Neuropsychiatric disorders are frequently inherited, and in many cases result from spontaneous mutations. Studies with patients have identified many defects in the genes for proteins that play key roles in fast neurotransmission and in brain development, in particular proteins found in excitatory neurons. These are, on the one hand, ion channels activated by the neurotransmitter glutamate and, on the other hand, scaffolding proteins that organize the topographic arrangement and intracellular signaling cascades in response to activation of these ion channels. The latter thus determine the efficiency and the quality of the glutamatergic signal transmission. Our research aims to identify gene markers for diagnostic purposes and to understand the consequences of the defect as a basis for therapeutic approaches. Our focus is on defects associated with schizophrenia, cognition problems and autism. We generate and analyze numerous genetically manipulated mouse models with abnormal cognitive and social behaviors, and try to rescue behavioral impairments by drug treatment. Our genetically or virally manipulated mice have been shown to provide reliable and useful models of schizophrenia and depression. Other mouse lines were more suitable for the analysis of physiological mechanisms underlying short and long-term memory. Over-expression of the structural protein SHANK2 allowed us to show that genetically-related ASD-like behavior in mice can be cured by repairing the gene defect in adult mice.(Barkus, C., et al. Neuropharmacology 62, 1263-1272 (2012); Fitzgerald, P.J., et al. Neurobiol. Dis. 40, 608-621 (2010); Inta, D., et al. Neurosci. Biobehav. Rev. 34, 285-294 (2010); Sanderson, D.J., et al. Prog.

Neuroscience 26, 8428-8440 (2006); Zamanillo, D., et al. Science 284, 1805-1811 (1999)).

The role of the glutamate-gated ion channels and the postsynaptic organizer: SHANK2 in schizophrenia, cognition and autism/attention deficits
Two types of glutamate receptors have been known for many years. The form that is activated by AMPA was recognized as an essential glutamate-gated ion channel involved in synaptic transmission. In 1999 we showed that it is also involved in memory formation. In our recent work we have solidified our 20 year-old hypothesis (Zamanillo, D., et al. Science 284, 1805-1811 (1999); Reisel, D. et al., Nat. Neurosci. 5(9), 868-873 (2002)) that AMPARs with the GluA1 subunit are essential for short-term memory, also called working memory, but are not required for learning complex associations (Bannerman et al., 2018; Shimshek et al., 2017). The loss of GluA1-containing AMPARs in a few brain regions was sufficient to impair working memory, and the genetic repair of GluA1 AMPARs in the hippocampus of GluA1 knock-out animals was sufficient to partially restore short-term memory. From this we could also conclude that several brain regions cooperate in a good short-term memory (Freudenberg et al., 2016). In a very recent study, we were able to show directly that the communication between prefrontal cortex and hippocampus, measured in oscillations, is disturbed in animals with poor short-term memory, and this is precisely when this memory is needed to make a correct decision (Bygrave et al., 2019). This allowed us to establish a direct link between schizophrenia, lack of short-term memory and the risk gene GluA1 for bipolar disorders, as we had postulated in our previous work (Weber et al., 2015; Inta et al., 2014; Vogt et al., 2014; Boerner et al., 2017; Sanderson et al., 2017) and as is supported by the poor short-term memory of schizophrenic patients. More importantly, we could attenuate the hyperactivity of our GluA1 deficient mice by haloperidol and cannabidiol (Boerner et al., 2017, Aitta-Aho et al., 2019), both of which are possible candidates for treatment of schizophrenia. In contrast to GluA1 deficient mice, gene-targeted mice which lack an important AMPAR trafficking protein (FRRS1l) showed severe behavioral and learning impairments similar to the handicaps in a young human patient with FRRS1l deficiency (Schwenk et al. 2019).

