Transcriptomic insights into fate choice of pallial versus subpallial GABAergic neurons (CUT&Tag)

ABSTRACT: The connectivity, activity, and plasticity of the telencephalon are shaped by pallial and subpallial GABAergic neurons, two large populations that are produced in the embryonic medial, caudal and lateral ganglionic eminences in a highly complicated manner. Dysregulated development of GABAergic neurons is associated with neuropsychiatric disorders. However, knowledge about the specification of GABAergic neuron subtypes is limited. Here, using single-cell RNA sequencing combined with loss-of-function we delineated developmental trajectories and revealed transcriptional programs that specify GABAergic neuron subtypes in each GE lineage and transcription factors that direct lineage bifurcation decisions. Our study illuminates the control of production between pallial and subpallial populations and offers transcriptomic insights into the pathogenesis of GABAergic neuron-related disorders.

Single cell analysis of the postnatal dorsal V-SVZ reveals a role for Bmpr1a-signaling in silencing pallial germinal activity

Project description:The ventricular-subventricular zone (V-SVZ) is the largest neurogenic region of the postnatal forebrain, containing neural stem cells (NSCs) that emerge from both the embryonic pallium and subpallium. Despite of this dual origin, glutamatergic neurogenesis declines rapidly after birth, while gabaergic neurogenesis persists throughout life. We performed single-cell RNA-sequencing (scRNA-Seq) of the postnatal dorsal V-SVZ for unravelling the mechanisms leading to pallial lineage germinal activity silencing. We show that pallial NSCs enter a state of deep quiescence, characterized by high BMP-signaling, reduced transcriptional activity and Hopx expression, whilst in contrast, subpallial NSCs remain primed for activation. Induction of deep quiescence is paralleled by a rapid blockade of glutamatergic neurons production and differentiation. Finally, manipulation of Bmpr1a demonstrates its key role in mediating these effects. Together, our results highlight a central role of BMP-signaling in synchronizing quiescence induction and blockade of neuronal differentiation to rapidly silence pallial germinal activity after birth.

Mouse and human share conserved transcriptional programs for interneuron development

Project description:Genetic variation confers susceptibility to neurodevelopmental disorders by affecting the development of specific cell types. Changes in cortical and striatal ɣ-aminobutyric acid-expressing (GABAergic) neurons are common in autism and schizophrenia. Here we used single-cell RNA sequencing to characterize the emergence of cell diversity in the human ganglionic eminences, the transitory structures of the human fetal brain where striatal and cortical GABAergic neurons are generated. We identified regional and temporal diversity among progenitor cells underlying the generation of a variety of projection neurons and interneurons. We found that these cells are specified within the human ganglionic eminences by gene regulatory networks similar to those previously identified in rodents. Our findings reveal an evolutionarly conserved regulatory logic controlling the specification, migration, and differentiation of GABAergic neurons in the human telencephalon.

Elucidating ADNP Syndrome Gene Dysregulation through a Novel Approach in iPSC-Derived GABAergic Neuron Development [ADNP_scRNA-seq]

Project description:GABAergic interneurons are essential for maintaining neural circuit function, and their dysfunction is linked to a range of neurodevelopmental and neurodegenerative disorders. Traditional approaches for differentiating human pluripotent stem cells (PSCs) into neuronal cells are often hindered by challenges such as incomplete neural differentiation, prolonged culture times, and variability across PSC lines. To overcome these limitations, we developed an innovative strategy by combining the overexpression of transcription factors Ascl1 and Dlx2 with dual-SMAD and WNT inhibition, effectively driving the differentiation of PSCs into diverse, region-specific GABAergic neuron subtypes. Through single-cell sequencing, we thoroughly characterized the heterogeneity of these induced neurons (iNs) and uncovered the regulatory mechanisms underlying their fate specification. Our findings demonstrate the successful generation of multiple disease-relevant GABAergic neuron types. Furthermore, we investigated the impact of the ADNP syndrome-associated p.Tyr719* variant on GABAergic neuron differentiation, revealing that this mutation significantly alters neuronal subtype composition and synaptic transmission. This study advances our understanding of the diversity of PSC-derived GABAergic neurons and underscores their potential as models for exploring neurological disorders.

Identification of molecular markers for candidate sleep-promoting neurons in CeA using TRAP-seq

Project description:A crucial step in understanding the sleep-control mechanism is to identify sleep neurons. In principle, a neuron could promote sleep by inhibiting wake-promoting neurons. Using rabies virus (RV)-mediated transsynaptic tracing, we identified several brain regions with GABAergic neurons that broadly inhibit multiple wake-promoting neuronal populations, and the most prominent source of GABAergic inputs was found in a posterior part of the CeA. The CeA is known to contain multiple subtypes of GABAergic neurons with distinct molecular markers, projection targets, and functional properties. Using translating ribosome affinity purification (TRAP) RNA-Seq, we identified molecular markers for the canditate sleep-promoting neurons in CeA.
