This paper proposes that ME/CFS and similar fatigue disorders may be caused by the immune system attacking special messenger molecules in the body called vasoactive neuropeptides. These molecules normally help control energy metabolism, nerve function, and immune responses. The authors suggest that when antibodies damage these molecules, it could explain the severe fatigue and other symptoms seen in ME/CFS.
This hypothesis identifies vasoactive neuropeptides and their interactions with heat shock proteins as potential therapeutic targets for ME/CFS research. If validated, it could explain both the neurological and metabolic dysfunction observed in ME/CFS and suggest new diagnostic biomarkers and treatment strategies.
This is a hypothesis paper, not an empirical study—it presents theoretical arguments without experimental data, patient samples, or clinical evidence. It does not establish that VN autoimmunity actually occurs in ME/CFS patients or that HSP-VN complexes cause fatigue symptoms. The proposal remains speculative and requires rigorous testing in clinical and laboratory studies.
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 →
