Regenerative medicine is a new way of treatment that helps impaired cells, tissues, and organs work well again. We do this by repairing, replacing, or restoring cells, tissues, and organs after damage from illness or injury. This includes treating long-term diseases such as diabetes, kidney diseases,…

A research goal for ABS is to develop miniaturized platforms for research in (stem)cell, in-vitro systems and application in clinical and preventive research. Combined with the high throughput, this development will make it possible to study the dynamics of pathogenesis in human and cellular models…

What is the most effective way to eliminate tumour cells? The DNA repair mechanism could play an important role in increasing the effectiveness of chemotherapy in the fight against cancerous cells. If we are to influence this mechanism, we need fundamental knowledge about how the mechanism works.

This project investigates the role of art in the public and academic debate on biosolar energy

This thesis focuses on two processes involved in fighting infections: metabolism and immune cell motility and navigation.

In this thesis, we have studied cell images from two types of cells, including pollen grains and the immune cells, neutrophils. These images are captured using a bright field microscope and a confocal microscope.

We aim to unravel the molecular mechanisms involved in the transformation of eukaryotic cells by Agrobacterium.

There is an urgent need for more physiologically relevant cell culture methods to guide compound selection in pre-clinical stages of the drug development pipeline.

Influenza CD8(+) T-cell epitopes are conserved amongst influenza strains and can be recognized by influenza-specific cytotoxic T-cells (CTLs), which can rapidly clear infected cells. An influenza peptide vaccine that elicits these CTLs would therefore be an alternative to current influenza vaccines,…

This report concerns itself with terrorist technical innovation, particularly with regards to terrorists’ incorporation of emerging technologies into their practices. More specifically, it investigates, through the elaboration of a theoretical learning framework, how terrorist groups can adopt the practices…

We aim to engineer streptomycetes to fully exploit their potential for natural product productions, by a rational design and evolution approach.

The group of Dr. Roxanne Kieltyka designs and synthesizes molecules that self-assemble into polymeric materials using specific non-covalent interactions. These substrates can be used for numerous applications in medicine ranging from disease detection to cell delivery depending on the (bio)molecular…

Improved molecular knowledge of the mechanisms of processes in the cell can lead to better medicines and new or advanced methods for combating diseases. Our MSc students in Life Science and Technology (LST) specifically learn to understand the molecular and structural chemical and biological aspects…

In order to gain a better insight into the basis of the rapid jasmonic acid (JA)-mediated stress response, an integrated approach using a targeted high-resolution mass spectrometry-based (HRMS) platform, was conducted to monitor the metabolism of JA using the model system of cell suspension cultures…

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…

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…

Lecture, Research Seminar Medieval and Early Modern History

This is an Erasmus+ International Credit Mobility project of Leiden University Medical Center with Boston Children’s Hospital in the USA.

Cytotoxic T-cells (CTLs) are involved in the clearance of viruses and killing of tumor cells.

The Business, Technology & Public Policy research group of the Department of Business Sciences at Leiden University focuses on investigating the dynamic interaction between 'new' technologies and various stakeholders, including consumers, employees, and businesses. Our research delves into perceptions,…

Synthetic hydrogels that mimic the natural extracellular matrix in the biophysical and biochemical cues it provides to cells are in high demand, however the cell phenotypes as they are observed in vivo in numerous cases have yet to be attained.

Human and animal cells are very complex: very different chemical processes are going on at the same time, but they are separated from each other because the cells are divided in compartments. These compartments may also have a profound effect on the potential efficacy of therapeutics, because the drug…

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…

One of the major limitations in culturing complex tissues or organs is the lack of vascularization in the cultured tissue. Development of a functional capillary bed could overcome this problem.

In our research protein translocation from Agrobacterium into yeast and plant cells is studied to obtain fundamental insights in the translocation process

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.

The Creative Intelligence & Technology master's programme (previously Media Technology) at Leiden University focuses on creative exploration as well as the understanding of science and technology.

The deeper understanding of an organism's pathology is important for developing treatments. Over centuries of systematic research, clinical researchers have demonstrated that the more information they acquire about the cellular properties and their organisation in the tissue, the better they can understand…
