1. Phagolysosomal pH measurements in alveolar macrophages
Sammanfattning : Background: Mechanical clearance of insoluble particles from the alveolar part of the lung is known to be a slow process in humans, i. e., one or several years. Particles deposited in the alveolar region are phagocytized by alveolar macrophages (AM). LÄS MER
2. Role of alveolar epithelial cells in macrophage responses against mycobacterial infections
Sammanfattning : This thesis aimed to investigate the role of alveolar epithelial cells (AEC) on immune responses against mycobacterial infections, specifically, the role of AEC in modulating macrophage functions through the secretion of broad variety of factors.In paper I, we compared murine AEC with interstitial macrophages (PuM) in their ability to take up and control mycobacterial growth and their capacity as antigen-presenting cells.

3. Function of B2-adrenoceptors on alveolar macrophages
Sammanfattning : B2-Agonists are very effective drugs for bronchodilatation, provide a rapid relief of symptoms in asthma, and are recommended as first line treatment, together with steroids. The relaxation of bronchial smooth muscles is a well-established effect of B-agonists, but their effects on inflammatory cells in the airways are less certain. LÄS MER
4. Alveolar macrophages and lung surfactant in the defense against Cryptococcus neoformans
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
5. Eosinophil Cationic Protein : Expression Levels and Polymorphisms
Sammanfattning : The eosinophil cationic protein (ECP) is usually associated with the eosinophil granulocyte. In this thesis the presence and production of this protein has been studied in two other cells. The circulating monocyte was found to contain ECP mRNA and small amounts of ECP, one thousand times less than that found in the eosinophil. LÄS MER
