Sue Gibbs


Sue Gibbs is professor in Skin and Mucosa Regenerative Medicine. She is PI at the Department of Molecular Cell Biology & Immunology and also in the Department of Oral Cell Biology, ACTA. Her entire career has focused on animal alternative methods, in particular in developing human healthy and disease models drug discovery, pre-clinical studies and safety testing. She combines cutting-edge research in cell biology and immunology with advances in tissue engineering. Current focus lies with developing next generation immune competent tissue engineered constructs to investigate the (patho)physiology of adverse scar formation and to investigate similarities and differences between tolerance, allergic and irritant contact dermatitis with the aim of identifying novel drug targets for personalized as well as general therapeutic strategies. Recently, her research has extended into the field of hair follicles and importantly ‘’organ-on-a-chip’’, in particular immune competent skin-, gingiva-, gut,- lymph node- and melanoma- “on-chip”. Sue Gibbs was awarded numerous grants from EU, NWO, TTW, Dutch Burns foundation, in collaboration with partners from industry.

Human healthy and disease model technologies: Immune competent Skin-on-Chip for risk assessment and cancer research: NextSkin project

Our aim is to develop the next generation immune competent human skin models which closely represent healthy and diseased skin, thus providing a platform for safety and efficacy testing of drugs and consumer products which come into contact with our skin. Our focus is on fibrosis, cancer, allergy and tolerance.  Cell types which can currently be built into our organotypic models include epithelial cells (keratinocytes, melanocytes, Langerhans cells, melanoma), dermal cells (fibroblasts, myofibroblasts, hair follicles, blood and lymph vessel endothelial cells, dendritic cells, monocytes, macrophages) and adipose tissue cells (mesenchymal stromal cells, adipocytes and endothelial cells). These models are being incorporated into micro-physiological bioreactors, ‘’organ-on-a-chip’’, to create immune competent skin-, gingiva-, gut,- lymph node- and melanoma- “on-chip”.

Inflammatory skin and oral mucosa disease

Research is aimed at identifying the mechanisms involved in skin and oral soft tissue homeostasis and inflammation. Examples of our research questions include: why does a deep skin wound heal with a bad scar formation whilst oral wounds heal with relatively little scar? Is this to do with intrinsic properties of the cells or is this due to extrinsic factors e.g.: saliva, microbiome? With the aid of normal skin / gingival equivalents, and in vitro hypertrophic scar and keloid scar equivalents the mechanisms of scar formation can be investigated. Another major research question is: why does first contact with an allergen (e.g. Nickel) via the skin often result in sensitization whereas first contact via the mouth with the same allergen results in tolerance? With the aid of skin and gingival equivalents containing integrated Langerhans Cells, innate and adaptive mechanisms involved in sensitization versus tolerance and pathogen infection are being investigated.

My project aims to develop a functional 3D organotypic lymph node with integrated lymphatics that mimic adaptive immune responses. Combining research on lymph node stromal cells and current in-house expertise of tissue engineering & microfluidic devices, the overall objective of the project is to design an organ-on-chip model that features lymphatic drainage of an immune competent gut into a lymph node. The immunosurveillance capability of the model will then be assessed by inducing an inflammatory response, leading to its availability as a future platform for rheumatoid arthritis drug testing.

Maarten Witte


Maarten Witte is group leader in the Department of Molecular Cell Biology & Immunology and part of the MS center Amsterdam. Throughout his career, he has been fascinated by the interplay between perhaps the two most complex systems in the human body, the immune and central nervous system (CNS), and how neuroinflammation contributes to neuronal damage in neurological diseases. Supported by grants from the US Department of Defense, Institute of Chemical Immunology (NWO) and an MS fellowship from the Dutch MS research foundation, his group aims to elucidate the immunological mechanisms that drive neurodegeneration in several neurological diseases, in particular multiple sclerosis (MS). To disentangle these neurodegenerative pathways, they study human post-mortem tissue and various in vitro and in vivo model systems using both state-of-the-art microscopy and single cell approaches. 

Research Line

Although the central nervous system has traditionally been defined as ‘immune-privileged’, research over the last decades has taught us that there is considerable interaction between the peripheral immune system and the brain in both health and disease. Similarly, we have come to appreciate that CNS-resident immune cells, particularly microglia, are not only involved in protecting the brain from pathogens and clearing debris, but play multiple critical roles in development, homeostasis and degeneration of the CNS. 

