Influenza viruses remain a critical global health concern. More efficacious
vaccines are needed to protect against influenza virus, yet few adjuvants are
approved for routine use. Specialized proresolving mediators (SPMs) are powerful
endogenous bioactive regulators of inflammation, with great clinical
translational properties. In this study, we investigated the ability of the SPM
17-HDHA to enhance the adaptive immune response using an OVA immunization model
and a preclinical influenza vaccination mouse model. Our findings revealed that
mice immunized with OVA plus 17-HDHA or with H1N1-derived HA protein plus 17-HDHA
increased Ag-specific Ab titers. 17-HDHA increased the number of Ab-secreting
cells in vitro and the number of HA-specific Ab-secreting cells present in the
bone marrow. Importantly, the 17-HDHA-mediated increased Ab production was more
protective against live pH1N1 influenza infection in mice. To our knowledge, this
is the first report on the biological effects of ?-3-derived SPMs on the humoral
immune response. These findings illustrate a previously unknown biological link
between proresolution signals and the adaptive immune system. Furthermore, this
work has important implications for the understanding of B cell biology, as well
as the development of new potential vaccine adjuvants.
