    Biodegradable poly(CTTH-iminocarbonate) polymers effectively deliver antigens. These polymers enhance antibody responses, showing higher titers than other materials in mice.

    Area of Science:

    • Biomaterials Science
    • Immunology
    • Polymer Chemistry

    Background:

    • Biodegradable polymers offer potential for controlled antigen delivery.
    • The adjuvant properties of polymer degradation products are crucial for immune response.
    • Evaluating novel polymer systems for vaccine development is ongoing.

    Purpose of the Study:

    • To investigate the efficacy of poly(CTTH-iminocarbonate) as a biodegradable antigen delivery system.
    • To compare the immune response elicited by poly(CTTH-iminocarbonate) with a control polymer.
    • To assess the adjuvant potential of the primary degradation product, CTTH.

    Main Methods:

    • Synthesis and characterization of poly(CTTH-iminocarbonate) and poly(bisphenol A-iminocarbonate).
    • Subcutaneous implantation of polymeric antigen delivery devices in male CD-1 mice.

  • Measurement of serum antibody titers against bovine serum albumin (BSA) over 56 weeks.

    • Main Results:

    • Poly(CTTH-iminocarbonate) demonstrated effective antigen release and elicited a significant immune response.
    • The primary degradation product, CTTH, exhibited adjuvant properties comparable to established adjuvants.
    • Higher anti-BSA antibody titers were observed in mice treated with poly(CTTH-iminocarbonate) devices compared to poly(bisphenol A-iminocarbonate) devices (P < 0.006).

    Conclusions:

    • Poly(CTTH-iminocarbonate) is a promising biodegradable material for antigen delivery.
    • The polymer's degradation products contribute to its adjuvant efficacy.
    • This system offers a potential advancement in vaccine development strategies.
