Six hours after oral immunization with the Salmonella construct, mice had 12.1- and 8.4-fold increases in expression of IL-12 p40 mRNA in the Peyer's patches and mesenteric lymph nodes, respectively, compared with control mice receiving only saline.

The constitutive expression of IL-12 p35 mRNA at these mucosal sites coupled with a rapid and dramatic induction of IL-12 p40 mRNA following immunization with wild-type or attenuated strains of S. dublin is consistent with other investigations which support a role for IL-12 in modulating cell-mediated immune responses against intracellular pathogens.

However, since these molecules are toxic and cannot be used in human vaccines, it is important to study whether their non-toxic mucosa-binding B subunits, CTB and LTB, can be used as alternative safe mucosal adjuvants and/or carrier molecules.

We have as a model protein antigen used human gammaglobulin (HGG) for admixture with or chemical conjugation to recombinantly produced CTB and LTB, respectively, and measured antigen-specific local secretory IgA antibodies in saponin extracts from intestine and lung tissue by ELISA following intra-nasal (i.n.) or per-oral (p.o.) immunization.
