This paper proposes that ME/CFS and similar conditions may develop when the immune system mistakenly attacks certain chemical messengers in the body called vasoactive neuropeptides (VNs). These VNs normally help control heart rate, breathing, temperature, memory, and mood. The authors suggest that after infections or other triggers, people's bodies may lose the ability to recognize these messengers as 'self,' leading to immune attacks that could cause the widespread symptoms seen in ME/CFS.
This paper addresses a fundamental question about ME/CFS pathogenesis by proposing a specific immunological mechanism (autoimmunity against vasoactive neuropeptides) that could explain the constellation of neurological, autonomic, immune, and cognitive symptoms patients experience. If validated, this mechanism could guide development of diagnostic biomarkers and targeted treatments for ME/CFS.
This hypothesis paper presents no experimental data, patient cohorts, or direct evidence of anti-VN autoimmunity in ME/CFS patients—it is a theoretical framework only. It does not establish causation, demonstrate that VN autoimmunity actually occurs in affected individuals, or prove that VN dysregulation is the primary driver rather than a secondary consequence of other pathological processes. Subsequent empirical studies would be needed to test these postulates.
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 →
