This review examines how problems with energy-producing structures in cells (mitochondria) and immune system dysfunction may contribute to ME/CFS. The authors propose that two key areas—the gut and immune cells—work together with the body's natural sleep-wake cycle to drive the condition. They also explore how factors like viral infections, gut bacteria, and hormones may play interconnected roles in ME/CFS symptoms.
Understanding how different biological systems interact in ME/CFS could lead to better explanations for why patients experience such diverse symptoms and guide development of targeted treatments. This integrated perspective may also help researchers understand other complex conditions like fibromyalgia and depression that share similar features with ME/CFS.
This review does not provide experimental evidence that any proposed mechanism actually causes ME/CFS—it synthesizes existing literature to suggest plausible interactions. It cannot establish which factors are primary drivers versus secondary consequences, and correlation between findings in different studies does not prove causation. Clinical trials would be needed to validate whether targeting these mechanisms actually improves patient outcomes.
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 →
The first block is for the primary paper and is the citation you should use in research work. The atlas-snapshot line only applies if you are specifically referring to this atlas’s reading of the paper on the date shown.
