AB  - Nucleoside triphosphate diphosphohydrolases (NTPDases) are ecto-enzymes catalyzing the first step of sequential hydrolysis of extracellular ATP to adenosine, as the final product. Among eight members of NTPDase family, NTPDases1-3 have been shown to be expressed in the brain. Although altered NTPDase expression has been observed in relation to cell death and reactive gliosis in several experimentally induced neuropathologies, regulators of NTPDases expression and function are largely unknown. The present study explored the effects of several inflammatory factors (i.e., INF-gamma, TNF-alpha, LPS, peroxide, and glutamate) on NTPDase1-3 activity and expression by cultured cortical astrocytes. We were able to demonstrate that INF-gamma and TNF-alpha increased both ATP and ADP hydrolysis, while LPS specifically increased ATP hydrolysis. Consistent with the observed enhanced nucleotidase activity, INF-gamma induced the upregulation of NTPDase1 at the mRNA and protein level. Furthermore, we were able to demonstrate that INF-gamma and TNF-alpha decreased the relative abundance of dominant astrocytic NTPDase2 in favor of NTPDase1. In summary, these results suggest that INF-gamma, TNF-alpha, and LPS may be relevant in vivo regulators of NTPDase expression in neuropathologies associated with neuroinflammation.

AB  - Experimental autoimmune encephalomyelitis (EAE) is an animal model of CNS inflammatory and demyelinating disease multiple sclerosis. Microglia and astrocytes represent two related cell types involved in the brain pathology in EAE. Accumulations of hypertrophic reactive astrocytes, intensely stained with glial fibrillary acidic protein (GFAP), which also expressed vimentin, are prominent features of EAE lesions. Recent studies from our laboratory reported that ribavirin attenuated the disease process in EAE by reducing clinical and histological manifestations. EAE was induced in genetically susceptible Dark Agouti rats with syngeneic spinal cord homogenate in complete Freund's adjuvant. Real time PCR and immunohistochemistry were used for determination of GFAP and vimentin gene and tissue expression. We have observed the increased gene and tissue expression of GFAP and vimentin in EAE rats. Ribavirin treatment significantly decreased the number of reactive astrocytes at the peak of disease. At the end of the disease, we have observed reactive GFAP(+) and vimentin(+) astrocytes in both immunized and ribavirin-treated groups, accompanied by increased level of GFAP mRNA. The present study indicates that ribavirin may have the ability to attenuate astrocyte proliferation and glial scaring at the peak of the disease and modulate the astroglial response to EAE during the time-course of the disease.

AB  - Objective: To investigate whether hyperbaric oxygenation (HBO) can improve the recovery of motor functions in rats after suction ablation of the right sensorimotor cortex. Methods: The experimental paradigm implies the following groups: Control animals (C), Control+HBO (CHBO), Sham controls (S), Sham control+HBO (SHBO), Lesion group (L), right sensorimotor cortex was removed by suction, Lesion+HBO (LHBO). Hyperbaric protocol: pressure applied 2.5 atmospheres absolute, for 60 minutes, once a day for 10 days. A beam walking test and grip strength meter were used to evaluate the recovery of motor functions. Expression profiles of growth-associated protein 43 (GAP43) and synaptophysin (SYP) were detected using immunohistochemistry. Results: The LHBO group achieved statistically superior scores in the beam walking test compared to the L group. Additionally, the recovery of muscle strength of the affected hindpaw was significantly enhanced after HBO treatment. Hyperbaric oxygenation induced over-expression of GAP43 and SYP in the neurons surrounding the lesion site. Conclusions: Data presented suggest that hyperbaric oxygen therapy can intensify neuroplastic responses by promoting axonal sprouting and synapse remodelling, which contributes to the recovery of locomotor performances in rats. This provides the perspective for implementation of HBO in clinical strategies for treating traumatic brain injuries.

