Area of Science:

• Biomaterials Science
• Immunology
• Nanotechnology

Background:

• Vaccine development faces challenges with antigen instability and suboptimal immune activation.
• Existing adjuvants have limitations in efficacy and safety.

Purpose of the Study:

• To review the role of polysaccharide-based nanocarriers in vaccine delivery and immune response modulation.
• To explore various types of polysaccharide nanocarriers and their properties.

Main Methods:

• Literature review of polysaccharide nanocarriers for vaccine applications.
• Discussion of different polysaccharide types (chitosan, mannose, glucan, inulin, herb-derived) and their derivatives.
• Analysis of case studies demonstrating enhanced immune responses.

Main Results:

• Polysaccharide nanocarriers offer improved antigen stability, controlled release, and targeted delivery.
• They stimulate both humoral and cellular immunity, exhibiting excellent biocompatibility and biodegradability.
• Specific polysaccharides like chitosan, lentinan, and astragalus show potential as adjuvants and delivery systems.

Conclusions:

• Polysaccharide nanocarriers represent a promising platform for next-generation vaccines, offering enhanced efficacy, stability, and safety.
• Further optimization, mechanistic studies, and clinical validation are crucial for their widespread adoption.
• These innovative systems hold significant potential for vaccine delivery and immunomodulation.
