Eosinophil Ultrastructure: Atlas of Eosinophil Cell Biology and Pathology focuses on eosinophils and their functional roles in inflammation, host defense and normal homeostatic activities. The book explores the ultrastructure of human eosinophils, highlighting biological processes observed in normal, experimental and pathological conditions. Created to fill a void in the eosinophil literature, this book has an extensive array of electron microscopic images that illustrate the diversity of eosinophil morphology. While the atlas is primarily a learning and teaching tool, it also acts as a helpful resource for researchers who want to identify distinguishing features and structural changes that arise during studies of human eosinophils.

  • Helps readers understand human eosinophils in studies focused on structural biology, cellular immunology, innate and adaptive immunity, immune responses to pathogens, immunopathology and inflammatory responses
  • Provides a core of essential knowledge to identify both immature and mature eosinophils
  • Comprises a representative compilation of the eosinophil ultrastructure during biological processes, such as activation and degranulation, observed mostly in experimental conditions
  • Highlights eosinophil biological processes found in vivo during human diseases, thus providing a link between basic science and clinical aspects
  • Helps identify distinguishing features and structural changes that arise during studies of human eosinophils in culture
