text: Mutations in the chromodomain helicase DNA-binding 8 (CHD8) gene are a frequent
cause of autism spectrum disorder (ASD). While its phenotypic spectrum often encompasses
macrocephaly, implicating cortical abnormalities, how CHD8 haploinsufficiency
affects neurodevelopmental is unclear. Here, employing human cerebral organoids,
we find that CHD8 haploinsufficiency disrupted neurodevelopmental trajectories
with an accelerated and delayed generation of, respectively, inhibitory and excitatory
neurons that yields, at days 60 and 120, symmetrically opposite expansions in
their proportions. This imbalance is consistent with an enlargement of cerebral
organoids as an in vitro correlate of patients’ macrocephaly. Through an isogenic
design of patient-specific mutations and mosaic organoids, we define genotype-phenotype
relationships and uncover their cell-autonomous nature. Our results define cell-type-specific
CHD8-dependent molecular defects related to an abnormal program of proliferation
and alternative splicing. By identifying cell-type-specific effects of CHD8 mutations,
our study uncovers reproducible developmental alterations that may be employed
for neurodevelopmental disease modeling.

text: "Autism spectrum disorders (ASDs) are a group of neurodevelopmental disorders
character\x02ized by behavioral symptoms such as problems in social communication
and interaction, as\r\nwell as repetitive, restricted behaviors and interests.
These disorders show a high degree\r\nof heritability and hundreds of risk genes
have been identifed using high throughput\r\nsequencing technologies. This genetic
heterogeneity has hampered eforts in understanding\r\nthe pathogenesis of ASD
but at the same time given rise to the concept of convergent\r\nmechanisms. Previous
studies have identifed that risk genes for ASD broadly converge\r\nonto specifc
functional categories with transcriptional regulation being one of the biggest\r\ngroups.
In this thesis, I focus on this subgroup of genes and investigate the gene regulatory\r\nconsequences
of some of them in the context of neurodevelopment.\r\nFirst, we showed that mutations
in the ASD and intellectual disability risk gene Setd5 lead\r\nto perturbations
of gene regulatory programs in early cell fate specifcation. In addition,\r\nadult
animals display abnormal learning behavior which is mirrored at the transcriptional\r\nlevel
by altered activity dependent regulation of postsynaptic gene expression. Lastly,\r\nwe
link the regulatory function of Setd5 to its interaction with the Paf1 and the
NCoR\r\ncomplex.\r\nSecond, by modeling the heterozygous loss of the top ASD gene
CHD8 in human cerebral\r\norganoids we demonstrate profound changes in the developmental
trajectories of both\r\ninhibitory and excitatory neurons using single cell RNA-sequencing.
While the former\r\nwere generated earlier in CHD8+/- organoids, the generation
of the latter was shifted to\r\nlater times in favor of a prolonged progenitor
expansion phase and ultimately increased\r\norganoid size.\r\nFinally, by modeling
heterozygous mutations for four ASD associated chromatin modifers,\r\nASH1L, KDM6B,
KMT5B, and SETD5 in human cortical spheroids we show evidence of\r\nregulatory
convergence across three of those genes. We observe a shift from dorsal cortical\r\nexcitatory
neuron fates towards partially ventralized cell types resembling cells from the\r\nlateral
ganglionic eminence. As this project is still ongoing at the time of writing,
future\r\nexperiments will aim at elucidating the regulatory mechanisms underlying
this shift with\r\nthe aim of linking these three ASD risk genes through biological
convergence."

text: Mutations affecting mTOR or RAS signaling underlie defined syndromes (the
so-called mTORopathies and RASopathies) with high risk for Autism Spectrum Disorder
(ASD). These syndromes show a broad variety of somatic phenotypes including cancers,
skin abnormalities, heart disease and facial dysmorphisms. Less well studied are
the neuropsychiatric symptoms such as ASD. Here, we assess the relevance of these
signalopathies in ASD reviewing genetic, human cell model, rodent studies and
clinical trials. We conclude that signalopathies have an increased liability for
ASD and that, in particular, ASD individuals with dysmorphic features and intellectual
disability (ID) have a higher chance for disruptive mutations in RAS- and mTOR-related
genes. Studies on rodent and human cell models confirm aberrant neuronal development
as the underlying pathology. Human studies further suggest that multiple hits
are necessary to induce the respective phenotypes. Recent clinical trials do only
report improvements for comorbid conditions such as epilepsy or cancer but not
for behavioral aspects. Animal models show that treatment during early development
can rescue behavioral phenotypes. Taken together, we suggest investigating the
differential roles of mTOR and RAS signaling in both human and rodent models,
and to test drug treatment both during and after neuronal development in the available
model systems

