The Invertebrate Immunocyte: A Complex and Versatile Model for Immunological, Developmental, and Environmental...

Area of Science:

• Comparative immunology
• Developmental biology
• Invertebrate zoology

Background:

• Comparative and developmental immunobiology knowledge has advanced significantly.
• Multi-omics research has enhanced our understanding of immune system complexity.
• Invertebrate immunocytes were previously understood mainly by morphology and basic functions like phagocytosis.

Purpose of the Study:

• To highlight the growing complexity and diverse functions of invertebrate immunocytes.
• To emphasize the impact of modern technologies like multi-omics and machine learning in this field.
• To position invertebrates as valuable models for biological research.

Main Methods:

• High-performance microscopy
• Flow cytometry
• Single-cell RNA sequencing (scRNA sequencing)
• Machine learning for complex data analysis

Main Results:

• Invertebrate immunocytes exhibit remarkable complexity and diversity.
• These cells are involved in host defense, stress response, wound healing, and organ regeneration.
• Immunocytes also play crucial roles in embryonic development, metamorphosis, and tissue homeostasis.

Conclusions:

• Invertebrate immunocytes are sophisticated entities with multifaceted functions.
• The revealed complexity challenges the view of invertebrates as simplified systems.
• Invertebrates offer sustainable and ethical models for significant biological research questions.
