Simard Research Lab
The J Marc Simard, MD, PhD lab investigates molecular mechanisms of cerebral edema formation, blood-brain barrier dysfunction, and neuroinflammation after acute and chronic CNS injury. The lab's efforts led to the discovery of the SUR1-TRPM4 channel, which contributes to secondary injury after stroke, traumatic brain and spinal injury.
The laboratory's efforts led to the discovery of the novel SUR1-TRPM4 channel, which contributes to secondary injury after stroke and traumatic brain and spinal injury.
Multiple clinical trials have directly stemmed from this work, including the ongoing phase III multisite CHARM trial, which investigates the use of the SUR1 inhibitor glyburide to reduce cerebral edema after ischemic stroke.
