This study explores how the brain, hormones, and immune system are connected in ME/CFS. Researchers propose that immune cells communicate with the brain through special chemical messengers, and that problems in this communication system may contribute to ME/CFS symptoms. The study reviews evidence that people with ME/CFS have abnormal levels of certain immune markers and hormones.
This study emphasizes that ME/CFS involves dysregulation across multiple biological systems—not just fatigue—providing early conceptual support for the neuroimmune dysfunction model that guides modern research. Understanding these connections is important for developing treatments that target the underlying immune and hormonal abnormalities rather than symptoms alone.
This review does not establish causation; it presents correlational immune findings and does not prove that neuroendocrine-immune dysfunction causes ME/CFS or that correcting these abnormalities will resolve disease. The cited immune markers (elevated HLA-DR, IL-2 receptors, CD4/CD8 ratio changes) may be secondary to disease rather than primary drivers, and their clinical significance remains unclear without longitudinal or intervention data.
About the PEM badge: “PEM required” means post-exertional malaise was an explicit required diagnostic criterion for participant inclusion in this study — not that PEM was studied, observed, or discussed. Studies using criteria that do not require PEM (e.g. Fukuda, Oxford) are tagged “PEM not required”. How the atlas works →
