Aethlon Medical Announces Cancer Treatment Discovery

SAN DIEGO--(HSMN NewsFeed)--Aethlon Medical, Inc., (OTCBB:AEMD ) announced today that researchers have discovered the Aethlon Hemopurifier® is effective in capturing particles that suppress the immune response in cancer patients. The particles, known as exosomes, are released by solid tumors, lymphomas, and leukemia. exosomes induce T-cell apoptosis (programmed cell death), and block T-cell signaling, proliferation, and cytokine production. High concentrations of circulating exosomes correlate with reduced T-cell production and tumor progression in cancer patients.

In studies led by Dr. Douglas Taylor at the University of Louisville, 60% of circulating exosomes were removed from the blood of ovarian cancer patients during first pass (approximately 10-minutes) through a small scale Hemopurifier®. The capture data was consistent over the course of five different studies. The ability to reduce circulating exosomes would likely reverse immune suppression and increase patient responsiveness to both immunotherapy and chemotherapy. Dr. Taylor is a recognized authority on the causative effects of immune suppression in cancer patients. He is the credited with the initial characterization of exosomes and is the leading peer reviewed author on the subject.

Based on initial study observations, the Aethlon Hemopurifer® is positioned to address the unmet medical need of inhibiting exosome production in cancer patients. As a result, Aethlon will increase the focus of its treatment opportunities to include both the infectious disease and cancer markets. Related to this news, a detailed audio presentation by Dr. Taylor and Aethlon Chairman and CEO, James A. Joyce can be accessed online at:
