Australian researchers using NanoString transcriptomics have mapped immune gene activity in Gulf War Illness (GWI) veterans, revealing changes in blood-linked immune genes.

Lead author Dr. Natalie Eaton-Fitch stresses the need for large-scale validation to confirm biomarkers and explore therapeutic options.

Professor Sonya Marshall-Gradisnik says the work fills a gap in Australian cohorts and showcases the value of multidisciplinary, innovative technologies in understanding GWI.

The study frames GWI as a condition affecting up to about one-third of Gulf War veterans, with symptoms like chronic fatigue, pain, brain fog, and sleep disturbances.

Researchers highlight the lack of an existing diagnostic test or approved treatment for GWI and point to biomarker identification and targeted therapies as a path forward.

The absence of a current diagnostic or approved treatment for GWI underscores the potential impact of identifying biomarkers to guide future research and therapy development.

The Griffith University NCNED-led study identifies 33 significant gene changes indicative of chronic inflammation and immune activation years after Gulf War exposures.

The findings are published in PLOS ONE in a paper titled Immune transcriptomic changes in Australian Gulf War veterans, adding new evidence and potential biomarkers for GWI.
