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.

Although nanoparticles are extensively used in various applications like consumer products and have most probably entered the environment, little is known about the effects of these particles on living organisms.

Assessing the risks of engineered nanomaterials (ENMs) solely on the basis of experimental assays is time-consuming, resource intensive, and constrained by ethical considerations (such as the principles of the 3Rs of animal testing). The adoption of computational toxicology in this field is a high p…

This thesis focuses on using liposomes in two different treatment strategies; vaccination (or immunotherapy) and delivery of a small molecule, and in two different disease models; cancer and atherosclerosis.

In this thesis we explore machine and deep learning approaches that address keychallenges in high dimensional problem areas and also in improving accuracy in wellknown problems. In high dimensional contexts, we have focused on computational fluid dynamics (CFD) simulations.

Atherosclerosis is a progressive disease resulting in the formation of an arterial plaque. Despite lipid lowering, recurrent cardiovascular events remain a risk. While atherosclerosis is primarily lipid-driven, the immune system plays a critical role in the pathophysiology.

This thesis describes the Multi-site All-Sky CAmeRA (MASCARA), which consists of two small robotic telescope designed to detect exoplanets around the brightest stars in the sky.

Lipid nanoparticles (LNPs) have enabled the success of mRNA vaccines but remain limited in broader therapeutic use by challenges in delivery efficiency, targeting, and mechanistic understanding.

Medewerkers en studenten van Leiden University College (LUC) werken in Den Haag samen met maatschappelijke partners via onderzoek, onderwijs, stages en vrijwilligerswerk, waardoor er sterke banden ontstaan die ook na het afstuderen blijven bestaan.

Vind jouw thuis bij LUC! Wij zijn gevestigd in het hart van Den Haag. Met ons eigen gebouw en internationale profiel biedt LUC een omgeving voor iedereen die op zoek is naar een interculturele ervaring en die een verantwoordelijke wereldburger wil worden.

Elk jaar organiseert het Global Transformations and Governance Challenges-programma een conferentie die academici en beleidsmakers samenbrengt.

In deze bundel wordt verslag gedaan van onderzoek op het gebied van duurzaamheid, uitgevoerd aan de Leidse rechtenfaculteit.

Women Writing Mexico (WWM) is a network of women and men concerned with the human rights crisis in Mexico and more specifically, with the impact of structural forms of poverty, everyday violence, and discrimination based on gender, race, social class, and ethnicity, that particularly have an impact…

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…

Hoe meer we leren over een (neuro-)psychologische of lichamelijke aandoening en de hieraan gerelateerde gedragsfactoren, hoe beter we deze niet alleen kunnen signaleren, maar ook behandelen. Het is dus belangrijk dat recente inzichten over (neuro-)psychologische problemen en daaraan gerelateerde gedragsfactoren…

Als een nieuwe methode is ontwikkeld om een (neuro-)psychologische aandoening of hieraan gerelateerde gedragsfactoren te herkennen en te behandelen, kan deze nog niet direct in de klinische praktijk worden ingezet. Eerst moet de methode geëvalueerd worden, bij voorkeur in gerandomiseerde, gecontroleerde…

Electrons in a crystal lattice have properties that may differ from those of a free electron in vacuum.

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…
