The cellular metabolism of immune cells constitutes an important part of their proper function and activation. Using T cells as an example, this phenomenon is highlighted by the metabolic reprogramming that occurs in these cells upon activation.

The Politics and Governance department of the Institute of Public Administration focuses on the complex interaction between politics and governance. Our research explores contemporary issues such as the impact of global crises, populism, and polarisation at various levels of government.

Climate change is a challenge for both current and future generations. New biological resources have to be developed in order to meet the demand for energy as well as the demand for food.

In films kunnen de meest wonderlijke acties plaatsvinden. Maar zijn die acties in de 'echte' wereld ook mogelijk? En in hoeverre houden filmmakers ons voor de gek? Tijdens het Leiden International Film Festival komen film en wetenschap samen.

Microbial rhodopsins are photosensitive pigments implemented in the growth and adaptation of a large population of microorganisms.

As a virtually inexhaustible source, solar energy plays a major role in future global energy scenarios.

Intrigued by the way cells autonomously regulate their fate, we strive to understand and visualize cellular processes as the basis of Cell Signaling.

Decentralized plug and play systems for energy production are the future picture of our society. Artificial photosynthetic systems are used for this purpose.

This research evaluates the Youth Act. It will provide an overview of how the transition takes place, whether the transformation process develops in the right direction and whether the legal safeguards are functioning properly.

The key questions posed in this dissertation centre on the interaction between spectator and artwork. What happens between a spectator and an artwork? How do we experience ‘meaning’ in an artwork? How may the process of interpretation be understood and articulated?

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.
