Summary
Our previous work indicates that evoked human blood borne factors confer protection against injury, due to loss of blood flow in heart muscle, when a brief stress is remotely applied to a limb (remote ischemic preconditioning). We have identified these proteins that appear to activate genetic and metabolic regulation of adaptive cell survival processes. We will now test their individual and combined capacity, efficiency and mechanisms of protection in the heart using cell and clinical models.

Summary
Heart surgery with the heart placed into arrest causes inflammation and tissue damage due to interrupted circulation. We know that prior brief interruption and restoration of blood supply called remote ischemic preconditioning (IPC) can protect heart and lungs against damage. Our previous studies indicate that IPC involves a circulating factor that protects the tissue by optimizing energy preservation. This knowledge can be applied to organ transplants, protection from stroke and heart attack.
