Advancing veterinary vaccines design through trained immunity insights

Area of Science:

• Veterinary immunology
• Infectious disease control
• Vaccinology

Background:

• Trained immunity involves long-term functional reprogramming of innate immune cells.
• It presents a promising avenue for advancing veterinary vaccine development.
• Understanding its mechanisms is crucial for novel vaccine design.

Purpose of the Study:

• To examine the integration of trained immunity into veterinary vaccine design.
• To explore metabolic reprogramming and epigenetic modifications for enhanced immune responses.
• To propose strategic approaches for optimizing trained immunity-based vaccines.

Main Methods:

• Analysis of molecular mechanisms, including aerobic glycolysis and epigenetic changes.
• Review of strategic approaches for vaccine optimization.
• Consideration of challenges and potential benefits of trained immunity in veterinary settings.

Main Results:

• Trained immunity enhances immune responses through metabolic and epigenetic reprogramming.
• Effective inducers, adjuvants, and synergistic strategies are key for optimization.
• Potential for broader protection against emerging and zoonotic pathogens.

Conclusions:

• Trained immunity-based veterinary vaccines offer enhanced efficacy and cross-protection.
• This approach could revolutionize veterinary vaccinology, especially for zoonotic disease control.
• Addressing implementation challenges is vital for successful application.
