Modulation of Host Innate Immune Response by Highly Pathogenic Human Coronaviruses during Viral Infection.
Level 5 - mechanism / opinion, no new human data
Narrative review detailing viral mechanisms without original empirical human data or systematic synthesis
PubMed 42199010 · doi:10.4014/jmb.2602.02038
What was done
Narrative review synthesizing molecular and cellular mechanisms by which pathogenic human coronaviruses (SARS-CoV, SARS-CoV-2, and MERS-CoV) interact with host innate immune pathways, including cytoplasmic RNA sensors, Toll-like receptors, interferon signaling, and inflammasome activation.
What was found
The abstract provides a descriptive overview without reporting quantitative metrics or numerical findings. It outlines how these coronaviruses evade host innate immune detection and suppress early antiviral defenses while simultaneously triggering hyperinflammatory cascades (cytokine storms) associated with acute respiratory distress syndrome and multi-organ damage.
Why it matters
Synthesizes mechanistic pathways of immune evasion across major pathogenic coronaviruses, helping contextualize potential targets for antiviral and immunomodulatory interventions.
Limits
As a narrative review, it introduces no new primary experimental data and lacks systematic search methods, inclusion criteria, or quantitative synthesis. No specific sample sizes, effect sizes, or study counts are reported in the abstract.
