Title:
Characterization of Gprasp2 knockout mice as a new model for autism spectrum disorders
Publication year: 2017
Abstract/Results:
ABSTRACT:
Spectrum Disorders (ASD) and Intellectual Disability (ID) are neurodevelopmental disorders that share common aspects in genetic etiology and phenotypic presentation. Nevertheless, despite a significant number of studies the exact mechanisms triggering these neurodevelopmental disorders and the neuronal circuits disrupted are not completely understood. A recent hypothesis has implicated deficits in synaptic plasticity and spine structure on behavioral and cognitive alterations in patients.
G-protein coupled receptors (GPCRs) are known for their role in the regulation of synaptic signaling. Some of the members of this broad family, include the metabotropic glutamate receptor family (mGluR) which are known for their role in synaptic plasticity and in the mediation of long-term depression. Both these mechanisms have been shown to be deregulated in various neuropsychiatric and neurodevelopmental disorders. Additionally, the regulation and trafficking of mGluRs as well as their intracellular partners have been gaining increased attention. In line with this, the G-protein coupled receptor associated sorting protein (Gprasp) family is an interesting target since Gprasp2 has been implicated in psychiatric disorders. Gprasp2 is also a pleiotropic susceptibility candidate gene implicated in autism and is thought to be involved in the endocytic sorting of G-protein coupled receptors.
To understand the role of Gprasp2 in vivo, a Gprasp2 KO model was recently developed. Here we explore the characterization of this animal model at a behavioral and neuronal morphology level. In our behavioral characterization, we found deficits in terms of memory and cognition in Gprasp2 KO mice pointing towards a defect in terms of hippocampal function. Aligned with these results, decreased dendritic complexity and decreased number of mature spines was also found in the CA1 region of the hippocampus. Changes in mRNA levels were also found in the hippocampus that pointed towards a synaptic signaling deficiency. We also found an increase in body weight and changes in behaviors connected to social dominance and aggression in Gprasp2 KO mice, suggesting a role for this gene in hypothalamic circuit function.
Our data suggest that Gprasp2 mutations may contribute to the pathogenesis of neurodevelopmental disorders, affecting hippocampal dendritic and spine morphology and hippocampal and hypothalamic-mediated behaviors. The Gprasp2 KO mice display deficits consistent with ASD and ID-like behaviors.

The role of cortico-striatal projections in social hierarchies
Publication year: 2017
Abstract/Results:
ABSTRACT:
In nature, animals in a group will engage in competition for dominance, leading to the formation of a hierarchy. A social hierarchy allows some individuals (of higher rank) to gain priority in accessing food, mate selection and resting places, reducing both the number and intensity of conflicts. Recent neuroimaging studies have begun to elucidate the neurobiological underpinnings of social hierarchy formation, by identifying and characterizing key brain regions involved in behavior repertoire. Furthermore, cortical projections between the mPFC (medial PFC) and Nucleus Accumbens (NAc) have been widely described to guide mice behaviour during non-social and, more recently, during social contexts. However, little is known about their role in social dominance behaviour.
In the course of this work, we found evidence that suggest that these two regions may encode winning information in the tube test setting. Furthermore, we were able to disrupt an already established social hierarchy by optogenetically activating corticostriatal projections, making the subordinate become dominant. Furthermore, we also found evidence that suggest that this change in rank can induce a “winner effect” in the stimulated mouse, winning trials even when not stimulated. However, this change was not long lasting, with the stimulated mouse returning to its initial rank after only a few days. Taken all into account, we provide further insight into the role of these projections and their involvement in social dominance behaviour.

