Targeting immune-cell energy to reduce brain damage after traumatic brain injury
Bioenergetic regulation of the innate immune response after TBI
This project will try blocking a sugar-processing enzyme in brain immune cells to lower inflammation and protect the brain after a traumatic brain injury.

What this research studies
From a patient perspective, researchers are focusing on microglia, the brain's immune cells, which can damage neurons after a head injury by producing inflammatory molecules and reactive oxygen. They will use mice engineered to lack the enzyme hexokinase-2 in microglia and give an Hk2-blocking drug after controlled brain injury to see whether inflammation, neuron and blood vessel damage, and long-term behavior improve. Lab-grown microglia will also be used to measure changes in sugar use, gene activity, and harmful oxidant production when Hk2 is blocked. The work aims to determine whether reducing microglial glycolysis preserves axons and dendrites that are important for recovery after TBI.
Who could benefit from this research
Good fit: People who recently experienced a traumatic brain injury and are showing signs of inflammation or worsening neurologic function would be the likely candidates for future related trials.
Not a fit: Patients with non-traumatic brain disorders or those with long-standing, stable injuries are unlikely to get direct benefit from this early preclinical work.
Why it matters
Potential benefit: If successful, this approach could lead to new treatments that reduce inflammation and help preserve nerve connections after traumatic brain injury.
How similar studies have performed: Prior laboratory and animal studies, including work from this team, have shown that limiting glycolysis can calm microglial activation, but using Hk2 inhibitors in humans remains largely untested.
