​​Novel Network-Based Approaches for Studying Cognitive Dysfunction in Behavioral Neurology

Project description: The project will employ novel behavioral paradigms and state-of-the-art imaging techniques to:

  • identify neural underpinnings of language, speech and cognitive impairment in different patient groups (stroke, Parkinson’s disease, dementia) across three languages (Czech, English, Hungarian),
  • unravel the therapeutic potential of NIBS (non-invasive brain stimulation) by targeting and modulating distinct brain networks in these patients

The international collaboration between partners builds on the complementary expertise of researchers, promotes the transfer of knowledge, provides infrastructure to develop the careers of the staff members, and develops a new model for training future generations of behavioral neurologists.

​​ Excellence in research and development of non-coding RNA DIAGnostics in ONcology

Project description: RNADIAGON is an academic-industrial consortium focused on research and development it the field of non-coding RNA diagnostics in oncology. This consortium enables development of personal skills and knowledge of early-stage and experienced researchers from 5 European academic centers through their (i) long-term stays at the US research center of excellence (MD Anderson Cancer Center, University of Texas, USA) and (ii) traineeships at the education center and manufacturing facilities of industrial partner (BioVendor, Inc.) developing certified (CE-IVD) diagnostics, who will work on the development of a new non-coding RNA diagnostic kit in colorectal cancer adopted here as a model project.​

Protection from malaria in the Fulani ethnic group of West Africa involves reduced levels of A-to-I RNA editing by ADAR1

  • Principal Investigator: Jaclyn Elizabeth Quin, Ph.D.
  • Acronym: QuinADAR1
  • Project type: H2020 Excellence Science - MSCA-IF
  • Implementation period: 01.06.2019 - 31.05.2021
  • Budget:  144 980.64 EUR 

Project description: I will investigate what mediates an effective human immune response to infection with Plasmodium falciparum malaria.

I will approach this through studying the Fulani ethnic group of West Africa, who are relatively resistant to malaria infection. The basis of the Fulani protection from malaria has never been established. However, we have performed a pilot study which suggests that reduced levels of adenosine-to-inosine (A-to-I) editing of RNA by ADAR1 following P. falciparum infection can drive a more effective innate immune response in the Fulani.

We have an established collaboration with the Malaria Research and Training Centre at University of Sciences Technique and Technology in Mali, who have strong ties to the Fulani community. At Stockholm University, I have had the opportunity to develop a strong background in immunology research techniques, specifically utilizing in vitro models of malaria infection in human monocytes, in the research group of Eva Sverremark-Ekström. As the role of RNA modifications is an emerging field, I plan to move to CEITEC, Czech Republic, to work with Mary O’Connell, who has pioneered the role of A-to-I RNA modification in the innate immune response to RNA.

Specifically, we will test the hypothesis that reduced rates of A-to-I editing of RNA in the Fulani following infection enables them to mount a more effective innate immune response to P. falciparum malaria, and contributes to their relative protection from the disease. Further, targeting of ADAR1 and/or reduction in levels of A-to-I RNA levels may present a novel strategy to boost effective immune response to malaria.

Using Deep Learning to understand RNA Binding Protein binding characteristics

  • Principal Investigator: Panagiotis Alexiou, PhD
  • Project type:  H2020 Excellence Science - MSCA-IF
  • Implementation period: 01.07.2019 - 09.05.2022
  • Budget:  156 980.64 EUR 

Project description: New technologies have revolutionized our understanding of RNA binding protein (RBP) function. Global screens for RBPs have pulled down hundreds of proteins for which no discernable RNA Binding Domain is present. These proteins, termed enigmRBPs due to their enigmatic nature, do bind RNA in unknown and variable fashion. An ever increasing number of such RBPs are having their target sites identified via CrossLinking and ImmunoPrecipitation Sequencing techniques (CLIP-Seq). This torrent of data can be harnessed by novel Deep Learning techniques to identify high order characteristics of RBP function.

The aim of this proposal is the development of a machine learning model that can explore the functional implications of RBP binding characteristics. A model that, given an enigmatic RBP, can identify other known RBPs that show similar binding characteristics, such as sequence motifs, conservation motifs, secondary structure motifs, and higher order combinations of the above.

We will focus on methods to practically interpret the machine learning model to biological knowledge, especially higher order filters that can learn the interplay among varied input, such as secondary structure, sequence and conservation. Beyond the theoretical, we will disseminate our methods in easy to use, standalone and web application format, in order to increase the practical application of our research.

We are transplanting expertise from the bioinformatics and machine learning field, into a fertile substrate of RNA biology and CLIP-Seq experimentation. This interdisciplinary project will involve close collaboration and two-way transfer of knowledge in a dynamic research environment.

LightDyNAmics. DNA as a training platform for photodynamic processes in soft materials

Project Description: The main goal of LightDyNAmics is to achieve a complete understanding of the ultrafast dynamical processes at the molecular scale induced by UV light absorption and DNA, and to einveil the mechanisms leading to photodamage of the genetic code. The project will transfer this knowledge to a broad class of optoelectronic materials, highly relevant for Europe's high-tec industries.
At the same time, LightDyNAmics will train 15 Early Stage Resarchers by crossing the border between theoretical and experimental expertise by performing independent, yet interrelated and complementary research projects focussed on three scientific objectives:

  •  to develop and optimize a variety of complementary experimental and computational methods for the investigation of ultrafast dynamics in multi-chromophore systems;
  • to apply these methods to elucidate photoinduced processes in DNA tracts of different size and complexity, from simple nucleobases in the gas phase to genomic DNA, over different timescales from light absorption all the way to the formation of lesions;
  • ​​to generalize the acquired knowledge and transfer it to other multi-chromophore, soft materials of fundamental and technological interest, identifying the photoinduced processes, their spectral signatures, their yields and dynamics.