Abnormal mGluR-mediated synaptic plasticity and autism-like behaviours in Gprasp2 mutant mice
Publication year: 2019

https://www.nature.com/articles/s41467-019-09382-9
Abstract/Results: ABSTRACT:
Autism spectrum disorder (ASD) is characterized by dysfunction in social interactions, stereotypical behaviours and high co-morbidity with intellectual disability. A variety of syndromic and non-syndromic neurodevelopmental disorders have been connected to alterations in metabotropic glutamate receptor (mGluR) signalling. These receptors contribute to synaptic plasticity, spine maturation and circuit development. Here, we investigate the physiological role of Gprasp2, a gene linked to neurodevelopmental disabilities and involved in the postendocytic sorting of G-protein-coupled receptors. We show that Gprasp2 deletion leads to ASD-like behaviour in mice and alterations in synaptic communication. Manipulating the levels of Gprasp2 bidirectionally modulates the surface availability of mGluR5 and produces alterations in dendritic complexity, spine density and synaptic maturation. Loss of Gprasp2 leads to enhanced hippocampal long-term depression, consistent with facilitated mGluR-dependent activation. These findings demonstrate a role for Gprasp2 in glutamatergic synapses and suggest a possible mechanism by which this gene is linked to neurodevelopmental diseases.

Abstract/Results: ABSTRACT:
Prolonged exposure to stressful conditions in early life imparts changes to physiology and health and may trigger or exacerbate neuropsychiatric disorders. Overt dysfunction in sociability is also a hallmark of disorders such as autism spectrum disorder (ASD) and schizophrenia. Likewise, abnormal social interaction in otherwise healthy individuals is itself a trigger for mental health disorders. In addition, for most social animals, the relative position an individual occupies in its social hierarchy strongly modulates psychosocial stress.
Early life stress (ELS) induced by maternal separation is acknowledged to have long-term effects on animal behavior and is considered one of the most potent, naturally-occurring stressors. In humans, childhood adversity, neglect or mistreatment is known to increase the risk for psychiatric disorders, including depression and anxiety. In rodent models of maternal separation, behavioral deficits are observed in emotional behavior and stress responses. At the same time, neurological dysfunctions have been identified in both humans and mice exposed to ELS. However, the precise neuronal substrates and mechanisms that traduce ELS into altered neuronal activity and subsequent social dysfunction in adulthood are poorly understood. While the role of stress impacting adult animals and promoting changes to social behavior and social hierarchies is well described, the influence of ELS on adult social hierarchical rank and social behaviors remains largely unknown. Our results uncovered that ELS induces a dysfunction in social hierarchy and social interactions in mice. We observed that ELS mice display a lower social rank when compared to control animals and are more easily defeated in dominant-subordinate competitions. ELS also led to long-lasting functional alterations in the medial prefrontal cortex (mPFC), as evidenced by an increased c-fos expression in response to social dominance stimuli.
Additionally, neuronal atrophy and increased inhibitory synaptic strength were observed in mPFC neurons from adult mice that experience ELS. In terms of gene expression in the mPFC, we found that the mRNA of Npy1r was upregulated in ELS mice and also in wild-type subordinate animals, suggesting a role for this gene in behaviors regulating social dominance.
Together, our data suggests that ELS leads to long-lasting alterations in gene expression and to altered mPFC activity, inducing a subordinate behavior within a social hierarchy. Lastly, we proposed Npy1r signaling as a key modulator of social rank and a potential therapeutic target for social dysfunctions.

Abstract/Results: ABSTRACT:
Social hierarchies are present in most mammalian species. In nature, hierarchies offer a tradeoff between reduction of in-group fighting between males, at the expense of an asymmetric sharing of resources. Early life experiences and stress are known to influence the rank an individual attains in adulthood, but the associated cellular and synaptic alterations are poorly understood. Using a maternal separation protocol, we show that care-deprived mice display a long-lasting submissive phenotype, increased social recognition, and enhanced explorative behavior. These alterations are consistent with an adaptation that favors exploration rather than confrontation within a group setting. At the neuronal level, these animals display dendritic atrophy and enhanced inhibitory synaptic inputs in medial prefrontal cortex (mPFC) neurons. To determine what could underlie this synaptic modification, we first assessed global gene expression changes via RNAseq, and next focused on a smaller subset of putatively altered synaptic receptors that could explain the changes in synaptic inhibition. Using different cohorts of maternally deprived mice, we validated a significant increase in the expression of Npy1r, a receptor known to play a role in maternal care, anxiety, foraging, and regulation of group behavior. Using electrophysiological recordings in adult mice while blocking NPY1R signaling, we determined that this receptor plays a key role in enhancing GABAergic currents in mice that experience maternal deprivation. Taken together, our work highlights the potential of regulating NPY1R in social anxiety disorders and the alterations induced in brain circuitry as a consequence of early life stress and adversity.