AB  - Aim To evaluate the effect of hyperbaric oxygen therapy (HBOT) on superoxide dismutase 2 (SOD2) expression pattern after the cortical stab injury (CSI). Methods CSI was performed on 88 male Wistar rats, divided into control, sham, lesioned, and HBO groups. HBOT protocol was the following: pressure applied was 2.5 absolute atmospheres, for 60 minutes, once a day for consecutive 3 or 10 days. The pattern of SOD2 expression and cellular localization was analyzed using real-time polymerase chain reaction, Western blot, and double-label fluorescence immunohistochemistry. Neurons undergoing degeneration were visualized with Fluoro-Jade (R) B. Results CSI induced significant transient increase in SOD2 protein levels at day 3 post injury, which was followed by a reduction toward control levels at post-injury day 10. At the same time points, mRNA levels for SOD2 in the injured cortex were down-regulated. Exposure to HBO for 3 days considerably down-regulated SOD2 protein levels in the injured cortex, while after 10 days of HBOT an up-regulation of SOD2 was observed. HBOT significantly increased mRNA levels for SOD2 at both time points compared to the corresponding L group, but they were still lower than in controls. Double immunofluorescence staining revealed that 3 days after CSI, up-regulation of SOD2 was mostly due to an increased expression in reactive astrocytes surrounding the lesion site. HBOT attenuated SOD2 expression both in neuronal and astroglial cells. Fluoro-Jade (R) B labeling showed that HBOT significantly decreased the number of degenerating neurons in the injured cortex. Conclusion HBOT alters SOD2 protein and mRNA levels after brain injury in a time-dependent manner.

AB  - Ecto-5'-nucleotidase (e-5NT) is a cell-surface located, rate-limiting enzyme in the extracellular metabolism of ATP, catalyzing the final step of the conversion of AMP to adenosine. Since this enzyme shifts the balance from pro-inflammatory ATP to anti-inflammatory adenosine, it is considered to be an important regulator of inflammation. Although up-regulation of e-5NT was repeatedly reported in several in vivo models of brain injury, the regulation of its expression and function remains largely unknown. We have studied effects of several pro-inflammatory factors, namely, bacterial endotoxin lipopolysaccharide (LPS), tumor necrosis factor-alpha (TNF-alpha), interferon-gamma (IFN-gamma), glutamate (Glu) and hydrogen peroxide (H2O2) on e-5NT (i) activity, (ii) mRNA expression and (iii) membrane protein abundance in primary cultured cortical astrocytes. We are clearly able to demonstrate a stimulus-specific regulation of the e-5NT pathway. IFN-gamma, LPS, Glu and H2O2 decrease, while TNF-alpha increases e-5NT activity. The analysis of e-5NT gene expression and e-5NT membrane protein levels revealed that tested factors regulate e-5NT at different levels and by employing different mechanisms. In summary, we provide evidence that e-5NT activity is tightly regulated in a stimulus-specific manner. (C) 2012 Elsevier Ltd. All rights reserved.

AB  - Ecto-5'-nucleotidase (CD73; EC 3.1.3.5, e-5NT) is regarded as the key enzyme in the extracellular formation of adenosine, which acts as a neuromodulator and important trophic and homeostatic factor in the brain. In the present study, we have investigated e-5NT activity, kinetic properties concerning AMP hydrolysis and the enzyme protein abundance in the purified synaptic plasma membrane (SPM) preparations isolated from whole female rat brain at different ages. We observed pronounced increase in AMP hydrolyzing activity in SPM during maturation, with greatest increment between juvenile (15-day-old) and pre-pubertal (30-day-old) rats. Immunodetection of e-5NT protein in the SPM displayed the reverse pattern of expression, with the maximum relative abundance at juvenile and minimum relative abundance in the adult stage. Negative correlation between the enzyme activity and the enzyme protein abundance in the SPM indicates that e-5NT has additional roles in the synaptic compartment during postnatal brain development, other than those related to AMP hydrolysis. Determination of kinetic parameters, K(m) and V(max), suggested that the increase in the enzyme activity with maturation was entirely due to the increase in the enzyme catalytic efficiency (V(max)/K(m)). Finally, double immunofluorescence staining against e-5NT and presynaptic membrane marker syntaxin provided first direct evidence for the existence of this ecto-enzyme in the presynaptic compartment. The results of the study suggest that e-5NT may be a part of general scheme of brain development and synapse maturation and provide rationale for the previously reported inconsistencies between enzyme immunohistochemical and biochemical studies concerning localization of e-5NT in the brain.

