A scientific finding by a team of researchers, led by Dr. Aaron Phillips, PhD, an associate professor at the , in collaboration with researchers at King鈥檚 College London offers hope for new treatments for individuals with circulation disorders in the brain and spinal cord.聽
The research team identified the molecular mechanism behind a key process involved in controlling the circulation in the central nervous system, which can play a role in neurological diseases such as Alzheimer鈥檚 and spinal cord injury, as well as some cardiovascular diseases such as hypertension and atrial fibrillation.聽
鈥淚t鈥檚 an exciting finding. Conditions caused by lack of blood flow to the brain and spinal cord are difficult to assess and challenging to treat,鈥 says Phillips, senior author on . 鈥淚t opens the door to potential therapies.鈥澛
The Phillips Lab and at the Cumming School of Medicine spent years developing a computational tool to study how the body regulates circulation to meet the metabolic needs of the nervous system through a process called neurovascular coupling. In addition to developing automated software for the analysis, the tool required new protocols and assessment hardware.聽
The platform made it possible for the team to look at how a specific molecule in neurons, neuronal nitric oxide synthase (nNOS), signals circulation to keep up with the metabolism needs of the central nervous system. For this, they collaborated with the group at King鈥檚 College London who are experts in the field of nNOS regulation. The study published in is the first time an experiment of its kind had been performed in humans.聽
鈥淭his was really important as nNOS is uniquely positioned to play a key role in regulating circulation and ensuring the brain is not starved of blood,鈥 says Dr. Kevin O鈥橤allagher, MD, PhD, at King鈥檚 College London and first author on the study. 鈥淯nderstanding the mechanism is key to both diagnosing and treating individuals with conditions associated with impaired circulation in the central nervous system.鈥
Phillips has launched a new startup, HEMOtx, to help bring these tools to the community.聽
鈥淲e believe that our neurovascular assessment platform and the new knowledge related to nNOS helps in both diagnosing circulation disorders in the central nervous system and in developing new therapeutics for these conditions,鈥 says Phillips.
Dr. Robert Rose, PhD, Libin Cardiovascular Institute deputy director, says navigating the complexities of the human system is key in predicting and preventing disease and in providing personalized care.聽
鈥淒r. Phillips and the team have made an important discovery with the potential to impact patients. We are proud of the work they are doing and congratulate them on this impressive study."