Inflammation-driven neurodegeneration in MS

Here, we aim to identify which infiltrated peripheral immune cell subsets drive neurodegeneration in progressive MS and to elucidate the mechanisms involved. We are particularly interested in the role of meningeal immune cells and how they might affect cortical microglia and neurons. Hopefully, this will allow us to identify novel therapeutic targets to stop neurodegeneration in progressive MS, which at present cannot be treated.

Neuron-microglia crosstalk in health and disease

Recent literature suggests that direct, physical interaction between microglia and neurons is essential in maintaining neuronal function during brain homeostasis, and can be both neuroprotective and neurodegenerative under neuroinflammatory & neurodegenerative conditions. We aim to study cause and consequence of this physical interaction in health and disease by using newly developed photoactivatable ligands. These photochemical tools allow us to control the activation of individual microglia in vitro and in vivo and to subsequently assess the interaction between microglia and neurons.

Febe van Maldegem


Febe van Maldegem is group leader in the Department of Molecular Cell Biology & Immunology. Her work focusses on the complex role of the tumour microenvironment in non-small cell lung cancer (NSCLC), crucial for mediating anti-tumour immunity, but more frequently imposing resistance to therapy. Key to her work is the use of highly multiplex technologies, such as Imaging Mass Cytometry with which the tumour microenvironment can be studied in great detail, revealing the activation states as well as the spatial context of the many cells within the tissue. Febe van Maldegem’s research program, supported by award of the Amsterdam UMC fellowship, aims to improve therapeutic options for patients with non-small cell lung cancer by rationalising the design of combination, mindful of the important role for the tumour microenvironment in determining success.

Research Lines

The NSCLC TME as biomarker and therapeutic target

In order to understand how we can manipulate the TME to benefit therapeutic strategies, we will first need to better understand the dynamics within this complex system. This research line asks the basic questions: How does the TME evolve over time during tumour development, and what are the selective forces that drive this evolution? In several in vivo models for non-small cell lung cancer we study the changes in TME composition, at early time points from tumour onset into advanced tumour stages and under different experimental conditions. Imaging Mass Cytometry will provide detailed phenotypic and spatial characterisation of the cellular relationships in the tissue. The resulting spatial TME profiles will be used to generate biomarkers for response to therapy and to design novel therapeutic targets aimed at disrupting or enhancing cellular interactions. 

Video, sequentially highlighting 15 out of the 27 markers this small lung tumour was stained for using Imaging Mass Cytometry (CX3CR1, PECAM, aSMA, EPCAM, B220, CD103, LY6G, CD8, CD4, CD11c, CD68, F480, CD45, CD44, MHC-II)

Rationally combining chemoradiotherapy with immune checkpoint inhibitors (ICI)

Neoadjuvant (chemo)radiotherapy (CRT) is the current  standard of care for low grade NSCLC, but the field is moving towards combinations with ICI. Chemotherapy and radiotherapy can benefit immune responses by inducing immunogenic cell death, but can also be toxic to the immune cells. We will assess the impact of this treatment combination by analysing patient samples from current clinical trials, comparing different combinations of these therapies in pre- and post-treatment biopsies. In vitro and pre-clinical studies will be used to optimise the treatment dosing and scheduling, to provide a rational basis for design of the next generation of clinical trials.

Gijs Kooij


Gijs Kooij is a PI (assistant professor) at the Department of Molecular Cell Biology & Immunology as well as the MS center Amsterdam. His main research focus is to understand the natural process to resolve neuro-inflammation in order to provide new perspectives on the pathogenesis of chronic (unresolved) neuro-inflammatory diseases like multiple sclerosis (MS) and to reveal new treatment opportunities. He recently discovered endogenous lipid mediator circuits in the central nervous system (CNS) and revealed the absence of protective lipid mediators in various disease stages of MS. These findings in combination with personal Vidi (NWO) and Fellowship (Dutch MS society) grants have enabled him to establish his own research group on inflammation-resolution mechanisms in health and disease.

Research Line

(Re)solving MS: Understand and exploit endogenous protection mechanisms.

Inflammation is a host-protective response when properly orchestrated. Beside immune checkpoints, the inflammatory cascade boasts an additional checkpoint, driven by chemical lipid mediators that induce resolution of inflammation. These novel autacoids, called specialized pro-resolving lipid mediators (SPMs), not only inhibit the inflammatory response, they also actively terminate it, leading to the restoration of tissue homeostasis. Novel sensitive detection methods (i.e. lipidomics) have set the stage to identify and decode these SPMs, which opens new perspectives on the pathogenesis of chronic (unresolved) inflammatory diseases like multiple sclerosis (MS).

