  1. 1. Endotoxin-induced inflammation in healthy human airways

    Författare :Margaretha E. Smith; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; LPS; neutrophils; bronchoalveolar lavage; human airways; innate immunity;

    Sammanfattning : The aim of this thesis was to investigate the innate immune response in healthy human airways in vivo after simulation of a Gram-negative infection. Intrabronchial exposure to the TLR4 agonist endotoxin was used as a model for the innate mechanisms in the immune response that are caused by cigarette smoke and by natural infection with Gram-negative bacteria.

  3. 2. The IL-23 axis and innate immunity in the airways

    Författare :Marit Stockfelt; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; IL-23; airways;

    Sammanfattning : The Interleukin-23 (IL-23) axis is a communication system that integrates innate and adaptive immunity. When triggered by microbial stimuli, antigen presenting cells can secrete the cytokine IL-23, leading to the production of IL-17 and IL-22. LÄS MER

  4. 3. Modeling nanofiber transport and deposition in human airways

    Författare :Sofie Högberg; Geoff Gibson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Sammanfattning : An understanding of the complex motion of fibrous particles is important in a wide range of areas, including inhalation toxicology, targeted drug delivery, composites manufacturing, paper making, and food processing. While the applications are diverse, the governing equations for the fiber motion may be shared. LÄS MER

  5. 4. Spatiotemporal Profiling of Human Development Using Multiplexed Imaging

    Författare :Sanem Sariyar; Emma Käller Lundberg; Burcu Ayoglu; Gunilla Westergren-Thorsson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; human development; organ development; spatial proteomics; single-cell proteomics; proliferation; immune system; mänsklig utveckling; organutveckling; spatial proteomik; single-cell proteomik; proliferation; immunsystem; Biotechnology; Bioteknologi;

    Sammanfattning : Human development is complex and intricate, where the positions of cells, expression of key markers, and cell-cell interactions contribute to the development of various organs from different germ layers and the establishment of the body axis. Therefore, understanding human development within spatial and temporal aspects is crucial. LÄS MER

  7. 5. Sound Generation and Propagation in the Human Upper Airways

    Författare :Lukas Schickhofer; Mihai Mihaescu; Anders Dahlkild; Mats Karlsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering Mechanics; Teknisk mekanik;

    Sammanfattning : The human upper airways embrace the source of phonation and affect the modulation of the voice, which is of vital importance for communication. Moreover, unwanted sounds may be generated in the upper airways due to elastic, collapsible parts that are susceptible to flow-induced vibration and resonance. LÄS MER
