  2. 1. Phagolysosomal pH measurements in alveolar macrophages

    Author : Kristina Nyberg Lindborg; Karolinska Institutet; Karolinska Institutet; []
    Keywords : alveolar clearance; alveolar macrophages; phagocytosis; phagolysosomal pH; respiratory burst; silica particles; S. cerevisiae; C. albicans;

    Abstract : 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). READ MORE

  4. 2. Role of alveolar epithelial cells in macrophage responses against mycobacterial infections

    Author : Olga Daniela Chuquimia Flores; Carmen Fernández; Diana Boraschi; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Lung; alveolar epithelial cells; macrophages; AEC-derived media; control of intracellular bacterial growth; mycobacterial infections; immunologi; Immunology;

    Abstract : 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.

  5. 3. Function of B2-adrenoceptors on alveolar macrophages

    Author : Anita Zetterlund; Karolinska Institutet; Karolinska Institutet; []
    Keywords : A;

    Abstract : 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. READ MORE

  6. 4. Alveolar macrophages and lung surfactant in the defense against Cryptococcus neoformans

    Author : Norma Teresa Gross; Karolinska Institutet; Karolinska Institutet; []
    Keywords : alveolar macrophages; Cryptococcus neoformans; lung surfactant;

    Abstract : 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. READ MORE

  7. 5. Eosinophil Cationic Protein : Expression Levels and Polymorphisms

    Author : Jonas Byström; Helene Rosenberg; Uppsala universitet; []
    Keywords : Medical sciences; Eosinophils; Neutrophils; Monocytes; Macrophages; mRNA; eosinophil cationic protein; DNA; polymorphism; Hodgkin Lymphoma; asthma; allergy; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Clinical Chemistry; klinisk kemi;

    Abstract : 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. READ MORE