The N-methyl-D-aspartate receptors (NMDARs)
By contrast, glutamate receptors which are also activated by NMDA were recognized early on as being involved in controlling the formation and the modulation of neuronal networks: the regulated Ca2+ influx through them triggers cellular mechanisms closely associated with learning and memory. In our recent studies we observed neuropsychiatric defects in mice after  cell-type-specific NMDAR knock-out pharmacological NMDAR inhibition (Lang et al., 2018; Bygrave et al., 2016), in line with reports on the behavioral alterations in NMDAR hypomorphic mice and with NMDAR point mutations in patients with variable neurological phenotypes (Mohn et al., Cell 98, 427-436  (1999); Endele, S et al., Nat Genet 42, 1021–1026(2010)). In one patient with cognitive impairments and epileptic seizures, the mutation GluN2A(N615K) inhibited the precise NMDARs-guided Ca2+ influx. The analysis of our mice with the analogous mutation GluN2A(N615S) provided first experimental evidence that muscular hypotonia, audiogenic induced seizures (AGS), pronounced hyperactivity, reduced social interaction and selective inability to learn complex spatial associations are directly linked to the GluN2A(N615S) mutation and its inaccurate Ca2+ signaling (Bertocchi et al., 2019, in preperation). We could rescue hyperactivity by amphetamine and by memantine AGS, indicating the acute involvement of disturbed NMDAR signaling in the neurological phenotype (Figure 1). In summary, the global expression of GluN2A(N615S) unravelled several neuronal networks in the forebrain and the brainstem, which are using precise activity-dependent NMDAR Ca2+ signalling to balance conflicting information between functionally connected neuronal networks. In two reviews we discussed our view of the role of NMDARs in the hippocampus in spatial learning (Bannerman et al., 2014; Taylor et al., 2014).

SH3 and multiple ankyrin repeat domain proteins (SHANKs)
Mutations in the three SHANK genes have frequently been identified in patients with Autism Spectrum Disorders (ASD). The huge spectrum of behavioral abnormalities, ranging from schizophrenia to autism or the Asperger syndrome associated with mutations, is reminiscent of the high diversity of phenotypes of 29 SHANK knock-out mouse lines (Eltokhi et al., 2018). Furthermore, we showed that the sex hormones result in strong gender-dependent differences in the expression of Shank genes (Berkel et al., 2018). Using strong and conditional overexpression of the SHANK2A and the SHANK(R462X) truncation in excitatory forebrain neurons during and after development (Figure 2) we found that the social component of the ASD-like behaviour could be erased when we switched off the SHANK2A overexpression in adult mice, demonstrating that the social component of ASD can be restored by therapeutic treatment but not other components such  as hyperactivity, anxiety and cognitive dysfunctions. In both lines the hyperactivity could be attenuated by amphetamine, indicating an increase activity of the glutamatergic system (Eltokhi et al., 2019, in preperation).

Development of virus-mediated gene transfer in the mouse brain
We developed viral vectors for tagging specific neuron and astroglia populations with genetic fluorescence or activity indicators or optical and pharmacological silencers. We provided proof of the long-term expression of virus-delivered secreted peptide hormones in the brain, provided a system for pharmacological long-term silencing of neuronal populations, and evaluated the interaction of different brain regions during the formation and expression of fear (Hasan et al, 2019, Dogbevia et al., 2016; Heinonen et al., 2014; Schwarz et al., 2015; Lissek et al., 2016; Obenhaus et al.,2016; Eliava et al.,2016). We used genetic activity indicators to analyse the kinetics of astrocyte activity in vitro and visualized in vivo the temporal relationship between the cortical spread of glutamate, neuronal and glial activity in an animal model of migraine (Heuser et al., 2018; Enger et al., 2017; Enger et al., 2015; Tang et al., 2015, Enger et al., 2019).

Within the next two years I will complete my research under the collaboration agreement between the Heidelberg University Hospital and the MPImR. Externally funded projects with the Central Institute of Medical Health (CIMH) in Mannheim and the University of Oslo will be continued until June 2021.
