Understanding how military sexual trauma and PTSD affect brain and immune system health
Official title: Peripheral and central nervous system inflammation associated with military sexual trauma and PTSD
Funded at VA San Diego Healthcare System · NIH-11249541 · Data updated 2026-11-12
This project studies how inflammation in the body and brain relates to PTSD in veterans who experienced military sexual trauma, with a focus on immune signals and nervous system changes over time.

Who could benefit from this research
✓Could help
Veterans (primarily women) with a history of military sexual trauma and PTSD who can commit to long-term follow-up.
✕Less likely to help
Individual participants may not experience direct therapeutic benefits from the study itself, as it is observational.
What this research studies
If you are a veteran who has experienced military sexual trauma, this study will follow participants over several years to look at inflammatory markers and brain-immune communication in relation to PTSD symptoms. Researchers will collect blood samples and clinical information to track how immune signals evolve with mood and anxiety symptoms. The goal is to identify biomarkers that could guide future treatments and personalized care for MST-related PTSD. The study emphasizes longitudinal data to understand how inflammation and CNS signaling develop together with PTSD over time. Participation would involve follow-up visits and sample collection with minimal disruption to daily life.
Why it matters
Potential benefit: Discover biomarkers that could personalize treatment and improve outcomes for MST-related PTSD and associated autoimmune conditions.
How similar studies have gone: Previous research has linked PTSD with increased inflammation, and longitudinal approaches have yielded valuable insights in similar populations.
