A major focus of my research is to study the role for spatial genome organization and nuclear architecture in aspects of neuronal function associated with memory consolidation and cognition. We are employing mouse genetic models of the chromosomal architectural protein SATB2 and a combination of biochemical, cell biological methods, and high-throughput next-generation sequencing to understand how alterations in chromatin looping and/or tethering of chromatin to the nuclear lamina can orchestrate programs of gene expression that underlie long-term neuronal plasticity. We are also using behavior analyses in loss-of-function models to uncover the functional significance of 3D genome topology and nuclear lamina-directed genome organization for adaptation to novel environments, learning behaviors and memory formation.

In humans, rare de novo alterations in SATB2 locus cause a syndrome characterized by developmental delay and severe intellectual disability, whereas common variation is linked to general intelligence and risk for schizophrenia. In collaboration with D. Morris (National University of Ireland), we recently demonstrated that the genes regulated by SATB2 as well as the genes encoding SATB2 interacting proteins are highly constrained. Rare high impact mutations in these genes cause severe cognitive disorders whereas common low impact variants influence cognitive ability in the general population and contribute to schizophrenia and educational attainment. Our long term goal is to gain deeper insights into SATB2 molecular functions in the brain and to understand how defects in the chromatin loop establishing/stabilizing machinery in the neuronal cell nucleus could lead to cognitive dysfunction and memory impairments.

We believe that differentiated postmitotic neurons in order to sustain the demands for lifelong performance and respond to varied environmental stimuli with long-lasting changes in structure and physiology are equipped with specialized mechanisms to reconfigure their 3D genome on a large scale and in a dynamic fashion. Our long-term goal is by studying these mechanisms to facilitate the discovery of novel intranuclear drug targets for treatment of cognitive impairment and mental illness.

Courses offered for the PhD/master students at the Medical University of Innsbruck:

Nico Wahl, PhD

Role:      Postdoctoral Researcher
Email:    Nico.Wahl@i-med.ac.at

Nico is interested in higher order chromatin organization and the epigenetic mechanisms underlying memory formation. In his research he focuses on cortical excitatory neurons, genotype differences and activity dependent mechanisms. His aim is to identify novel targets of known intelligence associated regulatory elements.

Nico joined the Dechant lab in October 2017 and is part of the SPIN Neuroscience excellence program. He obtained his M.Sc. at the Management Center Innsbruck and wrote his Master Thesis at the Rockefeller University, New York in the laboratory of Tom Tuschl. There he first gained insight into transcriptomic research and helped establish the 10xGenomics single cell RNA sequencing platform. At the end of 2018 he went to Mount Sinai, New York to work with Schahram Akbarian, M.D., PhD. and Kristen Brennand, PhD. to learn novel techniques to study chromatin dynamics and how to derive excitatory neurons form human induced pluripotent stem cells (iPSCs). When not in lab Nico enjoys to meet friends and skiing in the Alps.

Mujahid Ali, PhD
Role:   Postdoctoral Researcher
Email: Mujahid.Ali@i-med.ac.at

Ali is interested in studying 3D chromatin organization and epigenetic mechanisms associated with learning and memory in response to the turnover of molecular targets in the hippocampus. He aims to uncover the regulatory role of novel molecules in the pyramidal neurons involved in learning, particularly in the context of early life stress and its long-lasting effect on gene regulation and social behavior.

He completed a joint Master's degree from IMC Krems in Austria and the University of Cambridge in England. During his Master's studies, he studied the transcriptome of resistance and susceptible genes in response to Nora and IIV6 viruses in DGRP lines. This experience provided him with a strong foundation in molecular biology and genomics. Continuing his academic journey, in 2016, he joined the doctoral program in the Zhou lab at the Department of Neurosciences, University of Vienna. In his Ph.D., he studied the epigenomic chromatin landscapes and 3D genome organization during the development of Drosophila. This work allowed him to develop expertise in analyzing high-throughput sequencing data, utilizing cutting-edge techniques, and unraveling the intricate relationship between epigenetics and genome architecture, which drove him a curiosity for understanding the molecular underpinnings of neurodevelopment of spatial learning and memory.

Paola Chietera, M.Sc.

Role:   PhD Student
Email: Paola.Chietera@i-med.ac.at

Paola started her PhD in the Institute for Neuroscience in November 2020 under under Prof. Apostolova’s supervision. Her current project focuses on the nuclear lamina (NL), a meshwork of type-A and –B lamins, which is anchored to the inner part of the nuclear envelope via interactions with inner nuclear membrane (INM) proteins. Paola investigates the role of chromatin-NL interactions and INM proteins in mouse excitatory cortical neurons and their influence on gene expression, spatial genome organization and synaptic plasticity.

Before joining the lab, she absolved her Bachelor degree in Biotechnology at the Management Center Innsbruck (MCI), obtained her Master degree in Molecular Medicine at the Medical University of Innsbruck (MUI) and wrote her Master thesis at the Department of Pharmacology in Prof. Ferraguti´s lab. There, she focused her work on the contribution of mGlu5 receptors in different subfields of the mouse ventral hippocampus to the manifestation of anxiety-like behaviour. In particular, she helped establishing a computational approach for the objective quantification of the extent of mGluR5 ablation and its correlation with the behavioural phenotype. During her stay, she gained experience in behavioural test paradigms and molecular biology techniques.

AdriáGonzález Díaz, M.Sc.
Role:   PhD Student
Email: Adrian.Gonzalez@i-med.ac.at

Adrián hold a Bachelor’s degree in Biology and a Master’s degree in Neuroscience at the Autonomous University of Barcelona. He was involved in a project studying DYRK1A-mediated functions in intellectual disability syndromes. Moreover, he conducted his Master’s thesis assessing the potentiation and recovery of memory by ICSS in rats with and without brain damage. Hence, he is keenly interested in the neurobiological impact of genetic risk loci related to cognitive functions and dysfunctions.
Adrián is part of the Institute for Neuroscience since he started his PhD in October 2023 under the supervision of Ass. Prof. Apostolova. He is currently using differentiated human pyramidal neurons form hiPSCs to uncover SATB2 effects on multiple genomic modalities, and allowing direct comparison between human and mouse data. In essence, he investigates SATB2 link to neuropsychiatric diseases and its role in higher cognitive ability in humans.
When he is not working, Adrián likes to cook, hike in the Alps or have a drink with some friends.