By using a state-of-the-art lipidomics and mass-spectrometry imaging approach in combination with primary cell cultures, ex vivo brain slice cultures, in vivo neuro-inflammation models and human post-mortem tissues, we will elucidate in the coming years how altered inflammation-resolving mechanisms underlie MS pathogenesis by investigating both fundamental (Vidi) and clinical (fellowship) aspects. His ultimate goal is to provide novel diagnostic, prognostic and therapeutic opportunities for MS and other chronic (neuro-)inflammatory diseases based on resolution pharmacology (Figure 1).

Figure. Decision paths during neuro-inflammation: chronicity or resolution?
An effectively mounted inflammatory response will also trigger the activation of protective resolution pathways intended to safely terminate the inflammatory cascade and promote healing (1). Failed resolution can extend in time the actions of pro-inflammatory mechanisms resulting in prolonged (chronic) inflammation (2). I here propose that activation of endogenous circuits of resolution through novel resolution-based therapeutics (SPMs) can restore tissue structure and function to return to homeostasis (3).

Neuro-immunology: The neurovascular unit in health and disease                  

Altered activation of the immune system, neuroinflammation (marked by activated astrocytes and microglia), and dysfunction of the neuro-protective brain barriers are pathological hallmarks of many neurodegenerative disorders, such as multiple sclerosis (MS), various forms of dementia, including Alzheimer’s disease (AD),  and stroke. It becomes increasingly clear that chronic neuroinflammation, an altered immune response and neurovascular dysfunction may even be causal for onset and progression of such cognitive disorders, but underlying mechanisms remain unknown. The translational research of the De Vries group is therefore focused on understanding how alterations at the level of the immune system and the brain barriers underlie neuroinflammatory and neurodegenerative conditions.  In the current research, we aim to define underlying pathways that initiate neuro-inflammation as potential targets for treatment and identify if such alterations may serve as biomarkers for disease in well-defined patient cohorts. A better understanding of such pathological processes may in future not only lead to new diagnostic tools that reflect ongoing neuro-inflammation and brain barrier dysfunction, but may also lead to potential novel intervention strategies to fight neurogical disorders.

In the past years, the neurovascular unit has been overlooked in leukodystrophies, while it can have significant implications in the disease progression and in treatments. Using a multidisciplinary approach, I collaborate with pathologists, clinicians and biologists in order to unravel the underlying mechanisms in these diseases. For these studies, I use human post-mortem tissue, in vivo and in vitro approaches.

How does aberrant tumor cell glycosylation affect tumor cell biology?

Cellular glycosylation is a highly dynamic process that alters upon activation, inflammation, and oncogenic transformation. Although it has been known for decades that cell surface glycans are highly diverse, it is still unclear how glycan heterogeneity is established and how this impacts tumor cell biology and tumor-immune cell recognition. We employ CRISPR/Cas9 genome engineering (both gene knockout as well as gene induction strategies) to generate isogenic tumor glycovariant cell lines. We assess the effect of tumor cell glycosylation on 3D tumor growth, as well as tumor cell differentiation, angiogenesis and drug resistance. Our new preliminary data (amongst others from RNAseq) points to an important role for cancer glycosylation in shaping tumor cell metabolism, epithelial-to-mesenchymal transition (EMT) and cancer stemness and this entails our future focus.

How does the tumor-associated glycome affect anti-tumor immunity?

Within the immune system, glycan blue prints are decoded by specific glycan-receptors, such as the C-type lectin (CLRs) or the Siglec receptors. These glycan-binding receptors are crucial in regulating the balance between immunity and tolerance and several CLRs and Siglecs seem to endow a tolerogenic phenotype on antigen presenting cells (APCs) to dampen potential immune responses directed against the tumor. We study this by correlating lectin binding to disease progression and immune cell infiltration and activation in human tumor samples.
To assess the immunological consequences of altered tumor glycosylation on a molecular level, we stimulate lectin receptors on dendritic cells and macrophages with synthetic glycoconjugates and glycan-modified dendrimers. These glycan-conditioned APC are subsequently profiled by RNAseq and characterized for their maturation marker expression, cytokine secretion and their ability to instruct effector and regulatory T cell responses. We are currently addressing whether targeting of lectin receptors also alters the metabolism of antigen presenting cells.

