1. Decoding the Transcriptional Response to Ischemic Stroke in Young and Aged Mouse Brain
In this study, we systematically analyzed the impact of aging, stroke, and their interaction on genome-wide expression profiles. We uncovered the downregulation of the transcriptional program that is primarily utilized in PV+ GABAergic interneurons in aged mice. Moreover, an increased activation of type I interferon (IFN-I) signaling represents a key difference in response to stroke between young and aged mice.

2. Chronic alcohol consumption alters extracellular space geometry and transmitter diffusion in the brain
In this translational study, we demonstrate widespread increased mean diffusivity in the brain gray matter of chronically drinking humans and rats. These alterations appear soon after drinking initiation in rats, persist into early abstinence in both species, and are associated with a robust decrease in extracellular space tortuosity explained by a microglial reaction. Mathematical modeling of the diffusivity changes unveils an increased spatial reach of extrasynaptically released transmitters like dopamine that may contribute to progressively enhanced addictive potency of alcohol.
Changes in brain diffusivity caused by chronic alcohol consumption. A: Comparison of MD differences between rats at baseline and after 4 weeks of alcohol drinking (left) and MD differences between controls and alcohol-dependent patients (right) demonstrates a widespread increased mean diffusivity in the brain grey matter of chronically drinking humans as well as rats. B: Experimental design and representative diffusion curves and their parameters obtained in vivo in the somatosensory cortex of a control and an alcohol-exposed rat or in the diluted agar (left). Quantification of volume fraction α and tortuosity λ (right) shows a robust significant decrease in tortuosity with a small decrease in the extracellular volume fraction in alcohol-exposed rats (right). C: Iba-1–positive (Iba-1+) immunostaining in histological sections from representative animals in the two experimental groups (left). Quantification of Iba-1+ cell numbers (right) demonstrates a robust reduction of microglia in alcohol-exposed rats in all studied regions of interest except for caudate putamen (Cg, cingulate cortex; I, insular cortex; S1, primary somatosensory cortex; Hc, hippocampus; Acb, accumbens; CPu, caudate-putamen).

1. The role of AQP4 and TRPV4 channels in the development of cytotoxic edema and associated extracellular diffusion parameter changes.
Our results acquired from different models of cell swellings show, that the AQP4 and TRPV4 channels may play a crucial role in severe pathological states associated with their overexpression and enhanced cell swelling but not during mild stimuli. Moreover, the results indicate a high possibility that besides AQP4, TRPV4 channel may also collaborate with other effector proteins, which can modify its function in cell swelling.

2. The effect of Hapln4 link protein deficiency on extracellular space diffusion parameters and perineuronal nets in the auditory system during aging.
The study show that the ECM composition is altered in the hearing nuclei during aging and brevican/Hapln4- associated perineuronal nets (PNNs) have a protective function against age-evoked changes, particularly in medial nucleus of trapezoid body (MNTB). Hapln4 deficiency and related changes in the ECM composition affect the extracellular diffusion mainly indirectly, via impaired protective function of the PNNs and morphological changes of astrocytes.

3. Sox2 is necessary for the development of olfactory or eye placodes but not for an early neurogenesis of ear.
Transcriptional factor Sox2 is crucial for the maintenance of neurosensory stem cell pluripotency. Using conditional Sox2 knock-outs, we studied the involvement of Sox2 in the development of cranial placodes (eye, ear and olfactory). Sox2 deletion had a prominent inhibitory effect on the development of retina, lens and olfactory placodes as well as on the late development of auditory system, but it did not influence early ear neurogenesis, where other transcriptional factors may play a role.

4. The ability of astrocytes to regulate their volume in the aged hippocampus of GFAP/EGFP mice is markedly altered.
Using the pharmacological inhibitors and the quantification of astrocyte volume changes we showed that the extent of astrocyte swelling during hyperkalemia is altered in aged tissue due to the declined potassium/glutamate clearance and volume regulation and due to a redistribution of transport proteins from astrocytic soma to processes. Disorders in the ion and volume homeostasis is potentiated by a decreased extracellular volume and impaired recovery of the diffusion parameters during washout.

