Into the Eye of the Cytokine Storm
Open accessAbstract
SUMMARY: The cytokine storm has captured the attention of the public and the scientific community alike, and while the general notion of an excessive or uncontrolled release of proinflammatory cytokines is well known, the concept of a cytokine storm and the biological consequences of cytokine overproduction are not clearly defined. Cytokine storms are associated with a wide variety of infectious and noninfectious diseases. The term was popularized largely in the context of avian H5N1 influenza virus infection, bringing the term into popular media. In this review, we focus on the cytokine storm in the context of virus infection, and we highlight how high-throughput genomic methods are revealing the importance of the kinetics of cytokine gene expression and the remarkable degree of redundancy and overlap in cytokine signaling. We also address evidence for and against the role of the cytokine storm in the pathology of clinical and infectious disease and discuss why it has been so difficult to use knowledge of the cytokine storm and immunomodulatory therapies to improve the clinical outcomes for patients with severe acute infections.

Written from the paper’s full text.
TL;DR
This review argues that “cytokine storm” remains poorly defined despite its broad use, and that severe infections with respiratory viruses such as influenza, SARS-CoV, and dengue can drive overlapping, redundant proinflammatory cytokine networks that contribute to immunopathology. It highlights genomic evidence for cytokine/chemokine kinetics and host genetic variation, but concludes that immunomodulatory therapies have largely failed to improve outcomes in acute severe infections.
Key findings
- The term “cytokine storm” lacks a precise definition; its first use appears in a 1993 graft-versus-host disease article, infectious-disease use began in early 2000, and it was first applied to avian H5N1 influenza in 2005. A Google search at the time yielded 323,000 hits, over 170,000 within the past year.
- In severe infection, plasma cytokines follow a sequence: TNF and IL-1β plus chemokines IL-8 and MCP-1 appear early (minutes to hours), IL-6 rises more sustainedly, and IL-10 appears later as a counter-anti-inflammatory response; persistent downregulation of monocyte HLA-DR 3 to 4 days after severe sepsis and cytokine storm is associated with high mortality.
- Genomic studies show early and sustained innate immune gene activation: a Vietnamese H5N1 case study compared 18 H5N1-infected people with 8 seasonal H1N1-infected people and found elevated MCP-1/CCL2, IP-10/CXCL10, MIG/CXCL9, and IL-8 in those progressing to severe lung injury; macaque H5N1 lung microarray analysis identified 45 significantly differentially expressed cytokine and chemokine genes.
- Host genetics shape susceptibility: a hyperfunctioning TLR1 variant was linked to increased organ dysfunction and morbidity from Gram-positive bacteremia; TLR4 Asp299Gly occurred at high frequency in Ghanaian children with severe malaria; CISH polymorphisms were associated with bacteremia, tuberculosis, and severe malaria across several populations; and IFN-λ variants were associated with HCV clearance/treatment response.
- Therapeutic attempts targeting the host response have mostly failed: corticosteroids, aspirin, monoclonal antibodies, anti-cytokine/anti-chemokine agents, plasma exchange, and statins have not been proven effective, and some worsened outcomes. In mice, S1P1-selective agonists protected against lethal pandemic H1N1 without affecting viral replication; gemfibrozil improved survival in H2N2-infected mice; and zanamivir plus celecoxib/mesalazine increased survival in highly pathogenic H5N1-infected mice.
Methods
- Design: narrative review of cytokine storm in infection, with emphasis on respiratory viruses (influenza, SARS-CoV, dengue) and on high-throughput genomic approaches.
- Data/sample: no primary dataset or new sample; the paper synthesizes published human clinical studies, animal models (mice, macaques, ferrets, pigs, rabbits), in vitro cell studies, and clinical trial reports.
- Main analysis: integrates cytokine biology, pathology, host genetics, functional genomics/microarray findings, knockout and transgenic mouse studies, and immunomodulatory drug studies to describe mechanisms and therapeutic challenges.
Limitations
- The paper states that an actual definition of cytokine storm is lacking, that molecular events precipitating it are poorly understood, and that its contribution to pathogenesis and optimal therapeutic strategies remain unclear.
- The paper states that most studies rely on intermittent sampling from one compartment, typically peripheral blood, and measure only a few cytokines/chemokines, failing to interrogate the whole immune cascade in tissues; it also notes no agreement on what should be measured or how NGS data should be analyzed, and that interdependent systems are often studied in silos.
- Evident from the text: this is a narrative review without a systematic search or meta-analysis, it reports no new primary data, and several key mechanistic conclusions derive from animal models that may not fully mimic human disease—the paper itself notes, for example, that no animal models mimic severe dengue in humans.

In the supplied Abstract passage, the authors postulate that immune dysregulation contributes to H5N1 disease and suggest that massive cytokine induction within the lung could contribute to its pathogenesis. They explicitly say they cannot determine whether elevated cytokines are a cause or a consequence of pneumonia, which is consistent with the claim's word “suspected.” (LLM, conf=0.87)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
A language model drew the claims from the paper on 2026-10-09, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-09 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Cited sources are checked with a language model’s help (gpt-6-sol).
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
