“…In contrast to other vaccines having to rely on mucosal delivery to access the natural inductive pathway (29,35,39), B 4 T can induce high mucosal immune responses by parenteral administration. Several different, nonexclusive mechanisms have been proposed to explain the production of secretory antibodies after parenteral administration of the antigen, including direct diffusion of soluble or phagocytosed antigens to mucosa-associated lymphoid tissue or activation of antigen-presenting cells at draining lymph nodes, which then migrate to mucosa-associated lymphoid tissue (12). In any event, parenterally administered antigens capable of inducing strong mucosal immunity, such as our B 4 T dendrimer or a few other immunogens so far described (28,37,56), appear to be good candidates for future mucosal vaccines.…”

“…This suggests that while parasite-specific serum IgG may have a role in natural resistance and parenterally induced protective immunity (14,39), such responses are not absolutely required for the expression of protection in the oral vaccine model. The mechanism of protection in this model has not been characterized yet, although stimulation of secretory IgA responses that neutralize the activity of parasite proteins seems likely (10,34) and locally secreted IgG (11) may also play a role. Oral immunization may also have primed cellular responses, leading to accelerated mucosal mastocytosis upon challenge infection; such responses are known to occur after secondary challenge in hamsters (5,30).…”

“…Small controlled doses of Ag can be precisely delivered by needle injection into the skin or muscle. Mucosally delivered vaccines, despite their being easy to administer, however, require much higher doses of Ag to effectively stimulate adaptive immunity and cannot be accurately controlled (12,35). Unfortunately, orally delivered vaccines do not induce good adaptive immune responses unless toxic adjuvants such as cholera toxin are coadministered (36,37).…”
