  1. 21. On the pathogenesis of infections associated with percutaneous osseointegrated orthopaedic implants

    Författare :Magdalena Zaborowska; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; osseointegration; amputation prosthesis; implant-associated infection; biofilm; staphylococci; extracellular vesicles; host defence; cytokines; cell death;

    Sammanfattning : Orthopaedic implants enable the restitution of locomotor function and improve the quality of life of many people. However, biomaterial-associated infection may occur due to the propensity of microorganisms to adhere and colonize implant surfaces. LÄS MER

  3. 22. Saliva: a cell suspension of epithelial cells harboring the antimicrobial peptide LL-37 and the growth factor EGF

    Författare :Alexandra Aidoukovitch; Institutionen för experimentell medicinsk vetenskap; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Saliva; Oral health; Innate immunity; Cathelicidin; LL-37; Host defense peptides; EGF; Saliva; Oral health; Innate immunity; Cathelicidin; LL-37; Host defence peptides; EGF;

    Sammanfattning : Saliva plays a crucial role in maintaining oral health through its physical and chemical properties that provide various protective functions. One of its essential components is the human host defense peptide LL-37, which is produced by immune cells and epithelial cells, and participates in the first line of defense against pathogens.

  4. 23. Potato mop-top virus: Variability, Movement and Suppression of Host Defence

    Författare :Pruthvi Balachandra Kalyandurg; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Potato mop-top virus (PMTV) causes an economically damaging disease called potato spraing. Despite being reported across the potato growing regions in the world, very little genetic variability has been reported for the virus. LÄS MER

  5. 24. The Role of Nitric Oxide in Host Defence Against Mycobacterium tuberculosis : Clinical and Experimental Studies

    Författare :Jonna Idh; Thomas Schön; Olle Stendahl; Åse Bengård Andersen; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Mycobacterium tuberculosis is the causative agent of tuberculosis (TB), responsible for significant morbidity and mortality worldwide, especially in low-income countries. Considering aggravating factors, such as HIV co-infection and emerging drug resistance, new therapeutic interventions are urgently needed. Following exposure to M. LÄS MER

  7. 25. Global Profiling of Host Cell Gene Expression During Adenovirus Infection

    Författare :Fredrik Granberg; Hongxing Zhao; Ulf Pettersson; Richard Roberts; Uppsala universitet; []
    Nyckelord :Genetic engineering; Adenovirus; Microarray; Gene expression; Host-virus interaction; Genteknik;

    Sammanfattning : To investigate mechanisms involved in virus-host interactions, global changes in host gene expression were examined during infection with adenovirus type 2 (Ad2) using cDNA microarray technology. In paper I and II, transcriptional changes in HeLa cells were investigated during the early and late phase of infection, respectively. LÄS MER
