  1. 11. Murine B lymphocyte growth regulation : a study of host defence factors and their mimicry by Mycoplasma arginini

    Författare :Erik Ruuth; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; B lymphocyte; growth; lymphokine; lymphokine-like; host-parasite; M. arginini; membrane acyl protein;

    Sammanfattning : Immune responses are the result of extended clonal growth and maturation of specific precursors preexisting in low frequencies. Clonal expansion is partly controlled by soluble factors, thus, their identification is essential for the understanding of the immune response regulation. LÄS MER

  3. 12. Targeting bacterial infections by using immunomodulatory host defence peptides and proteins

    Författare :Martina Kalle; Lund Dermatologi och venereologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Host dfence peptides; Sepsis; Immunomodulation; Heparin cofactor II;

    Sammanfattning : Bacterial infections and sepsis are amongst the leading causes of death worldwide. Sepsis is caused by an uncontrolled systemic host response towards an invading pathogen. Due to the engagement of various systems including cellmediated responses, the coagulation and complement cascades, treatment of sepsis remains challenging. LÄS MER

  4. 13. Mucosal receptors involved in pathogen recognition and host defence

    Författare :Majlis Svensson; immunologi och glykobiologi - MIG Avdelningen för mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; nefrologi; Urologi; nephrology; Urology; Infections; Infektioner;

    Sammanfattning : Urinary tract infection is the most common infection in man. P fimbriae are virulence factors of uro-pathogenic Escherichia coli. They are expressed by 70-90 % of acute pyelonephritis isolates and up to 100% of the most virulent isolates that cause bacteremia. LÄS MER

  5. 14. On Mechanisms Impairing Airway Host Defence in Cystic Fibrosis

    Författare :Sandra Jovic; allergologi och palliativ medicin Lungmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Cystic fibrosis is an inherited disease, caused by mutations of the cystic fibrosis transmembrane conductance regulator gene. The gene codes for a protein that serve as chloride channel. In cystic fibrosis, this protein is lacking or has a defect function resulting in a thick and sticky mucus of the airways. LÄS MER

  7. 15. The effects of exposure to microplastics and pollutants on the arthropod microbiome

    Författare :Javier Edo Varg; Richard Svanbäck; Jarone Pinhassi; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ecotoxicology; host microbiota; freshwater; anthropogenic pollution; microplastics; pesticides; pyrethroids; detergents; toxic metals; daphnids; chironomids; water boatmen; damselflies; dragonflies;

    Sammanfattning : Anthropogenic pollution is widespread across various ecosystems. This disturbance can alter the interaction between a host and its associated microbiome, with repercussions for hosts traits such as health, behavior, and host evolution. LÄS MER
