1. Immunity to Salmonella infection
Abstract : The immune system has several strategies to combat infections. The present study investigates various aspects of the interaction between Gram negative bacteria, particularly Salmonella, and antigen presenting cells (APC). Salmonella is an intracellular bacterium infecting mice and man. READ MORE

2. Translational regulation of genes in salmonella typhimurium by vitamin B12
Abstract : In this thesis I have studied the mechanism by which vitamin B12 regulates the expression of the cob operon and the btuB gene in Salmonella typhimurium. The cob operon encodes most of the 25 genes required for the de novo synthesis of vitamin B12, and the butB gene encodes the outer membrane protein needed for transport of exogenous vitamin B12 into the cell.

3. Formation of Thiolated Nucleosides in tRNA in Salmonella enterica serovar typhimurium
Abstract : The presence and synthesis of transfer RNA (tRNA) is highly conserved in all organisms and a lot of genetic material is dedicated to its synthesis. tRNA contains a large number of modified nucleosides and several diverse functions have been found but much about their function is still unknown.

4. Presentation of Salmonella antigens by dendritic cells
Abstract : This study investigates the interaction between dendritic cells (DC) and the Gram negative intracellular bacterium Salmonella typhimurium. Using in vitro and in vivo approaches, the capacity of DC to directly and indirectly present antigens from Salmonella-infected cells, cytokine production by infected DC, and activation of bacteria-specific T cells was analyzed.
