Abstract
Methods and compositions for treating cancers (e.g., neural cancers) by dendritic cell vaccination are provided herein.
Claims10
A composition comprising dendritic cells, wherein the dendritic cells present on human leukocyte antigen (HLA) on their surface peptide epitopes, wherein the peptide epitopes are each 9 to 13 amino acids length and comprise the following six amino acid sequences:
- (SEQ ID NO:
- 3)
- RSDSGQQARY from AIM-2;
- (SEQ ID NO:
- 4)
- EADPTGHSY from MAGE-1;
- (SEQ ID NO:
- 5)
- SVYDFFVWL from TRP-2;
- (SEQ ID NO:
- 67)
- IMDQVPFSV, a superagonist peptide from gp100;
- (SEQ ID NO:
- 37)
- VMAGVGSPYV from HER-2;
- and
- (SEQ ID NO:
- 8)
- WLPFGFILI from IL-13 receptor α2,
- wherein the dendritic cells acquired the peptide epitopes in vitro by exposure to synthetic peptides comprising the peptide epitopes.

A process comprising:
- obtaining bone marrow derived mononuclear cells from a patient,
- culturing the mononuclear cells in vitro under conditions in which mononuclear cells become adherent to a culture vessel,
- selecting a subset of the mononuclear cells comprising adherent cells,
- culturing the adherent cells in the presence of one or more cytokines under conditions in which the cells differentiate into antigen presenting cells,
- culturing the antigen presenting cells in the presence of synthetic peptides of the following six antigens:
- TRP-2, MAGE-1, HER-2, IL-13 receptor α2, gp100, and AIM2, wherein the synthetic peptides are each 9 to 13 amino acids in length and comprise the following six amino acid sequences:
- (SEQ ID NO:
- 3)
- RSDSGQQARY from AIM-2;
- (SEQ ID NO:
- 4)
- EADPTGHSY from MAGE-1;
- (SEQ ID NO:
- 5)
- SVYDFFVWL from TRP-2;
- (SEQ ID NO:
- 67)
- ITDQVPFSV, a superagonist peptide from gp100;
- (SEQ ID NO:
- 37)
- KIFGSLAFL from HER-2;
- and
- (SEQ ID NO:
- 8)
- WLPFGFILI from IL-13 receptor α2,
- under conditions in which the antigen presenting cells present the peptides on human leukocyte antigen (HLA), wherein the antigen presenting cells are dendritic cells.
