Alternative delivery of a thermostable inactivated polio vaccine
In the near future oral polio vaccine (OPV) will be replaced by inactivated polio vaccine (IPV) as part of the eradication program of polio. For that reason, there is a need for substantial amount of safe and more affordable IPV for low-income countries. Bioneedles, which are biodegradable mini-implants,…

3D Image to Characterize and Optimize antibody-mediated antitumor immunity
Bispecific antibodies with one Fab arm binding to effector cells, such as T-cells and NK-cells, while the other Fab arm recognizing a tumor associated antigen (TAA) can be used to redirect these effector cells for tumor specific killing. Using bispecific antibodies to treat hematological cancers is…

Inverse electron demand Diels-Alder pyridazine elimination: synthetic tools for chemical immunology
The inverse electron demand Diels-Alder (IEDDA) pyridazine elimination emerged in 2013 as a new bioorthogonal reaction and constitutes a prime example of what is now known as dissociative bioorthogonal chemistry. The research described in this Thesis aims to develop synthetic strategies which enable…

Single-cell immune profiling of atherosclerosis: from omics to therapeutics
Acute cardiovascular syndromes, including myocardial infarction or stroke, are the principal cause of death in the Western society. The main underlying pathology of cardiovascular diseases is atherosclerosis, which is caused by the accumulation of lipids and inflammatory cells in the vessel wall, in…

Steering the immune system with liposomes
Liposomes – nano-sized spheres composed of fatty molecules – are very promising for vaccination. Bio-pharmaceutical scientist Naomi Benne discovered that the immune response in animal models can be steered by varying the charge of the liposomes. She obtained her PhD degree on 8 September for this research,…