AB  - Traumatic injury induces massive release of ATP in the extracellular space, where it influences numerous aspects of neuronal, astrocytic, and microglial responses to injury by activating P2X and P2Y receptors. The extracellular ATP actions are controlled by the ectonucleotidase enzyme pathway, which hydrolyses ATP to adenosine at all neuronal and nonneuronal cell types. Adenosine activates its P1 receptors, which have important neuroprotective roles. The rate-limiting enzyme in the ectonucleotidase pathway is ecto-5 '-nucleotidase (e-5NT), which catalyzes the final step of dephosphorylation of AMP to adenosine. The aim of the present study was to characterize the expression pattern and cellular distribution of e-5NT in the perilesioned cortex at 4 hr and 1, 2, 7, and 15 days after unilateral cortical stab injury (CSI). Immunoblot and immunohistochemical studies showed that overall e-5NT expression was lower 4 hr and 1 day postinjury and then gradually increased above the control levels. Double-immunofluorescence studies further showed in control tissue the presence of the enzyme in the membranes surrounding neuronal somata and apical dendrites and less frequently in astrocytes. CSI caused a rapid (after 4 hr) and irreversible loss of the enzyme from neurons, accounting for a decrease in the overall enzyme expression. This was accompanied with a gradual increase in e-5NT-positive astrocytes, accounting for up-regulation of the enzyme levels in the injured area. Thus, CSI induced dynamic changes in the expression pattern of e-5NT that modify the ATP/adenosine ratio and the extent of P1 and P2 receptors activation and, therefore, outcome of the pathological processes after CSI.

AB  - The ecto-nucleoside triphosphate diphosphohydrolase 3 (NTPDase3), an enzyme involved in degradation of extracellular adenosine triphosphate (ATP), is expressed on nerve fibers in different brain regions, including cortex. Here we studied the expression and role of this enzyme after unilateral cortical stab injury in rats. In cortical sections of control rats, NTPDase3 immunoreactivity was associated with two types of fibers: thin processes, occasionally with small mushroom-like protrusions and slightly thicker fibers with more pronounced and more frequent varicosities, whereas immunopositive neuronal perycaria were never observed. Although NTPDase3-positive thin processes and thicker fibers, by general appearance, size and shape, could be dendrites and axons, respectively, they were never immunopositive for microtubule associated protein-2 or neurofilament H subunit. Cortical stab injury induced rapid (within 4 hours) focal varicose swelling that evolved over time to prominent beading of NTPDase3-positive fibers. The NTPDase3-positive fibers in all experimental groups also abundantly express NTPDase1, ecto-5'-nucleotidase and P2X2 receptor channels. Because the brain injury causes a massive ATP release, it is reasonable to conclude that purinoreceptors and ectonucleotidases play an important role in the process of neuritic beading.

AB  - Maintaining the cholesterol homeostasis is essential for normal CNS functioning. The enzyme responsible for elimination of cholesterol excess from the brain is cholesterol 24-hydroxylase (Cyp46). Since cholesterol homeostasis is disrupted following brain injury, in this study we examined the effect of right sensorimotor cortex suction ablation on cellular and temporal pattern of Cyp46 expression in the rat brain. Increased expression of Cyp46 at the lesion site at all post injury time points (2, 7, 14, 28 and 45 days post injury, dpi) was detected. Double immunofluorescence staining revealed colocalization of Cyp46 expression with different types of glial cells in time-dependent manner. In ED1(+) microglia/macrophages Cyp46 expression was most prominent at 2 and 7 dpi, whereas Cyp46 immunoreactivity persisted in reactive astrocytes throughout all time points post-injury. However, during the first 2 weeks Cyp46 expression was enhanced in both GFAP(+) and Vim(+) astrocytes, while at 28 and 45 dpi its expression was mostly associated with GFAP(+) cells. Pattern of neuronal Cyp46 expression remained unchanged after the lesion, i.e. Cyp46 immunostaining was detected in dendrites and cell body, but not in axons. The results of this study clearly demonstrate that in pathological conditions, like brain injury, Cyp46 displayed atypical expression, being expressed not only in neuronal cells, but also in microglia and astrocytes. Therefore, injury-induced expression of Cyp46 in microglial and astroglial cells may be involved in the post-injury removal of damaged cell membranes contributing to re-establishment of the brain cholesterol homeostasis.

