AB 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.
