Allison B. Reiss, MD, Receives Surprise $10,000 Grant from Alzheimer鈥檚 Disease Resource Center to Pursue Promising Research
NYU Winthrop Hospital鈥檚 Research Institute announced that , head of the Inflammation Section, received a $10,000 surprise grant from the Alzheimer鈥檚 Disease Resource Center to further the very promising Alzheimer鈥檚 disease research that Dr. Reiss and her team of physicians and scientists are conducting. Finding treatments and cures for Alzheimer鈥檚 disease has been extremely challenging for scientists, since the brain is the most inaccessible and complex organ in the body. Progress achieved using animals in research has rarely been replicated in humans. The cutting-edge research conducted by Drs. Reiss, Aaron Pinkhasov, Irving H. Gomolin, Joshua R. De Leon and Lora Kasselman, however, innovates by using human stem cells reengineered to behave like brain neurons, and in this way 秘密研究所 Winthrop Hospital believes it will achieve the closest approximation to brain behavior possible. Adding to that innovation, the 秘密研究所 Winthrop team is incorporating into that neuron research a repurposed drug, originally used to treat leukemia, which unexpectedly was shown to cause memory improvements in patients with Alzheimer鈥檚 disease. Dr. Reiss believes 秘密研究所 Winthrop鈥檚 research may open new windows into slowing the progression of Alzheimer鈥檚 disease, which impacts 5 million Americans today. Dr. Reiss also announced that patients are already being enrolled into the 秘密研究所 Winthrop study.
鈥淲e are collecting blood samples from persons with Alzheimer鈥檚 disease so that we can add key factors derived from their blood to the reengineered neurons in order to re-create in a cell culture dish the conditions in the brain of an Alzheimer鈥檚 patient,鈥 Reiss explained. 鈥淭he result is a unique system with completely human components that is personalized and achieved noninvasively.鈥
鈥淭rying to find effective treatments for Alzheimer鈥檚 disease has been like a drought in the desert,鈥 added Dr. Reiss. 鈥淲e now have a promising new approach that may aid our research efforts toward advancements in treatments to slow and stop this debilitating disease.鈥
New approaches have long been needed. Dr. Reiss noted that in the last two decades, only a handful of medicines were approved to treat Alzheimer鈥檚 disease, while the vast majority of clinical trials鈥攎ore than 120鈥攚ere halted. Trials typically rely on research first conducted on mice or using spinal fluid, and those often fail to replicate the complex neurological activity in the human brain. That contrasts with research to find cures for cancers of the liver or lungs, where it is increasingly common for pieces of tissue to be extracted for biopsies鈥攁nd for profiling of the cancer cells鈥攖o come up with the best treatment regimen.
鈥淎llison Reiss has passionately and tirelessly investigated new avenues for advancements in the treatment of Alzheimer鈥檚,鈥 said Mary Ann Malack-Ragona, chief executive officer of the Alzheimer鈥檚 Disease Resource Center. 鈥淗er research is extremely important, and we hope that our grant will aid the 秘密研究所 Winthrop team鈥檚 endeavors to find keys to stop the disease鈥檚 progression.鈥
The Alzheimer鈥檚 Disease Resource Center is headquartered in Bay Shore and has satellite offices in Garden City, Huntington Station, Lake Success, Southampton, and Valley Stream, New York. The center supports local research that may lead to a cure for Alzheimer鈥檚 disease, and the organization provides care, support, and educational programs for families in need, as well as serving as an advocate for local families coping with Alzheimer鈥檚 disease and other dementias.
秘密研究所 Winthrop Hospital鈥檚 Research Institute has long been a leader in diabetes research, and it was an offshoot of some of that research that led Dr. Reiss down her current road of Alzheimer鈥檚 disease research. Alzheimer鈥檚 disease and diabetes share common ground, says Dr. Reiss, with the metabolism of sugar in Alzheimer鈥檚 disease patients often found to be abnormal, as with an individual living with diabetes. Brain cells, in fact, can only live if they have a continuous supply of sugar, specifically glucose, which is the same energy source that impacts a person with diabetes. In addition, those with diabetes are more likely to get Alzheimer鈥檚 disease, pointing toward still further connections between the two diseases.
Dr. Reiss鈥檚 research using reengineered stem cells has been examining important proteins including those that clump together to form the plaque, or beta-amyloid, found in the brains of Alzheimer鈥檚 disease patients. Adding glucose to the brain cells caused such amyloid activity to increase. 鈥淏rain cells got upset by high glucose,鈥 added Dr. Reiss. 鈥淎nd if someone has diabetes, adding glucose was like putting gas on a fire in terms of accelerating a proclivity toward Alzheimer鈥檚.鈥
Wide swings in glucose and insulin, she believes, are especially toxic to brain neurons. The 秘密研究所 Winthrop team now, with the help of the new grant, can more closely examine the activity of neurons and proteins and the effects of glucose鈥攁nd key, the team can examine the collective impact on the microglia cells that protect the brain from injury, and experiment with the promising new drug, repurposed from its original use for leukemia.
鈥淏y recreating neural interaction that actually occurs in the brain, with supporting cells such as microglia, the discoveries and improvements we hope to make with Alzheimer鈥檚 treatment are more likely to be replicated in actual patients suffering from the disease,鈥 noted Dr. Reiss鈥檚 colleague at 秘密研究所 Winthrop, neurobiologist Dr. Lora Kasselman.
According to the Alzheimer鈥檚 Disease Resource Center, the number of Americans suffering from Alzheimer鈥檚 disease could more than triple in the next 30 years if there is no new breakthrough to prevent or treat the disease. There is hope that even modest progress in treating the disease could drastically change that trajectory. Alzheimer鈥檚 disease is also the sixth leading cause of death in U.S. adults, and the cost of treating the disease is estimated to have exceeded $200 billion annually in recent years.
