Transcriptomic Taxonomy and Neurogenic Trajectories of Adult Human, Macaque and Pig Hippocampal and Entorhinal Cells

Project description:The hippocampal-entorhinal system supports cognitive functions, has lifelong neurogenic capabilities in many species, and is selectively vulnerable to Alzheimer’s disease. To investigate neurogenic potential and cellular diversity, we profiled single-nucleus transcriptomes in five hippocampal-entorhinal subregions in human, macaque, and pig. Integrated cross-species analysis revealed robust transcriptomic and histologic signatures of neurogenesis in adult mouse, pig and macaque, but not humans. Doublecortin (DCX), a widely accepted marker of newly generated granule cells, was detected in diverse human neurons, but it did not define immature neuron populations. To explore species differences in cellular diversity and implications for disease, we characterized subregion-specific transcriptomically-defined cell types and transitional changes from the three-layered archicortex to the six-layered neocortex. Notably, METTL7B defined subregion-specific excitatory neurons and astrocytes in primates, associated with endoplasmic reticulum and lipid droplet proteins, including Alzheimer's disease-related proteins. Together this resource reveals cell-type- and species-specific properties shaping hippocampal-entorhinal neurogenesis and function.

Transcription profiling of rat young and aged entorhinal cortex and hippocampus one month after entorhinal administration of BDNF lentivirus

Project description:Patterns of gene expression in the aged entorhinal cortex and hippocampus were examined one month after entorhinal administration of BDNF lentivirus. Whole-genome patterns of expression were examined using Affymetrix arrays four weeks after entorhinal injection of lentiviral-BDNF or GFP injection compared to control subjects. Experiment Overall Design: 27 Samples total: 4 biological replicates of Age rats BDNF treated, 3 biological replicates of Age rats eGFP treated, and 4 biological replicates each of Aged and Young rats controls for the Entorhinal cortex tissue. 2 biological replicates of Age rats BDNF treated, 2 biological replicates of Age rats eGFP treated, and 4 biological replicates each of Age and Young rats controls for the hippocampus tissue.

Proneural genes define ground state rules to regulate neurogenic patterning and cortical folding

Project description:Asymmetric neuronal expansion is thought to drive evolutionary transitions from lissencephalic to gyrencephalic cerebral cortices. We report that Neurog2 and Ascl1 proneural genes interact to sustain neurogenic continuity and lissencephaly in rodents. Using transgenic reporter mice and human cerebral organoids, we found that Neurog2 and Ascl1 expression defines a continuum of four lineage-biased neural progenitor cell (NPC) pools. Double+ NPCs, at the hierarchical apex, are least lineage-restricted due to Neurog2-Ascl1 cross-repression, and display unique features of multipotency (more open chromatin, complex gene regulatory network, G2 pausing). Strikingly, selective killing of double+ NPCs using Neurog2-Ascl1 split-Cre mice and three ‘deletor’ strains breaks neurogenic symmetry by locally disrupting Notch signaling, leading to cortical folding. Consistent with proneural genes driving discontinuous neurogenesis and folding via Notch, NEUROG2, ASCL1 and HES1 transcripts are modular in gyrencephalic macaque cortices. Neurog2/Ascl1 double+ NPCs are thus Notch-ligand expressing ‘niche’ cells that control neurogenic periodicity and cortical gyrification.

Transcriptome from mouse Ts66Yah adult hippocampi and entorhinal cortices

Project description:We have created the Ts66Yah a new model for Down syndrome or T21, derived from the Ts65Dn. Ts66Yah does not contain a set of genes present in 3 copies that are not linked to T21. On this model (Ts66), we performed an RNA seq analysis on 2 structures (hippocampus and entorhinal cortex, ref: S18276) and we have done the same experiment on the Ts65Dn line to compare the 2 models. For this we sampled the hippocampus (hippo) and the entorhinal cortex (EntCortex) from 6 wild-type control male littermate animals and 6 males trisomic individual (Ts66 or Ts65).

Molecular substrates for differences between layers and regions of the entorhinal cortex during postnatal development in rats

Project description:We report the first full transcriptome analysis of layer II and deep layers of the medial and lateral entorhinal cortex during postnatal development. Our analysis showed that postnatal timepoint was the most important element in entorhinal cortex transcriptional dynamics, followed by laminar differences. There were fewer differentially expressed genes between the medial and lateral parts of the entorhinal cortex, and most of these were found in layer II.
