Her2/neu Vaccine Protects Against Tumor Growth

Detailed Technology Description

University of California, Irvine researchers have developed a recombinant polynucleotide encoding Her2/neu target antigen. This recombinant polynucleotide contains two regions of the human Her2/neu molecule which demonstrated the lowest degree of homology with other known normal human proteins as the putative target antigen sequence for a genetic vaccination strategy. This target sequence was chosen to minimize any potential cross reactive auto-immune response and to maximize specificity of the elicited immune response. These portions of human Her2/neu contain some of the previously identified T cell epitopes. Because this sequence is predominantly intracellular and represents a truncated or partial protein sequence, the protein is anticipated to be rapidly degraded and presented in the context of MHC class I and thus be available for CTL recognition.

Title: Her2/neu target antigen and use of same to stimulate an immune response
Usefulness: Her2/neu target antigen and use of same to stimulate an immune response
Summary: The polynucleotide encoding a Her2/neu target antigen is useful for stimulating immunoeffector cells or an immune response in a subject against cancer cells expressing Her2/neu. The encoded Her2/neu target antigen polypeptide is useful as a tag to detect or isolate the fusion protein containing the Her2/neu target an immune response stimulated by the Her2/neu target antigen. The Her2/neu target antigen polynucleotides and polypeptides are useful in genetic or polypeptide vaccination strategies.
Novelty: New Her2/neu target antigens and polynucleotides encoding them, useful for stimulating immunoeffector cells or an immune response in a subject against cancer cells expressing Her2/neu, and for vaccination strategies
