Title: "Discovery and characterization of nanobodies for inhibition of Hymenoptera venom allergy"
Place: Gustav Wieds Vej 10C, 8000 Aarhus C, Building 3130, Room 303.
Hymenoptera venom allergy is one of the main causes of anaphylaxis and is caused by the binding of venom allergens to receptor-bound IgE on the surface of effector cells. In my master project, I have selected and characterized nanobodies against one of the major wasp venom allergens. The selected nanobodies have the potential to block the binding of IgE to the allergen and thus prevent anaphylaxis upon exposure to the allergen.

Title: "Wireless electromagnetic neural stimulation patch with anisotropic guidance for neural regeneration”
Place: Gustav Wieds Vej 10C, 8000 Aarhus C, Building 3130, Room 303.
The human body is limited in healing neurological damage caused by diseases or traumatic injury and advanced neurological therapeutics are required to repair damaged tissue. Electrical stimulation is known to promote neural growth and differentiation. Here, a wireless electromagnetic stimulation scaffold was created for the first time, combining stimulation through electromagnetic induction with physical guiding cues through structural anisotropy. The melt electrowritten polycaprolactone anisotropic structure with 80 nm gold coating directly employed the energy harvesting component (induction coil) as the stimulation delivery interface for direct contact of cells.

Title: ”Developing organ on chip for biology and clinics”
Place: Gustav Wieds Vej 10C, 8000 Aarhus C, Building 3130, Room 303.
The development of a new generation of in vitro models is of interest in different fields such as basic research in life science to decipher physiological and patho-physiological mechanisms or in pharma companies to drastically improve drug screening process. In the last decade, basic research showed how our understanding of the behavior of physiological and patho-physiological systems can be greatly increased thanks to a rational simplification of the human body in artificial microsystems. Among these different models, organ on chips are considered today as key technologies.
In this talk, we will demonstrate how microfluidics and microfabrication can be used to develop new relevant in vitro models in particular a gut on chip model that allows to the study for the first time he interplay between, stromal and epithelial cells.
As a critical problem in the development and deployment of effective anti-cancer treatments remains the lack of adequate in-vitro model systems, in a second part, I will focus on tumor on chip development recapitulating in vitro the complexity of the tumor-microenvironment.

Title: ”Blood-Brain Barrier Models in vitro: Image Analysis of Vesicular Trafficking and 3D Growth Guidance of Brain Endothelial Cells”
Place: Gustav Wieds Vej 10C, 8000 Aarhus C, Building 3130, Room 303.
The restrictive properties of the blood brain barrier (BBB) make drug delivery to the brain challenging. Questions related to the exact route of molecular transport across the BBB remain unanswered, however transferrin receptor (TfR)-mediated transcytosis through endothelial cells is believed to be a promising target for delivering therapeutics to the brain. I will present the master thesis I’m currently working on, focusing on super resolution microscopy of vesicular transport in endothelial cells, as well as mechanical studies of human induced pluripotent stem cell-derived brain endothelial cells grown on 3D scaffolds.

Title: ”Enriching Synaptosomes for Imaging”
Place: Gustav Wieds Vej 10C, 8000 Aarhus C, Building 3130, Room 303.
Synaptosomes are isolated synaptic terminals from neurons obtained by homogenization of brain tissue followed by fractionation using Percoll density gradient centrifugation. We have found that these samples contain a variety of vesicular structures, making the search and identification of synaptosomes a challenging and time-consuming task. This presentation will be part two of my master's thesis on the use of immunomagnetic isolation for selective enrichment of synaptosomes.

Title: ”Nanobody-based inhibitors of allergen-mediated anaphylaxis”
Place: Gustav Wieds Vej 10C, 8000 Aarhus C, Building 3130, Room 303.
Hymenoptera venom allergy is one of the most common causes of anaphylaxis. Central in the allergic reaction is the binding of venom allergens to IgE/receptor complexes on the surface of effector cells triggering immediate allergic reactions and potentially anaphylaxis. In my PhD project, I have developed and characterized nanobodies and nanobody-based formats that block the IgE/allergen interaction and thereby potentially reduce the risk of anaphylaxis during allergen exposure.

Title: ”Anti-EpCAM Conjugated Melt-Electrowritten Microfibrous Filter for Capturing and Culturing Circulating Tumor Cells”
Place: Gustav Wieds Vej 10C, 8000 Aarhus C, Building 3130, Room 303.
This presentation will focus on my Master's thesis, where I am utilizing melt-electrowriting to fabricate porous filters of polycaprolactone (PCL). The fiber surface is subsequently conjugated with an anti-EpCAM antibody to allow for affinity-based capture of rare circulating tumor cells (CTCs) from a liquid biopsy, i.e. a blood sample. Due to the biocompatibility of PCL, the caught CTCs will be cultured ex vivo directly on the filter and the formed clusters may contain information useful for personalized medicine.

Title: ”Development of a targeted drug delivery system for Staphylococcus aureus biofilm infections”
Place: Gustav Wieds Vej 10C, 8000 Aarhus C, Building 3130, Room 303.
Conventional antibiotic treatment is inadequate for eradication of bacterial biofilm infections as only sublethal concentrations can be administered safely to patients. A potential solution to this challenge is targeted drug delivery.
In my PhD study, we tailored an aptamer-targeted liposomal drug delivery system that accumulates in S. aureus biofilm and delivers a combination of antibiotics locally inside the biofilm. In this presentation I will show the results and discuss what we learned from the study.

Title: ”Establishment and Characterization of Polymicrobial Inter-kingdom three-species biofilm models mimicking the microenvironment of In Vivo Chronic Wounds in Diabetic Foot Ulcers”
Place: Gustav Wieds Vej 10C, 8000 Aarhus C, Building 3130, Room 303.
Chronic wounds have become a global health problem. Chronic wounds are often infected with polymicrobial biofilms that hinders the normal healing of wounds. Consequently, chronic wounds remain in the inflammatory phase of healing. In vitro studies of chronic wounds often utilizes simple, monocultural models that exhibit unrealistic fast eradication of biofilms, once treated with antimicrobials. Given that these results are not observed in the clinic, there has become a need for more complex in vitro models comprised of multiple microbes. During my thesis, i aim to establish a polymicrobial, inter-kingdom biofilm model comprised of Staphylococcus aureus, Pseudomonas aeruginosa, and Candida albicans.
