Induction of Hypodense Eosinophils and Nuclear Hypersegmentation of Eosinophils by Various Chemotactic Factors and Lymphokines In Vitro
We have previously reported pulmonary eosinophils in eosinophilic pneumonia (PIE syndrome) showed two characteristics: hypodensity and nuclear hypersegmentation. Our present working hypothesis is that the eosinophil chemotactic factor and certain lymphokines may be involved in the induction of these characteristic features. Therefore, we examined whether these stimuli can induce two characteristics in vitro. Results were as follows. 1) Chemoattracts (ECF-A, histamine and PAF) can induce both nuclear hypersegmentation and hypodense eosinophils. 2) Hypodense eosinophils can be induced earlier than induction of hypersegmented nuclei (hypodense eosinophils within three hours, hypersegmented nuclei: 12 hrs). 3) Furthermore, lymphokines can not induce hypodense eosinophil. 4) However, PHA-Iymphocyte culture medium (PHALCM), -IFN and IL-3 + GM-CSF can induce hypersegmented nuclei but IL-2 has no effect on nuclear segmentation of eosinophils.

- Allergy and Asthma Proceedings is a peer reviewed publication dedicated to distributing timely scientific research regarding advancements in the knowledge and practice of allergy, asthma and immunology. Its primary readership consists of allergists and pulmonologists.
The goal of the Proceedings is to publish articles with a predominantly clinical focus which directly impact quality of care for patients with allergic disease and asthma and by having the potential to directly impact the quality of patient care. AAP welcomes the submission of original works including peer-reviewed original research and clinical trial results. Additionally, as the official journal of the Eastern Allergy Conference (EAC), AAP will publish content from EAC poster sessions as well as review articles derived from EAC lectures.
Featured topics include asthma, rhinitis, sinusitis, food allergies, allergic skin diseases, diagnostic techniques, allergens, and treatment modalities. Published material includes peer-reviewed original research, clinical trials and review articles.
Articles marked "F" offer free full text for personal noncommercial use only.
The journal is indexed in Thomson Reuters Web of Science and Science Citation Index Expanded, plus the National Library of Medicine's PubMed service. - Editorial Board
