Level 5 - mechanism / opinion, no new human data
Narrative review synthesizing molecular mechanisms, signaling pathways, and therapeutic concepts without original data or systematic review methods.

What was done
This is a narrative review synthesizing literature on pathogen-associated molecular patterns (PAMPs) and damage-associated molecular patterns (DAMPs/alarmins). The authors describe their molecular sources, sensing mechanisms, regulatory networks, systemic functions (including trained immunity and interorgan communication), interplay between signals, roles across human diseases, and potential as biomarkers and therapeutic targets.
What was found
The abstract reports no quantitative data or specific empirical measurements. It describes an expanded conceptual framework where PAMPs and DAMPs act beyond localized defense cascades to orchestrate systemic physiological and pathological processes across immune and non-immune tissues.
Why it matters
The review organizes current understanding of danger-signal biology into a unified framework that includes modern concepts like trained immunity, offering a conceptual basis for developing pattern-recognition biomarkers and immunotherapies.
Limits
The paper is a broad narrative synthesis without original experimental or clinical data. The abstract provides no systematic search strategy, study selection criteria, formal quality assessment of cited studies, or quantitative findings.
