reagents for some tasks in molecular biology. Concern over laboratory safety and the economic and environmental aspects of radioactive waste disposal have been key factors in this change. Generally, the new nonisotopic systems have improved in terms of analytical sensitivity and the time required to obtain a result. The most prominent nonisotopic analytical methods exploit chemiluminescence, described here. This technique has been particularly effective when used in combination with an enzyme label, so that the amplifying properties of an enzyme label and the high sensitivity of a chemiluminescent detection reaction are combined to produce an ultrasensitive assay (e.g., chemiluminescent detection of peroxidase- and alkaline phos-phatase-labeled proteins and nucleic acid probes). In all of the commonly used applications in molecular biology, the analytical performance of the chemiluminescent systems approaches that of125I- or32P-based systems. Chemiluminescent systems also avoid the lengthy signal detection times required with32P-based methods, yielding results in minutes rather than days. In addition, chemiluminescent probes can be easily stripped from membranes, allowing the membranes to be reprobed many times without significant loss of resolution. Experimental protocols for directly attaching nonisotopic labels to nucleic acids and indirect labeling methods based on biotin, fluorescein, and digoxigenin labels are now well established. The ancillary reagents (e.g., avidin, streptavidin, antidigoxigenin, and antifluorescein enzyme conjugates) required for the indirect methods are widely available.

Enhanced chemiluminescence detection of glutathione based on isoluminol-PSM nanoparticles probe

In this paper, a new chemiluminescence (CL) strategy was constructed for the determination of physiological thiols by using an isoluminol labeled nano-probe. The amino group on the surface of the magnetic beads (MBs) were converted into pyridyl disulfide groups by treatment with N-succinimidyl-3-(2-pyridyldithio)propionate (SPDP), in the meantime, isoluminol and thiolated signal DNA were labeled on the surface of the polystyrene microspheres (PSMs). By treating the SPDP activated MBs with the modified PSMs, isoluminol molecules on the surface of the PSMs, along with the thiolated signal DNA, were attached to the surface of the MBs through disulfide bonds to form a CL probe. In the presence of glutathione (GSH), the disulfide bonds could be cleaved readily. The isoluminol molecules modified on the surface of the PSMs released from the CL probes were detached by magnetic separation and transferred to the dark closet for CL detection of isoluminol-H2O2-HRP system. Using GSH detection as a model, we prove a linear dose response in the range from 5¡Á10-10 to 8¡Á10-8 M. The detection limit of this trial for GSH determined is 5¡Á10-10 M. The proposed design was successfully applied to the extracts of K562 cell for intracellular thiols detection, the average amount of thiols was about 4.114¡Á10-13 M per K562 cell.

Data on human neutrophil activation induced by pepducins with amino acid sequences derived from beta2AR and CXCR4

The data described here is related to the research article titled (Gabl et al., 2016) [1]. Pepducins with peptide sequence derived from one of the intracellular domains of a given G-protein coupled receptor (GPCR) can either activate or inhibit cell functions. Here we include data on human neutrophil function induced by pepducins derived from beta2AR (ICL3-8) and CXCR4 (ATI-2341), respectively. ICL3-8 exerts neither direct activating effect on the NADPH-oxidase as measured by superoxide release nor inhibitory effect on FPR signaling. ATI-2341 dose-dependently triggers neutrophil activation and these cells were subsequently desensitized in their response to FPR2 specific agonists F2Pal10 and WKYMVM. Moreover, the ATI-2341 response is inhibited by PBP10 and the peptidomimetic Pam-(Lys-betaNSpe)6-NH2 (both are FPR2 specific inhibitors), but not to the FPR1 specific inhibitor cyclosporine H.

Lifestyle and Occupational Stress: A Potential Risk Factor for Obstructive Sleep Apnea in Nonobese Male Subjects

Purpose: To record the incidence of obstructive sleep apnea (OSA) in nonobese male subjects and investigate the coexistence of lifestyle stress, sleep deprivation, and upper airway inflammation. Materials and Methods: 552 patients were assessed during a survey of banks, government and corporate offices, recruitment agencies, and schools between January 2012 and January 2016. After applying the inclusion and exclusion criteria designed for this study, the number of patients tapered down to 120 patients who underwent diagnostic tests, viz. polysomnography, chemiluminiscence immunoassay, nephelometry, and upper airway endoscopy. This revealed the presence of OSA coexistent with elevated serum cortisol, C-reactive protein (CRP), and upper airway inflammation. Results: Polysomnography showed that 57 of 120 patients suffered from OSA. Objective evaluation of these patients exposed an undercurrent of lifestyle stress in 39 patients. CRP and serum cortisol were found to be significantly high (1.60 ¡À 0.52 and 7.20 ¡À 0.76 mug/dL, respectively) in 30 patients. Endoscopy revealed 18 patients with moderate, 7 with severe, and 5 with no upper airway inflammation. Conclusion: The results of this study demonstrated that OSA was found to be prevalent in the cohort of nonobese male patients studied. Coexistence of lifestyle stress, sleep deprivation, and upper airway inflammation was revealed.

