Peptide immunotherapy in models of allergic airways disease
… used model allergen in mouse models of allergic airways inflammation (AAI). Trackable, T cell receptor transgenic T cells recognizing the immunodominant 323-339 peptide of OVA (pOVA) allow mechanistic investigation of PIT in response to pOVA. This thesis investigated the hypothesis that strong, …

The role of lipid laden macrophages in airways disease
Asthma is a chronic inflammatory disease of the airway and is often associated with Gastro-Oesophageal Reflux (GOR). Lipid laden macrophages (LLM) in the airway have previously been reported indicative of aspiration secondary to GOR. We hypothesised that lipid droplets from undigested or partially …

The IL-23 axis and innate immunity in the airways
… calprotectin and LL-37, in healthy human airways. Of these, only LL-37 was induced by the gram-negative bacterial stimulus endotoxin in this setting. This demonstrates the involvement of LL-37 in the innate immune response against gramnegative bacteria. Finally, we quantified cytokines …

Investigation of the proteins SPARC and HMGB1 in chronic airways disease
… a key driver of airway remodeling in chronic airways disease, and demonstrates context-dependent immunoregulatory functions. Although airway inflammation and remodeling are prominent features of asthma and chronic obstructive pulmonary disease (COPD), the role of SPARC in these conditions has …

Numerical investigation of airflow and aerosol deposition characteristics within human airways
Aerosolized drug delivery in human airways is typically used for the treatment of several pulmonary diseases. In this study, large-eddy simulation (LES) is used for the numerical investigation of the airflow and the aerosol deposition characteristics within the upper human airways. LES is performed …

Development of Vessels, Airways and Cartilage Rings: The role of T-box genes
Tbx4 and Tbx5 are two closely related genes that belong to the T-box family of transcription factor genes. Loss of Tbx4 results in absence of chorio-allantoic fusion and a failure of formation of the primary vascular plexus of the allantois leading to embryonic death at E10.5. Using a candidate …
