1. Maturation of humoral immune responses : Studies on the effects of antigen type, apoptosis and age
Sammanfattning : The humoral immune response is dependent on the formation of antibodies. Antibodies are produced by terminally differentiated B cells, plasma cells. Plasma cells are generated either directly from antigen challenged B cells, memory cells or from cells that have undergone the germinal center (GC) reaction. LÄS MER
2. Superantigens in group A streptococcus : gene diversity and humoral immune response
Sammanfattning : Group A streptococcus (GAS) is a strictly human pathogen that causes infections ranging from asymptomatic carriage to the highly lethal streptococcal toxic shock syndrome (STSS). GAS are classified according to the sequence of the variable 5’ end of the emm-gene that encodes the surface associated M-protein. LÄS MER
3. Local immune response in urinary tract infection : antibody-coated bacteria in human infection and studies of the cellular and humoral response to experimental infection with E. coli 06K13H1
Sammanfattning : .... LÄS MER
4. HIV-induced humoral immune response with specific relevance to IgA
Sammanfattning : Human Immunodeficiency Virus (HIV) transmission occurs primarily after hetero- and homosexual contact and across mucosal surfaces. The immune response in mucosal tissues is typified by secretory immunoglobulin A (SIgA), which is the predominant lg class in human external secretions. LÄS MER
5. Molecular studies of the humoral immune response in Hyalophora cecropia : structure, function and transcriptional regulation of three classes of immunoresponsive genes
Sammanfattning : Insects have an efficient humoral immune system, an important part of which is constituted by the antibacterial proteins, produced upon bacterial infection or wounding. In this thesis, the molecular mechanism of this immune response was investigated in the giant silkmoth Hyalophora cecropia, where a set of bacteriainducible proteins (immune proteins) had previously been characterized.