Pathogen-mimicking nanocomplexes: self-stimulating oxidative stress in tumor microenvironment for chemo-immunotherapy

A novel drug-loaded pathogen-mimicking nanocomplex has been constructed for synergistic chemo-immunotherapy using detoxified lipopolysaccharide coated mesoporous silica nanoparticle. Detoxified lipopolysaccharide behaves as a dual-purpose entity that not only effectively mimics the function of the natural pathogen for triggering immune responses but also acts as a lid for inhibiting premature chemical drug release. In this approach, a knock-on effect would be observed at site of tumor: firstly, pathogen-mimicries elicited the elevated production of ROS; secondly, excessive production of ROS in turn oxidized the arylboronic ester to realize controlled chemotherapy; thirdly, in addition to inducing ROS generation, the nanocomplex would self-stimulate macrophages activation which subsequently activated cytotoxic T cells. Importantly, chemotherapy and immunotherapy were acting in a synergistic manner to inhibit solid tumor growth. Moreover, chemotherapeutic agents could be effectively released upon exposure to self-stimulating oxidative stress in which external addition of ROS was avoided. This proof of concept might open the door to a new generation of carrier materials in the field of cancer therapy.

Spatial Properties of Reactive Oxygen Species Govern Pathogen-Specific Immune System Responses

Significance: Reactive oxygen species (ROS) are often considered to be undesirable toxic molecules that are generated under conditions of cellular stress, which can cause damage to critical macromolecules such as DNA. However, ROS can also contribute to the pathogenesis of cancer and many other chronic inflammatory disease conditions, including atherosclerosis, metabolic disease, chronic obstructive pulmonary disease, neurodegenerative disease, and autoimmune disease. Recent Advances: The field of ROS biology is expanding, with an emerging paradigm that these reactive species are not generated haphazardly, but instead produced in localized regions or in specific subcellular compartments, and this has important consequences for immune system function. Currently, there is evidence for ROS generation in extracellular spaces, in endosomal compartments, and within mitochondria. Intriguingly, the specific location of ROS production appears to be influenced by the type of invading pathogen (i.e., bacteria, virus, or fungus), the size of the invading pathogen, as well as the expression/subcellular action of pattern recognition receptors and their downstream signaling networks, which sense the presence of these invading pathogens. Critical Issues: ROS are deliberately generated by the immune system, using specific NADPH oxidases that are critically important for pathogen clearance. Professional phagocytic cells can sense a foreign bacterium, initiate phagocytosis, and then within the confines of the phagosome, deliver bursts of ROS to these pathogens. The importance of confining ROS to this specific location is the impetus for this perspective. Future Directions: There are specific knowledge gaps on the fate of the ROS generated by NADPH oxidases/mitochondria, how these ROS are confined to specific locations, as well as the identity of ROS-sensitive targets and how they regulate cellular signaling.

Luminol: Extended hydrogen bond network in water solution

Density functional theory at the B3LYP/6-311G (d, p) level was used to obtain the optimised geometries of a series of luminol-water complexes with stoichiometric ratios ranging from 1:1 to 1:5 both in the gas phase and in aqueous solution. All the calculations show that there are strong hydrogen bond interactions between luminol and water due to the existence of CO, NH, and NH2 groups in luminol molecule. By comparing the relative energy and binding energy, the most stable hydrogen bond complex is suggested, which involves extended hydrogen-bonding networks. Then the changes of luminol geometry structure, charge distribution, frontier orbital properties, and the absorption spectrums induced by hydrogen bond and solvent effects were investigated. The results show that the hydrogen bonds increase the planarity of system, which further decrease the HOMO-LUMO energy gap, and induce maximum absorption shift. This work will be helpful for understanding the effect of hydrogen bond on hydrazide chemiluminescence reagents.

Liquid chromatography of fatty acids with chemiluminescence detection

This paper reviews high-performance liquid chromatographic (HPLC) methods with chemiluminescence (CL) detection for the analysis of biologically important fatty acids. A CL detection method dose not need an exciting light, which can eliminate any scattering of light source. Therefore, the method is highly sensitive owing to a large signal-to-noise ratio (S/N). Further, the method has advantages over other detection method for HPLC – high selectivity, wide dynamic range, and relatively simple instrumentation. Through these advantages, the HPLC with CL detection has increasing importance in the areas of clinical and biomedical analyses. In this review, CL dereivatization reagents for fatty acids and their utilization to the CL detection methods for HPLC were discussed in detail.

Immunization with full-length Plasmodium falciparum merozoite surface protein 1 is safe and elicits functional cytophilic antibodies in a randomized first-in-human trial

A vaccine remains a priority in the global fight against malaria. Here, we report on a single-center, randomized, double-blind, placebo and adjuvant-controlled, dose escalation phase 1a safety and immunogenicity clinical trial of full-length Plasmodium falciparum merozoite surface protein 1 (MSP1) in combination with GLA-SE adjuvant. Thirty-two healthy volunteers were vaccinated at least three times with MSP1 plus adjuvant, adjuvant alone, or placebo (24:4:4) to evaluate the safety and immunogenicity. MSP1 was safe, well tolerated and immunogenic, with all vaccinees sero-converting independent of the dose. The MSP1-specific IgG and IgM titers persisted above levels found in malaria semi-immune humans for at least 6 months after the last immunization. The antibodies were variant- and strain-transcending and stimulated respiratory activity in granulocytes. Furthermore, full-length MSP1 induced memory T-cells. Our findings encourage challenge studies as the next step to evaluate the efficacy of full-length MSP1 as a vaccine candidate against falciparum malaria (EudraCT 2016-002463-33).
