What this research studies

Researchers are focusing on an early toxic form of the tau protein called cis P-tau that appears after traumatic brain injury or reduced blood flow to the brain. They will study how the enzyme JNK3 makes cis P-tau and how a neuron-protective response driven by REST might oppose this damage. Work will use cell experiments, mouse models of TBI and vascular dementia, and samples or data from patients across mentored (K99) and independent (R00) phases. Later work will test whether blocking JNK3 activity or restoring REST can reduce tau damage and protect brain cells in chronic stages.

Who could benefit from this research

Good fit: People who have had a recent traumatic brain injury or who have vascular-related cognitive impairment or dementia and who are willing to provide clinical data or samples would be the best candidates to participate or contribute.

Not a fit: Patients whose cognitive decline is driven by unrelated mechanisms or who cannot or will not participate in research may not directly benefit from this project.

Why it matters

Potential benefit: If successful, this could lead to treatments that reduce early tau-related damage and slow or prevent cognitive decline after brain injury or vascular dementia.

How similar studies have performed: Prior research has identified cis P-tau as an early toxic tau form in TBI and Alzheimer’s, but targeting JNK3 and boosting REST is a newer therapeutic approach still mainly tested in preclinical models.
