16. Extracellular Matrix Alterations in Patients with Different Phenotypes of Asthma
Sammanfattning : AbstractAsthma is a chronic disease that affects approximately 300 million people worldwide, and the prevalence is increasing. It has become clear that asthma is a highly heterogeneous disease, with overlapping symptoms but with diverse immunopathology and clinical phenotypes. LÄS MER
17. 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
18. Mast Cell Progenitor Trafficking in Allergic Airway Inflammation
Sammanfattning : Mast cell progenitors originate from the bone marrow and migrate to the lungs via the blood. During maturation, these cells acquire granules that contain a potent array of bronchoconstrictive mediators. LÄS MER
19. The relationship between inflammation and structural changes in the airways of the lower and upper respiratory tract : Studies in patients with asthma, Sjögren's syndrome, rhinitis and children with otitis media with effusion
Sammanfattning : The pathophysiology of asthma, Sjögrens syndrome (SS), rhinitis, and otitis media with effusion (OME) in children has been extensively investigated in upper and lower respiratory tract, respectively, and shown to comprise structural changes in the airways and involvement of inflammatory cells. By comparing diseases that have bronchial hyperresponsivenses or mucosal inflammation as a common denominator, it may be possible to learn more about the mechanisms underlying inflammation in the upper and lower respiratory tract.

20. Serglycin-dependent mast cell-specific proteases and their potential interactions with Giardia intestinalis
Sammanfattning : Mast cells are located in mucosal and connective tissues throughout the body where they play important roles in immune reactions towards infections. Mast cell deficiency results in failure of clearance of the non-invasive intestinal protozoan parasite Giardia intestinalis in mice, but the mast cell-driven mechanisms remain poorly understood.
