New Insights on the Role of TRP Channels in Calcium Signalling and Immunomodulation: Review of Pathways and Implications for Clinical Practice.
Froghi, Saied, Grant, Charlotte R, Tandon, Radhika et al. · Clinical reviews in allergy & immunology · 2021 · DOI
Quick Summary
This review examines how calcium moves into cells through special channels called TRP channels, and how this process affects the immune system. The authors explain that TRP channels play important roles in helping immune cells fight infections and respond to threats. They discuss evidence that problems with these calcium channels may be involved in several diseases, including ME/CFS.
Why It Matters
This review identifies TRP channels as potentially important regulators of immune dysfunction in ME/CFS, providing a molecular framework for understanding immune dysregulation in the disease. Understanding calcium signaling abnormalities could eventually lead to new diagnostic biomarkers or therapeutic targets specific to ME/CFS pathophysiology.
Observed Findings
- TRP channels are expressed across multiple immune cell types including T cells, B cells, dendritic cells, neutrophils, macrophages, and mast cells.
- TRP channels regulate diverse immune functions: T and B cell receptor signaling, antigen presentation, bactericidal activity, and mast cell degranulation.
- TRP channel dysfunction has been associated with multiple pathological conditions including inflammatory bowel disease, chronic fatigue syndrome/myalgic encephalomyelitis, atherosclerosis, hypertension, and atopy.
- TRP channels work alongside store-operated calcium entry (SOCE) mechanisms as alternative calcium influx pathways in immune cells.
Inferred Conclusions
- TRP channels represent an important but understudied mechanism of calcium signaling in immune system regulation.
- Dysfunction of TRP channels may contribute to pathological immune responses in multiple diseases, including ME/CFS.
- Therapeutic targeting of specific TRP channels could represent a novel treatment approach for immune-mediated conditions.
Remaining Questions
- Which specific TRP channel subtypes are dysfunctional in ME/CFS patients, and in which immune cell populations?
- Do TRP channel abnormalities cause immune dysfunction in ME/CFS, or are they secondary consequences of other pathological processes?
What This Study Does Not Prove
As a narrative review, this study does not provide direct experimental evidence that TRP channel dysfunction causes ME/CFS—it identifies associations and theoretical mechanisms. The review does not establish which specific TRP channels are dysfunctional in ME/CFS patients or prove causation rather than correlation with disease. The abstract does not describe how the authors selected or critically appraised included 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 →
