Previously, we constructed a chimeric influenza virus that expresses the
highly conserved amino acid sequence ELDKWA of gp41 of human
immunodeficiency virus type 1 (HIV-1). Antisera elicited in mice by
infection with this chimeric virus showed neutralizing activity against
distantly related HIV-1 isolates (T. Muster, R. Guinea, A. Trkola, M.
Purtscher, A. Klima, F. Steindl, P. Palese, and H. Katinger, J. Virol.
68:4031-4034, 1994). In the present study, we demonstrated that intranasal
immunizations with this chimeric virus are also able to induce a humoral
immune response at the mucosal level. The immunized mice had
ELDKWA-specific immunoglobulins A in respiratory, intestinal, and vaginal
secretions. Sustained levels of these secretory immunoglobulins A were
detectable for more than 1 year after immunization. The results show that
influenza virus can be used to efficiently induce secretory antibodies
against antigens from foreign pathogens. Since long-lasting mucosal
immunity in the genital and intestinal tracts might be essential for
protective immunity against HIV-1, influenza virus appears to be a
promising vector for HIV-1- derived immunogens.
