AB  - Ectonucleoside triphosphate diphosphohydrolase 2 (NTPDase2) hydrolyzes extracellular ATP to ADP, which is the ligand for P2Y1,12,13 receptors. The present study describes the distribution of NTPDase2 in adult rat brains in physiological conditions, and in hippocampal neurodegeneration induced by trimethyltin (TMT). The study also describes the regulation of NTPDase2 by inflammatory mediators in primary astrocytes and oligodendroglial cell line OLN93. In physiological conditions, NTPDase2 protein was most abundant in the hippocampus, where it was found in fibrous astrocytes and synaptic endings in the synaptic-rich hippocampal layers. In TMT-induced neurodegeneration, NTPDase2-mRNA acutely decreased at 2-dpi and then gradually recovered to the control level at 7-dpi and 21-dpi. As determined by immunohistochemistry and double immunofluorescence, the decrease was most pronounced in the dentate gyrus (DG), where NTPDase2 withdrew from the synaptic boutons in the polymorphic layer of DG, whereas the recovery of the expression was most profound in the subgranular layer. Concerning the regulation of NTPDase2 gene expression, proinflammatory cytokines IL-6, IL-1β, TNFα, and IFNγ negatively regulated the expression of NTPDase2 in OLN93 cells, while did not altering the expression in primary astrocytes. Different cell-intrinsic stressors, such as depletion of intracellular energy store, oxidative stress, endoplasmic reticulum stress, and activation of protein kinase C, also massively disturbed the expression of the NTPDase2 gene. Together, our results suggest that the expression and the activity of NTPDase2 transiently cease in neurodegeneration and brain injury, most likely as a part of the acute adaptive response designed to promote cell defense, survival, and recovery.

AB  - Numerous natural compounds, like progesterone (P4), a sex steroid hormone, are highlighted as promising agents for treatment of different disorders including prolonged disturbance of blood flow. However, its action on several oxidative stress markers (pro/antioxidant balance, products of lipid peroxidation and phosphatidylcholine to lysophosphatidylcholine intensity ratio) and one of the major components of antioxidant system, superoxide dismutase in rat prefrontal cortex (PFC) following permanent bilateral occlusion of common carotid arteries (2VO) is not completely investigated. According to the obtained results, levels of investigated oxidative stress markers and SOD activity were altered in 2VO animals treated with vehicle, while P4 treatment returned them to control values. Overall, presented data indicate that P4 might manifest antioxidative features in PFC of 2VO rats.

AB  - Potent neurosteroid progesterone (P4) strongly influences functional recovery in
various models of neurological diseases. However, its protective antioxidative
potential is not well established in stance of chronic cerebral hypoperfusion (CCH)
that induces ischemic milieu in the brain. CCH results in a cascade of events
leading to uncontrolled generation of 4-hydroxynonenal (HNE), a hallmark of
oxidative stress that can be abolished by mitochondrial antioxidant enzyme
manganese superoxide dismutase (MnSOD). Post-ischemic brain regeneration
requires preservation of cerebral blood flow that could be achieved by production of
vasodilatator nitric oxide (NO), synthesized by endothelial NO synthase (eNOS)
whose actions are regulated by phosphorylation at various sites. Decreased
phosphorylation of eNOS at Thr495 during antioxidative response, promotes its
activity and NO production, contributing to neuroprotection. Given the scarcity of
data about P4 antioxidative actions in prefrontal cortex during CCH, current study
assessed the level of HNE and NO, as well as MnSOD activity and the extent of
eNOS phosphorylation at Thr495 in rats subjected to sham operation and injected
with vehicle (commercial flax oil) or animals with permanent occlusion of common
carotid arteries and treated either with vehicle or P4 (1.7 mg/kg/day) for 7 days.
Results indicate that P4 decreases CCH-induced HNE generation and MnSOD
activity, diminishes inactivation of eNOS and increases production of protective NO.
In conclusion, P4 might downscale oxidative stress and boost antioxidant defense
capacity in CCH model, pointing investigated parameters as potential targets of P4
neuroprotective actions. Financially supported by MNTPR RS, grants 173044 and

AB  - Nucleoside triphosphate diphosphohydrolase3 (NTPDase3) is membrane-bound ectoenzyme which hydrolyzes extracellular ATP, thus modulating the function of purinergicreceptors and the pattern of purinergic signaling. Here we analyzed the developmentalexpression of NTPDase3 in female hypothalamus, cerebral cortex and hippocampal formationat different postnatal ages (PD7–PD90) by qRT-PCR and immunohistochemistry. Inhypothalamus and hippocampus, a similar developmental profile was seen: NTPDase3 geneexpression was stable during postnatal development and increased in adults. In the cortex,upregulation of NTPDase3 mRNA expression was seen at PD15 and further increase wasevidenced in adults. Immunohistochemical analysis at PD7 revealed faint neuronal NTPDase3localization, in dorsal hypothalamus. The immunoreactivity (ir) gradually increased in PD15and PD20, in clusters of cells in the lateral, ventral and dorsomedial hypothalamus.Furthermore, in PD20 animals, NTPDase3-ir was detected on short fibers in the posteriorhypothalamic area, while in PD30 the fibers appeared progressively longer and markedlyvaricose. In adults, the strongest NTPDase3-ir was observed in collections of cells indorsomedial hypothalamic nucleus, dorsal and lateral hypothalamus and in several thalamicareas, whereas the varicose fibers traversed entire diencephalon, particularly paraventricularthalamic nucleus, ventromedial and dorsomedial hypothalamic nuclei, the arcuate nucleus andthe prefornical part of the lateral hypothalamus. The presumably ascending NTPDase3-irfibers were first observed in PD20; their density and the varicose appearance increased untilthe adulthood. Prominent enhancement of NTPDase3-ir in the hypothalamus coincides withage when animals acquire diurnal rhythms of sleeping and feeding, supporting the hypothesisthat this enzyme may be involved in regulation of homeostatic functions.
