abstract = {Therapeutic vaccines represent a promising treatment option
for (pre)cancerous lesions, such as human
papillomavirus-induced malignancies. They act via
administration of tumor-specific antigens, leading to
induction of antigen-specific cytotoxic T cell responses.
However, vaccination efficiency is often limited when the
antigen is administered alone, due to antigen instability
and inefficient uptake by antigen-presenting cells (APCs).
To address these limitations, nanoparticle-based vaccine
delivery systems are currently under investigation. Here, we
present a novel silica nanoparticle (SiNP)-based vaccine
delivery platform that can be applied for the treatment of
various diseases and cancer types. We show that
surface-functionalized SiNPs are non-cytotoxic and quickly
taken up by APCs. Incorporation of a linker/solubilizer
sequence N-terminal of the epitope allows attachment of
peptides regardless of their solubility as well as efficient
processing and surface presentation by APCs. Whole-body
distribution studies confirmed retention of the antigen at
the injection site and decelerated excretion when connected
to SiNPs. Furthermore, treatment with SiNPs, especially when
combined with the adjuvant poly(I:C), resulted in activation
of dendritic cells capable of priming CD8+ T cells. In
C57BL/6 and MHC-humanized A2.DR1 mice, the SiNP-based
vaccinations induced epitope-specific CD8+ T cells.
Moreover, they exhibited anti-tumor activity and provided a
survival benefit in a tumor model using HPV16
E6/E7-expressing PAP-A2 cells. Thus, the novel SiNP platform
represents a promising new vehicle for therapeutic vaccine
delivery.},
