Bioengineering towards self-assembly of particulate vaccines

Area of Science:

• Vaccinology and immunology
• Biomaterials science
• Infectious disease prevention

Background:

• Subunit vaccines offer a safer alternative to whole organism vaccines but often lack sufficient immunogenicity.
• There is a significant need for improved vaccine strategies to combat infectious diseases effectively.
• Antigen carriers are essential for enhancing the immune response elicited by subunit vaccines.

Purpose of the Study:

• To review the use of natural and synthetic self-assembling polymers and proteins as antigen carriers.
• To focus on advances in the in vivo assembly of antigen-displaying polyester inclusions for vaccine development.
• To explore bioengineering approaches for designing tailor-made particulate vaccines that induce protective immunity.

Main Methods:

• Review of literature on self-assembling polymers and proteins for antigen encapsulation and display.
• Analysis of recent advances in in vivo assembly of antigen-displaying polyester inclusions.
• Discussion of bioengineering strategies for particulate vaccine design.

Main Results:

• Self-assembling materials can encapsulate and display antigens, serving as immunogenic carriers.
• In vivo assembly of antigen-displaying polyester inclusions shows promise for vaccine development.
• Particulate vaccines enhance antigen uptake by antigen-presenting cells, promoting adaptive immune responses.

Conclusions:

• Self-assembling polymers and proteins are promising candidates for developing safe and immunogenic subunit vaccines.
• Bioengineered particulate vaccines can be designed to fine-tune immune responses for effective protection against infectious diseases.
• Advances in in vivo assembly offer novel strategies for creating next-generation vaccines.
