Medical Biotechnology Seminar Lectures

Thursday 11 April 2024, at 14:00

Lecture by: Postdoc Anne-Sofie Ravn Ballegaard

Title: Is IgE a suitable target in allergy therapy?

Place: Gustav Wieds Vej 10C, 8000 Aarhus C, Building 3130, Room 303.

The antibody isotype IgE is the main player in type I hypersensitivity. Hence, targeting IgE is a major option for therapeutic intervention in allergic diseases. Available treatment forms rely merely on inhibition of the IgE binding to its receptor on effector cells. However, molecular approaches to displace IgE from its receptor on effector cells without risk of activation have been described.

In this presentation, I will give an update on the development of candidate molecules that have the capability of inhibition as well as displacement activity.

Title: "Single-cell RNA transcriptomics of cervical exfoliated cells during carcinogenesis reveals potential biomarkers”

Place: Gustav Wieds Vej 10C, 8000 Aarhus C, Building 3130, Room 303.

Cervical cancer is a prevalent gynecological malignancy despite the efficacy of various screening methods. Persistent human papillomavirus (HPV) infection is the primary cause of Cervical cancer. Understanding the multicellular ecosystem and signaling events at different stages in cervical carcinogenesis enables the identification of early detection biomarkers, which is critical for impeding the transition from low-grade cervical intraepithelial lesions to cancer. Here, I will discuss the recent study revealing potential biomarkers and cellular pathogenesis in cervical carcinogenesis using Single-cell RNA sequencing of cervical exfoliated cells.

Lecture by: Professor Peter Lindberg Nejsum

Title: Parasite extracellular vesicles show diverse functions in their host

Place: Gustav Wieds Vej 10C, 8000 Aarhus C, Building 3130, Room 303.

Helminths are parasitic worms that often cause chronic infection by releasing excretory/secretory products that modulate the host’s immune response. We, and others, have shown that extracellular vesicles (EVs) are released with the excretory/secretory products. To understand the potential role of EVs in host-parasite interaction, we have profiled their content and identified microRNAs and proteins that may be essential for parasite survival. To further understand their role, we have conducted several functional studies, and strikingly, we find that EVs may play a diverse role in host-pathogen interaction depending on parasite species. While we find that Ascaris release EVs that suppress the host immune response and are selectively internalized by monocytes, Trichuris-derived EVs did not modulate the immune response but selectively packed microRNAs in EVs that can suppress cancer genes. Other parasites release highly immunogenic EVs, suggesting a central role in pathogenicity. In conclusion, though we find that EVs are critical in host-parasite interaction their role is context and species-dependent.

Lecture by: Postdoc Kristian Juul-Madsen

Title: Amyloid-β aggregates activate peripheral monocytes in mild cognitive impairment

Place: Gustav Wieds Vej 10C, 8000 Aarhus C, Building 3130, Room 303.

The peripheral immune system is important in neurodegenerative diseases, both in protecting and inflaming the brain, but the underlying mechanisms remain elusive. Alzheimer’s Disease is commonly preceded by a prodromal period. Here, we report the presence of large Aβ aggregates in plasma from patients with mild cognitive impairment (n = 38). The aggregates are associated with low level Alzheimer’s Disease-like brain pathology as observed by 11C-PiB PET and 18F-FTP PET and lowered CD18-rich monocytes. We characterize complement receptor 4 as a strong binder of amyloids and show Aβ aggregates are preferentially phagocytosed and stimulate lysosomal activity through this receptor in stem cell-derived microglia. KIM127 integrin activation in monocytes promotes size selective phagocytosis of Aβ. Hydrodynamic calculations suggest Aβ aggregates associate with vessel walls of the cortical capillaries. In turn, we hypothesize aggregates may provide an adhesion substrate for recruiting CD18-rich monocytes into the cortex. Our results support a role for complement receptor 4 in regulating amyloid homeostasis.


Thursday 15 February 2024, at 14:00

Lecture by: Josephine Baunvig Aagaard (Postdoc in the Immunological Biotechnology group)

Title: Nanobodies for Prevention of Anaphylaxis in Honeybee Venom Allergy

Place: Gustav Wieds Vej 10C, 8000 Aarhus C, Building 3130, Room 303.

Insect venom allergy is the most common cause 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 this presentation, I will demonstrate how allergen-specific nanobody formats can block the binding of allergens and thereby prevent the subsequent allergic reaction. These findings provide the functional and structural basis for establishing a passive immunotherapy approach for protection against anaphylaxis in honeybee venom allergy.

