title: Red blood cells as delivery system for recombinant HSV-1 glycoprotein B: immunogenicity and protection in mice.
abstract: The immunotherapeutic potential of autologous red blood cells (RBC) coupled to the secretory form of herpes simplex virus type 1 (HSV-1) glycoprotein B (gB1s) was examined with a mouse model of HSV-1 infection. C57BL/6 mice were immunized intraperitoneally with gB1s (0.05 microgram per dose) linked to RBC, or mixed with Freund's complete or bound to AlPO4 adjuvants (0.5 microgram per dose). Mice immunized with RBC coupled gB1s were protected against lethal and latent HSV-1 infection, and developed an anti-HSV antibody response, as measured by ELISA and HSV-1 neutralization assays, similar or higher than that elicited by the same antigen in Freund's complete adjuvant, which suggested that autologous RBC coupled to gB1s may provide an effective and safe method of immunization against HSV infection.
