  1. 6. The influence of quartz and surfactant on immune responses

    Författare :Göran Zetterberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :alveolar macrophages; complement receptor 1 and 3; interstitial macrophages; Iysophosphatidylcholine; phospholipids; quartz; rats; receptor expression; surfactant.;

    Sammanfattning : Pulmonary surfactant is a mixture of lipids and proteins that embeds the alveolar cells, has surface tension reducing properties but also influences the immune response. To further investigate this, quartz was used to initiate an inflammatory response in two different models. LÄS MER

  3. 7. Alveolar macrophages and lung surfactant in the defense against Cryptococcus neoformans

    Författare :Norma Teresa Gross; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :alveolar macrophages; Cryptococcus neoformans; lung surfactant;

    Sammanfattning : Cryptococcus neoformans causes disease mainly in immunosuppressed patients, especially those with AIDS, and on corticosteroids. The yeast is normally inhaled and the lung is the primary site of infection, where the alveolar macrophages (AM) provide a first line of host defense. LÄS MER

  4. 8. Experimental studies on effects of orthodontic forces in generation of immune responses : possible roles for immunoregulating molecules in the control of alveolar bone remodeling

    Författare :Najat AL-Sayed AL-Hashimi; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Orthodontic forces; inflammation; immune responses; cytokines; chemokines.;

    Sammanfattning : The transformation of orthodontic forces to periodontal tissues involves several biological mechanisms, which ultimately result in bone remodelling. It has been suggested that the immune system plays a role in the regulation of bone remodelling through production of immune mediators by inflammatory cells that have migrated from dilated periodontal ligament capillaries after the application of orthodontic force.

  5. 9. Immune responses in defined subgroups of patients with pulmonary sarcoidosis

    Författare :Farah Idali; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Sarcoidosis; Löfgren s syndrome; cytokine; regulatory T cell; TIM molecule; TLR;

    Sammanfattning : This thesis focuses on inflammatory responses in the airways of sarcoidosis patients. Sarcoidosis is a T helper 1-mediated inflammatory disease with unknown aetiology. HLA-DRB1*0301pos sarcoidosis patients often present with an acute form of disease, i.e. LÄS MER

  7. 10. Immune regulation during pulmonary TB and during M. tuberculosis/HIV-1 co-infection

    Författare :Chaniya Leepiyasakulchai; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Individually, tuberculosis (TB) and acquired immunodeficiency syndrome (AIDS) pose major global health problems and together, they form a deadly liaison. Preventive vaccines for any of the diseases are not yet available. LÄS MER
