Influenza T-cell epitope-loaded virosomes adjuvanted with CpG as a potential influenza vaccine
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,…

Amphiphile Nanoparticles Enhance the Immune Response Against a CpG-Adjuvanted Influenza Antigen
Cationic peptide amphiphile nanoparticles are employed for co-delivery of immune modulator CpG and antigen. This results in better targeting to the antigen presenting cells and eliciting strong Th1 response, which is effective against the intracellular pathogens.

liposomes loaded with a synthetic long Peptide and poly(i:C): a defined adjuvanted vaccine for induction of antigen-specific T cell cytotoxicity
For effective cancer immunotherapy by vaccination, co-delivery of tumour antigens and adjuvants to dendritic cells and subsequent activation of antigen-specific cytotoxic T cells (CTLs) is crucial. In this study, a synthetic long peptide (SLP) harbouring the model CTL epitope SIINFEKL was encapsulated…

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,…

Poly-(lactic-co-glycolic-acid)-based particulate vaccines: particle uptake by dendritic cells is a key parameter for immune activation
Poly(lactic-co-glycolic acid) (PLGA) particles have been extensively studied as biodegradable delivery system to improve the potency and safety of protein-based vaccines. In this study we analyzed how the size of PLGA particles, and hence their ability to be engulfed by dendritic cells (DC), affects…

Combatting infectious diseases; nanotechnology as a platform for rational vaccine design
Currently, several successful vaccines are available. However, for pathogens with a highly variable genetic composition, and for which serum IgG antibodies are not a useful correlate of protection, effective vaccines are yet to be developed.

Intradermal delivery of nanoparticulate vaccines using coated and hollow microneedles
In summary, the collective results described in this thesis show that nanoparticulate vaccines can be delivered intradermally by coated and hollow microneedles and evoke antigen-specific immune responses.

Improved storage stability and immunogenicity of hepatitis B vaccine after spray-freeze drying in presence of sugars
The current hepatitis B vaccines need to be stored and transported under refrigerated conditions (2-8 degrees C). This dependence on a cold-chain is highly challenging in areas where hepatitis B virus infections are endemic.

Buccal and sublingual vaccine delivery
Because of their large surface area and immunological competence, mucosal tissues are attractive administration and target sites for vaccination.

One step closer to pain-free vaccinations
Microneedles are a promising tool for the painless administration of vaccines through the skin. But, are these minuscule needles really effective? PhD student Pim Schipper of the Leiden Academic Centre for Drug Research investigated various factors of vaccination via the skin and discovered, among other…

Minipigs as an Animal Model for Dermal Vaccine Delivery
Appropriate animal models for intradermal vaccine delivery are scarce. Given the high similarity of their skin anatomy to that of humans, minipigs may be a suitable model for dermal vaccine delivery.

Development of an intradermal tuberculosis vaccine by combining dissolvable microneedle arrays and Mycobacterium tuberculosis antigen-containing
Mycobacterium tuberculosis (Mtb), the pathogen causing tuberculosis (TB), is the leader among all pathogens responsible for the most human deaths today and it is considered as one of the top 10 causes of death worldwide. There is an increasing occurrence of multidrug-resistant and even totally drug-resistant…

Vaccination and Targeted Therapy Using Liposomes; Opportunities for Treatment of Atherosclerosis and Cancer
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.

CD40-targeted dendritic cell delivery of PLGA-nanoparticle vaccines induce potent anti-tumor responses
Dendritic cells (DC) play a prominent role in the priming of CD8(+) T cells. Vaccination is a promising treatment to boost tumor-specific CD8(+) T cells which is crucially dependent on adequate delivery of the vaccine to DC.

RESTORING T-CELL HOMEOSTASIS BY IN VIVO MANIPULATION OF DENDRITIC CELLS
The loss of T-cell homeostasis and tolerance towards self-antigens is the underlying cause of autoimmune and inflammatory diseases like atherosclerosis, rheumatoid arthritis or type I diabetes. Traditionally, the treatment of these diseases consisted on systemic immune suppression, which can entail…

Formulation and Characterization of Vaccines
Vaccines are an extraordinary category of biopharmaceuticals. They are usually prophylactic and come in many types, from whole bacteria to peptides and nucleic acids. They are very cost effective and almost every human on the planet is vaccinated. The latter mandates that vaccines have to be extremely…

Skin Barrier and Vaccination
The Skin Barrier and Vaccination group is led by Prof. Joke Bouwstra. One of the key functions of the skin is its barrier function, which is located in the uppermost layer of the skin, the stratum corneum. The stratum corneum consists of enucleated dead cells (corneocytes) embedded in a lipid matrix.…
