Description of Research

Our goal is to understand how receptor tyrosine kinases (RTK) regulate the pathogenesis of human diseases, such as cancer. This information is needed for the development of molecularly targeted therapies. To recognize aberrations of RTK signaling in diseased tissue our laboratory also works on the molecular mechanism by which RTKs control normal processes, such as embryonic development. The work mainly focuses on the ErbB family of RTKs. Our laboratory has contributed to the field by e.g. by characterizing novel RTK signaling mechanisms, by identifying novel ErbB4 isoforms, and by determining the role of ErbBs and their ligands in angiogenesis.

Current Topics

•    Screens for predictive RTK mutations
•    Novel RTK signaling mechanisms
•    Development of preclinical models for development novel RTK inhibitors
•    Sequencing of RTK inhibitor drug administration with cytotoxic agents
•    In vitro “basket trials” with ErbB inhibitor drugs
•    RTK signaling in angiogenesis and cardiovascular diseases
•    RTKs in pediatric malignancies
•    Biological role of novel ErbB4 isoforms in diseases and development

merja.haaparanta-solin [at] utu.fi

Description of Research

The general goals of the Preclinical and translational research unit are a) to evaluate and develop new PET tracers, b) to be a bridge between basic and clinical research in all areas where the PET Centre is involved, c) to be a reference core facility for basic biomedical research, d) to collaborate with pharmaceutical companies in drug development, and e) to be an important training centre for techniques related to animal imaging.


The preclinical unit actively participates in the novel radiotracer development at the Turku PET Centre including tissue penetration, target validation and metabolite analysis in experimental animals, and metabolism in the first in man studies. We collaborate extensively with the Central Animal Laboratory (CAL), the Turku Centre for disease Models (TCDM), and Auria Biobank for our research with animal models and tissues.

The preclinical unit works in numerous research projects. Among these projects are specific preclinical and basic science projects, internal collaborations with the Radiopharmaceutical chemistry unit and clinicians from different units. In addition, we have many collaboration projects with local, national, and international academic and commercial partners.

Cardiac and metabolic research
Most preclinical (nonclinical) work is done using small animals (mice, rats) whose physiology is dissimilar to human and, therefore, also the translation of imaging is challenging. The aim is to develop and validate pig models for coronary heart disease and heart failure. This work is done jointly with teams in Osaka, Canada and Kuopio. These models enable the investigation of disease mechanisms at the cellular level parallel with testing and the validation of new tracers and imaging methods. 

Oncology
The oncology group aims to improve diagnostic imaging by developing new PET tracers, evaluating their usage in different experimental settings and to translate and introduce research findings into the clinic. The research focuses on imaging the tumour microenvironment by targeting specific proteins and genes, or general processes that occurs in tumours and are important in treatment planning and therapy resistance. Proliferation, apoptosis, angiogenesis, oxygen metabolism, inflammatory response and oncogene expression is of central importance in development of novel biologically targeted agents and adaptive radiotherapy.

Neuroscience
The preclinical research in neuroscience will continue the current work in neurodegeneration, and neuroinflammation, and will expand into new research in neuropsychiatry in collaboration with radiochemistry and clinicians. The focus will mainly be on the following topics:

1) Development of novel radiotracers for neuroscience will focus on the detection of tau tangles, neuroinflammation, norepinephrine transporter and synaptic function.

2) Identification of novel mechanism of disease in neurodegeneration, neuroinflammation and psychiatric diseases, and in the identification of novel targets for tracer development and drug targeting.

Heino Jyrki: Structure and Function of Collagen Receptor Integrins

Principal Investigator

Jyrki Heino
Scientific Director, BioCity Turku (BioCity Turku)
Professor, Biochemistry (Department of Biochemistry)
jyrki.heino [at] utu.fi

