Astrocyte signaling impacts the effects of human bone marrow mesenchymal stem cells secretome application into the hippocampus: A proliferation and morphometrical analysis on astrocytic cell populations
Publication year: 2020

Abstract/Results: ABSTRACT:
The central nervous system (CNS) has a limited auto-regeneration capacity, which makes it challenging for the development of new therapies. Previous studies from our lab have demonstrated the applicability of human bone marrow mesenchymal stem cells (hBM-MSCs) secretome as a possible therapeutic tool for CNS. Astrocytes, glial cells present in all brain regions, are important players in brain function through their vast influence in extracellular homeostasis, neuro-vascular regulation, synaptic modulation and neurogenesis. Thus, in the present work, we aimed to evaluate the specific impact of MSCs secretome on hippocampal proliferation and astrocyte morphology, in both WT and dnSNARE mice, a transgenic model that presents impaired astrocytic exocytosis and consequently impaired astrocytic function. Results demonstrated increased levels of proliferation for WT when treated with secretome. Additionally, it was possible to observe that dnSNARE animals injected with hBM-MSCs secretome disclosed increased levels of proliferating GFAP stained cells at the SGZ. Morphometrical evaluation found increased process hypertrophy and branching of dnSNARE astrocytes when treated with secretome. These results are closely related with the trophic factors present in the secretome, namely FGF-2, BDNF, GDNF, IGF-1, VEGF, CADH2, PEDF and miR-16. Moreover, the impaired exocytosis of astrocytes may also have implications for the response to the proliferative stimulus, given the established autocrine signaling through this mechanism.

IP3R2 null mice display a normal acquisition of somatic and neurological development milestones
Publication year: 2020

https://onlinelibrary.wiley.com/doi/abs/10.1111/ejn.14724
Abstract/Results: ABSTRACT:
Astrocytes are key players in the regulation of brain development and function. They sense and respond to the surrounding activity by elevating their intracellular calcium (Ca2+) levels. These astrocytic Ca2+ elevations emerge from different sources and display complex spatio-temporal properties. Ca2+ elevations are spatially distributed in global (soma and main processes) and/or focal regions (microdomains). The inositol 1,4,5-triphosphate receptor type 2 knockout (IP3R2 KO) mouse model lacks global Ca2+ elevations in astrocytes and it has been used by different laboratories. However, the constitutive deletion of IP3R2 during development may trigger compensating phenotypes, which could bias the results of experiments using developing or adult mice. To address this issue, we performed a detailed neurodevelopmental evaluation of male and female IP3R2 KO mice, during the first 21 days of life, as well as an evaluation of motor function, strength and neurological reflexes in adult mice. Our results show that male and female IP3R2 KO mice display a normal acquisition of developmental milestones, as compared with wild-type (WT) mice. We also show that that IP3R2 KO mice display normal motor coordination, strength and neurological reflexes in adulthood. To exclude a potential compensatory overexpression of other IP3Rs, we quantified the relative mRNA levels of all 3 subtypes, in brain tissue. We found that, along with the complete deletion of Itpr2, there is no compensatory expression of Itpr1 or Itrp3. Overall, our results show that the IP3R2 KO mouse is a reliable model to study the functional impact of global IP3R2-dependent astrocytic Ca2+ elevations.

Abstract/Results: ABSTRACT:
This paper presents the fabrication of a silicon neural probe using low-cost microfabrication technologies, such as thin-films deposition, blade dicing, and photolithography. The metal stack that forms the 9 microelectrodes of 50?×?50 µm2 area, the tracks and the pads were made of Ti and Pt, while the passivation stack was SiO2 and Si3N4. The fabricated probe was characterized using electrochemical impedance spectroscopy, before and after deposition of poly(3,4-ethylene-dioxythiophene) (PEDOT) on Pt microelectrodes. The electrochemical deposition of PEDOT, a conductive polymer, reduced the impedance of the Pt microelectrodes. The neural probe with PEDOT was used for in vivo electrophysiological acute recordings in an adult rat. The extracellular recordings were filtered to obtain the spike and local field potential (LFP) data, using Butterworth bandpass filters of 400–6000 Hz and 0.1–300 Hz, respectively. The results obtained with the fabricated neural probe validated its functionality, comparing with the signals acquired with a commercial neural probe, and the viability of the fabrication process, which avoids high–cost and complex etching processes.

