Zebrafish: A Relevant Genetic Model for Human Primary Immunodeficiency (PID) Disorders?

Area of Science:

• Immunology
• Genetics
• Developmental Biology

Background:

• Primary immunodeficiency (PID) disorders, or inborn errors of immunity, are genetic conditions affecting immune cell function.
• Studying rare PIDs is challenging due to genetic and environmental variability, necessitating robust animal models for research.
• Zebrafish offer a conserved immune system and genetic tractability, making them suitable for PID research.

Purpose of the Study:

• To review the utility of zebrafish as a genetic model for primary immunodeficiencies.
• To highlight the conservation of the zebrafish immune system relevant to human PIDs.
• To showcase specific zebrafish models for various PID categories and their applications.

Main Methods:

• Review of existing literature on zebrafish models for PIDs.
• Analysis of immune system conservation between zebrafish and humans.
• Categorization of zebrafish PID models based on human disease types.

Main Results:

• Zebrafish possess a conserved immune system, making them relevant for studying human PIDs.
• Specific zebrafish models exist for diverse PIDs, including SCID, CID, and neutropenia.
• These models are applicable to microbiology, immunology, regenerative biology, and oncology research.

Conclusions:

• Zebrafish are a powerful and versatile model organism for investigating the mechanisms of primary immunodeficiencies.
• Zebrafish models facilitate the development of novel therapeutic strategies for inborn errors of immunity.
• The use of zebrafish advances research across multiple biomedical fields, including infectious disease and cancer.
