Using the body's cholinergic anti-inflammatory pathway to reduce brain inflammation and mood and thinking problems after traumatic brain injury
Harnessing the Cholinergic Inflammatory Reflex to Alter Neuroinflammation and Neuropsychiatric Consequences Following Traumatic Brain Injury
This project tests whether stimulating the vagus nerve or giving a drug called anatabine can lower brain inflammation and improve mood, memory, and behavior after blast-related traumatic brain injury.

What this research studies
The team uses a rodent model of blast-related traumatic brain injury to study whether activating the cholinergic inflammatory reflex can change brain inflammation and related behavioral problems. They will apply vagus nerve stimulation (a neuromodulation method) and give anatabine (a cholinergic agonist) after injury, then measure inflammatory markers, circuit changes in areas like the hippocampus and amygdala, and behavior. Findings will help decide whether these approaches could move toward human testing and potentially guide new treatments for people with TBI.
Who could benefit from this research
Good fit: People with a history of blast-related or other moderate-to-severe traumatic brain injury who have ongoing neuropsychiatric symptoms would be the likely candidates for follow-on human trials.
Not a fit: People with only very mild or fully recovered concussions, or whose symptoms are caused primarily by unrelated psychiatric or neurodegenerative conditions, may not benefit from these specific anti-inflammatory approaches.
Why it matters
Potential benefit: If successful, these approaches could lead to treatments that reduce neuroinflammation and improve mood, memory, and behavior after blast-related TBI.
How similar studies have performed: Vagus nerve stimulation has shown anti-inflammatory effects and clinical benefits in some neurological and psychiatric conditions, while use of anatabine for TBI is more experimental and less tested.
