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 Research 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

Description of Research
Our translational research focuses on evaluating and validating PET tracers for imaging the tumor microenvironment. We are especially interested in approaches for determining the level of radioresistance in solid tumors that affect radiotherapy treatment outcomes in cancer patients. Such tracers can be utilized for treatment planning and follow-up purposes in clinical settings. Another objective is to re-evaluate some existing tracers for their possible use as cancer imaging tools or to measure changes in cancer-dependent metabolism pathways on a whole-body level, which might affect treatment outcomes. We combine PET technology with state-of-the-art technologies for molecular biology utilizing cell lines, tumor models, and patient-derived samples.

Description of Research
My research interest is on validation and use of novel positron emission tomography (PET) radiopharmaceuticals (radiotracers) developed at Turku PET Centre. The main targets are receptors, transporters, abnormal proteins and neuroinflammation in the central nervous system.
In my research, I focus on investigating the pharmacokinetics of new PET tracers in healthy and animal disease models by utilizing noninvasive PET imaging techniques that provides a functional or metabolic assessment of normal tissue or disease conditions. This in vivo imaging is combined with computed tomography (CT) and with ex vivo digital autoradiography. An important part of my research is also the method development and analyses of radioactive metabolites of PET tracers during the time course of imaging."

Description of Research
Our group investigates the pathophysiology, prediction and treatment of breast cancer-related lymphedema. We study the tissue composition and gene expression of both normal and lymphedematous skin and adipose tissue, with a particular focus on immune cells. We use single-cell RNA sequencing, spectral flow cytometry and immunofluorescence staining to obtain a comprehensive view on which cellular and molecular mediators are responsible for the initiation of adipose deposition and fibrosis in lymphedema. We are also characterizing the changes that take place in lymphatic endothelial cells as lymphedema progresses. Our aim is to clarify the pathophysiology of lymphedema and to pave the way for novel therapeutic approaches for this chronic and debilitating condition.

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).

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.

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.

Description of Research
Our aim is to understand the means cancer cells use to develop resistance to cancer therapies. Our special focus are the mechanisms that enable the establishment of minimal residual disease, or govern the maintenance of residual tumors following targeted cancer therapy. The overarching goal of our research is to develop rational combination strategies that will extend the long-term efficacy of clinically used cancer therapies.
While targeted therapy has transformed the treatment of cancer, the long-term efficacy of these strategies is hampered by acquired drug resistance. In many cases, clinical drug resistance is preceded by minimal residual disease (MRD) state, where residual tumors stay dormant for an extended period of time. Emerging evidence indicates that the establishment of MRD is mainly regulated by non-genetic mechanisms, as cancer cells adapt to treatment by acquiring new phenotypic states that no longer depend on the targeted oncogene. These slow-cycling drug tolerant cells can regain proliferative state upon drug withdrawal or acquisition of additional resistance mechanisms, and as such serve as a reservoir of dormant cells capable of re-initiating the growth of a drug resistant tumor. Understanding the mechanisms underlying the establishment or maintenance of minimal residual disease would enable the development of rational combination strategies aimed to prevent or limit residual disease, leading to prolonged survival of cancer patients.

We investigate the regulation of B lymphocyte activation that mounts specific and highly effective antibody responses against pathogens. However, if lymphocyte activation is defected, we face pathological conditions such as autoimmunity or lymphoma. In our research, we integrate advanced light microscopy and proteomic approaches with cellular and in vivo models, to gain novel understanding on the cell biological phenomena of B cell activation and immune responses.

Description of Research
Tissue resident macrophages are long-lived cells that are distributed throughout the body and migrate into the tissue during embryogenesis. They are specialized in ingesting and processing dead cells, debris and foreign materials, and in the recruitment of other immune cells – like monocytes – to sites of injury in response to inflammatory signals. Monocytes, on the other hand, represent short-lived cells that can be found in the peripheral circulation. Traditionally, it was assumed that monocytes represent an intermediate stage, linking mononuclear phagocyte precursors in the bone marrow with terminally differentiated tissue resident macrophages. However, this concept seems to hold true only for certain tissues. In most of the cases, embryo-derived tissue macrophages are endowed with an intrinsic self-renewal program to maintain homeostasis, while monocyte descendants are devoid of this capacity. Instead, monocytes are highly plastic cells and can differentiate – depending on the cellular context – into various cell types with fundamental different functions like effector monocytes, monocyte-derived dendritic cells and monocyte-derived macrophages.
The transcription factor C/EBPβ is expressed in cells of the myeloid lineage, especially in monocytes, macrophages and dendritic cells. Recently, we applied epigenetic approaches to identify C/EBPβ as one of the main regulators of monocyte and Alveolar macrophage development under physiological conditions. Deficiency of C/EBPβ in mice let to a complete absence of Ly6C- monocytes due to impaired induction of the monocytic survival factor Nr4a1. In Alveolar macrophages, C/EBPβ controlled the expression of a lipid catabolic program.
We are currently investigating the differentiation of myeloid cells under steady state as well as pathological conditions such as autoimmunity in various tissues using epigenetic approaches including ATACseq, ChIPseq and high resolution immune profiling like scRNA-Seq. The central goal of our laboratory is to identify new factors that are involved in the differentiation of monocytes and macrophages under pathological conditions. We hope to manipulate the fate and activation status of macrophages and thereby beneficially influence disease progression.