5. Therapeutical properties of iPS-derived neural progenitors seeded on laminin-coated hydrogel in the chronic spinal cord injury.
The study tested the therapeutical properties of a laminin-coated hydrogel with dual porosity, seeded with induced pluripotent stem cell-derived neural progenitors (iPSC-NPs), in a rat model of chronic spinal cord injury (SCI). The implantation of cell-polymer construct into the lesion led to the integration of material into the injured spinal cord, reduced cavitation and supported the iPSC-NPs survival, but did not result in a statistically significant improvement of locomotor recovery.

1. A single-cell analysis reveals multiple roles of oligodendroglial lineage cells during post-ischemic regeneration
Here we identified several yet unknown differences between the gene expression profiles of NG2 cells and oligodendrocytes, and characterized specific genes contributing to oligodendrocyte maturation and phenotypical changes of NG2 cells after focal cerebral ischemia. Moreover, our results suggest that unlike in Alzheimer’s-like pathology, NG2 cells acquire a multipotent phenotype following ischemic injury.
Important roles of oligodendroglial lineage cells during post-ischemic regeneration. NG2 cells acquire a multipotent phenotype after cerebral ischemia; they first participate in the glial scar formation by differentiating into reactive astrocytes, then they give rise to oligodendrocytes – thus taking part in remyelination. Arrows indicate upregulation (green arrows) or downregulation (red arrows) of genes.

1. A deficiency of the link protein Bral2 affects the size of the extracellular space in the thalamus of aged mice
Deficiency in a link protein Bral2, which stabilizes the extracellular matrix complexes, leads to a reduction of perineuronal nets and axonal coats in the thalamic ventral posteromedial nucleus (VPM) of both young and aged mice However, a decrease in the extracellular volume was observed only in aged animals. Our data suggest that the effect of Bral2 deficiency on the VPM diffusion is probably indirect and mediated through the enhanced age-related damage of neurons lacking protective shields.
Age-related changes in thalamic diffusivity and ECM composition in Bral2 deficient mice. Deficiency for a link protein Bral2, associated with a disruption of brevican-based axonal coats (arrow), significantly affect tissue diffusivity in the thalamic ventroposteromedial nucleus in the aged but not in the young mice.

2. Multipotency and therapeutic potential of NG2 cells
Here, we summarize the current knowledge about NG2 cell proliferation, their fate plasticity during embryogenesis and in postnatal CNS under physiological and pathological conditions, with the emphasis on the role of signaling molecules, growth factors, hormones or even neurotransmitters on the fate potential of NG2 cells. They are well-known for their ability to generate new oligodendrocytes, however following CNS injuries, such as demyelination, trauma or ischemia, the proliferative capacity of NG2 cells rapidly increases and their differentiation potential broadens.
During embryogenesis of CNS and postnatally NG2 cells give rise to astrocytes and oligodendrocytes, while following injury they give rise to oligodendrocytes, reactive astrocytes and rarely, to immature neurones.

1. Generation of reactive astrocytes from NG2 cells is regulated by sonic hedgehog
NG2 cells produce oligodendrocytes in the healthy nervous tissue. Under pathological conditions, they display a wide differentiation potential and could give rise to reactive astrocytes. In this study we have shown that morphogene sonic hedgehog (Shh) is an important factor that influences differentiation of NG2 cells into astrocytes during focal cerebral ischemia. We suggest that Shh has a direct influence on the formation and composition of a glial scar, which consequently affects the degree of the brain damage.

2. Brain diffusivity and structural changes in the R6/2 mouse model of Huntington‘s disease
To clarify the nature of brain diffusivity changes in Huntington‘s disease (HD), we correlated results of two diffusion methods with histological tissue analysis. Magnetic resonance changes were mostly related to changes in the extracellular volume associated with a neuronal loss. Different degree of astrogliosis and/or extracellular matrix expression affect the brain diffusion as well and partially compensates the cellular loss, which may result in inconsistent results of numerous HD studies.
Changes in the brain diffusivity and tissue structure in the globus pallidus of R6/2 mouse model of Huntington‘s disease The extracellular volume increase and ADCw decrease in globus pallidus result from the alterations in the tissue structure which may have opposing effect on the brain diffusivity: profound neuronal loss, reduction of extracellular matrix and remodeling of astrocytes due to astrogliosis.

Quantitative Analysis of Glutamate Receptors in Glial Cells from the Cortex of GFAP/EGFP Mice Following Ischemic Injury: Focus on NMDA Receptors
Cortical glial cells contain both ionotropic and metabotropic glutamate receptors. Despite several efforts, a comprehensive analysis of the entire family of glutamate receptors and their subunits present in glial cells is still missing. Here, we provide an overall picture of the gene expression of ionotropic (AMPA, kainate, NMDA) and the main metabotropic glutamate receptors in cortical glial cells isolated from GFAP/EGFP mice before and after focal cerebral ischemia. Employing single cell RT-qPCR, we detected the expression of genes encoding subunits of glutamate receptors in GFAP/EGFP-positive (GFAP/EGFP+) glial cells in the cortex of young adult mice. Most of the analyzed cells expressed mRNA for glutamate receptor subunits, the expression of which, in most cases, even increased after ischemic injury. Data analyses disclosed several classes of GFAP/EGFP+ glial cells with respect to glutamate receptors and revealed in what manner their expression correlates with the expression of glial markers prior to and after ischemia. Furthermore, we also examined the protein expression and functional significance of NMDA receptors in glial cells. Immunohistochemical analyses of all seven NMDA receptor subunits provided direct evidence that the GluN3A subunit is present in GFAP/EGFP+ glial cells and that its expression is increased after ischemia. In situ and in vitro Ca2+ imaging revealed that Ca2+ elevations evoked by the application of NMDA were diminished in GFAP/EGFP+ glial cells following ischemia. Our results provide a comprehensive description of glutamate receptors in cortical GFAP/EGFP+ glial cells and may serve as a basis for further research on glial cell physiology and pathophysiology.
Focal ischemia increases expression of most of the glutamate receptors (GluRs) in GFAP/EGFP glia. As for the NMDA receptor subunits, immunohistochemical analysis confirmed their presence in GFAP/EGFP glia, and their detection was even increased after ischemic insult. The Ca2+ imaging results indicate diminished NMDA receptor Ca2+ permeability after focal ischemia, which is probabl due to the involvement of GluN3A subunit.

1. Increased expression of hyperpolarization-activated cationic channels in reactive astrocytes following ischemia
Following cerebral ischemia we have identified hyperpolarization-activated (HCN) cationic channels in astrocytes. Until now, these channels were described only in neurons. Since HCN channels are mainly permeable for sodium and potassium ions, their increased expression in reactive astrocytes indicates that they may markedly influence the basic astrocytic functions in central nervous system, and consequently, an extent of nervous tissue damage following ischemia. Astrocytic HCN channels could therefore be an important therapeutic target in post-stroke therapy.

2. Altered astrocytic swelling in the cortex of α-syntrophin-negative GFAP/EGFP mice
We have showed that knockout of α-syntrophin, which is a protein responsible for aquaporin-4 anchoring on the astrocytic membrane, aff ects cell swelling/volume regulation in individual astrocytes in situ when exposed to pathological stimuli. Astrocyte volume quantifi cation revealed that α-syntrophin deletion results in signifi cantly smaller/slower astrocyte swelling when induced by severe hypoosmotic stress, oxygen glucose deprivation (OGD) or 50 mM K+.

3. Intracellular Na+ inhibits volume regulated anion channel in rat cortical astrocytes
Using patch clamp technique we have demonstrated that in primary cultured rat cortical astrocytes, elevations of [Na+]i reflecting those achieved during ischemia cause a marked decrease in hypotonicity-evoked current mediated by volume-regulated anion channel (VRAC). These results provide the first evidence that intracellular Na+ dynamics can modulate astrocytic membrane conductance that controls functional processes linked to cell volume regulation and add further support to the concept that limiting astrocyte intracellular Na+ accumulation might be a favorable strategy to counteract the development of brain edema.
High elevation of intracellular sodium (Na+) concentration in cultured rat astrocytes decreases the activity of volume-regulated anion channels (VRAC) measured by patch clamp technique. We speculate that in ischemic conditions intracellular Na+ elevation either through the augmented activity of the Na+-dependent glutamate transporter (GLT-1) or by Na+-permeable channels could modulate the astrocytic volume and glutamate release (Glu-) regulated by VRAC.
