Neutralizing the neurodegenerative effect of ALS-related HERV-K using antibodies

This technology relates to the therapeutic use of antibodies to decrease the potential neurodegenerative effect of the HERV-K retrovirus. Previous work has shown that patients with Amyotrophic Lateral Sclerosis (ALS) can have HERV-K activation. In animal models, activation of HERV-K can lead to neurodegenerative symptoms similar to those exhibited by ALS patients. This neurodegenerative effect is thought to be caused by the release of HERV-K envelope proteins into the extracellular space. Work with monoclonal antibodies in vitro has neutralized the toxicity of this protein.
