Abstract
Renal ischemia/reperfusion (I/R) is characterized by severe inflammatory damage. We assessed the effect of administrating recently developed nitrosothiol compounds acting as nitric oxide (NO) donors on the production of cytokines and other markers of acute inflammatory reaction in an experimental model of warm (I/R), and in a model of cold ischemia and transplant in rats. Warm ischemia was achieved by ligation of left renal pedicle for 60 min, followed by contralateral nephrectomy. NO-donors LA-803, LA-807, LA-810 were administered i.v. (1.8 micromol/kg) during 30 min before reperfusion. Cold ischemia was achieved by preservating the kidney for 24 h in Euro Collins and grafting it in consanguineous Fisher 344/Ico rats. LA-803 was administered in the preservation fluid and in the recipient rat. Reperfusion time was 4 h in warm ischemia and 3 h in cold ischemia + transplantation. Administration of LA-803, LA-807 and, in a lower proportion, LA-810 prevented from the enhanced production of tumor necrosis factor (TNF), interferon-gamma (IFN-gamma), and interleukin-1beta (IL-1beta), the decrease in interleukin-6 (IL-6) and interleukin-10 (IL-10), the increase in tissue level of superoxide anion (SOA) and superoxide dismutase (SOD), and the increase in neutrophil infiltration induced by warm I/R. Treatment with LA-803 in animals with renal transplantation after cold ischemia was also associated with reduced plasma levels of TNF, IFN-gamma, and IL-1beta, increased plasma levels of IL-6 and IL-10, reduced renal levels of SOA and SOD, and reduced neutrophil infiltration. These data demonstrate that systemic administration of new NO-donors with nitrosothiol structure diminished inflammatory responses in a kidney subjected to warm I/R or cold ischemia and transplantation.

Abstract
Peroxynitrite--the product of the diffusion-controlled reaction of nitric oxide with superoxide radical--is a short-lived oxidant species that is a potent inducer of cell death. Conditions in which the reaction products of peroxynitrite have been detected and in which pharmacological inhibition of its formation or its decomposition have been shown to be of benefit include vascular diseases, ischaemia-reperfusion injury, circulatory shock, inflammation, pain and neurodegeneration. In this Review, we first discuss the biochemistry and pathophysiology of peroxynitrite and then focus on pharmacological strategies to attenuate the toxic effects of peroxynitrite. These include its catalytic reduction to nitrite and its isomerization to nitrate by metalloporphyrins, which have led to potential candidates for drug development for cardiovascular, inflammatory and neurodegenerative diseases.

Abstract
INTRODUCTION Although exposure to diesel exhaust has been linked with adverse health effects, little is known about the acute effects of exposure in the underground workplace. METHODS Cross-shift spirometry and sputum induction were completed on twelve subjects associated with comminuted rock removal (mucking) operations in an underground copper mine using diesel powered and pneumatic equipment on separate days, and sputum collected on a baseline non-exposure day as well. RESULTS For diesel operations, elemental carbon exposure averaged 538 +/- 512 microg/m(3) during the 1-2 hour operations. Sputum interleukin-10 decreased with diesel exhaust using one ELISA assay (3.69 v. 2.32 pg/ml, p = 0.015), but increased when measured with a different ELISA kit (0.18 v. 0.59 pg/ml, p = 0.019), consistent with an overall decline in IL-10 protein concentration but an increase in the biologically active form. Sputum interleukin-6 decreased with exposure to diesel exhaust, although this change lost statistical significance when restricted to non-smokers. There were no significant changes in spirometry, interleukins 1beta, 4, and 8, tumor necrosis factor alpha or 8-hydroxy-2'-deoxyguanosine. CONCLUSION High levels of diesel exhaust can result in rapid changes in sputum IL-10, suggesting possible protein modification.

Abstract
To investigate the upstream effector that led to tau hyperphosphorylation, nitration, and accumulation as seen in Alzheimer's disease brain, and the underlying mechanisms, we bilaterally injected SIN-1, a recognized peroxynitrite donor, into the hippocampus of rat brain. We observed that the level of nitrated and hyperphosphorylated tau was markedly increased in rat hippocampus 24 h after drug administration, and these alterations were prevented by preinjection of uric acid, a natural scavenger of peroxynitrite. Concomitantly, we detected a significant activation in glycogen synthase kinase-3beta (GSK-3beta) and p38 MAPKs, including p38alpha, p38beta, and p38delta, but no obvious change was measured in the activity of p38gamma, ERK, and c-Jun amino-terminal kinase (JNK). Both nitrated tau and hyperphosphorylated tau were aggregated in the hippocampus, in which the activity of 20S proteasome was significantly arrested in SIN-1-injected rats. Further studies demonstrated that the hyperphosphorylated tau was degraded as efficiently as normal tau by 20S proteasome, but the nitrated tau with an unorderly secondary structure became more resistant to the proteolysis. These results provide the first in vivo evidence showing that peroxynitrite simultaneously induces tau hyperphosphorylation, nitration, and accumulation, and that activation of GSK-3beta, p38alpha, p38beta, p38delta isoforms and the inhibition of proteasome activity are respectively responsible for the peroxynitrite-induced tau hyperphosphorylation and accumulation. Our findings reveal a common upstream stimulator and a potential therapeutic target for Alzheimer-like neurodegeneration.

