56 . A method of expanding antigen-specific T cells in vitro comprising:
isolating peripheral blood mononuclear cells (PBMCs) from a cancer patient; incubating the isolated PBMCs with an immunogenic amount of an αCD40-(PL-Ag)x or αCD40-(Ag-PL)x vaccine, wherein Ag is a tumor associated antigen and x is an integer 1 to 20; expanding the PBMCs in the presence of an effective amount of IL-2; harvesting the cells; and assessing the cytokine production by the cells to determine the presence of anti-cancer specific T cells.
57 . A tumor associated antigen-specific T cells made by the method comprising:
isolating peripheral blood mononuclear cells (PBMCs) from a cancer patient; incubating the isolated PBMCs with an immunogenic amount of an αCD40-(PL-Ag)x or αCD40-(Ag-PL)x vaccine, wherein Ag is a tumor associated antigen and x is an integer 1 to 20; expanding the PBMCs in the presence of an effective amount of IL-2; harvesting the cells; and assessing the cytokine production by the cells to determine the presence of tumor associated antigen-specific T cells.
58 . A therapeutic vaccine comprising a fusion protein comprising the formula: Ab-(PL-Ag)x; Ab-(Ag-PL)x; Ab-(PL-Ag-PL)x; Ab-(Ag-PL-Ag)x; Ab-(PL-Ag)x-PL; or Ab-(Ag-PL)x-Ag; wherein Ab is an antibody or fragment thereof; PL is at least one peptide linker comprising at least one glycosylation site; Ag is at least one cancer antigen; and x is an integer from 1 to 20.Join the waitlist — get patent alerts