Lecture by: Mette Steen Toftdal (Industrial Ph.D. student from the group of Nanofiber Technology and Cellular Engineering)

Title: Fighting Diabetes – Combining Beta Cell Therapy with Tissue Engineering

Place: Gustav Wieds Vej 10C, 8000 Aarhus C, Building 3130, Room 303.

Diabetes affects over 400 million people worldwide, and while cell therapy holds promise for curing Type 1 diabetes, low retention rates and inadequate cell survival remain ongoing challenges. Combining cell therapy with tissue engineering may provide a solution to these challenges. In this presentation, I will introduce a developed device for beta cell transplantation. The device, consisting of PLCL/GelMA/alginate coaxial nanofibers embedded in an alginate hydrogel, was characterized physically and mechanically, as well as analyzed for its interaction with beta cell clusters. The device shows potential for improving beta cell therapy and overcoming challenges in cell survival.

Lecture by: Postdoc Naveen Kumar Nircha

Title: "From Organoids to Organism: Unraveling the Gastroesophageal Junction Evolution Through Single-Cell and Spatial Transcriptomics”

Place: Gustav Wieds Vej 10C, 8000 Aarhus C, Building 3130, Room 303.

The gastroesophageal junction (GEJ) is a key anatomical site prone to stress-induced metaplasia and subsequent esophageal adenocarcinoma (EAC), a cancer with a notably low five-year survival rate. In our study, we utilized single-cell transcriptomics and spatial analysis to identify the cellular and molecular intricacies of the GEJ in healthy mouse tissue, spanning from embryonic to adult stages. We uncovered distinct transcriptional profiles and signaling pathways in epithelial and mesenchymal cells that are pivotal in GEJ development. Through advanced techniques like organoid models, lineage tracing, and single-molecule RNA in situ hybridization, we have further deciphered the regulatory mechanisms of squamo-columnar junctional epithelial cells in the GEJ. Our research illuminates the molecular framework of GEJ development and provides comprehensive insights into the interactions between fibroblasts and epithelial cells, enhancing our understanding of tissue heterogeneity, homeostasis, and regeneration.

Lecture by: AC-TAP Jonas Karlsen

Title: "Mystery of the bacterial HIRAN domain”

Place: Gustav Wieds Vej 10A, 8000 Aarhus C, Building 3140, Room 103.

A quick search on PubMed for HIRAN domains gives you only 28 articles, and of those only one mentions HIRAN domains found in bacteria. HIRAN domains, as we know them today, are DNA binding proteins which have so far been described as a vital part of the protein complex resolving replication fork stalling in humans. However, new studies have found domain homologs in bacteria with many unknown functions. In this presentation I will go through my thesis work on bacterial HIRAN domains as well as their presumed role in toxin anti-toxin systems.

Lecture by: Postdoc Irving Martinez Acosta

Title: "Mathematical modeling and simulation of coronary stents”

Place: Gustav Wieds Vej 10C, 8000 Aarhus C, Building 3130, Room 303.

Every year approximately 3 million people in the US suffer from atherosclerosis, which is the condition in which one or more arteries get clogged up from excessive cholesterol and other residue build up. In spite of being introduced into the market decades ago, coronary stents remain the most popular solution, given their low surgery risk. However, stents are prone to malfunction after some time, with each type having its own set of complications. The introduction of newer types of stents to resolve the problems of their predecessors comes at the expense of creating different drawbacks. To thwart the improvisational nature of stent development, we attempt to fully understand stents through rigorous mathematical theory and modeling. 

In this presentation, we illustrate domain decomposition techniques by taking into account the interplay of distinct meshed domains and lay the theoretical and numerical groundwork to model any type of stent. In particular, we emphasize the understanding and application of PDEs such as Navier-Stokes and advection-diffusion equations in the context of hemodynamics to explore the blood velocity and pressure, the concentration of solutes, and the dissipation of drug across the stented artery system.


Friday 3 November 2023, at 14.00-15.30

Lecture by: PhD student Sif Julie Friis

Title: "Towards in-silico modelling of oral device concepts: novel methods for mechanical characterization of gastrointestinal tissue”

Place: Gustav Wieds Vej 10C, 8000 Aarhus C, Building 3130, Room 303.

