    Sammanfattning : Urinary tract infection (UTI) is among the most common bacterial infections in humans and the majority are caused by Escherichia coli (E. coli). Abundant evidence indicates that nitric oxide (NO) produced by the inducible NO synthase (iNOS) plays an important role in host defense against infection. LÄS MER

  2. 2. Tartrate resistant acid phosphatase in the immune and nervous system : distribution and pathophysiological implications

    Författare :Pernilla Lång; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Tartrate resistant acid phosphatase (TRAP) belongs to the family of purple acid phosphatases (PAP). It is a glycoprotein synthesized as a monomer with low enzyme activity containing a redox active diiron centre in the active site. Post-translational proteolytic processing of this monomer into a dimeric protein increases the enzyme activity. LÄS MER

  3. 3. Leukotrienes and leukotriene receptors : potential roles in cardiovascular diseases

    Författare :Hong Qiu; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Leukotrienes (LTs) are a family of lipid mediators that are involved in host defense and inflammatory responses. They are synthesized from arachidonic acid through the 5-lipoxygenase (5-LO) pathway, and are divided into two classes, the classical chemoattractant leukotriene B4 (LTB4), and spasmogenic cysteinyl leukotrienes (cys-Us) including LTC4, LTD4 and LTE4.

  4. 4. Occupational exposure alters innate and adaptive immune responses

    Författare :Karin Sahlander; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The farming environment is contaminated with high levels of organic dust. Especially pig barn facilities are highly polluted with airborne inhalable organic dust containing high amounts of molecular patterns from bacteria and fungi known to activate cells of the innate immunity through pattern recognition receptors (PRRs).