text: De novo protein synthesis is required for synapse modifications underlying
stable memory encoding. Yet neurons are highly compartmentalized cells and how
protein synthesis can be regulated at the synapse level is unknown. Here, we characterize
neuronal signaling complexes formed by the postsynaptic scaffold GIT1, the mechanistic
target of rapamycin (mTOR) kinase, and Raptor that couple synaptic stimuli to
mTOR-dependent protein synthesis; and identify NMDA receptors containing GluN3A
subunits as key negative regulators of GIT1 binding to mTOR. Disruption of GIT1/mTOR
complexes by enhancing GluN3A expression or silencing GIT1 inhibits synaptic mTOR
activation and restricts the mTOR-dependent translation of specific activity-regulated
mRNAs. Conversely, GluN3A removal enables complex formation, potentiates mTOR-dependent
protein synthesis, and facilitates the consolidation of associative and spatial
memories in mice. The memory enhancement becomes evident with light or spaced
training, can be achieved by selectively deleting GluN3A from excitatory neurons
during adulthood, and does not compromise other aspects of cognition such as memory
flexibility or extinction. Our findings provide mechanistic insight into synaptic
translational control and reveal a potentially selective target for cognitive

text: Chronic psychological stress is one of the most important triggers and environmental
risk factors for neuropsychiatric disorders. Chronic stress can influence all
organs via the secretion of stress hormones, including glucocorticoids by the
adrenal glands, which coordinate the stress response across the body. In the brain,
glucocorticoid receptors (GR) are expressed by various cell types including microglia,
which are its resident immune cells regulating stress-induced inflammatory processes.
To study the roles of microglial GR under normal homeostatic conditions and following
chronic stress, we generated a mouse model in which the GR gene is depleted in
microglia specifically at adulthood to prevent developmental confounds. We first
confirmed that microglia were depleted in GR in our model in males and females
among the cingulate cortex and the hippocampus, both stress-sensitive brain regions.
Then, cohorts of microglial-GR depleted and wild-type (WT) adult female mice were
housed for 3 weeks in a standard or stressful condition, using a chronic unpredictable
mild stress (CUMS) paradigm. CUMS induced stress-related behavior in both microglial-GR
depleted and WT animals as demonstrated by a decrease of both saccharine preference
and progressive ratio breakpoint. Nevertheless, the hippocampal microglial and
neural mechanisms underlying the adaptation to stress occurred differently between
the two genotypes. Upon CUMS exposure, microglial morphology was altered in the
WT controls, without any apparent effect in microglial-GR depleted mice. Furthermore,
in the standard environment condition, GR depleted-microglia showed increased
expression of pro-inflammatory genes, and genes involved in microglial homeostatic
functions (such as Trem2, Cx3cr1 and Mertk). On the contrary, in CUMS condition,
GR depleted-microglia showed reduced expression levels of pro-inflammatory genes
and increased neuroprotective as well as anti-inflammatory genes compared to WT-microglia.
Moreover, in microglial-GR depleted mice, but not in WT mice, CUMS led to a significant
reduction of CA1 long-term potentiation and paired-pulse ratio. Lastly, differences
in adult hippocampal neurogenesis were observed between the genotypes during normal
homeostatic conditions, with microglial-GR deficiency increasing the formation
of newborn neurons in the dentate gyrus subgranular zone independently from stress
exposure. Together, these findings indicate that, although the deletion of microglial
GR did not prevent the animal’s ability to respond to stress, it contributed to
modulating hippocampal functions in both standard and stressful conditions, notably
by shaping the microglial response to chronic stress.
