Abstract
Hydrogen peroxide (H2O2) is known to be generated in Photosystem II (PSII) via enzymatic and non-enzymatic pathways. Detection of H2O2 by different spectroscopic techniques has been explored, however its sensitive detection has always been a challenge in photosynthetic research. During the recent past, fluorescence probes such as Amplex Red (AR) has been used but is known to either lack specificity or limitation with respect to the minimum detection limit of H2O2. We have employed an electrochemical biosensor for real time monitoring of H2O2 generation at the level of sub-cellular organelles. The electrochemical biosensor comprises of counter electrode and working electrodes. The counter electrode is a platinum plate, while the working electrode is a mediator based catalytic amperometric biosensor device developed by the coating of a carbon electrode with osmium-horseradish peroxidase which acts as H2O2 detection sensor. In the current study, generation and kinetic behavior of H2O2 in PSII membranes have been studied under light illumination. Electrochemical detection of H2O2 using the catalytic amperometric biosensor device is claimed to serve as a promising technique for detection of H2O2 in photosynthetic cells and subcellular structures including PSII or thylakoid membranes. It can also provide a precise information on qualitative determination of H2O2 and thus can be widely used in photosynthetic research.

Abstract
Pathogenicity of Chlamydia and Chlamydia-related bacteria could be partially mediated by an enhanced activation of the innate immune response. The study of this host pathogen interaction has proved challenging due to the restricted in vitro growth of these strict intracellular bacteria and the lack of genetic tools to manipulate their genomes. Despite these difficulties, the interactions of Chlamydiales with the innate immune cells and their effectors have been studied thoroughly. This review aims to point out the role of pattern recognition receptors and signal molecules (cytokines, reactive oxygen species) of the innate immune response in the pathogenesis of chlamydial infection. Besides inducing clearance of the bacteria, some of these effectors may be used by the Chlamydia to establish chronic infections or to spread. Thus, the induced innate immune response seems to be variable depending on the species and/or the serovar, making the pattern more complex. It remains crucial to determine the common players of the innate immune response in order to help define new treatment strategies and to develop effective vaccines. The excellent growth in phagocytic cells of some Chlamydia-related organisms such as Waddlia chondrophila supports their use as model organisms to study conserved features important for interactions between the innate immunity and Chlamydia.

Abstract
Electrochemical monitoring of cellular signal transduction under three-dimensional (3-D) cell culture conditions has been demonstrated by combining cell-based microarrays with a secreted alkaline phosphatase (SEAP) reporter system. The cells were genetically engineered to produce SEAP under the control of nuclear factor kappaB (NFkappaB) enhancer elements, and they were embedded with a small volume of a collagen gel matrix on a pyramidal-shaped silicon microstructure. Cellular SEAP expression triggered by NFkappaB activation was assessed by two types of electrochemical systems. First, SEAP expression of a 3-D cell array on a chip was continuously monitored in situ for 2 days by scanning electrochemical microscopy (SECM). Since the SECM-based assay enables the evaluation of cellular respiratory activity, simultaneous measurements of cellular viability and signal transduction were possible. Further, we have developed an electrode-integrated cell culture device for parallel evaluation of cellular SEAP expression. The detector electrode was integrated around the silicon microhole. Two kinds of cells were immobilized on the array of microholes on the same chip for comparative characterization of their SEAP activity. This electrochemical microdevice can be applied to evaluate the SEAP expression activity in multiple cellular microarrays by a high-throughput method.

Abstract
Antimicrobial peptides (AMPs), in addition to their antibacterial properties, are also chemotactic and signalling molecules that connect the innate and adaptive immune responses. The role of AMP [alpha defensins, LL-37, a cathepsin G-derived peptide (CG117-136), protegrins (PG-1), polymyxin B (PMX) and LLP1] in modulating the respiratory burst response in human and murine macrophages in the presence of bacterial endotoxin [lipopolysaccharide (LPS) or lipooligosaccharide (LOS)] was investigated. AMP were found to neutralize endotoxin induction of nitric oxide and TNFalpha release in macrophages in a dose-dependent manner. In contrast, macrophages primed overnight with AMP and LOS or LPS significantly enhanced reactive oxygen species (ROS) release compared with cells primed with endotoxin or AMP alone, while no responses were seen in unprimed cells. This enhanced ROS release by macrophages was seen in all cell lines including those obtained from C3H/HeJ (TLR4-/-) mice. Similar effects were also seen when AMP and endotoxin were added directly with zymosan to trigger phagocytosis and the respiratory burst in unprimed RAW 264.7 and C3H/HeJ macrophages. Amplification of ROS release was also demonstrated in a cell-free system of xanthine and xanthine oxidase. Although AMP inhibited cytokine and nitric oxide induction by endotoxin in a TLR4-dependent manner, AMP and endotoxin amplified ROS release in a TLR4-independent manner possibly by exerting a prolonged catalytic effect on the ROS generating enzymes such as the NADPH-oxidase complex.

Abstract
Chlamydia pneumoniae, a respiratory pathogen implicated in the development and progress of atherosclerosis, is known to infect and survive in macrophages, despite macrophage producing reactive oxygen species (ROS). To gain insight into ROS generation in macrophages infected with C. pneumoniae and to explore factors accounting for their final levels and effect, we investigated the role of NADPH oxidase and cytochrome oxidase pathways in the production and modulation of ROS. We also determined the operational role of Ca2+ signaling in the process. Macrophages stimulated with C. pneumoniae exhibit early release of ROS via up-regulation of NADPH oxidase and cytochrome c oxidase activities. Increasing the dose of C. pneumoniae led to an increase in the expression of these enzymes gene production, which was accompanied by a significant up-regulation of their gene products, implying a probable activation of transcriptional and translational processes, respectively. The change in levels of free Ca2+, influx across plasma membrane and efflux from intracellular store into cytosol all exhibited a significant regulatory role on the ROS generation pathways in macrophages. The observed events were shown to be dependent on binding of C. pneumoniae to CD14 receptors of macrophages. The data reported here imply that macrophages infected with C. pneumoniae produce ROS through membrane-associated NADPH oxidase with oxidative phosphorylation levels depending on Ca2+ influx signals.

