title: Immunoenhancement with flagellin as an adjuvant to whole-killed rabies vaccine in mice.
abstract: Vaccination is the most effective method for preventing rabies virus (RABV) infection in both humans and animals; however, no satisfactory vaccine has been developed for use worldwide. In the present study, we investigated the immunoadjuvant properties of Salmonella Typhimurium flagellin (FljB, FliC, and FljB'-FliC) to improve immune responses against the rabies vaccine (RV) and the protective efficacy of the whole-killed rabies vaccine (WKRV) with or without flagellins in BALB/c mice. We also compared the differences among the three flagellins in terms of immunoadjuvant properties to RV. FljB can cause the WKRV to induce stronger humoral and cellular immune responses than WKRV alone or WKRV with FliC or FljB'-FliC can. Mice immunized with WKRV and FljB produced higher levels of virus-neutralizing antibody (VNA) against RABV than those in the other groups did. Although mice in all treatment groups survived RABV challenge, the body weight loss in the group immunized with WKRV and FljB was lower than in the other groups. These results indicate that FljB is a promising adjuvant for use in the development of effective rabies vaccines.
