WT1-H/K-HELP-survivin-H/K-HELP-MAGE-A4-H / K-HELP-MUC1-22 Peptide-loaded Autologous Dendritic Cells
wt1-h/k-help-survivin-h/k-help-mage-a4-h / k-help-muc1-22 peptide-loaded autologous dendritic cells
"A preparation of autologous dendritic cells (DCs) pulsed with helper/killer-hybrid epitope long peptides (H/K-HELP) of Wilms tumor 1 (WT1 H/K-HELP), survivin, melanoma-associated antigen 4 (MAGE-4) and human mucin 1-22 (Muc1-22), with potential immunomodulating and antineoplastic activities. Upon administration of WT1-H/K-HELP-survivin-H/K-HELP-MAGE-A4-H / K-HELP-Muc1-22 peptide-loaded autologous DCs may stimulate the host immune system to mount an anti-tumoral cytotoxic T lymphocyte (CTL), T-helper (Th), and antibody responses against WT1-, survivin-, MAGE-4- and Muc1-22-expressing cancer cells, resulting in tumor cell lysis. WT1, survivin, MAGE-4 and Muc-1-22, tumor-associated antigens (TAAs), are overexpressed on a variety of cancer cells. The DCs loaded with the long fusion polypeptides, comprising of one or more helper epitopes and killer epitopes, may enhance antigen-specific CTL and Th cell production more efficiently than when the DCs are loaded with a mixture of helper epitope and killer epitope."
