 AB    We have immunized mice i.m. or intranasally and rabbits i.m. with HIV
       gp160 (MicroGeneSys) formulated with alum or proprietary adjuvants (PA,
       Pharmos) and/or meningococcal outer membrane protein proteosomes. When
       administered i.m., proteosomes plus alum or PA formulations (with or
       without proteosomes) induced improved and broadened immune responses
       against several gp160 epitopes compared to the standard gp160
       alum-adjuvanted vaccine in both mice and rabbits. Moreover, either PA or
       proteosomes dramatically enhanced immunogenicity following intranasal
       immunization and proteosome formulation markedly boosted IgA responses.
       Data analyzed using a combination of ELISA, quantitative Western Blot
       and PEPscan techniques show that altering the presentation, formulation
       and route of administration of gp160 influences both quantitative and
       qualitative aspects of epitope specific IgG and IgA immune responses.
       These data are encouraging for the development of enhanced i.m. or
       intranasal sub-unit formulations of gp160 vaccines for HIV vaccine
       therapy.