Description of Research

Our research group is studying the structure¬–function relationship of the collagen receptor integrins. The most important methods used include the production of recombinant protein domains, functional assays and mutations of the domains, bioinformatics as well as the expression and analysis of the full-length receptor proteins on cell surface. This has lead to a project aimed at development of small molecular inhibitors for collagen receptors. 
In addition to the structural work we are also interested in integrin signaling, especially atypical signaling mechanisms, including low avidity integrin–ligand interaction and signaling by nonactivated integrins. Most recently, we have studied the role of collagen receptor signaling in prostate cancer and the consequences of post-translational modifications, such as citrullination, of the integrin ligands in inflammation In these experiments we use the general methods of molecular cell biology, imaging by confocal microscopy and proteomics. In a separate project we have developed new software for quantitative bioimaging (BioImageXD).

maijal [at] utu.fi

Description of Research

Our research exploits a unique scavenger receptor Clever-1, expressed on a subpopulation of immunosuppressive macrophages, to alleviate tumor related inflammation and develop Clever-1 as a companion therapeutic, diagnostic, and prognostic biomarker to treat and identify patients under immunosuppression. This involves the use of in vivo tumor models and sophisticated immunological assays with cutting-edge technology and state-of-the-art imaging combined with fresh human cancer patient material to elucidate the function of Clever-1 in controlling macrophage mediated local and systemic immune responses. Our results potentially have a high impact in understanding the mechanism of macrophage-mediated immunosuppression in cancer and promoting anti-Clever-1 immunotherapy into clinical trials where it may have benefits in comparison with currently available immune activating drugs.

pekka.e.hanninen [at] utu.fi

Description of Research

Laboratory of Biophysics develops instrumentation and methods for light microscopy, correlative multimodal microscopy and bio-analysis in general. The key application areas lie broadly within life-sciences research from basic research to applications but also in industrial processes of food technologies and industrial process waters are today on the agenda.
 
The group has recently developed new super-resolution techniques for 3D super-resolved tomography including software, super-resolution compatible nano-probes, super-resolution compatible in-vitro model for studies in bone-biology and most recently photoacoustic microscopy methods (PAM). In 2014 one of the former group members, Stefan Hell, was awarded the Nobel Prize in Chemistry for his work in the development of super-reselving microscopes, work that originated from our laboratory in the mid 90’s.
 
On the bioanalysis side, the group has developed a new type of chemical fingerprinting technique that has been applied from diagnostics of oral cancer to profiling of microbiota in the gut and analysis of bacteria in urine. The same technology has been demonstrated in several applications in the food industry and the technology has found its way also to production in the assessment of industrial process waters.
 
The group has been able to produce results that have lead both academic merits and into industrially exploited applications by a) licensing of the developed technologies to e.g. Leica Microsystems (2-photon microscopy, STED microscopy) and  b) through own startups (Arcdia International Oy and Aqsens Oy)

Description of Research

These diseases result from interaction between genetic and environmental factors. The single most important gene region regulating immune response is the (MHC) major histocompatibility complex, in humans the HLA gene complex. Polymorphisms within genes in this region are largely responsible for the genetic susceptibility to many autoimmune diseases including type 1 diabetes, celiac disease, ankylosing spondylitis, rheumatoid arthritis and multiple sclerosis.

We have performed genetic studies in the series of the Finnish Pediatric Diabetes Register and genetic screening for disease susceptibility for recruitment of subjects to several type 1 diabetes associated follow-up projects including DIPP, TRIGR, PRODIA, FINDIA, DIABIMMUNE and TEDDY where children at genetic risk have been followed-up in attempt to identify environmental risk factors and understand pathogenetic mechanisms responsible for destruction of pancreatic ß-cells.

Results based on definition of both HLA and non-HLA gene polymorphisms as well as clinical characteristics suggest heterogeneity in pathogenetic mechanisms of type 1 diabetes and different interactions between genetic and environmental factors in various phases of the autoimmune process leading to clinical disease. 

Many of the mentioned studies have included trials attempting to prevent clinical type 1 diabetes either before the appearance of diabetes associated autoimmunity (primary prevention) or after appearance of diabetes associated autoantibodies (secondary prevention).

