1. Interferons in immunity to chlamydia pneumoniae
Abstract : The cytokine IFN-gamma is the architect behind an amazing immunological program of host resistance to intracellular bacterial and protozoan infections. IFN-gamma activates macrophages, making them into inhospitable habitats for parasites attempting to grow inside them. READ MORE

2. Studies of the recognition and activation of natural killer cells
Abstract : Natural killer (NK) cells mediate part of the innate immune response that impedes the spread of invading microorganisms and shapes the downstream adaptive immune response. NK cells spontaneously kill tumor cells and other cells upon contact. Killing requires engagement of germline encoded receptors that mediate positive and negative signals. READ MORE

3. Experimental Chagas disease
Abstract : The main focus of this thesis was to develop and utilise experimental models using the protozoan parasite Trypanosoma cruzi. We were especially interested in studying the activation of NK cells early after T. cruzi infection and what factors that predispose to a chronic inflammatory disease after T. cruzi infection.

4. Host control of intracellular bacterial infections
Abstract : In this thesis various immune mechanisms regulating control of infections with the intracellular bacteria Listeria monocytogenes and Chlamydia pneumoniae have been studied. These bacteria infect macrophages in which they can successfully grow. However, macrophages are potent killers of intracellular bacteria. READ MORE

5. Immune regulation of herpes simplex virus type 2 infection: Special emphasis on the transcription factor T-bet
Abstract : Herpes simplex virus type 2 (HSV-2) is a sexually transmitted pathogen that infects the genital tract mucosa as well as local sensory neurons. It is the most common cause of genital ulcer disease in humans. The infection gives rise to a wide range of symptoms, ranging from severe and painful recurrent episodes of genital herpes to silent infection. READ MORE
