  • OMPs were purified by organic phase partitioning using chloroform-methanol extraction of a total membrane vesicle preparation.

  • a pulse of IgA activity also occurred between Days 10 -0 14 while the IgM response peaked at Day 10 and gradually subsided over the next 40 - 50 days.

Cytotoxicity against EL4 and YAC targets were not detected. Neither SAMA4 vaccinated mice or mice given only ovalbumin produce Ova-specific cytotoxic T cells . It is clear from these results that intradermal delivery of SAMA4 adjuvanted antigens such as ovalbumin is very effective in generating cytotoxic T cell responses in mice.

It is therefore believed that the composition of the present invention may be beneficially used in the treatment or prevention of a number of diseases in man such as skin immune disorders (e.g. melanoma, atopic dermatitis, psoriasis), urogenital tract infection (e.g. Candida, sexually transmitted diseases), upper and lower respiratory tract infection (e.g.

Abstract

Cette invention concerne une composition destinée à être utilisée pour induire chez des mammifères une réponse immunitaire cellulaire et/ou humorale (mucosique et systèmique) contre un antigène. Cette composition est formée de l'antigène piégé dans des liposomes qui sont eux-mêmes incorporés dans un complexe de stimulation immunitaire (ISCOM). Les liposomes sont de préférence formés avec du N-[1-(2,3-Dioléoyloxy)propal]-N,N,N-triméthyl-ammoniumméthylsulfate (DOTAP). Ces compositions peuvent être administrées par diverses voies telles que les voies intradermique, intratrachéale, intranasale, orale, rectale ou encore par irrigation.
