Refining the DC-targeting vaccination for preventing emerging infectious diseases

Area of Science:

• Vaccinology
• Immunology
• Computational Biology

Background:

• Developing safe and effective vaccines for infectious diseases remains a significant challenge.
• Emerging and reemerging pathogens necessitate rapid and effective vaccine development strategies.
• Targeting antigens directly to dendritic cells (DCs) is a promising approach to enhance vaccine-induced immune responses.

Purpose of the Study:

• To review advancements in dendritic cell (DC) vaccination strategies.
• To highlight the role of DC-targeting vaccines and epitope mapping in improving vaccine efficacy.
• To propose a framework for enhancing vaccine responses against infectious diseases.

Main Methods:

• Review of current literature on DC vaccination and antigen targeting.
• Discussion of epitope mapping strategies using *in silico* approaches.
• Analysis of antibody-mediated antigen delivery to DC surface receptors (e.g., CD40).

Main Results:

• DC targeting vaccines enhance antigen presentation and subsequent T- and B-cell responses.
• *In silico* epitope mapping aids in selecting immunogenic and conserved epitopes.
• Fusion of antigens to monoclonal antibodies against DC receptors optimizes targeted delivery.

Conclusions:

• DC-targeting vaccines represent a significant advancement in vaccine development.
• Epitope mapping is essential for designing potent and broadly protective vaccines.
• This review provides a framework for improving vaccine efficacy against infectious diseases through targeted antigen delivery and rational epitope selection.
