Differentiation in vitro of hybrid eosinophil/basophil granulocytes: autocrine function of an eosinophil developmental intermediate
Granulocytes with the hybrid characteristics of eosinophils and basophils have been identified in the bone marrow and peripheral blood of humans with myeloid leukemias. We now describe a technique by which such hybrid granulocytes can be developed in vitro from normal cord blood precursors cultured in the presence of recombinant human interleukin (rhIL) 3 (350 pM) and rhIL-5 (200 pM) in a plast...
متن کاملIn Vitro Effects of Budesonide on Eosinophil-Basophil Lineage Commitment
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...
متن کاملHeterogeneity of human peripheral blood eosinophil-type colonies: evidence for a common basophil-eosinophil progenitor.
We have recently shown that a proportion of previously designated human eosinophil "(Eo)-type" colonies in methylcellulose contain basophils and histamine (Denburg et al Blood 61:775, 1983). In the present studies, individual Eo-type colonies have been analyzed by cell morphology as well as by biochemical assays for histamine, Charcot-Leyden crystal protein (CLC), and eosinophil granule major b...
متن کاملMechanisms of eosinophil cytokine release.
Human eosinophils have been demonstrated to contain a multitude of cytokines and chemokines that exist pre-formed within these cells. This content of pre-formed cytokines, with diverse potential biologic activities, provides eosinophils with capabilities distinct from most other leukocytes. The localization of pre-formed cytokines within eosinophils is both within specific granules and associat...
متن کاملLigand density modulates eosinophil signaling and migration.
Eosinophils are a major component of the inflammatory response in persistent airway inflammation in asthma. The factors that determine the retention of eosinophils in the airway remain poorly understood. Elevated levels of fibronectin have been observed in the airway of patients with asthma, and the levels correlate with eosinophil numbers. To determine if fibronectin density modulates eosinoph...