AB  - Biochemical properties of nucleotide pyrophosphatase/phosphodiesterase (NPP) in rat serum have been described by assessing its nucleotide phosphodiesterase activity, using p-nitrophenyl-5'-thymidine monophosphate (p-Nph-5'-TMP) as a substrate. It was demonstrated that NPP activity shares some typical characteristics described for other soluble NPP, such as divalent cation dependence, strong alkaline pH optimum (pH 10.5), inhibition by glycosaminoglycans, and K (m) for p-Nph-5'-TMP hydrolysis of 61.8 +/- A 5.2 mu M. In order to characterize the relation between phosphodiesterase and pyrophosphatase activities of NPP, we have analyzed the effects of different natural nucleotides and nucleotide analogs. ATP, ADP, and AMP competitively inhibited p-Nph-5'-TMP hydrolysis with K (i) values ranging 13-43 mu M. Nucleotide analogs, alpha,beta-metATP, BzATP, 2-MeSATP, and dialATP behaved as competitive inhibitors, whereas alpha,beta-metADP induced mixed inhibition, with K (i) ranging from 2 to 20 mu M. Chromatographic analysis revealed that alpha,beta-metATP, BzATP, and 2-MeSATP were catalytically degraded in the serum, whereas dialATP and alpha,beta-metADP resisted hydrolysis, implying that the former act as substrates and the latter as true competitive inhibitors of serum NPP activity. Since NPP activity is involved in generation, breakdown, and recycling of extracellular adenine nucleotides in the vascular compartment, the results suggest that both hydrolyzable and non-hydrolyzable nucleotide analogs could alter the amplitude and direction of ATP actions and could have potential therapeutic application.

AB  - During a variety of insults to the brain adenine nucleotides are released in large quantities from damaged cells, triggering local cellular and biochemical responses to injury. Different models of brain injury reveal that the local increase in adenine nucleotides levels is followed by a compensatory up-regulation of ectonucleotidase enzymes that catalyze sequential hydrolysis of ATP to ADP, AMP and adenosine. However, recent studies imply that changes in adenine nucleotides release may also occur in the areas distant from the site of direct damage. Therefore, in the present study we have used the model of cortical stab injury to analyze extracellular ATP, ADP and AMP hydrolysis in the membrane preparations obtained from the brain regions that were not subjected to direct tissue damage. The brain regions analyzed were contralateral cortex, hippocampus, caudate nucleus, thalamus and hypothalamus. It was evidenced that cortical stab injury induced early widespread decrease in AMP hydrolysis in all brain areas tested, except in the hypothalamus, without changes in ATP hydrolysis. These findings imply that brain injury affects global extracellular adenine nucleotide and nucleoside levels, consequently affecting neuronal function in the regions distant to the primary damage.

AB  - The role of extracellular purines and purinoreceptors in the pathophysiology of different neurological disorders is the focus of rapidly expanding area of research. Ectonucleotidases are the enzymes with multiple roles in extracellular nucleotides metabolism and regulation of nucleotide-based intercellular signaling. The aim of present study was to investigate the changes in the ATP, ADP and AMP hydrolyzing activities after ribavirin treatment in spinal cord during experimental autoimmune encephalomyelitis (EAE). Our results demonstrate that ribavirin itself had no significant effect on ectoenzyme activities, when tested in vitro and in vivo on spinal cord crude membrane preparation of intact animals. We observed significant increase in ATP, ADP and AMP hydrolyzing activity in the spinal cord crude membrane preparation in EAE animals at 15 days post immunization compared to control animals. The increase was registered at 28 days post immunization, as well. At same time points, ribavirin treatment decreased ATP, ADP and AMP hydrolyzing activity compared to EAE animals. In addition, no significant changes 8 days post immunization was observed between EAE-induced and ribavirin- treated EAE animals and these levels were similar to control level. Thus, we suppose that ribavirin-induced alteration in ectonucleotidase activities is rather due to its suppression of inflammation, than to its direct action on ATP, ADP and AMP hydrolysis.

