1. Regulation of growth, differentiation and survival of B-chronic lymphocytic leukemia cells
Sammanfattning : Chronic lymphocytic leukemia of B cell type (B-CLL) is the most commonform of leukemia in the Western countries. The signals regulating theexpansion of the B-CLL clone in vivo is yet far from being fully understood. LÄS MER
2. Early events of EBV mediated B cell transformation
Sammanfattning : Epstein-Barr virus (EBV) efficiently immortalizes B cells in vitro leading to the establishment of lymphoblastoid cell lines (LCLs). Genes encoding RB and p53 are frequently deleted or mutated in human tumors. EBV immortalized LCLs, however, retain both genes in their wild type state. LÄS MER
3. Regulation of germline transcription in the immunoglobulin heavy chain locus
Sammanfattning : During an immune response, activated B cells develop into high rate immunoglobulin (Ig) secreting plasma cells. They also switch from production of IgM to IgG, IgA or IgE. Specific isotypes of antibodies have functional and structural features that make them particularly well suited to defend against different types of pathogens. LÄS MER
