Aethlon Medical (OTCBB: AEMD) Announces Multi-Target Exosome Assay Validation
SAN DIEGO - April 12, 2011 (Investorideas.com newswire) Aethlon Medical, Inc. (OTCBB: AEMD) announced today that its wholly owned subsidiary Exosome Sciences, Inc. (ESI) has validated the ability of its Enzyme Linked Lectin Specific Assay (ELLSA) to identify the presence of exosomes underlying the human immunodeficiency virus (HIV), tuberculosis (TB), and various forms of cancer, including ovarian, melanoma, breast, lymphoma, and colorectal. In July 2010, ESI disclosed that it filed a patent relating to the development of an assay that would allow researchers to detect exosomes in blood and other fluids. In addition to research opportunities, Aethlon Medical plans to test ELLSA as a diagnostic to quantify the therapeutic capabilities of the Aethlon Hemopurifier® to remove immunosuppressive exosomes from the circulatory system of those afflicted with cancer. ESI is now preparing a market survey that will be provided to researchers to determine market demand and pricing for ELLSA as a research tool.

Aethlon Medical (OTCBB: AEMD)
At Aethlon Medical, we create revolutionary devices to address infectious disease and cancer. Our devices are designed to be novel platform solutions that fill therapeutic voids or aid in disease diagnosis and monitoring.
Our Hemopurifier® is the first medical device to selectively target the removal of infectious viruses and immunosuppressive proteins from the entire circulatory system. We recently discovered that our Hemopurifier® captures tumor-secreted exosomes that suppress the immune system of those afflicted with cancer. Prior to this discovery, a therapeutic strategy to directly inhibit or reverse the immunosuppressive destruction caused by exosomes did not exist in cancer care. By eliminating this mechanism, we believe our Hemopurifier® can fill an unmet clinical need and provide the benefit of an immune-based therapy without adding drug toxicity or interaction risks to established and emerging treatment strategies.
