11. NO Effect on Inflammatory Reaction in Extracorporeal Circulation : Ex vivo Studies
Sammanfattning : Nitric oxide (NO) is expressed in inflammatory tissues. However, NO effects are controversial in inflammation; NO is described as acting in a dose dependent manner and possess both pro-inflammatory and anti-inflammatory properties. LÄS MER
12. Identification of galectins as novel inflammatory mediators
Sammanfattning : The human neutrophils play important roles in the host defence against invading microorganisms. To eliminate bacteria or other invaders the neutrophils have to leave the bloodstream and cross the endothelium, migrate through the extracellular matrix towards the site of infection and phagocytose the prey to ultimately kill it.

13. Harnessing the immunoregulatory capacity of single-stranded oligonucleotides to modulate innate immunity
Sammanfattning : As the first line of defense, the innate immune system is exceptionally efficacious against invading pathogens but must be tightly regulated to avoid immune-related pathogenesis. Accordingly, the innate immune system recognizes highly conserved components associated with infections and damaged cells using a limited number of pattern-recognition receptors (PRRs), which are differentially expressed across cell types.

14. Mast cells: bad enemies or good friends? : A study of the effects of IgG immune complexes on mast cell biology
Sammanfattning : Mast cells are classically defined as bad enemies to human health due to their critical involvement in IgE-dependent allergy by virtue of the expression of the high affinity IgE receptor, FcgammaRI, on these cells. However, mouse mast cells also express FcgammaRIIB and FcgammaRIIIA, two receptors that bind IgG especially in the form of IgG immune complexes. LÄS MER
15. Mast cell responses to danger signals
Sammanfattning : Detecting and responding to danger is a paramount function of the immune system. Compounds heralding danger can be divided into two groups: exogenous and endogenous danger signals. LÄS MER
