The present study was performed to investigate the early signalling events responsible for eosinophil activation in response to platelet-activating factor (PAF), C5a, and leukotriene B4 (LTB4). We evaluated the effect of pertussis toxin (PTX) on eosinophil aggregation in vitro and cutaneous eosinophil recruitment in vivo. Further studies using the protein kinase inhibitors Ro 31-8220 and stauro...
The literature on the eosinophil is vast. In the preface to this book the authors refer to a review published in 1914 which cited almost 3,000 references. That this and much subsequent work has contributed so little to our u.nderstanding of the eosinophil is largely due to the fact that techniques available to study haematogenous cells were inappropriate to the fundamental problems of their ori...
The understanding of the mechanisms underlying eosinophil recruitment in vivo may aid in the development of novel strategies for the treatment of allergic disorders. In this study, we investigated the role of chemokines in the cascade of events leading to eosinophil recruitment in a stem cell factor (SCF)- and leukotriene B(4) (LTB(4))-dependent allergic pleurisy model in mice. The intrapleural...
To determine the role of vascular cell adhesion molecule 1 (VCAM-1)/very late activation antigen 4 (VLA-4) and intercellular adhesion molecule 1 (ICAM-1)/lymphocyte function-associated antigen 1 (LFA-1) interactions in causing antigen-induced eosinophil and T cell recruitment into the tissue, we studied the effect of the in vivo blocking of VCAM-1, ICAM-1, VLA-4, and LFA-1 by pretreatment with ...
BACKGROUND We have previously demonstrated the clinical efficacy of montelukast in a randomized double-blind controlled cross-over trial in patients with dyspepsia in association with duodenal eosinophilia. The mechanism of this clinical response is unknown but could involve a decrease in eosinophil density or activation. METHODS Twenty-four dyspeptic patients 8-17 years of age underwent init...
Background Making decision on asthma as an inflammatory disease is done mostly on the airways function and the patient symptoms which most of them are nonspecific and subjective. Also, the children are not able to express their signs and collaboration in examination of the lungs function. Evaluation of serum level inflammatory biomarkers can be useful in assessment of the response to treatment ...
Post-translational Tyrosine Nitration of Eosinophil Granule Toxins Mediated by Eosinophil Peroxidase
Hematopoietins, interleukin (IL)-3, IL-5, and granulocyte/macrophage colony-stimulating factor (GM-CSF) have previously been shown to prolong eosinophil survival and abrogate apoptosis. The objective of this study was to investigate the effect of transforming growth factor beta (TGF-beta) on eosinophil survival and apoptosis. Eosinophils from peripheral blood of mildly eosinophilic donors were ...