I’m investigating the signaling of the C-type lectin receptor MGL in dendritic cells in more detail by looking at, for example, the cytokine production, co-stimulatory and inhibitory receptor expression and gene expression patterns. With different MGL ligands, that induce a different conformation in MGL after binding, we hope to steer the immune response started by the dendritic cells in different directions.

Primary Immunodeficiencies

Primary Immunodeficiencies (PIDs) are a heterogeneous group of genetic disorders that affect functioning of the immune system and manifest with severe and/or recurrent infections. We identify causative mutations using whole exome or whole genome sequencing and then undertake detailed functional molecular analyses of the affected cellular pathways to uncover mechanisms leading to disease phenotypes. In this research, we closely collaborate with clinical scientists working with PID patients.

Our previous work includes the discovery of the Activated PI3K-Delta Syndrome (APDS), which is caused by a rare dominant gain-of-function mutation in phosphoinositide 3-kinase δ (Angulo et al, Science, 2013). APDS patients have antibody deficiency, suffer from recurrent respiratory infections and rapidly develop airway damage (bronchiectasis). Today, genetic analysis allows rapid diagnosis of APDS patients and they are being identified all around the world. Our findings also indicated that selective PI3Kδ inhibitors may provide a novel specific and efficient treatment for APDS, and this is now being tested in clinical trials. Furthermore, building on the findings in APDS patients we now investigate the role of human PI3Kδ in common diseases.

Our recent findings also include another novel PID, the complete RIPK1 deficiency. We showed that RIPK1-deficient immune cells have impaired proinflammatory signalling and are prone to cell death via the necroptosis pathway, which leads to dysregulated cytokine production, severe immune deficiency, arthritis and early-onset inflammatory bowel disease (Cuchet-Lourenco et al, Science, 2018). This finding highlighted the pivotal role of RIPK1 in the human immune system.

Host-pathogen interaction in tuberculosis

Tuberculosis (TB) is the leading cause of death among infectious diseases. People can be genetically predisposed to TB. Susceptibility to pulmonary TB is determined by combinations of multiple common DNA variants each having a small effect. To identify such variants, thousands of TB patients and healthy controls have to be studied. Previously, we have done a genome-wide association study in more than 11,000 subjects and identified a novel mechanism in TB mediated by the ASAP1 protein that controls dendritic cell migration (Curtis et al. Nat Genet 2015). Now we use CRISPR-Cas9 technology to further dissect mechanisms of interaction between human cells and Mycobacterium tuberculosis and develop novel host-directed therapies against TB. This research is funded by the ERC Advanced grant.

Reina Mebius


Reina Mebius is professor in Molecular Cell Biology at the Department of Molecular Cell Biology & Immunology. She has contributed to the field of lymphoid organ development showing that communication between stromal cells and immune cells is crucial for the forming of lymph nodes. The realization that immune cell interaction with stromal cells is central to lymph node formation started another new research field in which the importance of stromal cells for the immune system is studied. Now the different roles that various stromal cell subsets have on the immune response during homeostasis and disease is further dissected using advanced techniques such as single cell RNA sequencing and fluorescence is situ hybridization, in order to discover novel points of interference for targeted therapy in autoimmunity and cancer.

Research Line

Functional development of the immune system

Lymphoid organs are built by a network of stromal cells, which are instrumental for formation of these organs in early ontogeny. Secondary lymphoid organs and their compartments greatly enhance the odds that rare antigen-specific T cells encounter dendritic cells that present the antigen and are thus crucial for effective immune responses. We study this process of lymph node formation and the cellular and molecular mechanisms that are required to form these highly organized lymphoid organs. Special attention is paid to the differentiation requirements of stromal precursor cells to the different stromal subsets that are present in adult lymphoid organs.

Figure, adapted from Koning et al, J. Immunology 2016, showing stromal cells in developing lymph nodes (left) in which the green and blue indicate stromal cells and red the immune cells and stromal cells in adult lymph nodes (right) in which different stromal cell subsets are indicted by red, blue and green.

Environmental control of the immune response

Stromal cells within the lymph nodes are able to convey location specific as well as survival signals to immune cells. The formation of lymphoid compartments is not restricted to ontogeny, since ectopic lymphoid structures are formed during chronic inflammatory diseases as well in solid tumours, where they can either contribute to the inflammatory response or an anti-tumour response, respectively. Within the organized structures various different stromal subsets are present, each with their own function. Further characterization of these functions reveal more specifics by which the immune system is controlled by its environment.

