A fresh perspective-advancing fish immunotoxicology in a complex world.

Area of Science:

• Environmental toxicology
• Immunology
• Ecotoxicology
• Fish biology

Background:

• Environmental changes pose complex threats to organism and ecosystem health.
• Immune function is increasingly recognized as a dynamic mediator of these effects.
• Environmental immunotoxicology in teleost fishes is advancing towards mechanistic and integrative frameworks.

Purpose of the Study:

• To highlight knowledge gaps in environmental immunotoxicology.
• To advocate for immune function as a mechanistic lens and health indicator.
• To improve predictive risk assessments and management strategies for aquatic ecosystems.

Main Methods:

• Leveraging omics technologies for molecular insights.
• Utilizing in vivo tracking for dynamic physiological assessment.
• Employing cross-disciplinary modeling for integrative analysis.
• Focusing on teleost fish models.

Main Results:

• Identified knowledge gaps in immune mechanisms, toxicokinetics, and multi-stressor interactions.
• Advocated for immune function as a key indicator in environmental health assessments.
• Demonstrated the potential of an integrative framework for risk assessment.

Conclusions:

• Immune function is a critical factor in understanding environmental contaminant effects.
• An integrative framework enhances predictive capabilities for ecological risk.
• The field is poised for growth through technological advancements and collaboration.
