Researchers at the National Institute on Aging (NIA) have developed a straightforward method to elicit immune responses to specific cancers and AIDS by using a chemoattractant-based antigen delivery strategy. The strategy uses formulations composed of chemokines fused to toxic moieties (aka “chemotoxins”) to preferentially and specifically eliminate chemokine receptor-expressing cells. The method uses the natural ability of the chemokines to stimulate measurable and improved humoral and immune responses.
- Chemokines can be of viral or microbial (B-Defensin) origin.
- This method can also be used to cause inflammation to specifically target immune cells to increase immunogenicity for malignant tumors using SPANX-B and Laminin tumor antigens.
Potential Commercial Applications
- A potential immunotherapeutic antigen for the treatment of several malignancies including lymphoma, breast, lung, and ovarian.
- Use as a monoclonal antibody.
- Antigens, such as SPANX-B and Laminin, can also be used as prognostic and diagnostic agents for the monitoring of disease.
- In contrast to recombinant proteins, these small peptides can be more easily manufactured.
- They help to facilitate the activation of cells in a more specific and therapeutically effective way.
- Active immune system will do a better job attacking cancer cells.
- Simple and less invasive.
Collaborative Research Opportunity
The National Institute on Aging (NIA) is seeking parties interested in collaborative research to further evaluate or commercialize effective vaccines that target bacterial, viral, or tumor antigens. Any or all of the inventions in this announcement are available for co-development and collaboration.