Delivery by oral administration is considered the simplest way to deliver most pharmaceuticals, significantly improving treatment adherence. However, macromolecular drugs cannot survive passage through the gastrointestinal (GI) tract or have limited bioavailability. Oral devices designed to deliver drugs by injection into GI tissues may constitute an interesting solution to this limitation and as an alternative to subcutaneous injection. Conversely, a knowledge gap exists on how these devices will and should interact mechanically with the GI tissue, and there is a lack of understanding of the cellular consequences.

The aim of this PhD project is to answer these questions. It is hypothesized that a reliable virtual model of the mechanics of GI tissues can be built, provided that new test methods are developed to generate mechanical data needed to fit the parameters of the constitutive models. By performing biomechanical tests on GI tissue, necessary information on needle-tissue interaction is established. From the data, constitutive relations describing the tissue behavior under needle penetration in the GI tissue is identified, thereby relating the device design to penetration depth. Further, the experimental data and the virtual model, provide knowledge on the GI tissue strain field, caused by needle penetration and accompanying fractures. From this, it is possible to predict the potential cellular consequences of the mechanical stimuli inflicted by needle penetration. The research towards virtual models is of substantial value in the early screening of device concepts and the parameter evaluation, which may help to move forward with fewer prototype iterations and in-vivo experiments.

Lecture by: Postdoc Shivesh Anand

Title: "Breaking the Silence: Biofabrication of Human Eardrum”

Place: Gustav Wieds Vej 10C, 8000 Aarhus C, Building 3130, Room 303.

It is estimated that by 2050, one in every ten people will suffer from disabling hearing loss. Perforated eardrums represent the most common injury to the human ear, often resulting in partial or complete hearing loss due to ineffective sound conduction. While microsurgical placement of autologous tissue grafts has long been considered the 'gold standard' for treating damaged eardrums, the inherent properties of these autografts can frequently impede optimal hearing restoration following recovery. Tissue engineering has emerged as a promising approach to address some of these challenges. In this seminar, I will delve into the innovative biofabrication, biomaterial, and bioreactor-driven regenerative therapies that I developed during my PhD on eardrum reconstruction at the MERLN Institute in Maastricht, Netherlands. Join me as we break the silence and explore these cutting-edge technologies!

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.

Lecture by: Stephanie Descroix

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.

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.

Lecture by: Simon Sutter Rolighed

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.

Title: "Reuterin-based biological treatment to mitigate methane emissions from pig slurry storage”

Place: Gustav Wieds Vej 10C, 8000 Aarhus C, Building 3130, Room 303.

Methane (CH4) accounts for more than 90% of farmgate greenhouse gas (GHG) emissions in pig farming, with 80% being produced during manure management. In intensive pig production, slurry is stored in manure pits under the barn floor for short term storage (1 to 6 weeks) and in outside storage tanks for longer storage periods. During this time, CH4 is emitted as a result of microbial degradation of organic substrates present in the pig feces, combined with the anaerobic conditions developed under the slurry surface, which promote the activity of methanogens. Acidification is considered a benchmark technology for mitigating CH4 emissions from stored slurry. However, there are several associated drawbacks such as safety issues in application, soil sensitivity to increased sulphur loads during land application, and inhibitory effects on biogas production. Other chemical additives raise further environmental concerns; hence the need for a biological alternative is highly sought for CH4 mitigation in slurry storage.  

Biological treatments studied thus far, utilizing microbial or enzymatic additives have shown little to insignificant potential for CH4 mitigation in pig and cattle slurry storages. In this seminar talk, we will present and discuss the results of a successful biological treatment aimed at inhibiting methanogenic activity in slurry storages, conducted on a laboratory scale headspace emission setup. The biological additive involves the use of Limosilactobacillus reuteri, which in the presence of glycerol produces reuterin, a broad-spectrum antimicrobial agent. We assessed the impact of endogenously produced reuterin on CH4 emissions from pig slurry by initially introducing both L. reuteri and glycerol into the slurry, which was then stored for a period of 26 to 30 days, during which CH4 emissions were measured. We also optimized the dosage combination of L. reuteri and glycerol. Our results showed that endogenously produced reuterin reduced CH4 emissions by 74-90% compared to untreated slurry. The environmental and biological aspect of our study will be further discussed, highlighting this novel approach as a promising alternative to H2SO4 or chemical surfactant treatments for reducing methanogenic activity in pig slurry storages.
