CELLULAR AND TRANSCRIPTOMIC BIOMARKERS IN AUTISM SPECTRUM DISORDER<\/span><\/strong><\/p>\n<p style=\"text-align: justify\"><span style=\"color: #000000;font-size: 12pt\">Autism spectrum disorder (ASD) affects 0.6% of the population which means 40 million people worldwide and 60.000 people in Hungary. Nevertheless, the pathomechamism of the condition is still unknown that is partly due to the lack of post mortem tissue available to research and the time consuming nature of the quantitative neurohistological investigations. There are no cellular biomarkers of ASD discovered which would provide objective diagnostic tools stratifying the condition.<\/span><\/p>\n<p style=\"text-align: justify\"><span style=\"color: #000000;font-size: 12pt\">In the Neuropsychiatry Research Group we investigate the post mortem human tissue with the combination of immunohistochemistry and transcriptomics. The morphometric and topografic analysis of various cell types in idigitized brain sections is carried out manually and with the help of \u2019machine learning\u2019 algorithms that make the detection of several million neurons possible. This approach allows the statistical analysis with an order of magnitude higher compared to classical neurohistological approaches.<\/span><\/p>\n<p style=\"text-align: justify\"><span style=\"color: #000000;font-size: 12pt\">Single nucleus RNA sequencing reveals cell populations and molecular mechanisms affected in ASD with unprecedented accuracy. This can be further augmented with information obtained by immunohistochemistry, reverse-transcriptase qPCR and in situ hybridization. With the help of animal models of ASD (such as the CNTNAP2-KO and SHANK3-KO mouse strains) we can reveal if the role of various neuronal populations found impaired in patients with ASD is conserved or acquired newly during primate brain evolution.<\/span><\/p>\n<p style=\"text-align: justify\"><span style=\"color: #000000;font-size: 12pt\">Mapping the local neuronal circuitry in the human prefrontal cortex is far from complete which impedes our understanding regarding the functional relevance of impaired neuronal subtypes in ASD. The role of cortical parvalbumin neurons in ASD has been highlighted by several studies and accepted by the neuroscience community. However, a recent single-cell study suggests cortical calretinin neurons being equally important in ASD pathology (Velmeshev et al., 2019). Remarkably, up to date there is no information on the afferent and efferent connections of calretinin neurons in the human prefrontal cortex. There is no data on the exact position of different calretinin neuronal subtypes in the local circuitry of the human prefrontal cortex, either. This knowledge is essential to fathom the effects of alterations within the calretinin populations and interpret them in context of behavioral manifestations of ASD.<\/span><\/p>\n<p style=\"padding-left: 40px\"><strong><span style=\"color: #232f61\">II. CELLULAR AND TRANSCRIPTOMIC BIOMARKERS IN SCHIZOPHRENIA<\/span><\/strong><\/p>\n<p style=\"text-align: justify\"><span style=\"color: #000000;font-size: 12pt\">Schizophrenia (SCH) is a heterogeneously manifesting condition, or more probably, a spectrum of conditions. With its prevalence estimated around 1%, it affects at least 75 million people worldwide and about 100.000 people in Hungary. Some 110 years after Eugen Bleuler coined the term \u2018schizophrenia\u2019 in psychiatry, the cause of the disorder still remains a question: the exact neuropathological mechanisms driving its characteristic symptoms are largely unknown. Although a large number of intriguing genetic and transcriptomic disturbances have been revealed in multiple brain regions evidently affected in SCH, we are still far from understanding the whole picture. As of today, no validated biomarkers are available for the objective diagnosis of schizophrenia.<\/span><\/p>\n<p style=\"text-align: justify\"><span style=\"color: #000000;font-size: 12pt\">Detecting and annotating certain types of brain cells with classic, manual neurohistological methods can be extremely time-consuming. Today, it is possible to scan whole tissue sections with slide scanners, allowing for faster, easier digital image analysis. This technology makes it possible to process several cm2 of tissue, in contrast to the square millimetres analysed by researchers limited by technology a few decades ago. Furthermore, it enables incorporating artificial intelligence into neurohistology as well: currently we are in collaboration with Istvan Csabai (ELTE) and his coworkers to train neural networks to detect cells.