Astrocyte-mediated switch in spike timing-dependent plasticity during hippocampal development
Publication year: 2020
URL:
https://www.nature.com/articles/s41467-020-18024-4
Abstract/Results: ABSTRACT:
Presynaptic spike timing-dependent long-term depression (t-LTD) at hippocampal CA3-CA1 synapses is evident until the 3rd postnatal week in mice, disappearing during the 4th week. At more mature stages, we found that the protocol that induced t-LTD induced t-LTP. We characterized this form of t-LTP and the mechanisms involved in its induction, as well as that driving this switch from t-LTD to t-LTP. We found that this t-LTP is expressed presynaptically at CA3-CA1 synapses, as witnessed by coefficient of variation, number of failures, paired-pulse ratio and miniature responses analysis. Additionally, this form of presynaptic t-LTP does not require NMDARs but the activation of mGluRs and the entry of Ca2+ into the postsynaptic neuron through L-type voltage-dependent Ca2+ channels and the release of Ca2+ from intracellular stores. Nitric oxide is also required as a messenger from the postsynaptic neuron. Crucially, the release of adenosine and glutamate by astrocytes is required for t-LTP induction and for the switch from t-LTD to t-LTP. Thus, we have discovered a developmental switch of synaptic transmission from t-LTD to t-LTP at hippocampal CA3-CA1 synapses in which astrocytes play a central role and revealed a form of presynaptic LTP and the rules for its induction.

Astrocyte-derived TNF and glutamate critically modulate microglia activation by methamphetamine
Publication year: 2021

Abstract/Results: ABSTRACT:
Methamphetamine (Meth) is a powerful illicit psychostimulant, widely used for recreational purposes. Besides disrupting the monoaminergic system and promoting oxidative brain damage, Meth also causes neuroinflammation, contributing to synaptic dysfunction and behavioral deficits. Aberrant activation of microglia, the largest myeloid cell population in the brain, is a common feature in neurological disorders triggered by neuroinflammation. In this study, we investigated the mechanisms underlying the aberrant activation of microglia elicited by Meth in the adult mouse brain. We found that binge Meth exposure caused microgliosis and disrupted risk assessment behavior (a feature that usually occurs in individuals who abuse Meth), both of which required astrocyte-to-microglia crosstalk. Mechanistically, Meth triggered a detrimental increase of glutamate exocytosis from astrocytes (in a process dependent on TNF production and calcium mobilization), promoting microglial expansion and reactivity. Ablating TNF production, or suppressing astrocytic calcium mobilization, prevented Meth-elicited microglia reactivity and re-established risk assessment behavior as tested by elevated plus maze (EPM). Overall, our data indicate that glial crosstalk is critical to relay alterations caused by acute Meth exposure.

Constitutive deficiency of the neurogenic hippocampal modulator AP2y promotes anxiety-like behavior and cumulative memory deficits in mice from juvenile to adult periods
Publication year: 2021
URL:
https://elifesciences.org/articles/70685
Abstract/Results: ABSTRACT:
The transcription factor activating protein two gamma (AP2?) is an important regulator of neurogenesis both during embryonic development as well as in the postnatal brain, but its role for neurophysiology and behavior at distinct postnatal periods is still unclear. In this work, we explored the neurogenic, behavioral, and functional impact of a constitutive and heterozygous AP2? deletion in mice from early postnatal development until adulthood. AP2? deficiency promotes downregulation of hippocampal glutamatergic neurogenesis, altering the ontogeny of emotional and memory behaviors associated with hippocampus formation. The impairments induced by AP2? constitutive deletion since early development leads to an anxious-like phenotype and memory impairments as early as the juvenile phase. These behavioral impairments either persist from the juvenile phase to adulthood or emerge in adult mice with deficits in behavioral flexibility and object location recognition. Collectively, we observed a progressive and cumulative impact of constitutive AP2? deficiency on the hippocampal glutamatergic neurogenic process, as well as alterations on limbic-cortical connectivity, together with functional behavioral impairments. The results herein presented demonstrate the modulatory role exerted by the AP2? transcription factor and the relevance of hippocampal neurogenesis in the development of emotional states and memory processes.

Beyond new neurons in the adult hippocampus: Imipramine acts as a pro-astrogliogenic factor and rescues cognitive impairments induced by stress exposure
Publication year: 2022

Abstract/Results: Abstract
Depression is a prevalent, socially burdensome disease. Different studies have demonstrated the important role of astrocytes in the pathophysiology of depression as modulators of neurotransmission and neurovascular coupling. This is evidenced by astrocyte impairments observed in brains of depressed patients and the appearance of depressive-like behaviors upon astrocytic dysfunctions in animal models. However, little is known about the importance of de novo generated astrocytes in the mammalian brain and in particular its possible involvement in the precipitation of depression and in the therapeutic actions of current antidepressants (ADs). Therefore, we studied the modulation of astrocytes and adult astrogliogenesis in the hippocampal dentate gyrus (DG) of rats exposed to an unpredictable chronic mild stress (uCMS) protocol, untreated and treated for two weeks with antidepressants—fluoxetine and imipramine. Our results show that adult astrogliogenesis in the DG is modulated by stress and imipramine. This study reveals that distinct classes of ADs impact differently in the astrogliogenic process, showing different cellular mechanisms relevant to the recovery from behavioral deficits induced by chronic stress exposure. As such, in addition to those resident, the newborn astrocytes in the hippocampal DG might also be promising therapeutic targets for future therapies in the neuropsychiatric field.
