This functional genomics project aims at understanding the biology of the underlying mycelium differentiation and autolysis processes in much more detail.

Almost all bacteria are enveloped by a cell wall that provides cellular protection.

This thesis describes the design and synthesis of fragments of various cell wall carbohydrates of the Streptococcus species, including the branched Group B-specific antigen (GBC) of Group B Streptococcus, glycerol phosphate (GroP) modified group A carbohydrate (GAC), and the O-acetylated type 1 capsular…

Aspergillus niger is an important industrial producer of organic acids and enzymes producing large amounts of spent fungal biomass.

The central question of this Vici proposal is to investigate if, and how actinobacteria exploit life without a cell wall.

Streptomyces are multicellular, Gram-positive bacteria in the phylum of actinobacteria which produce a high amount of bioactive natural products of which the expression is tightly coordinated with the life cycle.

CONCLUSION: This study demonstrates that human macrophages can be induced to exert direct anti-tumor activity against osteosarcoma cells. Our observation that the induction of macrophage anti-tumor activity by L-MTP-PE required IFN-gamma may be of relevance for the optimization of L-MTP-PE therapy in…

Thread-like bacteria make cells that no longer have a cell wall under the influence of osmotic stress. A remarkable discovery, since the cell wall serves as a protection barrier for bacteria. It could also help to explain how pathogenic bacteria can hide in our body from our immune system. A team of…

Are Weyl particles the ideal conductors? Do cells without a cell wall play a role in chronic Tuberculosis infections? Carlo Beenakker and Dennis Claessen want to answer these questions. They both received a KLEIN grant from the NWO. With these grants, NWO wants to stimulate innovative, fundamental r…

Bacteria have the ability to alter their morphology in order to adapt to changing environments.

Dennis Claessen has been appointed professor of Molecular Microbiology at the Institute of Biology Leiden. With his teaching and research on the cell wall, the professor wants to establish applications in the industry and the medical sector.

The CMCB brings together microbial cell biology expertise in Leiden. It aims at optimal resonance between the groups and maximal exploitation of the available infrastructure and to develop innovative cross-boundary technology platforms.

Atherosclerosis (thickening of the artery wall) is the most common cause of heart attacks or strokes, and one of the most common causes of death in the western world. People with this condition have to take medicine all their lives, so a vaccine for atherosclerosis would be a breakthrough.

The aim of this thesis is to study cell-cell interactions and the development of an assay to explore and quantify the exchange of membrane compounds.

Atherosclerosis is the main underlying pathology of cardiovascular disease. Atherosclerosis is caused by an immune response which is directed against (modified) lipoproteins which accumulate in the vessel wall.

Atherosclerosis is the most important underlying process that drives cardiovascular disease, and is characterized by an accumulation of cholesterol which triggers an inflammatory response in the vessel wall.

Our object is to identify and characterize transcription factors involved in lignocellulosic biomass degradation in the filamentous fungus Aspergillus niger.

Our focus is to optimize the fungal cell wall to both increase chitin production and chitin extractability.

At the Cell Observatory we visualize the dynamic structures of life - from molecule to cell to organism -with the ultimate goal to tackle disease, for instance to reduce the spread of cancer and develop new medicines for tuberculosis. The development of new medicines is one of the core efforts of Leiden…

Cardiovascular syndromes are the major cause of death in Western societies.

Decision support tool for cell therapy commercialization and business development

Leiden has a long history in the treatment of blood cell cancer. Research to find better therapies never stands still. One of the potential treatments currently being worked on is a ‘living medicine’.

BioSolar Cells is a five-year research project in which ten knowledge institutions and 45 private industries work together.

We aim to provide new insights relating to the spectacular multi-cellular life cycle of streptomycetes and other actinobacteria.

The master's specialisation From Cells to Organisms at Leiden University examines the molecular mechanisms underlying health and disease and how cells and organisms adapt to environmental factors.

What distinguishes a tumour cell from a healthy cell? Researchers are trying to answer this question as precisely as possible. Certain differences could eventually lead to new therapies.

In this project innovative technology for photovoltaics cells is developed and analysis of ecological and health related risks are explicitly accounted for.

Cardiovascular disease is a major global burden and atherosclerosis is the main underlying pathological process.

This project aims to further understand the molecular details related to the biosynthesis and function of Galf containing glycoconjugates in fungal Aspergillus spp.

This project aims to assess the risk of spread of antimicrobial resistance genes in the environment derived from currently used synthetic biology approaches in the field of drug discovery.

Cell adhesion signaling

The loss of T-cell homeostasis and tolerance towards self-antigens is the underlying cause of autoimmune and inflammatory diseases like atherosclerosis, rheumatoid arthritis or type I diabetes. Traditionally, the treatment of these diseases consisted on systemic immune suppression, which can entail…
