Agrobacterium tumefaciens, a gram-negative plant pathogen belonging to the family Rhizobiaceae, is the causative agent of crown gall disease, which can affect many plant species including agronomically important ones.

Cardiovascular disease is the number one cause of death worldwide. The most important risk factor for developing this disease is high cholesterol levels in the blood.

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…

Cell-based medicinal products (CBMPs), such as CAR T cells, are highly complex biopharmaceutical products offering various treatment options for serious illnesses such as cancer or autoimmune diseases.

Fungal infections pose a significant threat to individuals with compromised immune systems and despite advancements in diagnosis and treatment, they continue to jeopardize patient’s health.

Growth hormone profiles are pulsatile and highly variable between individuals, limiting the implementation of mathemathical models to quantify an individual's secretion.

Barrier function is the natural role of the skin. The lipid matrix present in the outermost layer of the skin, the stratum corneum is important for this function.

Transplantation of labial salivary glands to the eyelids for patients with dry eye appears to give excellent results clinically.

The research described in this thesis shows that hypercholesterolemia, a well-established risk factor for atherosclerosis, can impact skin lipid pool and barrier function already at young age. In the field of atherosclerosis, we showed that the small peptide Lyp-1 can be used as a targeting molecule…

Heart failure is a major health care problem with high mortality.

Prostate cancer (PCa) is one of the most prevalent cancer in males.

The skin is our natural barrier and lipids are a key part of this barrier. In the outer skin layer, the stratum corneum (SC), lipids form a densely organized structure dependent on the composition of these lipids.

Cancer is considered the silent pandemic of the 21st century and the second leading cause of death worldwide.

Immunotherapies for cancer are an emerging class of therapeutic strategies which aim to treat cancer via augmentation of the immune system.

Inflammatory skin diseases such as psoriasis and atopic dermatitis can severely impact both the physical and social aspect of a patient’s life. Aberrant inflammatory responses are thought to be a major causative factor in these disorders, but an abundance of different factors contribute to the development…

The different kinds of cultural perspectives on health and disease of the participants are related to their knowledge, beliefs, values and practices manifested in various forms of lifestyle in Indonesia. The cultural diversity of the population is also related to differences in health behaviour.

Pancreatic ductal adenocarcinoma (PDAC) is among the cancers with the highest mortality rate, despite a relatively low incidence.

In this thesis, we have studied the potential of the zebrafish larval model in studying the ECS, as a complementary model to the existing rodent models.

Plants produce an astonishing variety of secondary metabolites (SMs) which are thought to play vital roles in the fitness of plants through ecological interactions.

Environmental challenges such as plastic pollution and biodiversity loss require extensive monitoring. Citizen science, in which members of the public participate in scientific research, has therefore become an important approach in environmental science.

In the last decades, activity-based protein profiling (ABPP) has emerged as a powerful chemical tool that may aid the ever-challenging drug discovery process.

In this thesis, I study 1) metabolic alterations in tuberculosis related to wasting syndrome in human patients as well as in rodent and fish animal models. 2) effects of the mutation of the leptin gene on cachexia and diabetes in rodent and zebrafish animal models.

The impact of the phenotypic plasticity of P. aeruginosa and the distinct CF lung microenvironments on antibiotic drug effects and resistance remains poorly understood.

Accurate prediction of the unbound drug concentration-time profile at the CNS target site is crucial for the assessment of the right drug concentration-effect relationship. PBPK models have supported the PK prediction of the CNS target sites and the translation of PK data between species and between…

This thesis focuses on amyloid proteins, a class of proteins that convert into amyloid fibrils.