In addition, the micro environmental control outside of organized lymphoid organs are studied in inflammatory diseases as well as in cancer in order to better understand how the micro-environment contributes to disease.

Combining research on lymph node stromal cells and current in-house expertise of tissue engineering & microfluidic devices, the overall objective of the project is to design an organ-on-chip model that features lymphatic drainage of an immune competent gut into a lymph node. The immunosurveillance capability of the model will then be assessed by inducing an inflammatory response, leading to its availability as a future platform for rheumatoid arthritis drug testing.

Glyco-code in cancer and inflammatory diseases

We explore the innate immune system, with a focus on dendritic cells and macrophages, to develop novel therapeutics in cancer and inflammatory diseases.  Dendritic cells and macrophages have unique properties to act as  sensors for local changes and respond to tissue injury by producing inflammatory mediators or help  to eliminate injury and restore tissues. We study innate  glycan binding receptors that recognize glycosylated structures on pathogens or (altered) tissues, modulate immune activating or regulatory  programs of dendritic cells and myeloid cells. We investigate how binding of carbohydrates, altered due to tissue inflammation or wound healing processes, control modulation of immune cells  through recognition/signaling of glycan binding receptors, such as C-type lectins and Siglecs. We explore how glycan- glycan binding receptor control the immune signature and regulate tumor growth or pathogen recognition and inflammation.  Using transcriptomics and single cell sequencing we explore differential expression of glycosylation related genes in cancer patients tissues to unravel altered glycosylation signatures, to predict for survival benefit, response to therapy, and glycan induced immune modulation. We investigate how the glyco-code of the tumor-stromal network affects immune regulation. Using high dimensional cytometry and multiplex imaging we aim to define novel myeloid suppressive pathways in the tumor microenvironment of NSCLC, melanoma and PDAC. We also unravel how innate glycosylation in (tumor)tissue exert their effect on T cell and NK(T) cell function. New glycan immune regulatory programs will be studied in CRISPR-Cas9 generated glycan modified tumor/stromal mouse and human models, and glyco-code modifying therapies will be developed to revert suppression into tumor specific immunity. Next to cancer we study altered glycosylation processes in inflammatory diseases, such as rheumatoid arthritis, aimed to restore the immune balance towards suppression of the disease.

Glycan modified immune therapy for cancer and allergy

Professional antigen-presenting cells such as dendritic cells (DC) and Langerhans cells (LC) have also the capability to induce long-term cellular immunity.  We investigate  glycan binding receptors  such as C-type lectins and Siglecs on innate myeloid, macrophages and DC for targeting purposes to guide glycosylated antigens binding and uptake that influence antigen presentation, T cell differentiation and immune cell signaling. The cancer nano-vaccines we  develop use specific glycans that target receptors such as DC-SIGN and Langerin that  stimulate anti-tumor immunity, in human skin models and in-vivo mouse tumor models.  Using high dimensional flow analysis  local and systemic immune infiltrates and dynamics of the tumor microenvironment are studied. These DC targeting vaccines are combined with  immune checkpoints or other combinatorial therapies that alter immune regulatory processes in the tumor-microenvironment.  Immune inhibitory vaccines for treatment of auto-immune diseases and allergy use glycans that target glycans that interact with immune inhibitory receptors such as Siglecs.  We explore  T cell differentiation processes, antibody isotype responses, and the effect on innate immune cells, such as neutrophils and mast cells. Through fundamental discovery we aim to apply knowledge on glycan-DC modifying processes to be implemented in the treatment of cancer and inflammatory diseases.

I am the Early Stage Researcher 13 of the Glytunes network ( My project is focused on the study of sialylation, the process by which a glycan called sialic acid is added to proteins and lipids. An increased expression of sialic acid on the surface of cells is a hallmark of cancer, and this glycan can interact with receptors on immune cells called Siglecs. Consequently, the sialic acid-Siglec axis represents a novel immune checkpoint to be exploited for anti-cancer therapies. During my PhD, I will study this interaction and use different approaches to target it using both in vitro and in vivo models of melanoma, pancreatic cancer and lung cancer.

PhD student
The focus of my research is the development of designer bacterial nanoparticles for cancer immunotherapy. We engineer the particles into semi systemic scaffolds that can be targeted for precise delivery and contain tailored immune modulatory properties. Subsequently, we analyze the distribution of the particles in vivo and test the prototype vaccines for therapeutic cancer treatment in vivo.
