Research axis:

  • Neurovascular unit dysfunctions at longterm after juvenile traumatic brain injury

Scientific expertise:

  • In vivo models of traumatic brain injury
  • Immunohistochemistry and image analysis
  • RNAi in vivo
  • Astrocyte and organotypic cultures

Projects:
The neurovascular unit (NVU) is composed of cerebral blood vessels, neurons, and scattered in between them, an astrocyte sheath. The homeostasis of this unit is critical for normal brain function and activity, especially the maintenance of blood-brain barrier (BBB) properties that regulate entry of blood components and clearance of brain waste. The astrocyte network contributes to water and ion homeostasis, as well as brain energy metabolism.
Our research is focused on the changing physiological properties of the NVU after traumatic brain injury (TBI). TBI can occur at any point in a person’s lifetime, affects a large number of soldiers in the battlefield, and is known to result in both short- and long-term consequences. The functional and molecular consequences after TBI might be a result of the changing NVU properties observed near the TBI injury site, and at a distance from the site of the impact. We are currently investigating the molecular mechanisms behind TBI-induced dysfunctions in NVU homeostasis using a rodent model. We evaluate these changes using magnetic resonance imaging (MRI), behavioral testing paradigms, and histological and molecular biology techniques to address specific protein targets at the NVU interface (for example: aquaporins…). We hope our understanding of these basic mechanisms will help to generate new target-specific drugs to promote functional recovery of individuals affected by brain injury.