AB  - The aim of the present study was to analyze the activities of extracellular purine metabolizing enzymes, CD39 (apyrase, EC 3.6.1.5) and CD73 (ecto-5' nucleotidase, EC 3.1.3.5) in experimental autoimmune encephalomyelitis (EAE). The levels of ATP, ADP and AMP hydrolysis were analyzed in the blood serum and in the rat spinal cord plasma membrane preparation 8, 15 and 25 days after induction of EAE. The animals were divided in three groups: control (saline), CFA (adjuvant-only) and EAE (CFA and homogenate of spinal cords). Eight days after immunization, ATP, ADP and AMP hydrolysis in the blood serum and spinal cord membrane preparations were unaffected in EAE compared to both, control and CFA group. In the peak of disease, ATP, ADP and AMP hydrolysis in EAE group showed significant decrease in the blood serum and prominent increase in the spinal cord membrane preparation compared to CFA and control group. At the end of illness, as judged by disappearance of clinical manifestation of EAE, ATP, ADP and AMP hydrolysis, although closer to CFA levels, were still significantly different in respect to the CFA group. Modulation of ATP, ADP and AMP hydrolysis suggests that they operate during EAE and might represent the basis of novel therapeutic strategies in immune-mediated diseases, such as MS.

AB  - Experimental autoimmune encephalomyelitis (EAE) is an animal model of multiple sclerosis (MS) and the helpful tool in preclinical testing of various substances considered for treatment of this human CNS disease. Ribavirin (R) and tiazofurin (T) are purine nucleoside analogues, with the broad spectrum of anti-viral, anti-tumoral and anti-inflammatory properties. We proposed that combined treatment with RT, administrated during the effector phase of EAE, would attenuate disease severity, both clinically and pathologically. Ribavirin was given daily at a dosage of 30 mg/kg and tiazofurin was given at a dosage of 10 mg/kg every other day for 15 days. We detected amelioration of clinical signs and faster recovery in the RT group compared to the control group. Immunohistochemical analyses revealed that RT treatment decrease the number of T cells, macrophages and microglia. In the controls, we detected reactive type of microglia, while in the RT group we noticed ramified/resting form. Demyelination areas and axonal damage were not recorded in the RT group, in contrast to the control group where multiple areas of demyelination zones and axonal loss were found. RT combination treatment suppresses ongoing EAE, prevents demyelination and axonal loss, and therefore may well be the potential therapy for the treatment of MS. (C) 2007 Elsevier B.V.

AB  - During a variety of insults to the brain adenine nucleotides are released in large quantities from damaged cells, triggering multiple cellular responses to injury. Here, we evaluated changes in extracellular ATP, ADP and AMP hydrolysis at different times (0-24 hours) after unilateral cortical stab injury (CSI) in adult rats. Results demonstrated that 24 hours following CSI, ATP and ADP hydrolyzing activities were not significantly altered in injured cortex. Based on calculated V (ATP)/V (ADP) ratio it was concluded that ATP/ADP hydrolysis was primarily catalyzed by NTPDase1 enzyme form. In contrast, AMP hydrolysis, catalyzed by 5'-nucleotidase, was significantly reduced at least 4 hours following CSI. Kinetic analysis and Lineweaver-Burk transformation of the enzyme velocities obtained over the range of AMP concentrations (0.05-1.50 mM) revealed that inhibition of 5'-nucleotidase activity after CSI was of the uncompetitive type. Taken together our data suggest that injured tissue has reduced potential for extracellular metabolism of adenine nucleotides in early stages after CSI.

