16. Cell-mediated immunity to flavivirus infections
Sammanfattning : NK cells and T cells constitute a major part of the cell-mediated immune system and play important roles in the host defense against viral infections. Most current knowledge of cell-mediated immune responses to primary acute viral infections comes from murine models, while relatively less is known about human responses to, in particular, acute viral infections.

17. Spotted Fever Rickettsioses in Sweden : Aspects of Epidemiology, Clinical Manifestations and Co-infections
Sammanfattning : The spotted fever group rickettsiae are emerging diseases. They cause damage in their hosts by invading the endothelium in small to medium-sized blood vessels, which results in vasculitis that can cause clinical manifestations from most organs. LÄS MER
18. Diagnosis in aseptic meningitis and immune response in herpes simplex virus infections
Sammanfattning : Herpes simplex virus type 1 and 2 are ubiquitous and appear often asymptomatic but some individuals suffer from recurrent infections and the causes are largely unknown. In this thesis I present results from evaluations of diagnostic and etiologic studies of methods used for the detection of acute aseptic meningitis (AAM) and in HSV-2 meningitis in particular.

19. Genetic vaccination against acute viral disease
Sammanfattning : This thesis describes the development of recombinant vaccines based on the Semliki Forest virus (SFV) expression system. Immunisation of mice with recombinant virus particles, a layered DNA/RNA plasmid vector, and recombinant self-replicating RNA were carried out and the protective effect of these recombinant vaccines against viral challenge were examined.

20. The role of the type I interferons and viperin during neurotropic flavivirus infection
Sammanfattning : Flaviviruses are globally distributed pathogens that cause millions of human infections annually. One of the most detrimental outcomes of flavivirus infection is encephalitis, which is caused by neurotropic flaviviruses such as West Nile virus (WNV), Japanese encephalitis virus (JEV), and Tick-borne encephalitis virus (TBEV).
