  1. 1. Regulation of human eosinophil transmigration across lung epithelium

    Författare :Lixin Liu; Uppsala universitet; []
    Nyckelord :Medical sciences; Eosinophils; regulation; migration; epithelial cells; lung; calcium; CD11b CD18; neutrophils; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Clinical Chemistry; klinisk kemi;

    Sammanfattning : Eosinophil infiltration into the lung tissues and airways is a hallmark of allergic asthma. To reach the lung lumen, eosinophils migrate across the vascular endothelium, through the interstitial matrix and across lung epithelium. LÄS MER

  2. 2. Pulmonary Drug Absorption : In vitro and in vivo investigations of drug absorption across the lung barrier and its relation to drug physicochemical properties

    Författare :Ann Tronde; Gerrit Borchard; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacy; lung; pulmonary; drug delivery; inhalation; drug transport; pharmacokinetics; absorption; bioavailability; drug metabolism; preclinical; rat; in vivo; isolated and perfused lung; Caco-2; nebulization catheter; aerosol; physicochemical; peptide; efflux; FARMACI; PHARMACY; FARMACI; Biopharmaceutics; biofarmaci;

    Sammanfattning : Although, pulmonary drug delivery is a well established means for targeting of drugs to the lungs for the treatment of respiratory diseases as well as for the systemic delivery of volatile anesthetic agents, drug absorption kinetics in the lung have not been subjected to extensive research. The main objective of this thesis was to investigate drug absorption characteristics of the lung barrier, using the isolated and perfused rat lung model and in vivo pharmacokinetic studies in rats.

  3. 3. Mechanisms of Lung Injury in a Mouse Model of Bronchopulmonary Dysplasia

    Författare :Anna Hogmalm; Göteborgs universitet; []
    Nyckelord :bronchopulmonary dysplasia; transgenic mice; inflammation; lung; interleukin-1; αvβ6 integrin; mmp-9; surfactant;

    Sammanfattning : Bronchopulmonary dysplasia (BPD) is a chronic lung disease that affects preterm infants. Increased levels of inflammatory mediators in the amniotic fluid and in the lungs of preterm infants are associated with the development of BPD. LÄS MER

  4. 4. T cells in chronic obstructive pulmonary disease

    Författare :Ester Roos-Engstrand; Anders Blomberg; Anders Bucht; Annelie F Behndig; Magnus Sköld; Claes-Göran Löfdahl; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; airway epithelium; bronchoscopy; bronchoalveolar lavage; endobronchial mucosal biopsies; inflammation; flow cytometry; T lymphocytes; CD25; CD127; FoxP3; Lung diseases; Lungsjukdomar; lungmedicin; Lung Medicine;

    Sammanfattning : Background: Tobacco smoking is the main cause of chronic obstructive pulmonary disease, COPD, but the mechanisms by which cigarette smoke induces COPD are still elusive. T lymphocytes have been implicated in the pathogenesis of the disease, but their role in the airway inflammation in COPD is not fully understood. LÄS MER

  5. 5. Activation of lung epithelial cells by group 2 mite allergens

    Författare :Camilla Österlund; Anders Bucht; Thomas Sandström; Jan Wahlström; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; group 2 mite allergens; Der p 2; Der f 2; Eur m 2; Lep d 2; airway epithelium; lungmedicin; Lung Medicine;

    Sammanfattning : Throughout many parts of the world house dust mites (HDM) are considered as a major source of indoor aeroallergens and they are powerful inducers of allergic diseases. Proteolytic HDM allergens are recognised as being able to directly activate respiratory epithelial cells and thereby actively participate in innate immune responses. LÄS MER
