1. Intestinal IgA synthesis: Localization and requirements for IgA class switch recombination
Sammanfattning : Production of IgA at mucosal surfaces is one of the most striking features of the mucosal immune system. Despite that IgA was first discovered in the 1950’s and secretory IgA described in gut secretions and breast milk in the mid 1960’s we still have limited information about the sites and exact requirements for IgA class switch recombination.

2. Regulation of gut IgA induction by helper T cells
Sammanfattning : The gut is the largest lymphoid organ in the body. Due to intense and constant exposure to the outside world, it also functions as the most important portal of entry for many pathogens. LÄS MER
3. Role of DNA repair in class switch recombination and somatic hypermutation
Sammanfattning : Class switch recombination (CSR) and somatic hypermutation (SHM), occurring in the germinal center, are two important processes for B cell development. Both are initiated by activation-induced cytidine deaminase (AID), through deamination of the C residues in the variable and switch regions of the immunoglobulin locus, resulting in either in single stranded or double stranded DNA breaks.

4. Immunoglobulin isotype switching in health and disease
Sammanfattning : Immunoglobulin isotype switching is the process where the Cmy region, initially located downstream of the VDJ region is replaced by another constant region gene. Class switch recombination takes place between switch (S) regions, composed of tandem repeats of short unit sequences, located 5 of each CH gene, except for Cdelta. LÄS MER
5. Studies on Molecular Genetics of B cell Development
Sammanfattning : The development of immature progenitor cells into highly differentiated effector cells is a process central in modern medicine with applications in the fields of cell therapy as well as oncology. This thesis is focused on the molecular mechanisms that control the development of B lymphocytes. LÄS MER
