16. T-cell responses to Helicobacter pylori in humans and a possible role of regulatory T cells
Abstract : Helicobacter pylori colonize the stomach and areas of gastric metaplasia in the duodenum. The bacteria induce both local and systemic immune responses, but despite this, the infection normally persists for life and causes chronic gastritis in all infected subjects and peptic ulcers or gastric cancer in 10-20% of infected individuals.

17. Adoptive T Cell Therapy of Viral Infection and Cancer : Ex vivo Expansion of Cytomegalovirus- and Prostate Antigen-specific T Cells
Abstract : The main focus of my thesis has been to develop protocols for generating antigen-specific cytotoxic T lymphocytes (CTLs) and T helper cells (TH) for adoptive transfer to treat cytomegalovirus (CMV) disease and prostate cancer. CMV viremia is a severe complication in immunocompromised stem cell transplanted patients. READ MORE

18. 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

19. Transcriptional control of CD4+ T lymphocytes
Abstract : The immune system can respond to various types of pathogens such as bacteria, viruses, tumors and parasites. The ability to provide protection against different types of pathogens partly relies on development of alternative T effector cells with separate effector functions. READ MORE

20. Extrathymic T cell receptor gene rearrangement in human alimentary tract
Abstract : T lymphocytes regulate the initiation, duration, and magnitude of adaptive immune responses and function as effector cells in cell mediated immunity. To become immunologically competent they must generate functional antigen receptors. This process takes place in the thymus and requires somatic recombination of T cell receptor (TCR) genes. READ MORE
