abstract = {The Gardasil-4® vaccine targets HPV types 6, 11, 16 and 18
and is formulated with amorphous alum. Cervarix® targets
HPV types 16 and 18 using AS04 (Al(OH)3 + TLR4 agonist MPL)
to enhance immune response. Cervarix elicits higher
cross-protection against other high-risk HPV types, likely
mediated by AS04.To investigate mechanisms of
cross-neutralizing potential, six monozygotic twins (12
females aged 9-13 years) were vaccinated with either
Cervarix or Gardasil-4 (2 doses, 6 months apart). Serum
neutralizing antibody titers against HPV
6,16,18,31,33,45,52, and 58 were assessed pre-vaccination
and 7 days post-second dose. Multi-omic single cell RNA and
ATAC sequencing of PBMCs was performed at the latter
timepoint.Cervarix generated higher cross-neutralizing
antibody titers than Gardasil-4. Higher frequencies of
dendritic cells and memory B cells were observed. Gene Set
Enrichment Analysis (GSEA) indicated enhanced pathways
related to NOTCH2 signaling in DCs and cell cycling/RNA
translation in B cells, correlating positively with
cross-neutralizing antibody titers. Increased chromatin
accessability in genes related to NOTCH signaling in cDC1
was also observed. Cervarix-vaccinated subjects showed
increased DC-to-memory B signaling, through upregulation of
NOTCH ligands. Engagement of NOTCH was associated to BCL2
expression in memory B cells, supporting an anti-apoptotic
state.Increased DC signaling, including NOTCH, through AS04
in Cervarix supports cell survival and sustained RNA
translation in memory B cells, 7 days post-vaccination. This
may enhance adaptive immune cell maturation, providing a
mechanism that can lead to improved cross-reactivity.},
