Systems and methods to genetically modify B cells to express selected antibodies are described. The systems and methods can be used to: obviate the need for classical vaccinations; provide protection against infectious agents for which no vaccinations are currently available; provide protection against infectious agents when patients are otherwise immune-suppressed; and/or provide a benefit provided by a therapeutic antibody, such as in the treatment of autoimmune disorders.

The present invention relates to an immunoprophylactic and therapeutic vaccine comprising peripheral blood mononuclear cells loaded with a natural killer T cell ligand and an antigen, and specifically, to an immunotherapeutic vaccine comprising peripheral blood mononuclear cells loaded with alpha-galactosylceramide, a natural killer T cell ligand and a type of glycolipid. A composition of the present invention is easy to obtain because there is no need to separate specific cells from peripheral blood mononuclear cells. In addition, immunization of peripheral blood mononuclear cells loaded with a natural killer T cell ligand and an antigen not only induces significant levels of activation of natural killer cells and natural killer T cells and cytotoxic T lymphocyte responses, but also has a synergistic effect in the treatment of malignant tumors and thus can be helpfully used as an anticancer immunotherapeutic agent.