Abstract
Ischemia reperfusion (I-R)-induced renal damage is reduced by systemic administration of the NO-dependent vasodilator molsidomine. The aim of this study was to estimate the effect of direct intrarenal molsidomine administration on renal dysfunction and inflammatory reaction after experimental I-R in rats, in order to assess only renal NO effects and to obviate its systemic hemodynamic action. Ischemia was induced by renal pedicle ligation (60 min) followed by reperfusion and contralateral nephrectomy. Molsidomine (4 mg/kg) was infused into the renal artery 15 min before reperfusion and its effects were compared with those of the NO-independent vasodilator hydralazine (2 mg/kg). Survival rates after 7 days were 100% in the sham-operated group and 75% in the I-R rats. Molsidomine treatment almost completely prevented the I-R-induced renal dysfunction, and survival reached 100%. Molsidomine prevented an I-R-induced increase in superoxide anion and reduced plasma levels of pro-inflammatory cytokines (TNF-alpha, IL-1beta and IFN-gamma), whereas it enhanced anti-inflammatory cytokines (IL-6 and IL-10). Inflammatory cell infiltration and cell-adhesion molecules (ICAM-1, PECAM-1, VCAM-1 and P-selectin) were lower in the molsidomine-treated kidneys than in the untreated animals. All these protective effects were not observed after hydralazine administration. In conclusion, intrarenal administration of molsidomine before reperfusion improved renal function and decreased inflammatory responses after I-R.

Abstract
Nitric oxide has been implicated as an effector cytotoxic molecule in trypanosomiasis. In this work, we investigated the presence of circulating antibodies directed against nitrosylated epitopes as biological indicators for nitric oxide (NO) production in the sera of trypanosome-infected mice. We tested these sera with synthetic antigens, such as S-nitrosated protein or nitrosylated conjugates of amino acids that possess a high affinity to NO, by an immunoenzymatic assay. We detected antibodies directed against nitroso epitopes in the sera of infected mice, as compared to non-infected control mice. The antibody response was linked to the IgM isotype. Our results indicate the production of NO and its derivatives in trypanosomiasis. This production may potentially induce the synthesis of nitroso epitopes in vivo and favor the development of a humoral immune response.

Abstract
It has recently emerged that posttranslational modification of proteins via nitration of tyrosine residues can alter their function. In this study, we describe that specific nitration of the glucocorticoid receptor (GR) by NCX-1015, a novel NO-donating prednisolone derivative (prednisolone 21-[4'-(nitrooxymethyl)benzoate), results in an enhancement of GR-mediated events. Incubation of PBMC and U937 cells with 1-10 micro M NCX-1015 caused faster activation of GR as assessed by augmented 1) binding to [(3)H]dexamethasone, 2) dissociation from heat shock protein 90, and 3) nuclear translocation. PBMCs treated with NCX-1015 contained GR that had undergone tyrosine nitration. The chemistry facilitating the increase in steroid binding capacity observed with NCX-1015 is specific, because changing the position of the NO-donating group or ubiquitous nitration by addition of an NO donor was unable to mimic this event. In vivo treatment with NCX-1015 provoked GR nitration and faster heat shock protein 90 dissociation as assessed in peritoneal cells. Accordingly, NCX-1015, but not prednisolone or other derivatives, produced a rapid inhibition of the early neutrophil recruitment and mediator generation in a model of peritonitis. In conclusion, we report here for the first time that posttranslational modification of GR by this novel nitrosteroid is associated with its enhanced anti-inflammatory activity.

Abstract
Peroxynitrite, formed by nitric oxide and superoxide, has been shown to nitrate and reduce the function of proinflammatory proteins such as interleukin (IL)-8, monocyte chemoattractant protein-1, and eotaxin, but in contrast, to enhance the function of the anti-inflammatory cytokine IL-10 in reducing IL-1 release from blood monocytes. However, the effect of nitrated IL-10 on release of proinflammatory cytokines from lung epithelial cells is unknown. We hypothesized that peroxynitrite would enhance the capacity of human IL-10 to reduce inflammatory mediators released by epithelial cells. To test this hypothesis, recombinant human IL-10 was evaluated for its capacity to attenuate the release of neutrophil chemotactic activity and IL-8 from a human epithelial cell line in response to IL-1 beta and tumor necrosis factor-alpha. Neutrophil chemotactic activity and IL-8 in lung epithelial culture supernatant fluids were significantly lower after culture with nitrated human IL-10 compared with non-nitrated human IL-10 controls (P < 0.05). Consistent with these results, nitrated human IL-10 attenuated IL-8 mRNA expression more than non-nitrated human IL-10 controls (P < 0.05). These data demonstrate that peroxynitrite exposed human IL-10 has enhanced anti-inflammatory activity and suggest that nitration may play a critical role in the regulation of inflammation within the lower respiratory tract.