Description of Research
The long-term goal of our projects is to further understand how cellular metabolism control immune activation, cancer cell growth, and the life cycle of human cytomegalovirus (HCMV) that appears to be closely involved in the pathogenesis of inflammatory disease and cancer. We hope that this will allow us to find new treatment strategies for many of our common diseases. Our research is carried out at Turku University, MediCity Research Laboratory and Karolinska Institutet.
HCMV is a common virus, infecting 70-90% of the worlds population. This virus is considered harmless for healthy individuals but may cause severe disease in immunocompromised patients. Emerging evidence also imply a role of this virus in inflammatory diseases and cancer. HCMV is reactivated by inflammation, can drive inflammatory processes and is often found in inflamed tissue specimens obtained from patients with inflammatory diseases such as SLE, rheumatoid arthritis, inflammatory bowel disease, cardiovascular diseases and aortic aneurysms, while rarely detected in healthy tissues. HCMV is also commonly found to be active in tumors of different origin such as glioblastoma, neuroblastoma, medulloblastoma, breast, colon, prostate and ovarian cancer. Both primary tumors as well as metastases are virus positive, while healthy tissues surrounding tumors and metastases are virus negative. We are currently studying the effect of anti-HCMV therapy in 220 glioblastoma patients in a randomized trial, VIGAS2. Retrospective analyses of so far treated patients (139 patients) indicate substantial prolonged survival time in patients receiving anti-viral therapy, which suggest a potential role of this virus in cancer.
Activation of immune cells depend on alterations in cellular metabolism; i.e the Warburg effect, which is also essential for cancer cells to grow. HCMV establishes the Warburg effect in infected cells, which appears to be essential for reactivation of latent HCMV and virus production Thereby our studies of viral regulation of cellular metabolism unifies the many diseases associated with HCMV. Although the metabolic alterations to the Warburg effect is essential for inflammation and cancer, it is not known how cells switch from normal metabolism to the Warburg effect. We have used HCMV as a tool to try to understand the underlying mechanisms of the Warburg effect in immune cells and cancer cells. We made unexpected insights into how cells with a normal metabolism switch to the Warburg effect, which allowed us to identify metabolic inhibitors that we are now testing how they affect immune cell activation and cancer cell growth.

Description of Research
Leukocyte migration from the blood and lymph 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 molecular mechanisms and functional implications 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)) on blood and lymphatic vessels and leukocytes, which mediate different steps of leukocyte extravasation from the vessels.
We have also studied the therapeutic value of modulating the function of these and other adhesion receptors in inflammation and cancer. We also elucidate the differentiation pathways of monocytes/macrophages by studying the role of the developmental origin and tissue niche for their plasticity and functions. In addition, we are interested in defining the routes by which antigens enter the lymph node parenchyma via the lymphatic vasculature during the triggering of immune responses. As a separate line of research, we have analyzed the value of adhesion molecules and cytokines as biomarkers of disease in population and patient cohorts.

Description of Research
Although immune cells play a critical role in human diseases such as infection and cancer, structural cells including endothelial and stromal cells are also crucial for maintaining the function of the immune cells. Recent single-cell technologies showed multiple heterogenous subsets in structural cells that have not been considered before. The aim of our group is (1) to find unrecognized heterogeneous structural cell subsets in human organs including lymphoid organs and tumors using single-cell technologies, and (2) to find the new molecular mechanism between heterogeneous structural cells and immune cells in health and disease.

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.

Description of Research
The main focus of our research is to understand the function of human brown adipose tissue in health and in metabolic disorders. Current projects are focused on ascertaining the crosstalk between the gut microbiota/products and the immune system with brown adipose tissue function in humans.
This project functions under the framework of the INFLAMES flagship, funded by the Academy of Finland, and aims to: i) ascertain how the infiltrated immune cells within brown adipose tissue modulate its function, and ii) ascertain the mechanisms by which an inflammatory environment may induce brown adipose tissue dysfunction.
