A major pathway for B cell acquisition of lymph-borne particulate antigens relies
on antigen capture by subcapsular sinus macrophages of the lymph node. Here we
tested whether this mechanism is also important for humoral immunity to
inactivated influenza virus. By multiple approaches, including multiphoton
intravital imaging, we found that antigen capture by sinus-lining macrophages was
important for limiting the systemic spread of virus but not for the generation of
influenza-specific humoral immunity. Instead, we found that dendritic cells
residing in the lymph node medulla use the lectin receptor SIGN-R1 to capture
lymph-borne influenza virus and promote humoral immunity. Thus, our results have
important implications for the generation of durable humoral immunity to viral
pathogens through vaccination.