Abstract
The intracellular bacterium Chlamydia pneumoniae is involved in the inflammation process of atherosclerosis. We previously demonstrated that C. pneumonia infected monocytes (THP-1 cells) responded to stimulation by an increased respiratory burst linked to an increased NADPH oxidase (NOX) activity. We now tested agents acting on the assembly of the NOX subunits or on protein kinase C, a trigger of NOX activity. Apocynin, resveratrol, rutin, quercetin, curcumin, and tocopherols were tested. The cells were pre-incubated with Chlamydia and the agent for 19 h, and then stimulated with phorbol myristate acetate. The NOX activity was monitored by measuring the hydrogen peroxide production. Resveratrol and curcumin (10(-4)-10(-6) M) were better inhibitors than apocynin. alpha-Tocopherol was inactive, and gamma-tocopherol inhibitor at 10(-4) M only. Quercetin was inactive, and rutin a moderate but significant inhibitor. The inhibition by resveratrol was increased by 10(-6) M rutin or quercetin. Resveratrol and curcumin thus appeared to be interesting for atherosclerosis treatment.

Abstract
Cloning, mutagenesis and complementation of virulence factors are key steps to understand the mechanisms of bacterial pathogenesis and cloning vectors are routinely utilized for these processes. We have investigated the effect of the presence of commonly used cloning vectors on the survival of the intracellular bacterial pathogen Salmonella during macrophage infection. We demonstrate that the presence of the pSC101 derived tetracycline resistance gene on plasmids causes a lower survival rate of Salmonella in macrophages. The decrease in survival caused by the presence of the tet gene was not due to a higher susceptibility to gentamicin, a growth defect, or to increased sensitivity to acid. Higher susceptibility to hydrogen peroxide was observed in vitro for strain containing plasmid with the tet gene when the strains were grown at high densities but not when they were grown at low densities. Our findings demonstrate that the use of the tet gene for mutation or complementation can have deleterious effects and should thus be carefully considered.

Abstract
Chronic inflammation through foam cells and macrophages is important in atherosclerosis development, and can be considered as therapeutic targets. Cyclooxygenase and NADPH-oxidase were expressed within atherosclerotic lesions. Reactive oxygen species produced by NADPH oxidase were found to trigger the cyclooxygenase-2 expression. The effects of preferential COX-2 inhibitors on ROS produced by Chlamydia-primed human monocytes (THP-1 cells) were evaluated by fluorescence, chemiluminescence, oxymetry, and EPR spin trapping. Fluorescence assays showed an increased production of ROS with Chlamydia versus cells primed by 10(-8)M PMA. COX-2 inhibitors inhibited in a dose-dependent manner the luminol-enhanced CL while ibuprofen and diclofenac increased the chemiluminescence response. By EPR spin trapping, COX-2 inhibitors, ibuprofen, and diclofenac, exhibited a dose-dependent inhibiting effect (10 and 100muM) on the EPR signal appearance. Our cell model combining EPR, chemiluminescence, and oxymetry appeared relevant to study the modulating effects of preferential COX-2 inhibitors on the cell oxidant activity and chronic inflammatory diseases.

Abstract
We previously observed that the respiratory burst of human monocytes (THP-1 cell line) triggered by phorbol myristate acetate was strongly enhanced by a priming of the cells by Chlamydia pneumoniae [Biochem. Biophys. Res. Commun. 287 (2001) 781]. We describe here the modifications of the responses of Chlamydia-primed THP-1 cells to hydrocortisone (HCT) and methylprednisolone (MPL). HCT and MPL inhibited the production of the cytokines TNFalpha and IL-8. But HCT, which inhibited the respiratory burst in LPS-primed monocytes, paradoxically stimulated the phenomenon in Chlamydia-primed cells; MPL exerted no significant effect. Both glucocorticoids did not significantly modify the triggering effect of Chlamydia on NF-kappaB binding activity. On the expression of p22(phox), a protein subunit of the NADPH oxidase, HCT had an increasing and MPL a decreasing effect. Glucocorticoids thus had unexpected effects on the inflammatory response of Chlamydia-primed monocytes.

Abstract
Chlamydia pneumoniae, a respiratory pathogen, has been suggested as a risk factor for cardiovascular disease. Epidemiologic data are very controversial. Histopathologic and microbiologic studies have established an association between atherosclerosis and presence of C. pneumoniae, consistently finding C. pneumoniae DNA and antigens in atherosclerotic arteries. C. pneumoniae has been cultured from atherosclerotic arteries in several centers. An etiologic role for C. pneumoniae in initiation, acceleration of atherosclerosis, and/or acute ischemia remains debatable. In vitro studies have shown that C. pneumoniae can induce foam cell formation, low-density lipoprotein oxidation, and proinflammatory and procoagulant cytokine expression. Animal models of de novo initiation or enhancement of atherosclerosis have been developed. Preliminary trials of secondary prevention of coronary artery disease complications by antimicrobial agents show modest results. Better diagnostic tools, more diverse animal models, and clinical trials of primary prevention are needed. Meanwhile, results of ongoing large clinical trials on secondary prevention are eagerly awaited, but may not be definitive.
