Abstract:
1. A method of raising an immune response, comprising: administering to an animal a composition comprising a carrier, and an isolated targeted antigen, the isolated targeted antigen comprising an antigen bound to a targeting moiety, wherein the targeting moiety is selected from the group consisting of an antibody, an antibody fragment and an antibody binding domain; and wherein the targeting moiety binds to lymphocyte Peyer's Patch adhesion molecule (LPAM) receptor on lymphocytes that home to MAdCAM + mucosal lymphoid tissues; and allowing the isolated targeted antibody to home to MAdCAM+ ± mucosal lymphoid tissue of the animal and raise immune response; wherein the antigen is any of: (a) an antigen isolated from a pathogen selected from the group consisting of Salmonella, Cholera, Helicobacter pylori , HIV, Candida, P. gingivalis, enteropathogenic Escherichia coli , and gut parasites; (b) an antigen isolated from a cellular component, wherein the cellular component is selected from the group consisting of gut associated toxins, gut hormone, and gut hormone receptors; and (c) an antigen isolated from gut associated cancers cell; and wherein the antigen is bound to the targeting moiety by a type of binding selected from the group consisting of affinity conjugation, chemical cross-linking and genetic fusions.