Abstract/Results: ABSTRACT:
BACKGROUND
Social behaviors are critical to the survival of most animal species. Gregarious behaviors strengthen social groups, reduce stress and increase fitness. However, the genetic and circuit basis of the regulation of social behaviors are not well understood.
AIMS
We aimed to dissect the influence of specific genes in social behaviors and their influence in neuronal circuits. One part of our project aimed at discovering, in an unbiased manner, which genetic elements could regulate social subordinance when animals experience early life stress. A second project investigated the role of GPRASP2, a gene known to influence sociability and autism in humans, in order to best understand its role in the brain.
METHOD
To dissect which genetic elements are responsible to induce social subordination following early life stress, we used a maternal deprivation protocol in C57BL6 mice. We also used a genetically engineered mouse model to understand the role of GPRASP2 in the regulation of social behaviors. For both approaches we employed a range of behavioral, histological and electrophysiological characterization.
RESULTS
This work sheds light on ethologically relevant processes with impact on biomedical sciences. Specifically, we found that the NPYergic system is important in the regulation of cortical circuits and the expression of social subordinate behavior. We also found that loss of GPRASP2 leads to altered social behaviors, deficits in social recognition and increased dominate behavior.
CONCLUSIONS
Our work identified novel genetic elements that play a significant role in the regulation of social behaviors.

Aberrant hippocampal transmission and behavior in mice with a stargazin mutation linked to intellectual disability
Publication year: 2022

https://www.nature.com/articles/s41380-022-01487-w
Abstract/Results: Mutations linked to neurodevelopmental disorders, such as intellectual disability (ID), are frequently found in genes that encode for proteins of the excitatory synapse. Transmembrane AMPA receptor regulatory proteins (TARPs) are AMPA receptor auxiliary proteins that regulate crucial aspects of receptor function. Here, we investigate a mutant form of the TARP family member stargazin, described in an ID patient. Molecular dynamics analyses predicted that the ID-associated stargazin variant, V143L, weakens the overall interface of the AMPAR:stargazin complex and impairs the stability of the complex. Knock-in mice harboring the V143L stargazin mutation manifest cognitive and social deficits and hippocampal synaptic transmission defects, resembling phenotypes displayed by ID patients. In the hippocampus of stargazin V143L mice, CA1 neurons show impaired spine maturation, abnormal synaptic transmission and long-term potentiation specifically in basal dendrites, and synaptic ultrastructural alterations. These data suggest a causal role for mutated stargazin in the pathogenesis of ID and unveil a new role for stargazin in the development and function of hippocampal synapses.

Abstract/Results: Social status is recognized as a major determinant of social behavior and health among animals; however, the neural circuits supporting the formation and navigation of social hierarchies remain under extensive research. Available evidence suggests the prefrontal cortex is a keystone in this circuit, but upstream and downstream candidates are progressively emerging. In this review, we compare and integrate findings from rodent and primate studies to create a model of the neural and cellular networks supporting social hierarchies, both from a macro (i.e., circuits) to a micro-scale perspective (microcircuits and synapses). We start by summarizing the literature on the prefrontal cortex and other relevant brain regions to expand the current “prefrontal-centric” view of social hierarchy behaviors. Based on connectivity data we also discuss candidate regions that might inspire further investigation, as well as the caveats and strategies that have been used to further our understanding of the biological substrates underpinning social hierarchy and dominance.