Jalkanen Sirpa: Cell Trafficking in Cancer and Inflammation

Principal Investigator

Sirpa Jalkanen
Professor, Academician

sirpa.jalkanen [at] utu.fi

Description of Research

The overall goal of our research is to elucidate the mechanisms regulating the traffic of leukocytes and cancer cells in the body. Harmful leukocyte migration into the joints in rheumatoid arthritis and into the pancreas in diabetes are examples of diseases where leukocytes cause extensive destruction. These inflammatory diseases can be cured by inhibiting leukocyte trafficking. Also, metastasising malignant cells often use the same mechanisms as leukocytes when extravasating from blood to different organs or migrating via the lymphatics into distant sites. The results obtained can be utilized when new types of drugs are developed to treat harmful inflammations and cancer.

Description of Research

Molecular Systems Engineering is an emerging field by understanding the fundementals of molecular properties and dynamics in synthetic complex systems, and exploring sophisticated functions for advanced applications in biomedicine, materials and energy. Our laboratory uses the tools of dynamic combinatorial chemistry (DCC), supramolecular chemistry and computer chemistry to fabricate the framework of complex chemical systems, investigates the self-assembly in such systems and uncovers the working principles at molecular level behind them. We have learned that self-assembly can not only direct the formation of beautiful and intriguing structures i.e. catenanes and “Russian-doll”-like supramolecular architectures, but also promote the molecules to make copies of themselves as the living matters in nature. Currently we are trying to extend the board of DCC into the fields of materials science, enzymology and biology by three lines of research: 1) dynamic combinatorial biomaterials for controlling cell behaviors; 2) enzyme-directed DCC; and 3) DCC in vivo.

Salmi Marko: Leukocyte Traffic and the Immune Response

Principal Investigator

Marko Salmi, MD, PhD
Professor of Molecular Medicine,

masalmi [at] utu.fi

Description of Research

Leukocyte migration from the blood into tissues is critical for generation of normal immune responses. Abnormal leukocyte traffic contributes to the pathogenesis of all inflammatory diseases and several other diseases, such as cancer. We study the molecules on blood and lymphatic vessels and their counter-receptors on leukocytes, which mediate the different steps of leukocyte migration in the body. We have identified several new adhesion molecules (e.g. vascular adhesion protein-1 (VAP-1), CD73, stabilin-1, plasmalemma vesicle associated protein (Plvap)) mediating leukocyte migration, dissected the molecular mechanisms involved, and studied the therapeutic value of modulating the function of these and other adhesion receptors in inflammation and cancer. We also elucidate the differentiation of immune suppressive types of monocytes/macrophages in the body. Moreover, we analyze the value of adhesion molecules and cytokines as biomarkers of disease.

    A Novel Glycocluster Molecule for treatment of Allergy and Cancer
    Mechanisms of Specific Oral Tolerance Induction (SOTI) in Food Allergic Children

The primary objective of our interdisciplinary research is to develop new glycocluster molecules to be used in microbial, allergy and cancer vaccines. The secondary object is to explore the mechanisms of action of the glycoclusters. Immunostimulatory beta-1,2-linked mannoside cluster molecules are structurally optimized and derivatized, including new covalently linked bioconjugates and fluorine-labeled targets. Advanced NMRspectroscopic methods are applied for conformational and lectin-binding studies. Immunostimulatory properties are investigated in vitro and in vivo in murine models of allergic asthma, chronic allergic inflammation and melanoma tumors. As a result, fundamental understanding relevant to application of glycobiology to immunotherapy will be achieved.

Description of Research

We work in the field of structural biology and structure-based drug design. Our main methods are x-ray crystallography and cryo-electron microscopy. The main focus of our research is the unraveling of molecular mechanisms governing the interplay between microbial pathogens and their hosts, and the exploitation of these finding in medicine. We are particularly interested in host-pathogen interactions during the early steps of infection: bacterial attachment and biofilm formation mediated by fimbrial adhesins and host tissue invasion mediated by the Type III secretion system. Blocking these steps could prevent infections caused by antibiotic-resistant pathogens. Another line of our research explores the intricate cell signaling mechanism of the novel growth factor-enzyme, adenosine deaminase type 2 (ADA2). This study paves the way for the development of novel means to treat blood cancers and vascular disorders, including a genetic disease called deficiency of ADA2 (DADA2). In addition, we develop a novel ADA-based immuno-oncological therapy of advanced cancers.
