Modified POTE Peptides for Cancer Immunotherapy

POTE is a novel tumor antigen expressed in a variety of cancers including breast, prostate, colon, lung, ovary, and pancreas cancers.  POTE has limited expression in normal tissues and therefore a specific target for cancer treatments, including immunotherapy.  The researchers seek statements of capability or interest from parties interested in collaborative research to further develop, evaluate, or commercialize immunogenic peptides. 

Antigen-specific cancer immunotherapy often relies on identification of epitopes expressed by cancer cells that can targeted by cytotoxic T cells (CTL).  However, the CTL repertoire against high-affinity cancer epitopes is often ineffective because cancer epitopes may share a similar structure to natural "self" antigens.  As a result, cancer cells are not recognized by CTLs and destroyed.  The enhanced POTE epitopes induce a stronger immune response than natural responses.  These modified epitopes are more effective at inducing CTL against POTE expressing cancer cells and have greater potential to serve as cancer vaccine targets.
