Patent ID: 7195758

Claim:
A method for inducing a T cell mediated immune response in the immune system of an individual which comprises: (a) withdrawing B cells from said individual, (b) culturing said B cell under conditions comprising a lymphocyte proliferating agent, wherein the lymphocyte proliferating agent is IL-4 that result in proliferation and activation of the B cells and an immunosuppressive agent, wherein the immunosuppressive agent is cyclosporin A, (c) isolating activated B cells from the culture of step (b) and using said activated B cells as antigen presenting cells, APCs, (d) presenting a desired tumor associated antigen to said APCs of step (c), (e) administering an effective amount of said APCs of step (d) to said patient to modulate an immune response, (f) at fixed intervals thereafter preparing additional APCs from the culture of step (b), and (g) presenting desired antigen to said additional APCs and administering an effective amount of said additional APCs to said patient, wherein the modulation of the immune system is the generation of a T-cell mediated immune response.
