The first steps are made in personalised cancer vaccination strategies, which aim to induce a more specific immune response with fewer side effects. The activation of cytotoxic T cells is crucial for an effective immune response.

The Impact of Mobility and Migration in the Roman Empire assembles a series of papers on key themes in the study of Roman mobility and migration.

Language learners in higher education increasingly conduct out-of-class self-directed learning facilitated by mobile technology. This project aims to explore how university students use mobile technology for their self-directed language learning and investigate factors that influence their self-directed…

Migration and Mobility in the Early Roman Empire by Luuk de Ligt and Laurens E. Tacoma (Eds.)

A new type of tripodal squaramide-based supramolecular hydrogels is developed and studied.

During embryonic growth, cells proliferate, differentiate, and collectively migrate to form different tissues at the right position and time in the body.

Decision support tool for cell therapy commercialization and business development

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

The aim of the project is two-fold: first, to further scholarly understanding of the human dynamics that shaped the growth of Dorestad in a broader, international context; and second, to test the potential of multi-isotopic analyses on an early medieval Dutch assemblage.

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

This dissertation is a study of archaeological remains left behind by nomadic communities in the Black Desert, situated in the northeast of modern Jordan.

In a modernist interpretation of migration controls, nation states play a major role. This book challenges this interpretation by showing that comprehensive migration checks and permanent border controls appeared much earlier, in early modern dynastic states and empires, and predated nation states by…

We study cell-fate decision-making using embryonic stem cells as a model system. Stem cells integrate a large number of cues to direct their development into a great variety of cell types.

Traditional drug discovery approaches have been hampered by (in vitro) cell-culture models that poorly represent the situation in the human body.

This dissertation aims to advance understanding of amoeboid single cell migration under the influence of changing physicochemical environmental properties. The particular focus is on the relatively unknown influence of differing physical properties in the extracellular environment, such as the migratory…

Bordering Up: Regulating Mobility Through Passes, Walls and Guards

This is special issue of the journal Language & Communication. The papers of this issue delve into the multifaceted realm of (non)belonging.

On 29 June May 2022 Yujing Tan successfully defended a doctoral thesis and graduated.

In this thesis, time-lapse fluorescent microscopy plays a pivotal role in investigating functional materials within living cells as well as the migratory behaviour of neural progenitor cells.

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…

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

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.

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

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

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.

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,…

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.

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

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…

How can we promote more durable solutions to protracted refugee situations and which roles can connectivity and mobility of displaced people play to improve protection and resilience?

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 dissertation aims to explore how university students use mobile technology for their self-directed language learning and investigate factors influencing their self-directed learning with mobile technology.

Cells in our body are constantly performing small tasks, such as repairing wounds. They exert force by changing shape. But how do cells translate their shape into exerting a force in a specific direction? Experimental and theoretical Leiden physicists have now found a clue to answer this question. Cells’…

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…
