Research Interests

Our research is focused on two areas. The first emerged from our recent discovery that all human blood contains thousands of autoantibodies which appear to play a role in the clearance of cell and tissue debris generated by the body on a day-to-day basis. We have further shown that this is conserved among all mammals and that ongoing disease leads to an increased production of debris from the organ/tissue affected. This surge of debris enters the blood and subsequently stimulates the immune system to selectively increase the production of autoantibodies that clear this disease-specific debris. We have used human protein microarray technology to detect and identify disease-specific autoantibodies which can now be used as biomarkers to confirm the presence of disease. Thus far, we have thus successfully employed disease-specific autoantibodies as biomarkers to diagnose Alzheimer’s disease, Parkinson’s disease, multiple sclerosis and early-stage breast cancer in human subjects using a single drop of blood. Diagnostic accuracies for each of these diseases exceeds 95% using our analytical strategy. This work was seed-funded by the Foundation Venture Capital Group, and subsequent efforts have led to the establishment of two start-up companies (Durin Technologies, Inc. and Beren Technologies, Inc). The Alzheimer’s diagnostic work is currently funded by a grant from the Osteopathic Heritage Foundation; the Parkinson’s disease studies by the Michael J Fox Foundation. In the future, our new Biomarker Discovery Center, created within the New Jersey Institute for Successful Aging, will spearhead these efforts as well as our new efforts towards diagnosing the effects of traumatic brain injury, where we believe that our diagnostic strategy will be able to detect the presence of neurodegenerative changes in the brain resulting from repeated trauma. We are presently seeking industrial partners to accelerate work on the development of diagnostic test kits for a number of diseases that would lead to eventual FDA approval. A number of patents have been filed with UMDNJ. Our second research focus is to elucidate cellular and molecular mechanisms of Alzheimer’s disease. Most recently, this work has led us to conclude that breakdown of the blood-brain barrier is a requisite early trigger for a number of neurodegenerative diseases, including Alzheimer’s disease, Parkinson’s disease and multiple sclerosis. In view of this, we are now investigating factors and conditions that lead to blood-brain barrier breakdown and are utilizing in vitro model systems to screen for drugs that can block this from happening in blood vessels throughout the brain. This work has already led to a patent for the use of darapladib, an inhibitor of atherosclerosis, for the treatment of all neurodegenerative diseases in collaboration with GlaxoSmithKline. This drug is currently in clinical trial for treatment of atherosclerosis. Other drugs are currently being tested for their ability to block blood-brain barrier breakdown.
