Expression data from rat organotypic hippocampal slices lentivirally infected with shRNF10 or scramble construct

ABSTRACT: RNF10 is a synapse-to-nucleus protein messsenger regulating NMDAR-dependent gene trascription. We have charaterized the impact of the absence of RNF10 on structural synaptic plasticity. In this dataset we included expression data from homogenates of DIV14 rat organotypic hippocampal slices lentivirally infected with shRNF10 or scramble construct

NMDA glutamate receptor antagonist MK-801 induces proteome changes in adult human brain slices which are partially counteracted by haloperidol and clozapine

Project description:Deciphering the molecular pathways associated with N-methyl-D-aspartate receptor (NMDAr) hypofunction and its interaction with antipsychotics is necessary to advance our understanding of the basis of schizophrenia, as well as our capacity to treat this disease. In this regard, the development of human brain-derived models amenable for studying the neurobiology of schizophrenia may contribute to fill the gaps led by the widely employed animal models. Here we assessed the proteomic changes induced by the NMDA glutamate receptor antagonist MK-801 on human brain slice cultures obtained from adult donors submitted to resective neurosurgery. Initially, we demonstrated that MK-801 diminishes NMDA glutamate receptor signaling in human brain slices in culture. Next, using mass- spectrometry-based proteomics and systems biology in silico analyses, we found that MK-801 led to alterations in proteins related to several pathways previously associated with schizophrenia pathophysiology including ephrin, opioid, melatonin, sirtuin signaling, interleukin 8, endocannabinoid and synaptic vesicle cycle. We also evaluated the impact of both typical and atypical antipsychotics on MK-801-induced proteome changes. Interestingly, the atypical antipsychotic clozapine showed a more significant capacity to counteract the protein alterations induced by NMDAr hypofunction than haloperidol. Finally, using our dataset we identified potential modulators of the MK-801-induced proteome changes, which may be considered promising targets to treat NMDAr hypofunction in schizophrenia.

Time course of prion infected (RML) and globular domain ligands (POM1) in cultured organotypic cerebellar slices (COCS)

Project description:Cultured organotypic cerebellar slices were exposed for different time points with either prions (RML) versus non-infectious brain homogenate (NBH) or ligands to the globular domain of the prion protein (POM1) vs IgG We used microarrays to characterize the temporal response of two inducers prion protein dependent cell death: COCS were exposed to RML prions or Non-infectious brain homogenate (NBH) and harvested after 14d, 25d, 38d and 45d (4 replicates each condition). COCS were exposed to POM1 or IgG and harvested after 8h, 1d, 3d, 7d, 10d (4 replicates each condition).

Timing of neural responses in cortical organotypic slices.

Project description:Timing is a fundamental part of sensory and motor processing. However, little is known about the neural mechanisms underlying timing in the range of tens to hundreds of milliseconds. Although many theoretical hypotheses have been put forth on the possible underpinnings of temporal processing, there is little cellular experimental data, particularly in vitro, as to the neural mechanisms that could potentially function as timers. We use organotypic cortical slices to show that reliably timed action potentials (or excitatory postsynaptic potentials) can be observed up to 300 ms after a single stimulus. There was no relationship between the latency of the late responses and distance from the stimulating electrode. Paired recordings and pharmacological manipulations suggest that the timed late responses are the result of the propagation of activity throughout functionally defined networks. These results show that cortical networks may be intrinsically able to process temporal information.

A versatile prion replication assay in organotypic brain slices.

Project description:Methods enabling prion replication ex vivo are important for advancing prion studies. However, few such technologies exist, and many prion strains are not amenable to them. Here we describe a prion organotypic slice culture assay (POSCA) that allows prion amplification and titration ex vivo under conditions that closely resemble intracerebral infection. Thirty-five days after contact with prions, mouse cerebellar slices had amplified the abnormal isoform of prion protein, PrP(Sc), >10(5)-fold. This is quantitatively similar to amplification in vivo, but fivefold faster. PrP(Sc) accumulated predominantly in the molecular layer, as in infected mice. The POSCA detected replication of prion strains from disparate sources, including bovines and ovines, with variable detection efficiency. Pharmacogenetic ablation of microglia from POSCA slices led to a 15-fold increase in prion titers and PrP(Sc) concentrations over those in microglia-containing slices, as well as an increase in susceptibility to infection. This suggests that the extensive microglial activation accompanying prion diseases represents an efficacious defensive reaction.

Microcontact Printing of Cholinergic Neurons in Organotypic Brain Slices.

Project description:Alzheimer's disease is a severe neurodegenerative disorder of the brain, characterized by beta-amyloid plaques, tau pathology, and cell death of cholinergic neurons, resulting in loss of memory. The reasons for the damage of the cholinergic neurons are not clear, but the nerve growth factor (NGF) is the most potent trophic factor to support the survival of these neurons. In the present study we aim to microprint NGF onto semipermeable 0.4 μm pore membranes and couple them with organotypic brain slices of the basal nucleus of Meynert and to characterize neuronal survival and axonal growth. The brain slices were prepared from postnatal day 10 wildtype mice (C57BL6), cultured on membranes for 2-6 weeks, stained, and characterized for choline acetyltransferase (ChAT). The NGF was microcontact printed in 28 lines, each with 35 μm width, 35 μm space between them, and with a length of 8 mm. As NGF alone could not be printed on the membranes, NGF was embedded into collagen hydrogels and the brain slices were placed at the center of the microprints and the cholinergic neurons that survived. The ChAT+ processes were found to grow along with the NGF microcontact prints, but cells also migrated. Within the brain slices, some form of re-organization along the NGF microcontact prints occurred, especially the glial fibrillary acidic protein (GFAP)+ astrocytes. In conclusion, we provided a novel innovative microcontact printing technique on semipermeable membranes which can be coupled with brain slices. Collagen was used as a loading substance and allowed the microcontact printing of nearly any protein of interest.

RNA-Seq of rat myocardial slices cultured with biomimetic electromechanical stimulation

Project description:Adult cardiac tissue undergoes a rapid process of dedifferentiation when cultured in vitro. The aim of this experiment was to compare the transcriptome of freshly prepared rat myocardial slices with slices cultured in unloaded conditions (no electromechanical stimulation) for 24 hours, electromechanical stimulation @ SL=1.8 for 24 hours & electromechanical stimulation @ SL=2.2 for 24 hours.