Abstract/Results: Abstract
Spatial control of gene expression is critical to modulate cellular functions and deconstruct the function of individual genes in biological processes. Light-responsive gene-editing formulations have been recently developed; however, they have shown limited applicability in vivo due to poor tissue penetration, limited cellular transfection and the difficulty in evaluating the activity of the edited cells. Here, we report a formulation composed of upconversion nanoparticles conjugated with Cre recombinase enzyme through a photocleavable linker, and a lysosomotropic agent that facilitates endolysosomal escape. This formulation allows in vitro spatial control in gene editing after activation with near-infrared light. We further demonstrate the potential of this formulation in vivo through three different paradigms: (i) gene editing in neurogenic niches, (ii) gene editing in the ventral tegmental area to facilitate monitoring of edited cells by precise optogenetic control of reward and reinforcement, and (iii) gene editing in a localized brain region via a noninvasive administration route (i.e., intranasal).

BIAL Foundation Archive
Start date: 1994
History:
The BIAL Foundation was created in 1994 by Laboratórios BIAL in conjunction with the Council of Rectors of Portuguese Universities. BIAL’s Foundation mission is to foster the scientific study of Man from both the physical and spiritual perspectives.
Along the years the BIAL Foundation has developed an important relationship with the scientific community, first in Portugal and after worldwide. Today it is an institution of reference which aims to stimulate new researches that may help people, promote more health and contribute to new milestones to gain access to knowledge.
Among its activities the BIAL Foundation manages the BIAL Award, created in 1984, one of the most important awards in the Health field in Europe. The BIAL Award rewards both the basic and the clinical research distinguishing works of major impact in medical research.
The BIAL Foundation also assigns Scientific Research Scholarships for the study of neurophysiological and mental health in people, arousing the interest of researchers in the areas of Psychophysiology and Parapsychology.
To date the BIAL Foundation has supported 461 projects, more than 1000 researchers, with research groups in twenty-seven countries, resulting, until April 2013, in about 600 full papers, out of which 172 published in indexed international journals with an average impact factor of 3.6 and a substantial number of citations (1665).
Since 1996 the BIAL Foundation organizes the Symposia entitled "Behind and Beyond the Brain", a Forum that gathers well renowned neurosciences speakers and the BIAL Foundation Fellows which are spread around the world.
Classified as an institution of public utility, the BIAL Foundation includes among its patrons the Portuguese President, the Portuguese Universities Rectors' Council and the Portuguese Medical Association.

Title: BIAL Grants
Start date: 1994
History:
In 1994 the BIAL Foundation launched a programme of science research grants with the aim of encouraging the research into Man’s physical and mental processes, namely in fields still largely unexplored but which warrant further scientific analysis, as Psychophysiology and Parapsychology.
Since its launch, applications to the BIAL grants have been increasing. Up to now 461 projects have been supported, involving more than 1000 researchers from 27 countries.
The approved applications have benefited from grants in amounts comprised between €5,000 and €50, 000. The amount to be granted is fixed by the Scientific board according to the needs of each project.
The supported projects have originated, until April 2013, in about 600 full papers, 172 out of which were published in indexed international journals with an average impact factor of 3.6 and a substantial number of citations (1665).
Among the BIAL Foundation fellows is worth highlighting the presence of scientists from prestigious universities from the United States, United Kingdom, Australia, Russia, Germany, Japan, France, Canada, and many others.
The BIAL grants are promoted biannually.

Title:
Microglia-dependent remodeling of neuronal circuits
Publication year: 2022

Abstract/Results: Abstract
Microglia are tissue-resident macrophages responsible for the surveillance, neuronal support, and immune defense of the brain parenchyma. Recently, the role played by microglia in the formation and function of neuronal circuits has garnered substantial attention. During development, microglia have been shown to engulf neuronal precursors and participate in pruning mechanisms while, in the mature brain, they influence synaptic signaling, provide trophic support and shape synaptic plasticity. Recently, studies have unveiled different microglial characteristics associated with specific brain regions. This emerging view suggests that the maturation and function of distinct neuronal circuits may be potentially associated with the molecular identity microglia adopts across the brain. Here, we review and summarize the known role of these cells in the thalamus, hippocampus, cortex, and cerebellum. We focus on in vivo studies to highlight the characteristics of microglia that may be important in the remodeling of these neuronal circuits and in relation to neurodevelopmental and neuropsychiatric disorders.
