The research aims to explore the evolutionary adaptability of enzymes and the impact of temperature on protein evolution pathways, using M. tuberculosis β-lactamase BlaC as the object of study. Enzymes inherently embody a delicate balance between activity and stability, and the acquisition of new enzymatic…

Triple-negative breast cancer (TNBC) is a subtype of breast cancer characterized by limited treatment options and unfavorable clinical outcomes. Therefore, the research described in this thesis focused on the exploration of novel targeted therapies for TNBC.

De wereldwijde race naar de quantumcomputer is in volle gang. Deze computer kan rekenklussen aan waarvan we nu alleen maar dromen, zoals het razendsnel vinden van eiwitten die als medicijn kunnen dienen. Leidse natuurkundigen ontdekten hoe je het Majorana-deeltje als bouwsteen voor deze quantumcomputer…

Als eersten ter wereld hebben studenten van de Leidse master Computer Science les gehad in het programmeren van een quantumcomputer. ‘Hiermee zijn eindelijk de complexe levensechte problemen van de maatschappij op te lossen.’

Ook planten maken groeihormonen aan, en kennen een proces van veroudering. Het bestuderen van de genen en de mechanismen hierachter is nuttig voor gewasveredeling en landbouw, maar ook voor medisch onderzoek. Dat stelt Remko Offringa, hoogleraar Ontwikkelingsgenetica van Planten.

Tuberculosebacteriën en andere intracellulaire pathogenen gebruiken immuuncellen als paard van Troje om zich in hun gastheer te verspreiden. Annemarie Meijer, hoogleraar immunobiologie, vertelt hoe onderzoek naar mechanismen van aangeboren immuniteit in zebravissen helpt om nieuwe behandelingsmethoden…

Onderzoeksgroepen in het Biological & Soft Matter onderzoeksprogramma ontrafelen de mechanismen in biologische processen en ontwikkelen nieuwe zachte materialen die geïnspireerd zijn door de natuur.

In vitro disease models play a fundamental role in drug research. They enable the systemic identification and validation of disease mechanisms and the discovery of possible drug targets. However, more than often, drug candidates that are identified in vitro fail in the later clinical stages of drug…

This course explores international arbitration as one of the most common methods of international dispute settlement. You will gain an in-depth understanding of international arbitration through the analysis of its role as a mechanism of dispute settlement, its institutions, the fields of law it is…

De Nobelprijs voor Natuurkunde gaat dit jaar naar onderzoek in de quantumfysica. De prijs wordt op 10 december uitgereikt in Stockholm. Natuurkundige Bas Hensen legt uit waarom dit belangrijk is en hoe zijn onderzoek in Leiden hieraan relateert.

In this thesis, we used genetically engineered mouse models and a variety of cell-culture based assays to identify genes and pathways that are involved in the development and treatment of invasive lobular carcinoma (ILC).

What are the global relationships between environmental conditions and abundance of distinct types of mycorrhizal fungi in soil and plant roots?

Lysosomal storage disorders (LSDs) are a group of orphan diseases characterized by lysosomal dysfunction or impaired lysosomal catabolism and affect collectively about 1 in 5000 live births.

The study of orchid flowers, fruits, and inflorescences is crucial due to the remarkable diversity of orchid species and their unique adaptations to pollinators and seed dispersers. However, our understanding of the evolution and development of these organs within the orchid family remains limited.

To improve cancer treatments, personalized medicine approaches have aimed to identify exactly which mutations are driving tumor development in a given patient and specifically target these mutations using precision therapies.

The electrochemical oxygen reduction reaction (ORR) is an essential half-reaction for the utilization of hydrogen as a sustainable fuel, via the conversion of hydrogen to electrons and protons facilitated by the ORR. In the most common fuel cells, the ORR is requires high loadings of non-abundant platinum…

As a contribution to the changing legislation and evolving societal attitudes concerning environmental issues, this project aims to enhance and manipulate the plants’ own natural defense mechanisms against western flower thrips (WFT).

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

Om de juiste klinische beslissingen te nemen of effectieve diagnostische testen en behandelingen te kunnen ontwikkelen, is het belangrijk om de onderliggende mechanismen van een aandoening of een bepaald gedrag te begrijpen.

Soil is a home for an unbelievable diversity and abundance of microbial life that is essential for supporting life on our planet.

In analogy to mathematical proofs, the goal of a proof system is for a prover to convince a verifier of the correctness of a claim.

The research presented in this thesis makes use of small molecules (as H2 , D2 and O2 ) on well-defined single crystal surfaces (flat Pt(111), flat Cu(211) and curved Pt(111)) to elucidate the role of surface structure and degrees of freedom in the reactant in specific surface reactions.

Breeding for resistance becomes more and more important because we want to reduce the use of pesticides. A fast and cheap alternative can be to make use of morphological or chemical markers.

In this thesis, mathematical modeling and simulation was applied as a tool to inform quantitative decision making in oncology drug discovery and development.

Op welke manieren hebben ontwikkeling van digitale technologieën invloed op de samenleving en de regulerings- en juridische kaders binnen de samenleving?

The PID-directed shift in PIN polarity has been broadly accepted as one of the essential mechanisms for the regulation of auxin transport polarity.
