The model of cerebral cortex neuronal cells metabolism is derived from the community-driven global reconstruction of human metabolism (version 2.02, MODEL1109130000
).
This model is described in the article:
A community-driven global reconstruction of human metabolism.

Abstract:
Multiple models of human metabolism have been reconstructed, but each represents only a subset of our knowledge. Here we describe Recon 2, a community-driven,
consensus 'metabolic reconstruction', which is the most comprehensive representation of human metabolism that is applicable to computational modeling. Compared
with its predecessors, the reconstruction has improved topological and functional features, including ~2x more reactions and ~1.7x more unique metabolites. Using
Recon 2 we predicted changes in metabolite biomarkers for 49 inborn errors of metabolism with 77% accuracy when compared to experimental data. Mapping metabolomic
data and drug information onto Recon 2 demonstrates its potential for integrating and analyzing diverse data types. Using protein expression data, we automatically
generated a compendium of 65 cell type-specific models, providing a basis for manual curation or investigation of cell-specific metabolic properties. Recon 2 will
facilitate many future biomedical studies and is freely available at http://humanmetabolism.org/.

Project description:Stem cell-derived human brain organoids hold an unprecedented degree of promise as experimental models of the human brain. They are, however, plagued by poor reproducibility and high organoid-to-organoid variability. Here, we show that a human organoid model pre-patterned to form the dorsal forebrain and cultured for over six months can achieve reproducible generation of a rich diversity of cell types appropriate for the human cerebral cortex. Using single-cell RNA-sequencing of 166,242 cells isolated from 21 individual organoids, we find that 95% of the organoids generated a virtually indistinguishable compendium of cell types, through the same temporal trajectories, and with organoid-to-organoid variability that is comparable to that of individual endogenous brains. The data demonstrate that reproducible development of complex central nervous system (CNS) cellular diversity does not require the context of the embryo, and that establishment of terminal cell identity is a highly constrained process that can emerge from diverse stem cell origins and growth environments.

Project description:Ischemic stroke is a serious medical condition that leads to neurological symptoms such as loss of motor and cognitive function. Focal cerebral ischemia (FCI) occurs due to interruption of blood supply to the site of injury, leading to the death of brain cells. Cells carrying Neural-glial antigen 2 (NG2) include glial cells serving primarily as olidogendrocyte precursors and a portion of pericytes. NG2 glia proliferate rapidly after ischemia and migrate to the site of injury, participate with astrocytes in glial scar formation, and contribute to the regeneration of the brain tissue. The ability of NG2 glia to differentiate into a different cell type than oligodendrocytes has been described but is still controversial. We therefore isolated NG2 cells and their derivatives labeled with tdTomato red fluorescent protein from the cortex of Rosa26-tdTomato/Cspg4-CreERT2 mice three days after middle cerebral artery occlusion (MCAO). Sham-operated animals were used as healthy controls (CTRL). We aimed to identify NG2 cell types and their derivatives in the cortex of healthy and ischemic mice and determine their incidence as well as characteristic gene expression.

Project description:<p><strong>BACKGROUND:</strong> The protozoan parasite Toxoplasma gondii infects and alters the neurotransmission in cerebral cortex and other brain regions, leading to neurobehavioral and neuropathologic changes in humans and animals. However, the molecules that contribute to these changes remain largely unknown.</p><p><strong>METHODS:</strong> We have investigated the impact of T. gondii infection on the overall metabolism of mouse cerebral cortex. Mass-spectrometry-based metabolomics and multivariate statistical analysis were employed to discover metabolomic signatures that discriminate between cerebral cortex of T. gondii-infected and uninfected control mice.</p><p><strong>RESULTS:</strong> Our results identified 73, 67 and 276 differentially abundant metabolites, which were involved in 25, 37 and 64 pathways at 7, 14 and 21 days post-infection (dpi), respectively. Metabolites in the unsaturated fatty acid biosynthesis pathway were upregulated as the infection progressed, indicating that T. gondii induces the biosynthesis of unsaturated fatty acids to promote its own growth and survival. Some of the downregulated metabolites were related to pathways, such as steroid hormone biosynthesis and arachidonic acid metabolism. Nine metabolites were identified as T. gondii responsive metabolites, namely galactosylsphingosine, arachidonic acid, LysoSM(d18:1), L-palmitoylcarnitine, calcitetrol, 27-Deoxy-5b-cyprinol, L-homophenylalanine, oleic acid and ceramide (d18:1/16:0).</p><p><strong>CONCLUSIONS:</strong> Our data provide novel insight into the dysregulation of the metabolism of the mouse cerebral cortex during T. gondii infection and have important implications for studies of T. gondii pathogenesis.</p>

Project description:Study on selective vulnerability of certain brain regions to oxidative stress. Here we selected 4 brain regions (hippocampal CA1 and CA3, cerebral cortex, and cerebellar granular layer) to study this phenomenon. Experiment Overall Design: Neurons were collected from the 4 regions of the rat brain and subjected to Affymetrix RAE230A analysis, in order to identify genes related to the differential vulnerability of the neurons to oxidative stress.
