1. Mechanisms triggering the recruitment of mast cell progenitors to the lung and regulation of mast cell degranulation
Sammanfattning : Mast cells stem from the bone marrow and migrate via the blood as mast cell progenitors. Upon arrival in peripheral tissues, they develop into mast cells. These rare immune cells have numerous granules that contain large amounts of pro-inflammatory mediators. LÄS MER
2. 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
3. Assessment of eosinophil degranulation in allergic diseases and experimental models
Sammanfattning : In allergic disorders, the eosinophilic granulocytes migrate to affected tissues and release granule proteins with cytotoxic, immunoregulatory, and remodeling-promoting properties. Given that degranulation is reflected by a loss in eosinophil granule density of living cells, or by cell membrane rupture and release of intact granules, these morphological changes may represent a biomarker of the allergic disease.

4. Human eosinophils and their activation by allergens via danger signal receptors
Sammanfattning : Human eosinophilic granulocytes are polymorphonuclear cells with a powerful arsenal of cytotoxic substances in their granules, which are mainly found in the gastrointestinal mucosa, and the respiratory and genitourinary tracts. Their physiological role is incompletely understood, although it is likely they protect the mucosal surfaces, perhaps by recognizing danger signals present on microorganisms or released from damaged tissue.

5. A novel principle for immunomodulator delivery with hematopoietic cells as vehicles Focus on soluble TNF-receptor gene expression, targeting to secretory lysosomes and regulated secretion
Sammanfattning : The goal of this research is to use hematopoietic cells as vehicles for targeting transgenic immunomodulators to the inflammatory sites. The work presented was focused on the anti-inflammatory soluble TNF receptor. A transmembrane soluble TNF receptor (sTNFR1) construct was expressed in hematopoietic cell lines. LÄS MER
