The international day of 22q11.2 deletion syndrome

22q11.2 deletion syndrome (22q11.2DS) is a disorder caused by a heterozygous microdeletion of region q11.2 of chromosome 22. It is the most common microdeletion syndrome in humans with an estimated incidence of approximately 1/4000 per live births. The spectrum of clinical manifestations in patients with this syndrome is very variable, even within the same family. Approximately, 25% of patients with 22q11.2DS develop schizophrenia. Intellectual disability is detected in approximately 45% of patients with 22q11.2DS, while ASD is seen in 14-50% of cases. STREAMLINE research project aims to study molecular mechanisms underlying intrafamilial phenotypic variability in patients with 22q11.2DS.

November 22nd, is the international day of 22q11.2 deletion syndrome. STREAMLINE team marked this day by wearing red.

The first staff exchange successfully finished

Our first staff exchange was successfully finished. The members of the STREAMLINE team, dr Danijela Drakulic and dr Natasa Kovacevic Grujicic spent three months at Cardiff University, United Kingdom to receive hands-on training on cell reprogramming of the somatic cells. They came back full of impressions and ready to introduce a new methodology in our institute.

The presentation of STREAMLINE at the event “European Researcher’s Night 2022”

Under the slogan: “Streets under the lights of science” on 30.09. 2022 and on 01.10. 2022, the 13th European Researchers’ Night was held in Belgrade. The main goal of the event was to raise public awareness of the importance and positive role of science for society by putting the researcher in the focus of public. This was an opportunity to promote STREAMLINE among general public. Within the session: “Fascination by innovation” Academician Milena Stevanović gave a lecture entitled: “The brain in a petri dish: The STREAMLINE project and innovative approaches for disease modeling.”

The brain in a petri dish: The STREAMLINE project and innovative approaches for disease modeling

Neurodevelopmental disorders (NDDs) are caused by alterations in early brain development and for their research, cutting-edge technology must be applied. The STREAMLINE project allows researchers to use the newest state-of-the-art technology for neurodevelopmental disorders based on the use of stem cells and brain organoids. These innovative technologies will improve our understanding of the processes involved in brain development and advance our understanding of brain disorders. The project will contribute to the discovery of molecular mechanisms underlying neurodevelopmental disorders as well as the development of novel potential therapeutics and their testing on these stem cell-based model systems.

Stem cell-based systems for modelling human diseases in patient-specific genetic background

Induced pluripotent stem cells (iPSCs) are reprogrammed from human somatic cells through ectopic expression of various transcription factors. The iPSC technology was pioneered by Shinya Yamanaka’s laboratory in Kyoto, Japan. This breakthrough scientific achievement won the Nobel Prize in Physiology or Medicine in 2012 “for the discovery that mature cells can be reprogrammed to become pluripotent”.

iPSCs derive from skin or blood cells that have been reprogrammed back into an embryonic-like pluripotent state, which, in turn, can differentiate into different types of cells within the body, representing an unlimited source of any type of human cell needed for research or therapeutic purposes. The ever-improving technology to generate iPSCs has increased their applicative potential including disease modeling, drug testing and toxicology screening as well as regenerative medicine and cell therapy.

STREAMLINE goal is to raise the quality of research and innovation of the Institute of Molecular Genetics and Genetic Engineering (IMGGE), University of Belgrade by introducing novel stem cell-based systems for modelling human diseases in patient-specific genetic background and by acquiring cutting-edge technology in generating brain organoids, unique 3D model systems that will provide further progress in understanding brain development and brain pathologies.

Dr. Danijela Drakulić and Dr. Nataša Kovačević Grujičić, associates of the Laboratory for Human Molecular Genetics, IMGGE, University of Belgrade, picked the first colonies of iPSCs derived from patients with familial form of the 22q11.2 deletion syndrome during staff exchange at Cardiff University as part of the exploratory research project within STREAMLINE. The obtain iPSCs will be further differentiated into neuronal and astroglial cells.  This stem cell-based systems for modelling human diseases combined with the generation of brain organoids provide an opportunity to recapitulate both normal and pathologic human tissue formation in vitro, enabling genuine disease investigation and further progress in understanding molecular mechanisms of neurodevelopmental disorders.
