(Submitter supplied) SETD1A, a histone methyltransferase, is a key schizophrenia susceptibility gene. Mutant mice carrying a heterozygous loss-of-function mutation of the orthologous gene exhibit alterations in axonal branching and cortical synaptic dynamics, accompanied by specific deficits in working memory that recapitulates SCZ-related alterations. We show that Setd1a targets mostly enhancers and reveal a striking overlap between Setd1a and Mef2 chromatin targets. more...

(Submitter supplied) Using CRISPR/Cas9 to generate an hiPSC line with SETD1A haploinsufficiency and differentiating it into glutamatergic and GABAergic neurons, we found that SETD1A haploinsufficiency resulted in altered neuronal network activity, which was predominantly defined by increased network burst frequency, whereas unchanged global firing activity.  In individual neurons, this network phenotype was reflected functionally by increased synchronized synaptic inputs and structurally by increased somatodendritic complexity in both glutamatergic and GABAergic neurons. more...

(Submitter supplied) Schizophrenia (SCZ) is a chronic, serious mental disorder with severe burden on patients’ families and society. Although over 100 genes have been linked to SCZ pathogenies, the underlying molecular and cellular mechanisms remain largely unknown. Here, we generated a Setd1a haploinsufficiency mouse model to understand how this SCZ-associated epigenetic factor affects gene expression programs in cells of brain regions highly relevant to SCZ. more...

(Submitter supplied) Brain organoids are promising tools for disease modelling and drug development. For proper neuronal network formation excitatory and inhibitory neurons as well as glia need to co-develop. Here we report the directed differentiation and self-organization of induced pluripotent stem cells in a collagen hydrogel towards a highly interconnected neuronal network in a macroscale tissue format. Bioengineered Neuronal Organoids (BENOs) comprise interconnected excitatory and inhibitory neurons as well as supportive astrocytes and oligodendrocytes. more...

(Submitter supplied) Individuals with 22q11.2 Deletion Syndrome (22q11.2 DS) are a specific high-risk group for developing schizophrenia (SZ), schizoaffective disorder (SAD) and autism spectrum disorders (ASD). Several genes in the deleted region have been implicated in the development of SZ, e.g., PRODH and DGCR8. However, the mechanistic connection between these genes and the neuropsychiatric phenotype remains unclear. more...

(Submitter supplied) We employed a multi-omics approach to study the effects of heterozygous Setd1a LoF on gene expression and synaptic composition in mouse cortex across five developmental timepoints from embryonic day 14 to postnatal day 70. Using RNA sequencing, we observed that Setd1a LoF resulted in the consistent downregulation of genes enriched for mitochondrial pathways. This effect extended to the synaptosome, in which we found age-specific disruption to both mitochondrial and synaptic proteins.

(Submitter supplied) Human brain organoids replicate much of the cellular diversity and developmental anatomy of the human brain. However, the physiology of neuronal circuits within organoids remains under-explored. With high-density CMOS microelectrode arrays and shank electrodes, we captured spontaneous extracellular activity from brain organoids derived from human induced pluripotent stem cells. We inferred functional connectivity from spike timing, revealing a large number of weak connections within a skeleton of significantly fewer strong connections. more...

(Submitter supplied) In our study, we define neural network activities in human cortex+ganglionic eminence (GE) fusion orgaonids using a combination of calcium incator imaging and electrophysiology. We futher define abnormal network activities using fusion organoids generated from isogenic induced pluripotent stem cells containing or lacking MECP2 function derived from Rett syndrome patients. Single cell sequencing (10X genomics) was used to characterize the compositon of the fusion organoids used in our studies, and to define differentially expressed genes associated with MECP2 mutation.
