Subcortical origins of human and monkey neocortical interneurons

TLDR
It is proposed that the majority of primate neocortical GABAergic interneurons originate from ganglionic eminences of the ventral telencephalon, and this work reveals that the mammalian neocortex shares basic rules for interneuron development, substantially reshaping the understanding of the origin and classification ofPrimate neocortex.
Abstract
In primates, the developmental origin of neocortical interneurons is controversial. Here the authors map out expression patterns of key transcription factors in the developing human and monkey brain and reveal that, just as in rodents, the majority of cortical GABAergic neurons originate from the ganglionic eminences.

The Intricate Epigenetic and Transcriptional Alterations in Pediatric High-Grade Gliomas: Targeting the Crosstalk as the Oncogenic Achilles’ Heel

TL;DR: Molecular specificities of pHGGs subcategories are reviewed in the context of epigenomic rewiring caused by H3 mutations and the subsequent oncogenic interplay with transcriptional signaling pathways co-opted from developmental programs that ultimately leads to gliomagenesis.

Human cortical interneuron development unraveled

Nicoletta Kessaris
- 28 Jan 2022 - 
TL;DR: Paredes et al. as discussed by the authors found a distinctive cellular organization of the embryonic brain area where cortical interneurons are born and an extended period of neurogenesis in humans compared with rodents, explaining how interneuron numbers have increased.

Prenatal betamethasone does not affect glutamatergic or GABAergic neurogenesis in preterm newborns

TL;DR: It is found that prenatal GCs did not affect the densities of radial glia and intermediate progenitors of glutamatergic or GABAergic neurons, and treatment does not significantly impact the balance of glut AMG and GABAergic neurogenesis in premature infants.

Epigenetics in Child Psychiatry

TL;DR: The mechanisms by which epigenetic factors silence or enhance gene expression in child psychiatric disorders remains to be discovered, and recent advances in the role of microRNAs and epigenetic reconfiguration in normal brains will undoubtedly accelerate discoveries.

Altered patterning of interneuron progenitors in Down syndrome

TL;DR: It is suggested that abnormal patterning of human Ts21 interneuron progenitors alters the generation of interneurons in DS and contributes to the reduced neurogenesis in DS.

Model of autism: increased ratio of excitation/inhibition in key neural systems

TL;DR: In this paper, a model that postulates that some forms of autism are caused by an increased ratio of excitation/inhibition in sensory, mnemonic, social and emotional systems is proposed.

Cortical inhibitory neurons and schizophrenia

TL;DR: Convergent findings indicate that a deficiency in signalling through the TrkB neurotrophin receptor leads to reduced GABA synthesis in the parvalbumin-containing subpopulation of inhibitory GABA neurons in the dorsolateral prefrontal cortex of individuals with schizophrenia.

Spatio-temporal transcriptome of the human brain

TL;DR: The generation and analysis of exon-level transcriptome and associated genotyping data, representing males and females of different ethnicities, from multiple brain regions and neocortical areas of developing and adult post-mortem human brains, finds that 86 per cent of the genes analysed were expressed, and that 90 per cent were differentially regulated at the whole-transcript or exon level acrossbrain regions and/or time.

Three groups of interneurons account for nearly 100% of neocortical GABAergic neurons

TL;DR: The universal modulation of these neurons by serotonin and acetylcholine via ionotropic receptors suggests that they might be involved in shaping cortical circuits during specific brain states andbehavioral contexts.

Neurogenic radial glia in the outer subventricular zone of human neocortex

TL;DR: This work finds that OSVZ radial glia-like cells have a long basal process but, surprisingly, are non-epithelial as they lack contact with the ventricular surface, and demonstrates that these cells can undergo proliferative divisions and self-renewing asymmetric divisions to generate neuronal progenitor cells that can proliferate further.
