6. NK cell recognition of herpesviruses : mechanisms of viral immune escape
Sammanfattning : Herpesviruses are ubiquitous pathogens which after an often asymptomatic infection establish lifelong latency in the host. Control of the viral infection depends on both innate and adaptive immune system. LÄS MER
7. Complement evasion strategies of human pathogens - the evolutionary arms race
Sammanfattning : Although the complement system, a pivotal component of innate immunty, is centrally involved in host defense against pathogens, its overactivation or deregulation may excessively amplify inflammation and contribute to immunopathology. Periodontitis, an oral infection-driven chronic inflammatory disease, has been linked with complement disruption by periodontal bacteria, resulting in inflammation and pathogenesis. LÄS MER
8. Mechanisms of immune escape in EBV associated malignancies : Hodgkin's disease and Burkitt's lymphoma
Sammanfattning : The work presented in this thesis is focused on the analysis of the mechanisms operating in the immune escape of two Epstein-Barr virus (EBV) associated tumors: Hodgkin's Disease (HD) and Burkitt's lymphoma (BL). EBV positive HD tumor cells express at least 3 viral proteins: the EBV nuclear antigen (EBNA)1, the latent membrane proteins (LMP)1 and LMP2A. LÄS MER
9. Myeloid-Derived Suppressor Cells and Other Immune Escape Mechanisms in Chronic Leukemia
Sammanfattning : Chronic myeloid leukemia (CML) is characterized by the Philadelphia chromosome, a minute chromosome that leads to the creation of the fusion gene BCR/ABL and the transcription of the fusion protein BCR/ABL in transformed cells. The constitutively active tyrosine kinase BCR/ABL confers enhanced proliferation and survival on leukemic cells. LÄS MER
10. Novel innate immune functions of saliva
Sammanfattning : The innate immune system in humans has succeeded in developing numerous mechanisms against the injurious effects of bacteria, along with their toxins as a result of several thousand years of co-evolution. The oral mucosal surface represents such a unique environment, where despite being constantly exposed to microbes and their products, overt infection and damage is a rarity. LÄS MER