AB  - To determine the mechanism underlying ribavirin induced amelioration of experimental autoimmune encephalomyelitis (EAE), cytokine profiles were evaluated in draining lymph node (DLN) cell culture supernatants and spinal cord obtained from EAE and/or ribavirin-treated EAE Dark Agouti rats. Administration of ribavirin to EAE rats markedly affected the production of pro-inflammatory cytokines IFN-gamma, IL-1 beta and TNF-alpha in DLN and spinal cord, thus shifting the balance towards the anti-inflammatory cytokines IL-10 and TGF-beta. These findings suggest that ribavirin attenuates EAE by limiting cytokine-mediated immunoinflammatory events leading to CNS destruction. The conducted experiments provide rationale for ribavirin to be considered as a candidate drug in the development of new therapeutic strategies for the treatment of autoimmune diseases in humans, such as multiple sclerosis.

AB  - Distribution of two enzymes involved in the ectonucleotidase enzyme chain, ecto-nucleoside triphosphate diphosphohydrolase1 (NTPDase1) and ecto-5'-nucleotidase, was assessed by immunohistochemistry in the rat hippocampus. Obtained results have shown co-expression of the enzymes in the hippocampal region, as well as wide and strikingly similar cellular distribution. Both enzymes were expressed at the surface of pyramidal neurons in the CA1 and CA2 sections, while cells in the CA3 section were faintly stained. The granule cell layer of the dentate gyrus was moderately stained for NTPDase1, as well as for ecto-5'-nucleotidase. Glial association for ecto-5'-nucleotidase was also observed, and fiber tracts were intensively stained for both enzymes. This is the first comparative study of NTPDase1 and ecto-5'-nucleotidase distribution in the rat hippocampus. Obtained results suggest that the broad overlapping distribution of these enzymes in neurons and glial cells reflects the functional importance of ectonucleotidase actions in the nervous system.

AB  - Experimental autoimmune encephalomyelitis (EAE) is an animal model
of human disease multiple sclerosis (MS). Clinical signs of EAE are result of
an autoaggressive T-cell response against myelin. We have previously
shown that combined treatment with nucleoside analogues (ribavirin — R
+tiazofurin — T), inosine monophosphate dehydrogenase inhibitors,
ameliorates clinical signs and histological lesions of EAE in susceptible
rats, when they are given preventatively. The aim of this study was to
investigate the effect of combined treatment with R+T, given with the
appearance of first EAE clinical sign, on microglia and astrocytes response.
These cells of the target tissue also participate in an autoimmune process.
The disease was induced in Dark Agouti rats with rat spinal cord
homogenate and had acute monophasic course. Ribavirin and tiazofurin
were given at a dosage of 30 mg/kg/day and 10 mg/kg every other day, for
15 days, respectively. Control group was immunized and treated with saline.
Amelioration of clinical signs and faster recovery was shown in group
treated with combination of R and T in comparison to control group.
Immunohistochemical analysis of the spinal cord tissue isolated after
15 days of combined therapy revealed decrease in vimentin positive cells
and microglia compared to control group. Additionally, morphology of
GFAP positive (glial fibrillary acid protein) cells and microglia indicated to
reactive type of these cells in control group. Results of this study revealed that R and T modulate glial response and have EAE protective effects when
they are given from the onset of disease.

AB  - Immunohistochemical study was performed to determine distribution of ecto-nucleotide pyrophosphatase/phosphodiesterase1 (NPP1) in adult rat forebrain. The study revealed widespread distribution of NPP1 in rat forebrain, yet with regional differences in the expression pattern and abundance. Strong NPP1 immunoreaction was detected in pyramidal cell layer of cerebral cortex and hippocampus, and in the midline regions of hypothalamus and thalamus. In many immunopositive forebrain areas, NPP1 was mainly localized at neuronal cell bodies. However, prominent immunoreaction was also detected at ependymal cells, tanycytes, endothelial cells of the capillaries and cells of the choroid plexus, suggesting that NPP1 could be involved in some highly specialized transport process.