<\/span><\/p>\n<p style=\"text-align: justify\"><span style=\"color: #000000;font-size: 12pt\">In the field of \u2018omics\u2019, transcriptomics focuses on RNA molecules, with special interest to mRNA molecules (which carry genetic information from DNA to the sight of protein translation). Recent technical advances made it possible to investigate RNA molecules at the level of individual cells or nuclei (single cell\/nucleus RNA sequencing). With the bioinformatical analysis of gene expression patterns, one can identify known cell types and discover new ones. Further analysis can reveal their developmental ontology and inform about the functional relevance of specific cell types. For comparing samples from diseased and healthy tissue, single cell techniques are currently the most precise and diversely informative methods to detect cell type specific alterations.<\/span><\/p>\n<p style=\"text-align: justify\"><span style=\"color: #000000;font-size: 12pt\">As of today, single cell techniques are the most elaborate and diversely informative methods when it comes to detecting alterations in diseased tissue.<\/span><\/p>\n<p style=\"text-align: justify\"><span style=\"color: #000000;font-size: 12pt\">So far, neurohistological studies rarely applied a holistic approach, because it is challenging, expensive and time-consuming to investigate different biological levels (DNA, mRNA, protein, and the whole cell) within the same tissue at the same time. Researchers are also rarely able to individually correlate results with detailed medical history \u2013 for this, well-documented, accessible clinical information is essential. Only in light of individual heterogeneity can we begin to understand the heterogeneity of SCH and the pathological mechanisms causing it. Such approach is inevitable in order to establish a neurochemical foundation for personalized psychiatric care.<\/span><\/p>\n<p style=\"text-align: justify\"><span style=\"color: #000000;font-size: 12pt\">Studying the potential mechanisms of schizophrenia, we found that results from different biological levels point to the same direction: the most affected cell types seem to be interneurons residing in the upper cortical layers (most prominently somatostatin, parvalbumin and calretinin expressing neurons) and CUX2-expressing excitatory neurons. Investigating which physiological functions and signaling pathways are associated with the differently expressed genes, we found that genes upregulated in SCH played a role in synaptic transmission and certain neurodevelopmental processes, while downregulated genes were associated to mitochondrial functioning, energy metabolism and protein production-related processes. These results suggests that while synaptic transmission is altered, neuronal energy metabolism is disrupted in SCH. Furthermore, we defined two putative cellular phenotypes of SCH based on interneuronal densities in the dorsolateral prefrontal cortex.<\/span><\/p>\n<p style=\"padding-left: 40px\"><strong><span style=\"color: #232f61\">III. TRENDS OF ASTROGLIAL AND INTERNEURON HETEROGENITY IN THE EVOLUTION OF PRIMATES<\/span><\/strong><\/p>\n<p style=\"text-align: justify\"><span style=\"color: #000000;font-size: 12pt\">As Dobzhansky stated: \u201enothing in biology makes sense, unless viewed in the light of evolution\u201d \u2013 the human brain can only be understood in light of the primate brain. The most vulnerable elements within the brain network (e.g., cell types or receptor subtypes) are most probably the newly evolved ones. The excitatory\/inhibitory balance is generally thought to be disrupted in neuropsychiatric disorders. Our results indicate that upper-layer neurons might play a crucial role in this imbalance. The upper cortical layer is also thought to be a so-called \u201cevolutionary hotspot\u201d: here, relative interneuronal density increased selectively (calretinin neurons) during mammalian evolution, and neuronal cell types diversified, a process most probably accompanied by functional specialization. More cells and more functions mean more options, but could also possibly mean more potential errors. Hypothetically, neuropsychiatric disorders such as schizophrenia and autism spectrum disorder could be the \u201cside product\u201d of evolution. To investigate evolutionary questions, we established the Primate Brain Collection in 2016 with Endre So\u00f3s, head veterinarian of the Budapest Zoo. In the following years, the Ny\u00edregyh\u00e1zi \u00c1llatpark (S\u00f3st\u00f3 Zoo; Alexandra Bi\u00e1csi) and the Veszpr\u00e9m Zoo (P\u00e9ter T\u00f3th-Alm\u00e1si) also joined the project. We transport, dissect and fix the brains of naturally perished animals within the shortest possible time. Today, the collection consists of more than 40 cases across13 species. The main taxonomic groups are all represented (New and Old World monkeys, Lemuriformes). Our short-term aim is to reach a sample number of n=3, which will allow for basic statistical analysis of our quantitative results. The Primate Brain Collection is open for Hungarian and international researchers: anybody can apply for samples with a thorough, relevant research plan.<\/span><\/p>\n<p><strong><span style=\"color:
