The Deleterious Effects of Oxidative and Nitrosative Stress on Palmitoylation, Membrane Lipid Rafts and Lipid-Based Cellular Signalling: New Drug Targets in Neuroimmune Disorders.
Morris, Gerwyn, Walder, Ken, Puri, Basant K et al. · Molecular neurobiology · 2016 · DOI
Quick Summary
This review explains how harmful molecules called oxidative and nitrosative stress damage specific fatty structures in cells that are important for cell communication and brain function. These damaged structures may contribute to ME/CFS, along with other conditions affecting the brain and immune system. The authors suggest that omega-3 fatty acid supplements might help restore these damaged cellular structures.
Why It Matters
This study identifies a potentially unifying cellular mechanism—disrupted lipid-based signaling—that could explain multiple neurological and immunological symptoms in ME/CFS. Understanding this pathway could lead to targeted therapeutic approaches like omega-3 supplementation that address root causes rather than just symptoms.
Observed Findings
- Oxidative and nitrosative stress inhibits S-palmitoylation and disrupts membrane lipid raft composition
- Chronic O&NS causes depletion of n-3 polyunsaturated fatty acids in cell membranes
- These lipid changes increase membrane permeability and reduce membrane fluidity
- Disrupted lipid-based signaling leads to receptor dysfunction and increased neurotoxicity
- Palmitoylation and membrane lipid rafts are essential for proper glutamatergic neurotransmission and immune responses
Inferred Conclusions
- Lipid-based signaling disruption is a mechanistic pathway linking O&NS to neuroimmune pathology in ME/CFS and related disorders
- n-3 PUFA supplementation is a rational therapeutic target for restoring disrupted palmitoylation and lipid raft function
- Protecting or restoring these lipid signaling systems may ameliorate neurological and immune dysfunction in ME/CFS
Remaining Questions
- Is oxidative and nitrosative stress the primary driver of lipid-signaling disruption in ME/CFS, or a secondary consequence of other pathogenic processes?
- Do ME/CFS patients show measurably reduced palmitoylation, altered membrane lipid composition, or dysfunctional lipid rafts compared to healthy controls?
What This Study Does Not Prove
This is a narrative review, not a clinical trial or empirical study; it does not directly measure O&NS, palmitoylation, or lipid raft function in ME/CFS patients. The review does not prove that n-3 PUFA supplementation is effective in treating ME/CFS or that lipid-signaling disruption is the primary driver of disease rather than a secondary consequence.

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 →
