11. Studies of Rejection in Experimental Xenotransplantation
Abstract : One main hurdle to xenotransplantation, i.e. transplantation between different species, is the immunological barrier that the organ meets in the recipient. The aim of this thesis was to characterise xenogeneic rejection mechanisms by using the concordant mouse-to-rat heart transplantation model. READ MORE

12. T cells in chronic obstructive pulmonary disease
Abstract : Background: Tobacco smoking is the main cause of chronic obstructive pulmonary disease, COPD, but the mechanisms by which cigarette smoke induces COPD are still elusive. T lymphocytes have been implicated in the pathogenesis of the disease, but their role in the airway inflammation in COPD is not fully understood. READ MORE

13. An experimental study on the interaction between the neuro-endocrine and immune systems in the gastrointestinal tract
Abstract : The mucosa lining of the gastrointestinal (GI) tract is in immediate contact with food nutrients to allow a rapid and efficient digestion and absorption and at the same time protects against the incessant risk of attack from pathogenic microbes. Maintenance of normal physiological activities in the GI tract is dependent on a number of regulatory interactions between the nervous, endocrine, and immune systems, as well as environmental and genetic factors.

14. Shb and Its Homologues: Signaling in T Lymphocytes and Fibroblasts
Abstract : Stimulation of the T cell receptor (TCR) induces tyrosine phosphorylation of numerous intracellular proteins, leading to activation of the interleukin-2 (IL-2) gene in T lymphocytes. Shb is a ubiquitously expressed adapter protein, with the ability to associate with the T cell receptor and several signaling proteins in T cells, including: the TCR ζ-chain, LAT, PLC-γ1, Vav, SLP-76 and Gads.

15. Molecular and Cellular Complexity of Glioma : Highlights on the Double-Edged-Sword of Infiltration Versus Proliferation and the Involvement of T Cells
Abstract : Glioblastoma multiforme (GBM), the most common and malignant brain tumor, is characterized by high molecular and cellular heterogeneity within and among tumors. Parameters such as invasive growth, infiltration of immune cells and endothelial proliferation contribute in a systemic manner to maintain the malignancy. READ MORE
