Single Chain Antibody (Mab69) against the NG2 proteoglycan

AAV based viral vectors that express either AAV-NG2Ab or AAV-NT3 have been shown to provide improved recovery of motor function in models. Background: Spinal Cord Injury (SCI) affects nearly 270,000 Americans and is a common cause of permanent disability and death in children and adults. Despite being a significant burden to the patients, society and healthcare industry, SCI currently has no treatment. It is known that, upon SCI, macrophages/ microglial cells rush to the site and contribute in development of inflammatory response at the injury epicenter. Therefore manipulating these first responders to deliver desirable proteins such as


neutralizing antibodies to inhibitory proteins, or


to the site of injury represents an excellent therapeutic strategy. Technology Overview: Researchers at Stony Brook University have developed AAV based viral vectors that express either NG2-neutralizing antibody (AAV-NG2Ab) or Neurotrophins (AAV-NT3) and have been shown to provide improved recovery of motor function in relevant animal models. The vectors have high tropism for both neuronal and glial cells and carries a promising potential as gene therapy vector for SCI and other neurodegenerative injuries.
