eosinophils when compared with medium alone. Interestingly, blocking the activity of cysteinyl Leukotries using antagonists inhibited eosinophil-derived ASM proliferation. Conclusions: Eosinophils enhances the proliferation of ASM cells. This role of eosinophil does not seem to depend on ASM derived ECM proteins nor on Eosinophil derived TGF-b or TNF-a. Eosinophil seems to induce ASM proliferat...
Mechanisms of eosinophil accumulation and activation in the bronchial mucosa are crucial for the pathogenesis of asthma. The location of specialized fibroblasts, myofibroblasts, beneath the bronchial basement membrane and their proximity to infiltrating eosinophils potentially enable the myofibroblasts to modulate eosinophil survival and function in asthma. The aim of this study was to investig...
Human and animal eosinophils contain a powerful neurotoxin that causes selective neuronal and axonal damage to white matter of cerebellum and spinal cord of experimental animals when injected intrathecally. This reaction is termed the "Gordon phenomenon." We purified the eosinophil-derived neurotoxin from eosinophil-rich leukocyte suspensions or eosinophil granules from four patients with vario...
BACKGROUND Although nasal polyps are one of the most frequent diseases, their etiopathogenesis remains unclear.Since eosinophils are the main inflammatory cells in the substantial proportion of nasal polyp tissues, they are considered potentially responsible for the etiopathogenesis and prognosis of the disease. Aim of this study was to investigate the relation between mucosal and peripheral eo...
Bronchial responsiveness (histamine PC20) and peripheral blood eosinophil counts were measured in 23 asthmatic subjects, of whom 14 were atopic and nine non-atopic. In the group as a whole there was an inverse correlation between baseline eosinophil count and histamine PC20 (r = -0.71; p less than 0.001). For atopic subjects a relationship between eosinophil count and histamine PC20 was observe...

BACKGROUND The objective was to characterise the process and consequences of eosinophil activation and lysis in patients with chronic eosinophilic pneumonia and to compare them with those in patients with eosinophil pulmonary infiltrates from other causes. METHODS Cells from bronchoalveolar lavage fluid of four patients with chronic eosinophilic pneumonia and four patients with eosinophilic i...
MiR-21 is one of the most up-regulated miRNAs in multiple allergic diseases associated with eosinophilia and has been shown to positively correlate with eosinophil levels. Herein, we show that miR-21 is up-regulated during IL-5-driven eosinophil differentiation from progenitor cells in vitro. Targeted ablation of miR-21 leads to reduced eosinophil progenitor cell growth. Furthermore, miR-21(-/-...
