Neutrophil-specific granule deficiency is a disorder of leukocyte maturation associated with decreased levels of mRNA for a distinct subset of granule proteins. Our work indicates that this disorder, previously thought to be limited to the neutrophil lineage, can also include eosinophils. Immunofluorescence staining led to the discovery of a small but distinct population of peripheral white blo...
Nonadherent spleen cells of mice infected with Trichinella spiralis released growth stimulatory factors (GSFs) in vitro when challenged with excretory/secretory products of muscle stage larvae. The assay of GSF was based on proliferation of normal, nonadherent syngeneic marrow cells in liquid tube cultures. Media conditioned for 1 day by challenged spleen cells stimulated eosinophil production ...
Bone marrow cultures have been established from mice infected with Mesocestoides corti and undergoing parasitic eosinophilia. In the absence of added conditioned medium, eosinophil differentiation ceases, and eosinophils are undetectable by 7 days, whereas neutrophil production continues over several weeks as with normal bone marrow. Eosinophil production can be induced by adding pokeweed mitog...
We investigated the mechanisms by which leukotriene receptor antagonists decrease airway eosinophil number. In a randomized, double blind, cross-over study, we examined the effects of two weeks of treatment with pranlukast 300 mg b.i.d. or placebo on allergen-induced changes in airway eosinophil number and bone marrow eosinophil progenitors in 15 subjects with mild asthma. Pranlukast treatment ...
Abstract Aberrancies in eosinophil proliferation, activation and chemotaxis can lead to acute eosinophilic leukemia, paraneoplastic eosinophilia associated with T cell lymphoma carcinomas, Hypereosinophilic Syndrome (HES), respectively. HES is an idiopathic disease affecting humans veterinary patients characterized by persistent (>1,500 cells/uL) infiltration of solid organs leading incr...
The adhesion of eosinophils to nerve cells and the subsequent release of eosinophil products may contribute to the pathogenesis of conditions such as asthma and inflammatory bowel disease. In this study we have separately examined the consequences of eosinophil adhesion and degranulation for nerve cell morphology and development. Eosinophils induced neurite retraction of cultured guinea pig par...
The effect of pranlukast on allergen-induced bone marrow eosinophilopoiesis in subjects with asthma.
We investigated the mechanisms by which leukotriene receptor antagonists decrease airway eosinophil number. In a randomized, double-blind crossover study, we examined the effects of 2 weeks of treatment with pranlukast 300 mg twice a day or placebo on allergen-induced changes in airway eosinophil number and bone marrow eosinophil progenitors in 15 subjects with mild asthma. Pranlukast treatment...
UNLABELLED IL-5 is the primary cytokine that stimulates the production and survival of eosinophils and basophils from progenitor cells. The inhaled glucocorticoid, budesonide, has been shown to exert a therapeutic effect via suppression of eosinophil/basophil progenitors in vivo. Since various steroids have exhibited the ability to enhance eosinophil/basophil progenitor differentiation, we exam...
Mounting evidence suggests that lipopolysaccharide (LPS) modulates bronchoconstriction and eosinophil function in asthma. We have investigated the role of different chemokines in the eosinophil influx to the pleural cavity after LPS stimulation. Expression of mRNA for eotaxin, regulated on activation, normal T cells expressed and secreted (RANTES), macrophage inflammatory protein (MIP)-1alpha, ...
