Evolution of the mammalian dentate gyrus [PDF]

Journal of Comparative Neurology, 2015
ABSTRACTThe dentate gyrus (DG), a part of the hippocampal formation, has important functions in learning, memory, and adult neurogenesis. Compared with homologous areas in sauropsids (birds and reptiles), the mammalian DG is larger and exhibits qualitatively different phenotypes: 1) folded (C‐ or V‐shaped) granule neuron layer, concave toward the hilus

CRISPRa Lipid Nanocomplex‐Mediated Mt3 Targeting Enhances Astrocytic Endocytosis of Amyloid‐β in an Alzheimer's Disease Mouse Model

Advanced Science, EarlyView.
GeTe exhibits intrinsically high carrier concentrations that limit its thermoelectric performance. Herein, CuAgSe alloying synergistically tunes the band structure, induces band flattening and valence‐band convergence, promotes Cu‐ion delocalization, and generates multiscale hierarchical structures to suppress phonon transport.

Prox1 is required for granule cell maturation and intermediate progenitor maintenance during brain neurogenesis.

PLoS Biology, 2010
The dentate gyrus has an important role in learning and memory, and adult neurogenesis in the subgranular zone of the dentate gyrus may play a role in the acquisition of new memories.

Gestational diabetes induces neuronal loss in dentate gyrus in rat offspring [PDF]

, 2014
Background: This study was conducted to determine the effect of gestational diabetes on neuronal density in the dentate gyrus (DG) subfields of hippocampus in rats offspring. Methods: On day 1 of gestation, 10 dams randomly allocated into two control and

Effect of scopolamine-based amnesia on the number of astrocytes in the rat's hippocampus [PDF]

, 2012
As neuron-astrocyte interactions play a crucial role in the adult brain, it is thought that astrocytes support learning and memory through specific mechanisms.

Elevated Apolipoprotein E Expression in Hippocampal Microglia Drives Temporal Lobe Epilepsy Progression

Advanced Science, EarlyView.
In temporal lobe epilepsy, hippocampal APOE is markedly upregulated predominantly in microglia. APOE overexpression in microglia drives TLR4 and cGAS/STING‐dependent neuroinflammation, engages bidirectional crosstalk with neurons and astrocytes, increases neuronal excitability, and perturbs hippocampal lipid metabolism. These findings suggest that APOE‐

Modifying Glucose Metabolism Reverses Memory Defects of Alzheimer's Disease Model at Late Stages

Advanced Science, EarlyView.
Using spatial transcriptomics, we show that ferul enanthate (SL‐ZF‐01) reverses episodic‐like memory deficits in aged, but not young, Alzheimer’s disease (AD) mice. SL restores glucose metabolism and Glucose Transporter 1/3 expression via an ‘Aging‐AD‐Rescue’ pattern, rescuing deficits seen in aged AD mice.

Reelin Mediates Hippocampal Cajal-Retzius Cell Positioning and Infrapyramidal Blade Morphogenesis

Journal of Developmental Biology, 2020
We have previously described hypomorphic reelin (Reln) mutant mice, RelnCTRdel, in which the morphology of the dentate gyrus is distinct from that seen in reeler mice.
